PART I

ITEM 1. BUSINESS

Overview

          Repros Therapeutics Inc. (“the Company”, “RPRX,” or “we,” “us” or “our”), was organized on August 28, 1987. We are a development stage biopharmaceutical company focused on the development of oral small molecule drugs for major unmet medical needs. We have a proven track-record of efficient and rapid advancement of our therapeutic candidates through clinical development.

          Our current product pipeline includes:

     Proellex

	•		Phase 3 for the treatment of anemia associated with uterine fibroids
	•		Phase 3 for the chronic treatment of uterine fibroids
	•		Phase 2 for the treatment of endometriosis

     Androxal

	•		Planned Phase 2b trial to treat men with AIHH, with concomitant plasma glucose and lipid elevations
	•		Planned Phase 2b trial in men with low testosterone levels wanting to improve or maintain their fertility and/or sperm function

          Our lead drug, Proellex^®, is a selective blocker of the progesterone receptor and is being developed for the treatment of uterine fibroids, anemia associated with excessive menstrual bleeding relating to uterine fibroids, or anemia associated with uterine fibroids, and endometriosis. During the first quarter of 2008 we filed an Investigational New Drug Application, or IND, for Proellex for the new indication of anemia associated with uterine fibroids. During the first quarter of 2008 we also initiated two 65 patient registration Phase 3 pivotal clinical trials with Proellex for this new indication, which will be conducted in approximately 15-20 sites in the United States and in several sites outside the United States. Our goal is to file a New Drug Application, or NDA, for this indication around year end 2008. During the first quarter of 2008 we also initiated two registration Phase 3 pivotal clinical trials with Proellex for the chronic treatment of uterine fibroids and two Open Label Safety Studies. We are also currently conducting a Phase 2 clinical trial with Proellex for the treatment of endometriosis.

          Uterine fibroids, anemia associated with uterine fibroids and endometriosis affect a significant number of women of childbearing age in the developed world. There is no currently-approved effective long-term drug treatment for uterine fibroids or endometriosis. In the United States alone, 300,000 women per year undergo a hysterectomy as a result of severe uterine fibroids.

          Our second product candidate, Androxal^®, is a single isomer of clomiphene citrate and is an orally active proprietary small molecule compound. We intend to initiate two proof-of-concept Phase 2b clinical trials with Androxal in the second quarter of 2008. One of these clinical trials will be in men with adult-onset idiopathic hypogonadotrophic hypogonadism, or AIHH, with concomitant plasma glucose and lipid elevations, all of which are components of Metabolic Syndrome. Recent published studies in older men show a link of low testosterone with higher incidences of insulin resistance, diabetes and consequently mortality rates. Based on a retrospective review of our recently completed six-month clinical trial with Androxal for the treatment of low testosterone due to secondary hypogonadism, our findings showed that Androxal therapy resulted in a significant reduction in mean glucose levels in men with a body mass index, or BMI, >26 and glucose levels >104 md/dL, an outcome not seen in the placebo or AndroGel^® arms of this study. AndroGel is the current leading therapy for testosterone replacement. The second Phase 2b Androxal clinical trial will be in men of reproductive age with low testosterone levels who want to improve or maintain their fertility and/or sperm function while being treated for low testosterone. We believe Androxal will be superior to the existing drugs used to normalize testosterone as only Androxal has the property of restoring both luteinizing hormone, or LH, and follicle stimulating hormone, or FSH, levels. LH and FSH are the pituitary hormones that stimulate testicular testosterone and sperm production, respectively. According to the Urology Channel, recent estimates show that approximately 13 million men in the United States experience testosterone deficiency.

          We were previously developing Androxal in the United States to treat testosterone deficiency due to secondary hypogonadism by restoring normal testosterone production in males with functional testes and diminished pituitary function, a common condition in the aging male. Based on a Type “C” meeting held with the Food and Drug Administration, or FDA, on October 15, 2007 we believe we do not have a clear clinical path to develop Androxal for this indication in the U.S. at this time. Although we believe Androxal could

be developed outside of the U.S., due to the limited European market for this indication and our limited internal resources we do not intend to pursue approval outside of the U.S. at this time.

Available Information

          Our Internet site (www.reprosrx.com) makes available free of charge to all interested parties our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports, as well as all other reports and schedules filed electronically with the SEC, as soon as reasonably practicable after such material is electronically filed with or furnished to the SEC. Interested parties may also find reports, proxy and information statements and other information on issuers that file electronically with the SEC at the SEC’s Internet site (http://www.sec.gov).

Business Strategy

          Our primary business strategy is to concentrate our resources on the clinical development of Proellex and Androxal. We intend to continue outsourcing the clinical development programs for both drugs and operate in a near virtual manner. We have no current plans to build manufacturing or sales and marketing capabilities and intend to seek a partner for assistance in the clinical development and commercialization of our products. We will seek to create value by developing our technologies to a point that one or more significant corporate license or strategic transactions can be completed. If necessary, we will seek to access the capital markets at appropriate times based on our clinical trial results and development needs.

Proellex

Product Overview

          Our lead product candidate, Proellex, is an orally active small molecule which we are developing for three indications: uterine fibroids, anemia associated with uterine fibroids and endometriosis. The National Uterine Fibroid Foundation estimates that as many as 80% of all women in the United States have uterine fibroids, and one in four of these women have symptoms severe enough to require treatment. According to The Endometriosis Association, endometriosis affects 5.5 million women in the United States and Canada and millions more worldwide.

          The current standards of care for uterine fibroids, anemia associated with uterine fibroids and endometriosis include surgery and treatment with drugs. The most effective drugs on the market are gonadotropin releasing hormone agonists, or GnRH agonists, such as Lupron^® (leuprolide acetate). GnRH is a peptide hormone that plays an important role in the regulation of the human reproductive system. Chronic administration of GnRH agonists reduce the number of GnRH receptors and thereby block the action of GnRH and its activity in stimulating the pituitary to secrete FSH and LH.

          GnRH agonists induce a low estrogen, menopausal-like state in women. Because estrogen is necessary for the maintenance of bone mineral density, GnRH agonists tend to promote bone loss and are not recommended to be used for more than six months at a time. When women cease treatment with GnRH agonists, fibroids generally regenerate rapidly in the case of uterine fibroids and symptoms associated with endometriosis generally reappear quickly in the case of endometriosis.

          We believe Proellex may have advantages in treating uterine fibroids, anemia associated with uterine fibroids and endometriosis compared to treatment with GnRH agonists. In our clinical trials, which are consistent with our preclinical studies, women treated with Proellex maintain baseline estrogen levels. Therefore, we believe Proellex treatment may not result in estrogen deprivation mediated loss of bone mineral density. We believe Proellex may provide an attractive alternative to surgery because of its potential to treat these conditions in a long-term or chronic fashion, resolving the symptoms that most commonly lead to surgical treatment.

          Proellex is a new chemical entity, which means that the compound will be required to undergo the full regulatory approval process. We must still meet additional clinical requirements including pre-clinical, Phase 1, Pivotal Phase 3 trials, long-term Open Label Safety Studies as well as other requirements. Among other requirements is a two-year carcinogenicity study, which we expect to complete in the second half of 2008 as well as other preclinical studies which have either been initiated or completed. We have completed a nine-month primate study to evaluate the effects of Proellex on the endometrium. This study showed no significant toxicity at any dose, with the highest dose comparable to the highest dose in our clinical trials.

          All clinical trial results are subject to review by the FDA, and the FDA may disagree with our conclusions about safety and efficacy. We caution that the results discussed herein are based on data from non-pivotal trials and that our pivotal Phase 3 and long-term Open Label Safety Study data may not agree with these results which will be based upon a significantly larger and more diverse patient population treated for longer periods of time.

Anemia Associated with Uterine Fibroids

          Current Phase 3 Trials. A new IND for Proellex as a pre-surgical short course treatment of anemia due to uterine fibroids became effective in February 2008. In the first quarter of 2008 we contracted two clinical research organizations, or CROs, to conduct our registration Phase 3 pivotal clinical trials and began selecting the clinical sites that will conduct these trials.

          We initiated this new clinical indication of Proellex based upon the results observed from a subset of anemic patients in our U.S. Phase 2 trial with Proellex for the treatment of uterine fibroids which was completed in 2007. In that study, women with hemoglobin levels of less than 11.5 g/dl improved by up to 2 g/dl, or the equivalent of two pints of blood, after three months of treatment with Proellex. Even though only approximately 15-17 patients per active treatment arm were able to be evaluated for anemia, the improvement of hemoglobin in Proellex-treated subjects was both clinically and statistically highly significant (p<0.002) compared with placebo. Oral iron supplements for correction of anemia were used by a similar number of women in the placebo and 25 mg Proellex arms of the trial. A slightly higher percentage of women in the Proellex 12.5 mg arm used oral iron supplements. This suggests that reversal of the anemia with Proellex treatment was largely due to the very effective prevention of severe blood loss experienced by these patients with symptomatic uterine fibroids.

          We intend to conduct one of the treatment for anemia associated with uterine fibroids registration Phase 3 pivotal clinical trials in 15 to 20 locations in the United States, and intend to conduct the other registration Phase 3 clinical pivotal trial in several locations outside of the United States. The trials will consist of three parallel arms each consisting of placebo, 25 and 50 mg Proellex. Each trial will enroll 65 patients unevenly distributed between placebo (15 patients) and 25 and 50 mg Proellex (25 patients each). Patients will be treated with Proellex or placebo for three months. The primary endpoint of both of these clinical trials is improvement in hemoglobin concentration. All patients will receive a fixed dose of daily iron supplementation as well.

          Development Plan. In addition to our Phase 3 pivotal trials listed above, the FDA will require data from 100 patients that have been exposed to Proellex for a six-month period. We anticipate that a NDA for Proellex for the treatment of anemia associated with uterine fibroids will be filed around the end of 2008. Such filing depends on a variety of factors, including the timing of enrollment of patients in our two clinical trials as well as the outcome and results of such clinical trials. We will also have to provide the FDA with data from additional Phase 1 studies, other safety and efficacy data as requested, preclinical safety data and meet all manufacturing requirements. No assurance can be given that such filing will be made at such time or at all.

Uterine Fibroids

          We completed a Phase 2 clinical trial with Proellex for the treatment of uterine fibroids during 2007. This study consisted of 128 patients in a randomized, double-blind, placebo-controlled trial. The analysis of the clinical trial data demonstrated statistically significant reductions in excessive menstrual bleeding and an improvement in quality of life scores versus placebo. Furthermore, after three months of treatment, no statistically significant change in endometrial thickness was observed. This trial was designed to assess both improvement of symptoms associated with uterine fibroids as well as effects on the actual fibroids. The three-arm trial compared two doses of Proellex, 12.5 mg and 25 mg, to placebo over a 3-month period. The primary endpoint was a reduction in excessive menstrual bleeding, a common symptom of uterine fibroids. This endpoint was assessed using a visual analog scale known as the Pictorial Blood Loss Assessment Chart, or PBAC. Various other symptoms associated with fibroids were assessed using the validated Uterine Fibroid Symptom and Quality of Life, or UFS-QOL, questionnaire. Patients that completed the blinded portion of this clinical trial have been enrolled into a 12-month open label safety extension study.

          Current Phase 3 Trials. As a result of our Type B meeting with the FDA at the end of November 2007, two registration Phase 3 pivotal four-month double blind placebo controlled clinical trials with Proellex for the treatment of uterine fibroids have been initiated in the first quarter of 2008. We have contracted two CROs to conduct our registration Phase 3 pivotal clinical trials and began selecting the clinical sites that will conduct these trials.

          We intend to conduct one of the planned Phase 3 clinical trials in 15 to 20 locations in the United States, and intend to conduct the other Phase 3 clinical trial in several locations outside of the United States. Each trial will enroll 75 patients evenly distributed between placebo and 25 and 50 mg Proellex.

          Current and Upcoming Open Label Safety Studies. We are currently conducting a small 12-month open label safety extension study with enrolled patients from our previously completed U.S. Phase 2 clinical trial. We intend to provide interim safety data from this study around the end of the first quarter of 2008.

          We also initiated two long-term Open Label Safety Studies during the first quarter of 2008. We have contracted with one CRO to conduct both studies that will enroll patient in the U.S. as well as outside of the U.S. and we are currently selecting the clinical sites that will be used to conduct these studies.

          The first long-term 400 patient Open Label Safety Study to be enrolled is a twelve month on drug study which will incorporate two off-drug intervals between three four-month drug treatment periods. After patients complete a four-month course of treatment

they will be taken off the drug until they menstruate normally before commencing further treatment then they will begin the next four-month drug treatment until three drug treatments have been completed.

          The second long-term 400 patient Open Label Safety Study will enroll patients after the initial 400 patient Open Label Safety Study has been fully recruited. This study will consist of two four-month drug treatment periods separated by one off-drug interval. After patients complete a four-month course of treatment they will be taken off the drug until their symptoms return and then they will begin the final four-month drug treatment period.

          Development Plan. In addition, to our ongoing two Phase 3 trials the FDA will require data from 200 patients that have been exposed to Proellex for one year with the final duration of drug exposure to be determined as data from ongoing trials continues to evolve. We will also need to provide the FDA with data from approximately 300 to 600 patients that have been on Proellex for six months. The FDA has suggested a total safety data base of 1,500 patients which we may derive from all of our trials and studies of Proellex for all indications, doses and durations of exposure.

          We anticipate that a NDA for this indication will be filed in the fourth quarter of 2009. Such filing depends on a variety of factors, including the timing of enrollment of patients in the two pivotal clinical and open label safety trials described above as well as the outcome and results of the trials. We will also incorporate any data submitted in the NDA for the anemia associated with uterine fibroids indication into this NDA submission as well as any other additional data that the FDA may require. No assurance can be given that such filing will be made at such time or at all.

Endometriosis

          Current Phase 2 Trial. We are currently conducting a 75 patient U.S. Phase 2 clinical trial with Proellex for the treatment of endometriosis. Such trial is being conducted in up to 20 clinical sites in the United States. This trial is designed to assess the improvement of symptoms associated with endometriosis. The trial will test two doses of Proellex, 25mg and 50mg, as a once-a-day oral therapy versus placebo in a double-blind design and will be four months in duration. The trial will use a daily diary into which patients record their endometriosis symptom scores as a primary endpoint. Per a request from the FDA, the diary was derived from the symptom section of the previously validated Biberoglu and Behrman Symptom Score, or BBSS. In addition, the BBSS which has a physical examination component will be physician administered at monthly intervals requiring patient recollection of symptoms over the previous month. The endometrium, or lining of the uterus, will be monitored monthly using ultrasound and endometrial biopsies which will be done at baseline and the end of four months treatment exposure. The four-month duration of the trial is similar to the duration of treatment in previously conducted trials with Proellex. After the double-blind treatment period, patients will be followed up for up to six months to observe for a return of symptoms. An Open Label Safety Extension Study for the patients enrolled in the trial will be submitted under a separate protocol. If accepted, the extension study will allow for patients to be treated for two additional four-month cycles with an intervening menstruation between each cycle if symptoms recur.

          Doses used in this trial were previously tested in a 24-week clinical trial with Proellex for the treatment of endometriosis in 40 patients which was conducted in Bulgaria. The trial compared Proellex to Lucrin^®, also known as Lupron^®, an approved GnRH agonist, commonly used to treat the symptoms associated with endometriosis. The 50mg dose of Proellex achieved statistical significance (p=0.0012) when compared to Lucrin in reducing the number of days of pelvic abdominal pain over the course of the trial. In addition a statistically significant greater percentage of patients had a reduction in pain in the 50 mg treatment arm compared with the other treatments. There was no statistical difference between the 25 mg dose of Proellex and Lucrin. There was a clear dose response in the Proellex treatment groups, and Proellex was well tolerated over the course of the trial.

          Management of Increasing Endometrial Thickening and Uterine Bleeding. During the six month study of endometriosis in Bulgaria it was observed that the development of endometrial thickening was dependent on duration of exposure and the dose that was used. In summary, the lower the dose and the longer the exposure beyond 4 months, the greater the risk became for endometrial thickening and severe uterine bleeding. Four instances of severe bleeding, all managed successfully by intervention with Dilatation and Curettage, occurred after 5 months. In addition there was a very strong tendency for endometrial thickening to occur in the 12.5 mg dose by month three of exposure. These results were corroborated by the fact that none of the 127 women in the U.S. Phase 2 uterine fibroid study, who were exposed to treatment for 3 months, had similar events. The increase in endometrial thickening correlates well with the development of cystic dilatation of the glands in the endometrium which has been observed histologically on endometrial biopsy. These observations have led Repros to develop a proactive strategy to manage these events. A dosing regimen consisting of sequential four-month treatment cycles, each followed by an ‘off drug interval’, in order to refresh the endometrium after a withdrawal bleed has occurred, has been developed and we believe this treatment regimen will allow Proellex^® to be used in a safe and practical manner for longer term treatment exposures and subsequently avoid the development of endometrial thickening with the attendant risk of severe bleeding.

          Development Plan. Pending positive results from our ongoing Phase 2 trial and FDA acceptance of clinical protocols, we plan to initiate registration Phase 3 pivotal trials. We intend to file a NDA for endometriosis during the first half of 2010. Such filings

depend on a variety of factors, including the timing of enrollment of patients in the trials as well as the outcome and results of the trials. No assurance can be given that such filings will be made at such time or at all.

Androxal

Product Overview

          Our second product candidate, Androxal (the trans isomer of clomiphene), is a single isomer of clomiphene citrate and is an orally active proprietary small molecule compound. We intend to submit two white papers to the FDA. One white paper will be submitted for the commencement of a proof of concept Phase 2b clinical trial to elucidate Androxal’s effect on fertility. The second white paper will be for the commencement of a proof of concept Phase 2b clinical trial to elucidate Androxal’s effect on metabolic dysregulation of blood glucose, cholesterol and triglycerides in men with AIHH and for the FDA to consider whether the current Androxal IND should be moved to the FDA’s Metabolic and Endocrine Division. Both Phase 2b clinical trials are expected to be small studies that are anticipated to begin during the second quarter of 2008 and last approximately 12 months. Subsequent to the completion and success of each of the proposed Phase 2b clinical trials the Company intends to submit a protocol to begin a pivotal Phase 3 trial for both of these indications.

          Data relating to the findings of Androxal’s beneficial effect on fertility and as a treatment for AIHH associated with glucose and lipid dysregulation was discovered after a retrospective review of our clinical data from our 200 patient non-pivotal U.S. Phase 3 clinical trial. Our findings showed that Androxal therapy resulted in a significant reduction in mean glucose levels in men with a body mass index, or BMI, >26 and glucose levels >104 mg/dL, an outcome not seen in the placebo or AndroGel^® arms of this study. AndroGel is the current leading therapy for testosterone replacement. Men with AIHH are characterized as having both low testosterone and LH, often accompanied by obesity and elevated blood glucose, among other signs. Our clinical trial data suggests that Androxal modifies the endocrinologic profile in terms of both hormones and glucose. There can be no assurance that clinical trials performed for these two new indications will be successful.

          We believe Androxal will be superior to the existing administration of exogenous testosterone products used to normalize testosterone as only Androxal has the property of restoring both LH and FSH levels. LH and FSH are the pituitary hormones that stimulate testicular testosterone and sperm production, respectively.

          Previously we were developing Androxal in the United States to treat testosterone deficiency due to secondary hypogonadism by restoring normal testosterone production in males with functional testes and diminished pituitary function, a common condition in the aging male. Based on a Type “C” meeting with the FDA on October 15, 2007 we believe we do not have a clear clinical path to develop Androxal for this indication in the U.S. at this time. Although we believe Androxal could be developed outside of the U.S., due to the limited European market for this indication and our limited internal resources we do not intend to pursue approval outside of the U.S. at this time for the treatment of secondary hypogonadism.

          We believe Androxal may have advantages over current therapies for the treatment of low testosterone due to secondary hypogonadism because it is designed as an oral therapy that acts centrally to restore normal testosterone function in the body, as compared to currently approved products that simply replace diminished testosterone either through injections, nasal spray or the application of a gel or cream containing testosterone over a large percentage of body area. The administration of replacement testosterone has been linked to numerous potential adverse effects, including shrinkage of the testes. We believe that Androxal may not cause these adverse effects to the extent that such other replacement therapies do.

          Testosterone is an important male hormone. Testosterone deficiency in men is linked to several negative physical and mental conditions, including loss of muscle tone, reduced sexual desire, and deterioration of memory and certain other cognitive functions. Testosterone production normally decreases as men age, sometimes leading to testosterone deficiency. According to the Urology Channel, recent estimates show that approximately 13 million men in the United States experience testosterone deficiency. The leading therapy is AndroGel, a commercially available testosterone replacement cream marketed by Solvay Pharmaceuticals for the treatment of low testosterone, which had reported sales of approximately $282 million in 2005 in North America.

          Based on our own clinical trial screening data, we believe over 70% of men that have low testosterone suffer from secondary hypogonadism, caused by failure of the pituitary to provide appropriate hormone signaling to the testes, which we believe causes testosterone levels to drop to the point where pituitary secretions fall under the influence of estrogen. In this state, we also believe that estrogen further suppresses the testicular stimulation from the pituitary. These men are readily distinguished from those that have primary testicular failure via assessment of the levels of secretions of pituitary hormones (i.e., men with primary testicular failure experience elevated secretions of pituitary hormones). Secondary hypogonadism is not relegated only to older men although the condition becomes more prevalent as men age.

          Androxal is being considered as a new chemical entity by the FDA which means that the compound will be required to undergo the full regulatory approval process. We must still meet additional clinical requirements including pre-clinical, Phase 1, Phase 2b

trials, pivotal Phase 3 trials, long-term Open Label Safety Studies as well as other requirements. Among other requirements, this includes a two-year carcinogenicity study, which we began in September 2006. Although Androxal is considered a new chemical entity for purposes of requirements for approval, it is closely related chemically to the drug, Clomid^®, which is approved for use in women to treat certain infertility disorders. The FDA has indicated that testicular tumors, gynecomastia and adverse ophthalmologic events, which have been reported in males taking Clomid, are potential risks that should be included in informed consent forms for our Androxal clinical trials. We do not believe that Androxal will present with the same adverse events given its accelerated half-life in the human body as compared to Clomid. In our preclinical studies and our clinical trials to date, we have observed no evidence of any of these events except for certain adverse ophthalmologic events in our preclinical study at doses significantly higher than those administered in the clinical trials.

          All clinical trial results are subject to review by the FDA, and the FDA may disagree with our conclusions about safety and efficacy. We caution that the results discussed herein are based on data from non-pivotal trials and that our Phase 2b trials, pivotal Phase 3 and long-term Open Label Safety Trial data may not agree with these results which will be based upon a significantly larger and more diverse patient populations treated for longer periods of time.

Secondary Hypogonadism with Fertility Maintenance/Improvement

Development Plan. We intend to initiate a small Phase 2b proof of concept clinical trial to elucidate Androxal’s effect on fertility. This clinical trial is anticipated to begin in the second quarter of 2008 and we anticipate providing data from this clinical trial in the second quarter of 2009.

          Post successful results from our proposed Phase 2b clinical trial and preclinical studies and acceptance by the FDA, we intend to initiate Phase 3 clinical trials for this indication in the third quarter of 2009.

Secondary Hypogonadism and AIHH

Development Plan. We intend to initiate a small Phase 2b proof of concept clinical to elucidate Androxal’s effect relating to AIHH. This clinical trial is anticipated to begin in the second quarter of 2008 and we anticipate providing data from this clinical trial in the second quarter of 2009.

          Post successful results from our proposed Phase 2b clinical trial and preclinical studies and acceptance by the FDA, we intend to initiate Phase 3 clinical trials for this indication in the third quarter of 2009.

Secondary Hypogonadism

Development Plan. Based on a Type “C” meeting with the FDA on October 15, 2007 we believe we do not have a clear clinical path to develop Androxal for this indication in the U.S. at this time. Although we believe Androxal could be developed outside of the U.S., due to the limited European market for this indication and our limited internal resources we do not intend to pursue approval outside of the U.S. at this time for the treatment of secondary hypogonadism.

Current Open Label Extension Safety Study. Our one-year Open Label Safety Study with Androxal for the treatment of male secondary hypogonadism is still ongoing. We believe safety data derived from this study will be applicable for our two new indications with Androxal.

Other Products

          We continue limited out-licensing efforts for our phentolamine-based product candidates, including VASOMAX^®, which had previously been approved for marketing in several countries in Latin America for the treatment of male erectile dysfunction under the brand name, Z-Max. VASOMAX is currently on partial clinical hold in the U.S.

Research and Development

          We have limited resources and utilize consultants and outside entities to perform clinical development and limited research activities in connection with preclinical studies and clinical trials. Our primary research and development, or R&D, expenses for 2007 were for the payment and contract research organizations and consultants in connection with our clinical trials of Proellex for the treatment of uterine fibroids, endometriosis and for Androxal for testosterone deficiency. We believe that these expenses will continue to be our primary R&D expenses in the near future.

Agreement with National Institutes of Health

     In 1999, we licensed rights to Proellex from the NIH under an exclusive, worldwide license in the field of treatment of human endocrinologic pathologies or conditions in steroid sensitive tissues which expires upon the expiration of the last licensed patent. Under the terms of the agreement, we are obligated to meet developmental milestones as outlined in a commercial development plan.

This development plan outlines a preclinical and clinical program leading to the stated objective of submitting an NDA for regulatory approval of Proellex for the treatment of uterine fibroids in 2008. We provide annual updates to the NIH on the progress of our development of Proellex. Based on our interaction with the NIH to date, we believe our license and relationship with NIH are in good standing. The NIH has the ability to terminate the agreement for lack of payment or if we are not meeting milestones as outlined in the commercial development plan and for other reasons as outlined in the agreement. Although we believe that we have a good working relationship with the NIH, there can be no assurance that all of the objectives and conditions in the commercial development plan will be met on a timely basis or at all, or that, if we fail to meet any of such objectives, the NIH will again agree to amend this agreement to our satisfaction. Failure to comply with the material terms contained in the license agreement could result in termination of such agreement, which would prohibit us from further development of Proellex and severely harm our business prospects. The NIH retains, on behalf of the government, a nonexclusive, nontransferable, worldwide license to practice the inventions licensed under the licensed patents by or on behalf of the government. For the purpose of encouraging basic research, the NIH retains the right to grant nonexclusive research licenses to third parties. Due to the work that was done on Proellex at the NIH prior to our license agreement, the government also has certain rights to use the product in the event of a national emergency pursuant to the Patent and Trademark Laws Amendments Act of 1980, as amended. In the early part of our relationship with the NIH under this agreement, we were not in compliance with all of the original requirements stated in the commercial development plan. In July 2002, we and the NIH amended the license agreement to include a revision of the original commercial development plan relating to the target dates for certain objectives. Since then, we have entered into additional updates of the original commercial development plan with the NIH relating to such target dates.

Manufacturing

     Currently, we do not have the ability internally to manufacture the product candidates that we need to conduct our clinical trials. In 2006, we entered into a development and supply contract with Gedeon Richter for the production of the active pharmaceutical ingredient, or API, for Proellex due to their extensive experience in the manufacture of similar compounds and the cost savings they offered compared to other qualified manufacturers. Pursuant to the terms of this supply contract, we are required, with certain limited exceptions, to purchase all of our future requirements of Proellex from this single supplier for a period of five years after the first sale of Proellex in the United States, to the extent that such supplier is able to satisfy our requirements. The contract may be terminated by either party for failure to remedy a default of any material provision of the contract. Should the contract be terminated for any reason, we would in all likelihood be required to obtain the API from an alternate manufacturer which may increase the costs associated with our clinical trials and result in delays to our clinical trial program for Proellex.

     We have a five year supply agreement with Diagnostic Chemical Limited, doing business as BioVectra, for the supply of the bulk active pharmaceutical ingredient used in Androxal. We have obtained all of our supply of Androxal to date from BioVectra. We have not faced any material problems with BioVectra in supplying us with our necessary quantities of Androxal for our clinical trials and anticipate utilizing them for commercial production if Androxal is approved. There are numerous other suitable manufacturers capable of manufacturing Androxal.

     For the foreseeable future, we expect to continue to rely on third-party manufacturers and other third parties to produce, package and store sufficient quantities of Proellex, Androxal and any future product candidates for use in our clinical trials. These product candidates are complicated and expensive to manufacture. If our third-party manufacturers fail to deliver our product candidates for clinical use on a timely basis, with sufficient quality, and at commercially reasonable prices, we may be required to delay or suspend clinical trials or otherwise discontinue development and production of our product candidates. While we may be able to identify replacement third-party manufacturers or develop our own manufacturing capabilities for these product candidates, this process would likely cause a delay in the availability of our product candidates and an increase in costs. In addition, third-party manufacturers may have a limited number of facilities in which our product candidates can be produced, and any interruption of the operation of those facilities due to events such as equipment malfunction or failure or damage to the facility could result in the cancellation of shipments, loss of product in the manufacturing process or a shortfall in available product candidates.

Sales and Marketing

          We have no experience in the sales, marketing and distribution of pharmaceutical products. We anticipate that we will outsource such activities, as well as possibly later stage pivotal trials of our product candidates, to larger pharmaceutical companies more capable of distributing the products to the market place. In the normal course of business we continue to explore possible partnerships with various pharmaceutical companies. If in the future we fail to reach or elect not to enter into an arrangement with a collaborative partner with respect to the sales and marketing of any of our future potential product candidates, we would need to develop a sales and marketing organization with supporting distribution capability in order to market such products directly. Significant additional expenditures would be required for us to develop such a sales and marketing organization.

Patents and Proprietary Information

          Our ability to compete effectively with other companies is materially dependent on the proprietary nature of our patents and technologies. We actively seek patent protection for our proprietary technology in the United States and abroad.

          Under a license agreement with the National Institutes of Health, we have exclusive rights to three issued U.S. patents, which expire in 2017, two pending U.S. patent applications, and a foreign filing made by the NIH regarding Proellex. We also have one provisional U.S. patent application and four foreign PCT applications that cover various formulations of Proellex and methods for using Proellex.

          Our Androxal product candidate and its uses are covered in the United States by one issued U.S. patent and eight pending patent applications. Foreign coverage of our Androxal product candidate includes seven issued foreign patents and 70 foreign pending patent applications. The issued patents and pending applications relate to methods and compositions for treating certain conditions including the treatment of testosterone deficiency in men, the treatment of metabolic syndrome and conditions associated therewith, and the treatment of infertility in hypogonadal men. Androxal (the trans isomer of clomiphene) is purified from clomiphene citrate. A third party individual holds two issued patents related to the use of an anti-estrogen such as clomiphene citrate and others for use in the treatment of androgen deficiency and disorders related thereto. In our prior filings with the SEC, we have described our request to the U.S. Patent and Trademark Office, or PTO, for re-examination of one of these patents based on prior art. The third party amended the claims in the reexamination proceedings, which led the PTO to determine that the amended claims are patentable in view of those publications under consideration and a reexamination certificate was issued. However, we believe that the amended claims are invalid based on additional prior art publications, and our request for reexamination by the PTO in light of a number of these additional publications and other publications cited by the PTO, has been granted. In November, 2007, the PTO issued a final Office action, rejecting all of the claims. In January, 2008, the patent holder responded to the final Office action. In February, 2008, the PTO issued an Advisory Action stating that the patent holder’s response failed to overcome the rejections. The patent holder has filed a Notice of Appeal. We also believe that the second of these two patents is invalid in view of published prior art not considered by the PTO. Nevertheless, there is no assurance that either patent will ultimately be found invalid over the prior art. If such patents are not invalidated by the PTO we may be required to obtain a license from the holder of such patents in order to develop Androxal further or attempts may be made to undertake further legal action to invalidate such patents. If such licenses were not available on acceptable terms or at all, we may not be able to successfully commercialize Androxal.

          All of our employees and consultants have signed assignment of invention and confidentiality agreements, and each corporate partner we enter into discussions with or engage to assist in our clinical trials or manufacturing process is also required to execute appropriate confidentiality and assignment agreements protecting our intellectual property.

Competition

          We are engaged in pharmaceutical product development, an industry that is characterized by extensive research efforts and rapid technological progress. Many established pharmaceutical and biotechnology companies, universities and other research institutions with financial, scientific and other resources significantly greater than ours are marketing or may develop products that directly compete with any products we may develop. These entities may succeed in developing products that are safer, more effective or less costly than products we may develop. Even if we can develop products which should prove to be more effective than those developed by other companies, other companies may be more successful than us because of greater financial resources, greater experience in conducting preclinical studies and clinical trials and in obtaining regulatory approval, stronger sales and marketing efforts, earlier receipt of approval for competing products and other factors. If we commence significant commercial sales of any products, we or our collaborators may compete in areas in which we have no experience, such as manufacturing and marketing. There can be no assurance that our products, if commercialized, will be accepted and prescribed by healthcare professionals.

          Our main competitors for the treatment of uterine fibroids and endometriosis are GnRH agonists, especially Lupron, the current most common therapeutic standard of care for uterine fibroids. Lupron^® is marketed by TAP Pharmaceuticals, which has far greater resources and marketing capabilities than we have. In addition, surgical treatment of both uterine fibroids and endometriosis competes with Proellex by removing uterine fibroids and by removing misplaced tissue in women with endometriosis. We believe we can potentially compete with Lupron and other GnRH agonists because we believe that Proellex will not present the same side effect of a decrease in bone mineral density given its specific focus on progesterone inhibition, which differentiates it from GnRH agonists that create a low estrogen state. There are additional companies developing similar progesterone-blocking technology. Asoprisnil, an anti-progestin being developed by TAP Pharmaceuticals in partnership with Schering AG, has been tested up through Phase 3 clinical trials.

          Our main competitors for the treatment of testosterone deficiency are the testosterone replacement therapies currently being marketed. The current most common standard of care is AndroGel, a topical gel for the replacement of testosterone, with 2005 sales of $282 million in North America. AndroGel is marketed by Solvay Pharmaceuticals, a considerably larger company than we are. There is another topical gel, Testim^®, currently marketed by Auxilium Pharmaceuticals, and a transdermal patch, AndroDerm^®,

marketed by Watson Pharmaceuticals. In addition, other companies such as QTRX Pharmaceuticals are developing other products that would compete with Androxal. We believe we can compete with AndroGel and the other replacement therapies because we believe that Androxal avoids the abnormally high peaks of testosterone levels and elevated levels of DHT which can be associated with current testosterone replacement therapies like AndroGel. Based on our clinical trial supply cost to date, we currently expect that Androxal, if approved, can compete favorably on a cost basis with current testosterone replacement therapies.

Governmental Regulation

          Our research and development activities, preclinical studies and clinical trials, and the manufacturing, marketing and labeling of any products we may develop, are subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries. The U.S. Federal Food, Drug, and Cosmetic Act and the regulations promulgated thereunder and other federal and state statutes and regulations govern, among other things, the testing, manufacture, storage, record keeping, labeling, advertising, promotion, marketing and distribution of any products we may develop. Preclinical study and clinical trial requirements and the regulatory approval process take many years and require the expenditure of substantial resources. Additional government regulation may be established that could prevent or delay regulatory approval of our product candidates. Delays in obtaining or rejections of regulatory approvals would adversely affect our ability to commercialize any product candidate we develop and our ability to receive product revenues or to receive milestone payments or royalties from any product rights we might license to others. If regulatory approval of a product candidate is granted, the approval may include significant limitations on the indicated uses for which the product may be marketed or may be conditioned on the conduct of post-marketing surveillance studies.

          The standard process required by the FDA before a pharmaceutical agent may be marketed in the United States includes: (1) preclinical tests; (2) submission to the FDA of an IND application which must become effective before human clinical trials may commence; (3) adequate and well-controlled human clinical trials to establish the safety and efficacy of the drug for its intended application; (4) submission of a new drug application, or NDA, to the FDA; and (5) FDA approval of the NDA prior to any commercial sale or shipment of the drug.

          Clinical trials typically are conducted in three sequential phases, but the phases may overlap. Phase 1 typically involves the initial introduction of the drug into human subjects. In Phase 1, the drug is tested for safety and, as appropriate, for absorption, metabolism, distribution, excretion, pharmacodynamics and pharmacokinetics. Phase 2 usually involves studies in a limited patient population to evaluate preliminarily the efficacy of the drug for specific targeted indications, determine dosage tolerance and optimal dosage and identify possible adverse effects and safety risks.

          Phase 3 clinical trials are undertaken to further evaluate clinical efficacy and to test further for safety within an expanded patient population at geographically dispersed clinical study sites. Phase 1, Phase 2 or Phase 3 testing may not be completed successfully within any specific time period, if at all, with respect to any products being tested by a sponsor. Furthermore, the FDA or the Investigational Review Board, or IRB may suspend clinical trials at any time on various grounds, including a finding that the healthy volunteers or patients are being exposed to an unacceptable health risk.

          Even if regulatory approvals for any products we may develop are obtained, we, our potential collaborators, our products, and the facilities manufacturing our products would be subject to continual review and periodic inspection. The FDA will require post-marketing reporting to monitor the safety of our products. Each drug-manufacturing establishment supplying the United States must be registered with the FDA. Manufacturing establishments are subject to periodic inspections by the FDA and must comply with the FDA’s requirements regarding current Good Manufacturing Practices, or GMP. In complying with current GMP, manufacturers must expend funds, time and effort in the area of production and quality control to ensure full technical compliance. We do not have any drug manufacturing capabilities and must rely on outside firms for this capability. The FDA stringently applies regulatory standards for manufacturing. Identification of previously unknown problems with respect to a product, manufacturer or facility may result in restrictions on the product, manufacturer or facility, including warning letters, suspensions of regulatory approvals, operating restrictions, delays in obtaining new product approvals, withdrawal of the product from the market, product recalls, fines, injunctions and criminal prosecution.

          Before any products we may develop could be marketed outside of the United States, they would be subject to regulatory approval similar to FDA requirements in the United States, although the requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary widely from country to country. No action can be taken to market any drug product in a country until the regulatory authorities in that country have approved an appropriate application. FDA approval does not assure approval by other regulatory authorities. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In some countries, the sale price of a drug product must also be approved. The pricing review period often begins after market approval is granted. Even if a foreign regulatory authority approves any products we may develop, no assurance can be given that it will approve satisfactory prices for the products.

          Our research and development involves the controlled use of hazardous materials and chemicals. Although we believe that our procedures for handling and disposing of those materials comply with state and federal regulations, the risk of accidental

contamination or injury from these materials cannot be eliminated. If such an accident occurs, we could be held liable for resulting damages, which could be material to our financial condition and business. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens, and the handling of biohazardous materials. Additional federal, state and local laws and regulations affecting us may be adopted in the future. Any violation of, and the cost of compliance with, these laws and regulations could materially and adversely affect us.

          Third-Party Reimbursement and Pricing Controls

          In the United States and elsewhere, sales of pharmaceutical products depend in significant part on the availability of reimbursement to the consumer from third-party payers, such as government and private insurance plans. Since we have no commercial products, we have not had to face this issue yet. However, third-party payers are increasingly challenging the prices charged for medical products and services. It will be time consuming and expensive for us to go through the process of seeking reimbursement from Medicaid, Medicare and private payers.

          Our products may not be considered cost effective, and coverage and reimbursement may not be available or sufficient to allow us to sell our products on a competitive and profitable basis. The passage of the Medicare Prescription Drug and Modernization Act of 2003 imposes new requirements for the distribution and pricing of prescription drugs which may affect the marketing of our products.

          In many foreign markets, including the countries in the European Union, pricing of pharmaceutical products is subject to governmental control. In the United States, there have been, and we expect that there will continue to be, a number of federal and state proposals to implement similar governmental pricing control. While we cannot predict whether such legislative or regulatory proposals will be adopted, the adoption of such proposals could have a material adverse effect on our profitability.

          The Hatch-Waxman Act

          Under the U.S. Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Act, newly approved drugs and indications benefit from a statutory period of non-patent marketing exclusivity. The Hatch-Waxman Act provides five year marketing exclusivity to the first applicant to gain approval of an NDA for a new chemical entity, or NCE, meaning that the FDA has not previously approved any other new drug containing the same active ingredient. Both of our current product candidates are considered NCEs. The Hatch-Waxman Act prohibits approval of an abbreviated new drug application, or ANDA, for a generic version of the drug during the five-year exclusivity period. Protection under the Hatch-Waxman Act will not prevent the filing or approval of another full NDA, however, the applicant would be required to conduct its own adequate and well-controlled clinical trials to demonstrate safety and effectiveness. The Hatch-Waxman Act also provides three years of marketing exclusivity for the approval of new NDAs with new clinical trials for previously approved drugs and supplemental NDAs, for example, for new indications, dosages, or strengths of an existing drug, if new clinical investigations are essential to the approval. This three year exclusivity covers only the new changes associated with the supplemental NDA and does not prohibit the FDA from approving ANDAs for drugs containing the original active ingredient or indications.

          The Hatch-Waxman Act also permits a patent extension term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent extension cannot extend the remaining term of a patent beyond a total of 14 years. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA, plus time of active FDA review between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and it must be applied for prior to expiration of the patent and within 60 days of the approval of the NDA. The PTO, in consultation with the FDA, reviews and approves or rejects the application for patent term extension.

Litigation

          We are not currently a party to any material legal proceedings.

Employees and Consultants

Employees

          At March 11, 2008, we had 7 full-time employees. We also utilize consultants as well as contract research organizations and other outside specialty firms for various services such as preclinical and clinical trial support, manufacturing, regulatory approval advice and accounting and human resource management. We believe our relationship with our employees is good.

Scientific Advisors and Consultants

          We benefit from consultation with prominent scientists active in fields related to our technology. For this purpose, we have part-time consulting relationships with a number of scientific advisors. At our request, these advisors review the feasibility of product

development programs under consideration, provide advice about advances in areas related to our technology, and aid in recruiting personnel. All of the advisors are employed by academic institutions or other entities and may have commitments to or advisory agreements with other entities that limit their availability to us. Our advisors are required to sign an agreement providing that, if appropriate, they are to disclose and assign to us any ideas, discoveries and inventions they develop in the course of providing consulting services. We also use consultants for various administrative needs. None of our advisors are otherwise affiliated with us.

          In addition to the advisors described above, we have engaged four U.S. contract research organizations to conduct our clinical trials. AAI Pharma, Compleware Corp., inVentiv Clinical Solutions and Pharm-Olam International Ltd., are currently conducting or will conduct our clinical trials in the United States and ex-U.S. for the treatment of anemia associated with uterine fibroids, chronic treatment of uterine fibroids and for the treatment of symptoms associated with endometriosis. In addition, Pharm-Olam International Ltd. is also conducting our current open label safety study with Androxal for the treatment of testosterone deficiency, and inVentiv Clinical Solutions is to assist in the assessment and preparation of the data for resubmission to the FDA. Under our arrangements with these contract research organizations, we design the protocols for the clinical trials and direct the contract research organizations in their efforts. AAI Pharma, inVentiv Clinical Solutions and Pharm-Olam International Ltd., have agreed that we own all of the data associated with the clinical trials.

ITEM 1A. RISK FACTORS

You should carefully consider the risks described below before making an investment decision. You should also refer to the other information in this report, including our financial statements and the related notes incorporated by reference. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. If any of the following risks actually occur, our business, results of operations and financial condition could suffer. In that event the trading price of our common stock could decline, and you may lose all or part of your investment in our common stock. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements.

Risks Relating to Our Business

If we fail to obtain the capital necessary to fund our operations, we will have to delay, reduce or eliminate our research and development programs or commercialization efforts.

          We expect to make additional capital outlays and to increase operating expenditures over the next several years to support our preclinical development and clinical trial activities, particularly with respect to pivotal clinical trials for Proellex and Androxal. We expect our current capital to be sufficient to fund our operations through the third quarter of 2008, depending on the timing and success of our clinical trials. Thereafter we will need to seek additional funding through public or private financings, including equity or debt financings, and/or through other means, including collaborations and license agreements. We do not know whether additional financing will be available when needed, or that, if available, we will obtain financing on terms favorable to our stockholders or us. If adequate funds are not available to us, we may be required to:

	•		delay, reduce the scope of or eliminate one or more of our development programs;
	•		relinquish, license or otherwise dispose of rights to technologies, product candidate or products that we would otherwise seek to develop or commercialize ourselves at an earlier stage or on terms that are less favorable than might otherwise be available; or
	•		liquidate and dissolve our company.

          Our future capital requirements will depend upon a number of factors, including:

	•		the size, complexity, results and timing of our clinical programs;
	•		the cost to obtain sufficient supply of the compounds necessary for our product candidates at a reasonable cost;
	•		the time and cost involved in obtaining regulatory approvals;
	•		the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims; and
	•		competing technological and market developments.

          These factors could result in variations from our currently projected operating and liquidity requirements.

Our product candidates are at an early clinical stage of development, and if we are not able to successfully develop and commercialize them, we may not generate sufficient revenues to continue our business operations.

          We currently have only two product candidates that are in clinical development. We have expended significant time, money and effort in the development of Proellex and Androxal, and we will have to spend considerable additional time, money and effort before seeking regulatory approval to market these product candidates.

          Our business depends primarily on our ability to successfully complete clinical trials, obtain required regulatory approvals and successfully commercialize our product candidates. If we fail to commercialize one or more of our product candidates, we may be unable to generate sufficient revenues to attain profitability or continue our business operations and our reputation in the industry and in the investment community could likely be significantly damaged, each of which would cause our stock price to decline.

Because the data from our preclinical studies and early clinical trials for our product candidates are not necessarily predictive of future results, we can provide no assurances that any of them will have favorable results in clinical trials or receive regulatory approval.
 

          Before we can obtain regulatory approval for the commercial sale of any product candidate that we develop, we are required to complete preclinical development and extensive clinical trials in humans to demonstrate its safety and efficacy. Positive data from preclinical studies or early clinical trials should not be relied upon as evidence that those studies or trials will produce positive results, or that later or larger-scale clinical trials will succeed. Initial clinical trials for Proellex and Androxal have been conducted only in small numbers of patients that may not fully represent the diversity present in larger populations. In addition, these studies have not been subjected to the exacting design requirements typically required by FDA for pivotal trials. Thus the limited data we have obtained may not predict results from studies in larger numbers of patients drawn from more diverse populations, and may not predict the ability of Proellex to treat uterine fibroids, anemia associated with uterine fibroids and endometriosis or Androxal to treat testosterone deficiency and fertility maintenance and symptoms related to AIHH. We will be required to demonstrate through larger-scale clinical trials that these product candidates are safe and effective for use in a diverse population before we can seek regulatory approvals for their commercial sale. There is typically an extremely high rate of attrition from the failure of drug candidates proceeding through clinical trials. We will also be required to complete a two-year rat carcinogenicity study as well as other preclinical studies before we are permitted to file a new drug application, or NDA, for Androxal and Proellex. If Proellex, Androxal, or any other potential future product candidate fails to demonstrate sufficient safety and efficacy in any clinical trial, we would experience potentially significant delays in, or be required to abandon, development of that product candidate. If we delay or abandon our development efforts related to Proellex or Androxal, we may not be able to generate sufficient revenues to continue operations or become profitable.

We have a history of operating losses, and we expect to incur increasing net losses and may not achieve or maintain profitability for some time or at all.

          We have experienced significant operating losses in each fiscal year since our inception. As of December 31, 2007, we had an accumulated deficit of approximately $122.0 million. We expect to continue incurring net losses and we may not achieve or maintain profitability for some time if at all. As we increase expenditures for the clinical development of Proellex and Androxal, we expect our operating losses to increase for at least the next few years. Our ability to achieve profitability will depend, among other things, on successfully completing the development of Proellex and Androxal, obtaining regulatory approvals, establishing marketing, sales and manufacturing capabilities or collaborative arrangements with others that possess such capabilities, and raising sufficient funds to finance our activities. There can be no assurance that we will be able to achieve profitability or that profitability, if achieved, can be sustained.

Raising additional funds by issuing securities or through collaboration and licensing arrangements may cause dilution to existing stockholders, restrict our operations or require us to relinquish proprietary rights.  

          We may raise additional funds through public or private equity offerings, debt financings or corporate collaborations and licensing arrangements. We cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that we raise additional capital by issuing equity securities, our stockholders’ ownership will be diluted. Any debt financing we enter into may involve covenants that restrict our operations. These restrictive covenants may include limitations on borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem capital stock or make investments. In addition, if we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish potentially valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. For example, we might be forced to relinquish all or a portion of our sales and marketing rights with respect to Proellex, Androxal or other potential products or license intellectual property that enables licensees to develop competing products.  

Our stock price could decline significantly based on the results and timing of clinical trials of, and decisions affecting, our product candidates.

          Results of clinical trials and preclinical studies of our current and potential product candidates may not be viewed favorably by us or third parties, including the FDA or other regulatory authorities, investors, analysts and potential collaborators. The same may be true of how we design the clinical trials of our product candidates and regulatory decisions affecting those clinical trials. Biopharmaceutical company stock prices have declined significantly when such results and decisions were unfavorable or perceived negatively or when a product candidate did not otherwise meet expectations. The final results from our clinical development programs may be negative, may not meet expectations or may be perceived negatively. The designs of our clinical trials (which may change significantly and be more expensive than currently anticipated depending on our clinical results and regulatory decisions) may also be viewed negatively by third parties. We may not be successful in completing these clinical trials on our projected timetable, if at all.

          Failure to initiate additional clinical trials or delays in existing clinical trials of Androxal and Proellex or any of our other current or future product candidates, or unfavorable results or decisions or negative perceptions regarding any of such clinical trials, could cause our stock price to decline significantly.

Delays in the commencement of preclinical studies and clinical trials testing of our current and potential product candidates could result in increased costs to us and delay our ability to generate revenues.

          Our product candidates will require continued preclinical studies and extensive clinical trials prior to the submission of a regulatory application for commercial sales. Because of the nature of clinical trials, we do not know whether future planned clinical trials will begin on time, if at all. Delays in the commencement of preclinical studies and clinical trials could significantly increase our product development costs and delay any product commercialization. In addition, many of the factors that may cause, or lead to, a delay in the commencement of clinical trials may also ultimately lead to denial of regulatory approval of a product candidate.

          The commencement of clinical trials can be delayed for a variety of reasons, including delays in:

	•		demonstrating sufficient safety and efficacy in past clinical trials to obtain regulatory approval to commence a further clinical trial;
	•		convincing the FDA that we have selected valid endpoints for use in proposed clinical trials, such as those we recently changed in our Androxal clinical trials after our meeting with the FDA;
	•		reaching agreements on acceptable terms with prospective contract manufacturers for manufacturing sufficient quantities of a product candidate; and
	•		obtaining institutional review board approval to conduct a clinical trial at a prospective site.

In addition, the commencement of clinical trials may be delayed due to insufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease, and the eligibility criteria for the clinical trial.

Delays in the completion of, or the termination of, clinical testing of our current and potential product candidates could result in increased costs to us, and could delay or prevent us from generating revenues.

          Once a clinical trial has begun, it may be delayed, suspended or terminated by us or the FDA, or other regulatory authorities due to a number of factors, including:

	•		lack of effectiveness of any product candidate during clinical trials;
	•		side effects experienced by trial participants or other safety issues;
	•		slower than expected rates of patient recruitment and enrollment or lower than expected patient retention rates;
	•		delays or inability to manufacture or obtain sufficient quantities of materials for use in clinical trials;
	•		Inadequacy of or changes in our manufacturing process or compound formulation;
	•		delays in obtaining regulatory approvals to commence a trial, or “clinical holds” or delays requiring suspension or termination of a trial by a regulatory agency, such as the FDA, after a trial is commenced;
	•		changes in applicable regulatory policies and regulations;
	•		delays in identifying and reaching agreement on acceptable terms with prospective clinical trial sites;
	•		uncertainty regarding proper dosing;
	•		unfavorable results from on-going clinical trials and preclinical studies;
	•		failure of our clinical research organizations to comply with all regulatory and contractual requirements or otherwise fail to perform their services in a timely or acceptable manner;
	•		scheduling conflicts with participating clinicians and clinical institutions;

	•		failure to construct appropriate clinical trial protocols;
	•		insufficient data to support regulatory approval;
	•		inability or unwillingness of medical investigators to follow our clinical protocols;
	•		difficulty in maintaining contact with subjects during or after treatment, which may result in incomplete data;
	•		ongoing discussions with the FDA or other regulatory authorities regarding the scope or design of our clinical trials;
	•		acceptability to the FDA of data obtained from clinical studies conducted in Europe or other non-United States jurisdictions; and
	•		lack of adequate funding to continue clinical trials.

          Many of these factors that may lead to a delay, suspension or termination of clinical testing of a current or potential product candidate may also ultimately lead to denial of regulatory approval of a current or potential product candidate.

          If we experience delays in the completion of, or termination of, clinical testing of any product candidates in the future, our financial results and the commercial prospects for our product candidates will be harmed, and our ability to generate product revenues will be delayed.

Even if we successfully complete clinical trials for Proellex and Androxal, there are no assurances that we will be able to submit, or obtain FDA approval of, a new drug application.

          There can be no assurance that, if our clinical trials for Proellex and Androxal are successfully completed, we will be able to submit a new drug application, or NDA, to the FDA or that any NDA we submit will be approved by the FDA in a timely manner, if at all. After completing clinical trials for a product candidate in humans, a drug dossier is prepared and submitted to the FDA as an NDA, and includes all preclinical studies and clinical trial data relevant to the safety and effectiveness of the product at the suggested dose and duration of use for the proposed indication, in order to allow the FDA to review such drug dossier and to consider a product candidate for approval for commercialization in the United States. If we are unable to submit an NDA with respect to Proellex or Androxal, or if any NDA we submit is not approved by the FDA, we will be unable to commercialize that product. The FDA can and does reject NDAs and requires additional clinical trials, even when drug candidates achieve favorable results in large-scale Phase 3 clinical trials. If we fail to commercialize Proellex or Androxal, we will be unable to generate sufficient revenues to continue operations or attain profitability and our reputation in the industry and in the investment community would likely be damaged.

The results of preclinical studies and completed clinical trials are not necessarily predictive of future results, and our current drug candidates may not have favorable results in later studies or trials.

          Preclinical studies and Phase 1 and Phase 2 clinical trials are not primarily designed to test the efficacy of a drug candidate, but rather to test safety, to study pharmacokinetics and pharmacodynamics, and to understand the drug candidate’s side effects at various doses and schedules. To date, long-term safety and efficacy have not yet been demonstrated in clinical trials for any of our product candidates. Favorable results in our early studies or trials may not be repeated in later studies or trials, including continuing preclinical studies and large-scale clinical trials analyzed with more rigorous statistical methods, and our drug candidates in later-stage trials may fail to show desired safety and efficacy despite having progressed through earlier-stage trials. Unfavorable results from ongoing preclinical studies or clinical trials could result in delays, modifications or abandonment of ongoing or future clinical trials. Clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. Negative or inconclusive results or adverse medical events during a clinical trial could cause a clinical trial to be delayed, repeated or terminated. In addition, we may report top-line data from time to time, which is based on a preliminary analysis of key efficacy and safety data; such data may be subject to change following a more comprehensive review of the data related to the applicable clinical trial.

If commercialized, our product candidates may not be approved for sufficient governmental or third-party reimbursements, which would adversely affect our ability to market our product candidates.

          In the United States and elsewhere, sales of pharmaceutical products depend in significant part on the availability of reimbursement to the consumer from third-party payers, such as government and private insurance plans. Since we have no commercial products, we have not had to face this issue yet; however, third-party payers are increasingly challenging the prices charged for medical products and services. It will be time consuming and expensive for us to go through the process of seeking reimbursement from Medicaid, Medicare and private payers for Proellex and Androxal. Our products may not be considered cost effective, and coverage and reimbursement may not be available or sufficient to allow us to sell our products on a competitive and

profitable basis. The passage of the Medicare Prescription Drug and Modernization Act of 2003 imposes new requirements for the distribution and pricing of prescription drugs which may negatively affect the marketing of our potential products.

If we successfully develop products but those products do not achieve and maintain market acceptance, our business will not be profitable.

          Even if our product candidates are approved for commercial sale by the FDA or other regulatory authorities, the degree of market acceptance of any approved product by physicians, healthcare professionals and third-party payers and our profitability and growth will depend on a number of factors, including:

	•		relative convenience and ease of administration;
	•		the prevalence and severity of any adverse side effects;
	•		availability, effectiveness and cost of alternative treatments;
	•		pricing and cost effectiveness of our drugs;
	•		effectiveness of our or collaborators’ sales and marketing strategies; and
	•		our ability to obtain sufficient third-party insurance coverage or reimbursement.

          If Proellex does not provide a treatment regimen that is more beneficial than Lupron, a GnRH agonist and the current therapeutic standard of care for uterine fibroids, or otherwise provide patient benefit, it likely will not be accepted favorably by the market. Similarly, if Androxal does not provide a treatment regime that is more beneficial than AndroGel, the current standard of care for the treatment of testosterone deficiency, or otherwise provide patient benefit, it likely will not be accepted favorably by the market. If any products we may develop do not achieve market acceptance, then we will not generate sufficient revenue to achieve or maintain profitability.

          In addition, even if our products achieve market acceptance, we may not be able to maintain that market acceptance over time if:

	•		new products or technologies are introduced that are more favorably received than our products, are more cost effective or render our products obsolete;
	•		unforeseen complications arise with respect to use of our products; or
	•		sufficient third-party insurance coverage or reimbursement does not remain available.

We currently rely on third-party manufacturers and other third parties for production of our product candidates, and our dependence on these manufacturers may impair the development of our product candidates.

          Currently, we do not have the ability internally to manufacture the product candidates that we need to conduct our clinical trials. In 2006, we entered into a long-term supply contract with Gedeon Richter for the production of the active pharmaceutical ingredient, or API, for Proellex due to their extensive experience in the manufacture of similar compounds and the cost savings they offered compared to other qualified manufacturers. Pursuant to the terms of this long-term supply contract, we are required, with certain limited exceptions, to purchase all of our future requirements of Proellex from this single supplier for a period of five years after the first sale of Proellex in the United States, to the extent that such supplier is able to satisfy our requirements. The contract may be terminated by either party for failure to remedy a default of any material provision of the contract. Should the contract be terminated for any reason, we would in all likelihood be required to obtain the API from an alternate manufacturer which may increase the costs associated with our clinical trials and result in delays to our clinical trial program for Proellex.

          We have a five year supply agreement with Diagnostic Chemical Limited, doing business as BioVectra, for the supply of the bulk active pharmaceutical ingredient used in Androxal. We have obtained all of our supply of Androxal to date from BioVectra. We have not faced any material problems with BioVectra in supplying us with our necessary quantities of Androxal for our clinical trials and anticipate utilizing them for commercial production if Androxal is approved. There are numerous other suitable manufacturers capable of manufacturing Androxal.

          For the foreseeable future, we expect to continue to rely on third-party manufacturers and other third parties to produce, package and store sufficient quantities of Proellex, Androxal and any future product candidates for use in our clinical trials. These product candidates are complicated and expensive to manufacture. If our third-party manufacturers fail to deliver our product candidates for clinical use on a timely basis, with sufficient quality, and at commercially reasonable prices, we may be required to delay or suspend

clinical trials or otherwise discontinue development and production of our product candidates. While we may be able to identify replacement third-party manufacturers or develop our own manufacturing capabilities for these product candidates, this process would likely cause a delay in the availability of our product candidates and an increase in costs. In addition, third-party manufacturers may have a limited number of facilities in which our product candidates can be produced, and any interruption of the operation of those facilities due to events such as equipment malfunction or failure or damage to the facility by natural disasters could result in the cancellation of shipments, loss of product in the manufacturing process or a shortfall in available product candidates.

Our product candidates have only been manufactured in small quantities to date, and we may face delays or complications in manufacturing quantities of our product candidates in sufficient quantities to meet the demands of late stage clinical trials and marketing.

          We cannot assure that we will be able to successfully increase the manufacturing capacity or scale-up manufacturing volume per batch, whether on our own or in reliance on third-party manufacturers, for any of our product candidates in a timely or economical manner, or at all. To date our product candidates have been manufactured exclusively by third parties in small quantities for preclinical studies and clinical trials. We have arranged for the production of significantly larger quantities of Proellex and Androxal, for future clinical trials but may need to arrange for increased quantities for future commercial sale in the event that such product candidates are approved by the FDA or foreign regulatory bodies. Significant scale-up of manufacturing requires certain additional developmental work, which the FDA must review and approve to assure product comparability. If we or our third-party manufacturers are unable to successfully increase the manufacturing capacity for a product candidate, the regulatory approval or commercial launch of that product candidate may be delayed or there may be a shortage in supply of that product candidate.

Our product candidates require precise, high-quality manufacturing which may not be available at acceptable costs.

          Proellex and Androxal are novel compounds that have never been produced in large scale. As in the development of any new compound, there are underlying risks associated with their manufacture. These risks include, but are not limited to, cost, process scale-up, process reproducibility, construction of a suitable process plant, timely availability of raw materials, as well as regulatory issues associated with the manufacture of an active pharmaceutical agent. Any of these risks may prevent us from successfully developing Proellex or Androxal. Our failure, or the failure of our third-party manufacturers to achieve and maintain these high manufacturing standards, including the incidence of manufacturing errors and reliable product packaging for diverse environmental conditions, could result in patient injury or death, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously hurt our business.

We may experience delays in the development of our product candidates if the third-party manufacturers of our product candidates cannot meet FDA requirements relating to Good Manufacturing Practices.

          Our third-party manufacturers are required to produce our product candidates under FDA current Good Manufacturing Practices in order to meet acceptable standards for our clinical trials. If such standards change, the ability of third-party manufacturers to produce our product candidates on the schedule we require for our clinical trials may be affected. In addition, third-party manufacturers may not perform their obligations under their agreements with us or may discontinue their business before the time required by us to gain approval for or commercialize our product candidates. Any difficulties or delays in the manufacturing and supply of our product candidates could increase our costs or cause us to lose revenue or postpone or cancel clinical trials.

          The FDA also requires that we demonstrate structural and functional comparability between the same drug product produced by different third-party manufacturers. Because we may use multiple sources to manufacture Proellex and Androxal, we may need to conduct comparability studies to assess whether manufacturing changes have affected the product safety, identity, purity or potency of any commercial product candidate compared to the product candidate used in clinical trials. If we are unable to demonstrate comparability, the FDA could require us to conduct additional clinical trials, which would be expensive and significantly delay commercialization of our product candidates.

We rely on third parties to conduct clinical trials for our product candidates, and their failure to timely and properly perform their obligations may result in costs and delays that prevent us from obtaining regulatory approval or successfully commercializing our product candidates.

          We rely on independent contractors, including researchers at clinical research organizations, or CROs, and universities, in certain areas that are particularly relevant to our research and product development plans, such as the conduct of clinical trials. We contracted CROs, to conduct our previous clinical trial with Proellex in Poland for the treatment of uterine fibroids, clinical trial in Bulgaria with Proellex for the treatment of endometriosis and clinical trials with Androxal for the treatment of testosterone deficiency in the United States. We recently hired three CROs to conduct our Pivotal Phase 3 and Open Label Safety clinical trials with Proellex for the treatment of anemia associated with uterine fibroids and chronic treatment of uterine fibroids. In addition, we also hired one of these same CROs to conduct a Phase 2 clinical trial for endometriosis. The competition for these relationships is intense, and we may not

be able to maintain our relationships with them on acceptable terms. Independent contractors generally may terminate their engagements at any time, subject to notice. As a result, we can control their activities only within certain limits, and they will devote only a certain amount of their time conducting research on and trials of our product candidates and assisting in developing them. If they do not successfully carry out their duties under their agreements with us, fail to inform us if these trials fail to comply with clinical trial protocols, or fail to meet expected deadlines, our clinical trials may need to be extended, delayed or terminated. We may not be able to enter into replacement arrangements without undue delays or excessive expenditures. If there are delays in testing or regulatory approvals as a result of the failure to perform by our independent contractors or other outside parties, our drug development costs will increase and we may not be able to attain regulatory approval for or successfully commercialize our product candidates.

Our liability insurance may neither provide adequate coverage nor may it always be available on favorable terms or at all.

          Neither Proellex nor Androxal has been approved for commercial sale. However, the current and future use of our product candidates by us and potential corporate collaborators in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. These claims might be made directly by consumers or healthcare providers or indirectly by pharmaceutical companies, potential corporate collaborators or others selling such products. We may experience financial losses in the future due to product liability claims. We have obtained limited general commercial liability insurance coverage for our clinical trials. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for any of our product candidates. However, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or for liabilities in excess of our insurance limits, our assets may not be sufficient to cover such claims and our business operations could be impaired.

We face significant competition with many companies with substantially greater resources than we have and other possible advantages.

          We are engaged in biopharmaceutical product development, an industry that is characterized by extensive research efforts and rapid technological progress. The biopharmaceutical industry is also highly competitive. Our success will depend on our ability to acquire, develop and commercialize products and our ability to establish and maintain markets for any products for which we receive marketing approval. Potential competitors in North America, Europe and elsewhere include major pharmaceutical companies, specialty pharmaceutical companies and biotechnology firms, universities and other research institutions and government agencies. Many of our competitors have substantially greater research and development and regulatory capabilities and experience, and substantially greater management, manufacturing, distribution, marketing and financial resources, than we do. Accordingly, our competitors may:

	•		develop or license products or other novel technologies that are more effective, safer or less costly than the product candidates that we are developing;
	•		obtain regulatory approval for products before we do; or
	•		commit more resources than we can to developing, marketing and selling competing products.

          The main therapeutic products competitive with Proellex for the treatment of uterine fibroids and endometriosis are GnRH agonists, including Lupron, which is marketed by TAP Pharmaceuticals. There are additional companies developing similar progesterone-blocking technology. Asoprisnil, an anti-progestin being developed by TAP Pharmaceuticals in partnership with Schering AG, has been tested up through Phase 3 clinical trials. TAP Pharmaceuticals is a much larger company than we are with greater resources and greater ability to promote their products than we currently have. In addition, surgical treatment of both uterine fibroids and endometriosis would compete with Proellex, if approved, by removing uterine fibroids and by removing misplaced tissue in women with endometriosis.

          Our main competitors for the treatment of testosterone deficiency are the testosterone replacement therapies currently being marketed. The current standard of care is AndroGel, a topical gel for the replacement of testosterone developed by Solvay Pharmaceuticals. Solvay is a much larger company than we are, with greater resources and marketing ability. Androxal would also compete with other forms of testosterone replacement therapies such as oral treatments, patches, injectables and a tablet applied to the upper gum. There is another topical gel currently marketed by Auxilium Pharmaceuticals called Testim, and a transdermal patch marketed by Watson Pharmaceuticals called AndroDerm. There can be no assurance that our product candidates will be more successful than competitive products. In addition, other potential competitors may be developing testosterone therapies similar to ours.

We are thinly staffed and highly dependent on a limited number of management persons and key personnel, and if we lose these members of our team or are unable to attract and retain additional qualified personnel, our future growth and ability to compete would suffer.

          The competition for qualified personnel in the biopharmaceutical field is intense, and our future success depends upon our ability to attract, retain and motivate highly skilled scientific, technical and managerial employees. We have only seven full-time employees at the present time, including our President and CEO, Joseph S. Podolski, our Vice President, Business Development and CFO, Louis Ploth, Jr. and our Senior Vice President and Chief Medical Officer, Dr. Andre van As. We are highly dependent on Messrs. Podolski and Ploth and Dr. van As for the management of our company and the development of our technologies. Messrs. Podolski and Ploth and Dr. van As have employment agreements with us. There can be no assurance that Mr. Podolski, Mr. Ploth or Dr. van As will remain with us through development of our current product candidates. We do not maintain key person life insurance on any of our directors, officers or employees. The loss of the services of Mr. Podolski, Mr. Ploth or Dr. van As could delay or curtail our research and product development efforts.

Our plan to use collaborations to leverage our capabilities may not be successful.

          As part of our business strategy, we intend to enter into collaboration arrangements with strategic partners to develop and commercialize our product candidates. For our collaboration efforts to be successful, we must identify partners whose competencies complement ours. We must also successfully enter into collaboration agreements with them on terms attractive to us and integrate and coordinate their resources and capabilities with our own. We may be unsuccessful in entering into collaboration agreements with acceptable partners or negotiating favorable terms in these agreements. In addition, we may face a disadvantage in seeking to enter into or negotiating collaborations with potential partners because other potential collaborators may have greater management and financial resources than we do. Also, we may be unsuccessful in integrating the resources or capabilities of these collaborators. In addition, our collaborators may prove difficult to work with or less skilled than we originally expected. If we are unsuccessful in our collaborative efforts, our ability to develop and market product candidates could be severely limited.

Our rights agreement and certain provisions in our charter documents and Delaware law could delay or prevent a change in management or a takeover attempt that you may consider to be in your best interest.

          We have adopted certain anti-takeover provisions, including a rights agreement. The rights agreement will cause substantial dilution to any person who attempts to acquire us in a manner or on terms not approved by our board of directors. We recently amended the rights agreement to permit Efficacy Capital to acquire up to 33% of our outstanding common stock subject to a standstill agreement.

          The rights agreement and certain provisions in our certificate of incorporation and bylaws and under Delaware law could delay or prevent the removal of directors and other management and could make more difficult a merger, tender offer or proxy contest involving us that you may consider to be in your best interest. For example, these provisions:

	•		allow our board of directors to issue preferred stock without stockholder approval;
	•		limit who can call a special meeting of stockholders; and
	•		establish advance notice requirements for nomination for election to the board of directors or for proposing matters to be acted upon at stockholder meetings.

Negative conditions in the global credit markets may impair the liquidity of a portion of our investment portfolio.

A portion of our short-term investments consist primarily of AAA rated taxable auction securities. The recent negative conditions in the global credit markets have prevented some investors from liquidating their holdings of taxable auction securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such securities. If the credit market does not improve, auctions for our invested amounts may continue to fail. If an auction fails for securities in which we have invested, we may be unable to liquidate some or all of our taxable auction securities at par, should we need or desire to access the funds invested in those securities. In the event we need or desire to access these funds, we will not be able to do so until a future auction on these investments is successful or a buyer is found outside the auction process. If a buyer is found but is unwilling to purchase the investments at par, we may incur a loss.

Risks Relating to Our Intellectual Property

We licensed our rights to Proellex from NIH and our inability to fulfill our commitments and obligations under such license may result in forfeiture of our rights.

          Our rights to Proellex are licensed exclusively to us from NIH under a license agreement. This license agreement contains numerous detailed performance obligations, with time sensitive dates for compliance, relating to clinical development and commercialization activities required by us or our designated third-party providers, as well as additional financial milestones and royalties. Failure to achieve the benchmarks specified in the commercial development plan attached to the license agreement or meet payment obligations could result in termination of the license agreement and the loss of our rights to develop and commercialize Proellex. We periodically update the commercial development plan as such plans evolve. There can be no assurance that we will be able to meet any or all of the performance objectives in the future on a timely basis or at all, or that, if we fail to meet any of such objectives, NIH will agree to revised objectives. NIH has the ability to terminate the agreement for an uncured material breach of the agreement, if we made a false statement or willful omission in our license application, if we do not keep Proellex reasonably available to the public after commercial launch, if we cannot reasonably satisfy unmet health and safety needs, or if we cannot reasonably justify a failure to comply with the domestic production requirement unless such requirement has been waived.

There is a third party individual patent holder that claims priority over our patent application for Androxal.

          A third party individual holds two issued patents related to the use of an anti-estrogen such as clomiphene citrate and others for use in the treatment of androgen deficiency and disorders related thereto. In our prior filings with the SEC, we have described our request to the U.S. Patent and Trademark Office, or PTO, for re-examination of one of these patents based on prior art. The third party amended the claims in the reexamination proceedings, which led the PTO to determine that the amended claims are patentable in view of those publications under consideration and a reexamination certificate was issued. However, we believe that the amended claims are invalid based on additional prior art publications, and our request for reexamination by the PTO in light of a number of these additional publications and other publications cited by the PTO, has been granted. In November, 2007, the PTO issued a final Office action, rejecting all of the claims. In January, 2008, the patent holder responded to the final Office action. In February, 2008, the PTO issued an Advisory Action stating that the patent holder’s response failed to overcome the rejections. The patent holder has filed a Notice of Appeal. We also believe that the second of these two patents is invalid in view of published prior art not considered by the PTO. Nevertheless, there is no assurance that either patent will ultimately be found invalid over the prior art. If such patents are not invalidated by the PTO we may be required to obtain a license from the holder of such patents in order to develop Androxal further or attempts may be made to undertake further legal action to invalidate such patents. If such licenses were not available on acceptable terms or at all, we may not be able to successfully commercialize Androxal.

We cannot assure that our manufacture, use or sale of our product candidates will not infringe on the patent rights of others.

          There can be no assurance that the manufacture, use or sale of any of our product candidates will not infringe the patent rights of others. We may be unable to avoid infringement of the patent rights of others and may be required to seek a license, defend an infringement action or challenge the validity of the patents in court. There can be no assurance that a license to the allegedly infringed patents will be available to us on terms and conditions acceptable to us, if at all, or that we will prevail in any patent litigation. Patent litigation is extremely costly and time-consuming, and there can be no assurance that we will have sufficient resources to defend any possible litigation related to such infringement. If we do not obtain a license on acceptable terms under such patents, or are found liable for infringement, or are not able to have such patents declared invalid, we may be liable for significant money damages, may encounter significant delays in bringing our product candidates to market, or may be precluded from participating in the manufacture, use or sale of any such product candidates, any of which would materially and adversely affect our business.

A dispute regarding the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be costly and result in delays in our research and development activities.

          Our commercial success also depends upon our ability to develop and manufacture our product candidates and market and sell drugs, if any, and conduct our research and development activities without infringing or misappropriating the proprietary rights of others. We may be exposed to future litigation by others based on claims that our product candidates, technologies or activities infringe the intellectual property rights of others. Numerous United States and foreign issued patents and pending patent applications owned by others also exist in the therapeutic areas in, and for the therapeutic targets for, which we are developing drugs. These could materially affect our ability to develop our product candidates or sell drugs, and our activities, or those of our licensor or future collaborators, could be determined to infringe these patents. Because patent applications can take many years to issue, there may be currently pending applications, unknown to us, which may later result in issued patents that our drug candidates or technologies may infringe. There also may be existing patents, of which we are not aware, that our product candidates or technologies may infringe. Further, there may be issued patents and pending patent applications in fields relevant to our business, of which we are or may become aware, that we believe we do not infringe or that we believe are invalid or relate to immaterial portions of our overall drug discovery and development efforts.

We cannot assure you that others holding any of these patents or patent applications will not assert infringement claims against us for damages or seeking to enjoin our activities. We also cannot assure you that, in the event of litigation, we will be able to successfully assert any belief we may have as to non-infringement, invalidity or immateriality, or that any infringement claims will be resolved in our favor.

          In addition, others may infringe or misappropriate our proprietary rights, and we may have to institute costly legal action to protect our intellectual property rights. We may not be able to afford the costs of enforcing or defending our intellectual property rights against others. There could also be significant litigation and other administrative proceedings in our industry that affect us regarding patent and other intellectual property rights. Any legal action or administrative action against us, or our collaborators, claiming damages or seeking to enjoin commercial activities relating to our drug discovery and development programs could:

	•		require us, or potential collaborators, to obtain a license to continue to use, manufacture or market the affected drugs, methods or processes, which may not be available on commercially reasonable terms, if at all;
	•		prevent us from importing, making, using, selling or offering to sell the subject matter claimed in patents held by others and subject to potential liability for damages; or
	•		consume a substantial portion of our managerial, scientific and financial resources; or be costly, regardless of the outcome.

          Furthermore, because of the substantial amount of pre-trial documents and witness discovery required in connection with intellectual property litigation, there is risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the trading price of our common stock.

We face substantial uncertainty in our ability to protect our patents and proprietary technology.

          Our ability to commercialize our products will depend, in part, on our or our licensor’s ability to obtain patents, to enforce those patents and preserve trade secrets, and to operate without infringing on the proprietary rights of others. The patent positions of biopharmaceutical companies are highly uncertain and involve complex legal and factual questions. There can be no assurance that:

	•		Patent applications for and relating to our products, Proellex and Androxal, will result in issued patents;
	•		Patent protection will be secured for any particular technology;
	•		Any patents that have been or may be issued to us, such as our pending patent applications relating to Proellex or Androxal, or any patents that have been or may be issued to our licensor, such as the patent(s) and application(s) underlying our Proellex compound, when issued, will be valid and enforceable;
	•		any patents will provide meaningful protection to us;
	•		others will not be able to design around the patents; or
	•		our patents will provide a competitive advantage or have commercial application.

          The failure to obtain and maintain adequate patent protection would have a material adverse effect on us and may adversely affect our ability to enter into, or affect the terms of, any arrangement for the marketing of any product.

We cannot assure that our patents will not be challenged by others.

          There can be no assurance that patents owned by or licensed to us will not be challenged by others. We could incur substantial costs in proceedings, including interference proceedings before the PTO and comparable proceedings before similar agencies in other countries in connection with any claims that may arise in the future. These proceedings could result in adverse decisions about the patentability of our or our licensor’s inventions and products, as well as about the enforceability, validity or scope of protection afforded by the patents. Any adverse decisions about the patentability of our product candidates could cause us to either lose rights to develop and commercialize our product candidates or to license such rights at substantial cost to us. In addition, even if we were successful in such proceedings, the cost and delay of such proceedings would most likely have a material adverse effect on our business.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information, may not adequately protect our intellectual property, and will not prevent third parties from independently discovering technology similar to or in competition with our intellectual property.

          We rely on trade secrets and other unpatented proprietary information in our product development activities. To the extent we rely on trade secrets and unpatented know-how to maintain our competitive technological position, there can be no assurance that others may not independently develop the same or similar technologies. We seek to protect trade secrets and proprietary knowledge, in part, through confidentiality agreements with our employees, consultants, advisors, collaborators and contractors. Nevertheless, these agreements may not effectively prevent disclosure of our confidential information and may not provide us with an adequate remedy in the event of unauthorized disclosure of such information. If our employees, scientific consultants, advisors, collaborators or contractors develop inventions or processes independently that may be applicable to our technologies, product candidates or products, disputes may arise about ownership of proprietary rights to those inventions and processes. Such inventions and processes will not necessarily become our property, but may remain the property of those persons or their employers. Protracted and costly litigation could be necessary to enforce and determine the scope of our proprietary rights. If we fail to obtain or maintain trade secret protection for any reason, the competition we face could increase, reducing our potential revenues and adversely affecting our ability to attain or maintain profitability.

We cannot protect our intellectual property rights throughout the world.

          Filing, prosecuting, and defending patents on all of our drug discovery technologies and all of our potential drug candidates throughout the world would be prohibitively expensive. Competitors may use our technologies to develop their own drugs in jurisdictions where we have not obtained patent protection. These drugs may compete with our drugs, if any, and may not be covered by any of our patent claims or other intellectual property rights. The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States, and many companies have encountered significant problems in protecting and defending such rights in foreign jurisdictions. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, the patent owner has failed to “work” the invention in that country or the third party has patented improvements). In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the patent. Compulsory licensing of life-saving drugs is also becoming increasingly popular in developing countries either through direct legislation or international initiatives. Such compulsory licenses could be extended to include some of our drug candidates, which could limit our potential revenue opportunities. Moreover, the legal systems of certain countries, particularly certain developing countries, do not favor the aggressive enforcement of patents and other intellectual property protection, particularly those relating to biotechnology and/or pharmaceuticals, which makes it difficult for us to stop the infringement of our patents. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

Dividends

          We have never paid dividends on our common stock. We currently intend to retain earnings, if any, to support the development of our business and do not anticipate paying dividends in the foreseeable future. Payment of future dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs and plans for expansion.

Rights Plan

          We are party to a rights agreement, as amended, pursuant to which a dividend consisting of one preferred stock purchase right was distributed for each share of our common stock held as of the close of business on September 13, 1999, and to each share of common stock issued thereafter until the earlier of (i) the distribution date which is defined in the rights plan, (ii) the redemption date which is defined in the rights plan or (iii) September 13, 2010. The rights plan is designed to deter coercive takeover tactics and to prevent an acquirer from gaining control of us without offering fair value to our stockholders. The rights will expire on September 13, 2010, subject to earlier redemption or exchange as provided in the rights plan. Each right entitles its holder to purchase from us one one-hundredth of a share of a new series of Series One Junior Participating Preferred Stock at a price of $20.00 per one one-hundredth of a share, subject to adjustment. The rights are generally exercisable only if a person acquires beneficial ownership of 20 percent or more of our outstanding common stock.

          A complete description of the rights, the rights plan with Computershare Trust Company, N.A., as rights agent, and the Series One Junior Participating Preferred Stock is hereby incorporated by reference from the information appearing under the caption “Item 1. Description of the Registrant’s Securities to be Registered” contained in the Registration Statement on Form 8-A filed on September 3, 1999, and as amended by amendments to such Registration Statement on Form 8-A/A filed on September 11, 2002, October 31, 2002, June 30, 2005 and January 10, 2008.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following management’s discussion and analysis should be read in conjunction with our historical consolidated financial statements and their notes included elsewhere in this Form 10-K. This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, such as those set forth under “Risk Factors” and elsewhere in this Form 10-K.

Overview

     Repros Therapeutics Inc. (“the Company”, “RPRX,” or “we,” “us” or “our”), was organized on August 28, 1987. We are a development stage biopharmaceutical company focused on the development of oral small molecule drugs for major unmet medical needs. We have a proven track-record of efficient and rapid advancement of our therapeutic candidates through clinical development.

     Our current product pipeline includes:

     Proellex

	•		Phase 3 for the treatment of anemia associated with uterine fibroids
	•		Phase 3 for the chronic treatment of uterine fibroids
	•		Phase 2 for the treatment of endometriosis

     Androxal

	•		Planned Phase 2b trial to treat men with AIHH, with concomitant plasma glucose and lipid elevations
	•		Planned Phase 2b trial in men with low testosterone levels wanting to improve or maintain their fertility and/or sperm function

     Our lead drug, Proellex^®, is a selective blocker of the progesterone receptor and is being developed for the treatment of uterine fibroids, anemia associated with excessive menstrual bleeding relating to uterine fibroids, or anemia associated with uterine fibroids, and endometriosis. During the first quarter of 2008 we filed an Investigational New Drug Application, or IND, for Proellex for the new indication of anemia associated with uterine fibroids. During the first quarter of 2008 we also initiated two 65 patient registration Phase 3 pivotal clinical trials with Proellex for this new indication, which will be conducted in approximately 15-20 sites in the United States and in several sites outside the United States. Our goal is to file a New Drug Application, or NDA, for this indication around year end 2008. During the first quarter of 2008 we also initiated two registration Phase 3 pivotal clinical trials with Proellex for the chronic treatment of uterine fibroids and two Open Label Safety Studies. We are also currently conducting a Phase 2 clinical trial with Proellex for the treatment of endometriosis.

     Uterine fibroids, anemia associated with uterine fibroids and endometriosis affect a significant number of women of childbearing age in the developed world. There is no currently-approved effective long-term drug treatment for uterine fibroids or endometriosis. In the United States alone, 300,000 women per year undergo a hysterectomy as a result of severe uterine fibroids.

     Our second product candidate, Androxal^®, is a single isomer of clomiphene citrate and is an orally active proprietary small molecule compound. We intend to initiate two proof-of-concept Phase 2b clinical trials with Androxal in the second quarter of 2008. One of these clinical trials will be in men with adult-onset idiopathic hypogonadotrophic hypogonadism, or AIHH, with concomitant plasma glucose and lipid elevations, all of which are components of Metabolic Syndrome. Recent published studies in older men show a link of low testosterone with higher incidences of insulin resistance, diabetes and consequently mortality rates. Based on a retrospective review of our recently completed six-month clinical trial with Androxal for the treatment of low testosterone due to secondary hypogonadism, our findings showed that Androxal therapy resulted in a significant reduction in mean glucose levels in men with a body mass index, or BMI, >26 and glucose levels >104 md/dL, an outcome not seen in the placebo or AndroGel^® arms of this study. AndroGel is the current leading therapy for testosterone replacement. The second Phase 2b Androxal clinical trial will be in men of reproductive age with low testosterone levels who want to improve or maintain their fertility and/or sperm function while being treated for low testosterone. We believe Androxal will be superior to the existing drugs used to normalize testosterone as only Androxal has the property of restoring both luteinizing hormone, or LH, and follicle stimulating hormone, or FSH, levels. LH and FSH are the pituitary hormones that stimulate testicular testosterone and sperm production, respectively. According to the Urology Channel, recent estimates show that approximately 13 million men in the United States experience testosterone deficiency.

     We were previously developing Androxal in the United States to treat testosterone deficiency due to secondary hypogonadism by restoring normal testosterone production in males with functional testes and diminished pituitary function, a common condition in the aging male. Based on a Type “C” meeting held with the Food and Drug Administration, or FDA, on October 15, 2007 we believe we do not have a clear clinical path to develop Androxal for this indication in the U.S. at this time. Although we believe Androxal could be developed outside of the U.S., due to the limited European market for this indication and our limited internal resources we do not intend to pursue approval outside of the U.S. at this time.

     We also continue to maintain our patent portfolio of our phentolamine-based products for the treatment of sexual dysfunction. We continue to try to create value from these assets in various ways which includes product out-licensing.

     On February 5, 2007, we completed a public offering of 2,610,000 shares of our common stock at a purchase price of $13.75 per share. As a result of the offering, we received approximately $33.1 million in net proceeds which we have used and intend to continue to use for the clinical development of Proellex and Androxal.

     The clinical development of pharmaceutical products is a complex undertaking, and many products that begin the clinical development process do not obtain regulatory approval. The costs associated with our clinical trials may be impacted by a number of internal and external factors, including the number and complexity of clinical trials necessary to obtain regulatory approval, the number of eligible patients necessary to complete our clinical trials and any difficulty in enrolling these patients, and the length of time to complete our clinical trials. Given the uncertainty of these potential costs, we recognize that the total costs we will incur for the clinical development of our product candidates may exceed our current estimates. We do, however, expect these costs to increase substantially in future periods as we continue later-stage clinical trials, initiate new clinical trials for additional indications and seek to obtain regulatory approvals. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could cause our research and development expenditures to increase and, in turn, have a material adverse effect on our results of operations.

     We have not generated any substantial revenue from commercial sale of our current product candidates. We will not receive any revenue from commercial sales unless we, or a potential partner, complete the clinical trial process, obtain regulatory approval, and successfully commercialize one or more of our product candidates. We cannot be certain when or if any of our current product candidates will ever generate cash flow.

     As of December 31, 2007, the Company had accumulated losses of $122.0 million and had cash, cash equivalents and marketable securities of $25.9 million. We have experienced negative cash flows from operations since inception and have funded our activities to date primarily from equity financings and corporate collaborations. Based on our current planned clinical programs, we will need to raise additional capital by the fourth quarter of 2008. We believe we can secure additional cash resources through either the out-licensing of Proellex or through the sale of our equity securities. We have prior experience under similar situations as the current situation, in raising funds from corporate alliances as well as equity financings. Our preference is to complete an appropriate licensing deal with Proellex which we feel would be the least dilutive to our existing shareholders.

     We believe that we will secure sufficient capital to continue our currently planned clinical programs without any significant delay or impact on such programs, assuming that the results of our current ongoing Open Label Safety Trial with Proellex for the treatment of uterine fibroids and our U.S. Phase 2 clinical trial with Proellex for the treatment of endometriosis are favorable. If the results of these trials are unfavorable, there can be no assurance that the Company will be successful in obtaining additional capital in amounts sufficient to continue to fund its operations through either the out-licensing of Proellex, the sale of equity securities, or other alternative sources of funding, which outcome would have a material adverse effect on the Company. Therefore, there is substantial doubt about our ability to continue as a going concern for a reasonable period of time.

     It is possible that our current clinical trial activities will be more costly and take longer than we anticipate; accordingly, there can be no assurance that additional capital will not be necessary prior to the time anticipated.

     Our common stock is traded on the NASDAQ Global Market under our ticker symbol, RPRX. Effective January 8, 2007, we voluntarily withdrew the listing of our common stock from NYSE Arca, Inc., formerly the Pacific Exchange, in order to streamline administrative requirements and reduce expenses.

     We are an accelerated filer and are subject to additional financial regulatory requirements, including Section 404 of Sarbanes-Oxley, which requires us to include in this annual report a report by management on our internal control over financial reporting and an accompanying auditor’s report. These additional activities have resulted in increased costs to us and will result in future increased costs as we maintain compliance with these requirements.

     We have 7 full-time employees who utilize the services of contract research organizations, contract manufacturers and various consultants to assist us in performing clinical and regulatory services for the clinical development of our products. We are substantially dependent on our various contract groups to adequately perform the activities required to obtain regulatory approval of our products.

     Our results of operations may vary significantly from year to year and quarter to quarter, and depend, among other factors, on our ability to be successful in our clinical trials, the regulatory approval process in the United States and other foreign jurisdictions and the ability to complete new licenses and product development agreements. The timing of our revenues may not match the timing of our associated product development expenses. To date, research and development expenses have generally exceeded revenue in any particular period and/or fiscal year.

     We had an accumulated deficit of $122.0 million as of December 31, 2007. The value of the tax asset associated with this accumulated deficit can be substantially diminished in value to us due to various tax regulations, including change in control provisions in the tax code. For additional information relating to our net operating loss carryforward, see “Note 6. Federal Income Taxes” of the Notes to Consolidated Financial Statements. Losses have resulted principally from costs incurred in conducting clinical trials for our product candidates, in research and development activities related to efforts to develop our products and from the associated administrative costs required to support those efforts. There can be no assurance that we will be able to successfully complete the transition from a development stage company to the successful introduction of commercially viable products. Our ability to achieve profitability will depend, among other things, on successfully completing the clinical development of our products in a reasonable time frame and at a reasonable cost, obtaining regulatory approvals, establishing marketing, sales and manufacturing capabilities or collaborative arrangements with others that possess such capabilities, our and our partners’ ability to realize value from our research and development programs through the commercialization of those products and raising sufficient funds to finance our activities. There can be no assurance that we will be able to achieve profitability or that profitability, if achieved, can be sustained. See “Item 1. Business — Risk Factors” and “Note 1. Organization and Operations” of Notes to Consolidated Financial Statements.

Critical Accounting Policies and the Use of Estimates

     The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Please see Note 2, “Summary of Significant Accounting Policies”, for a detailed discussion of our critical accounting policies. A brief summary of our accounting policies is provided below.

Investments-Trading Securities

     Management determines the appropriate classification of investments in debt and equity securities at the time of purchase and re-evaluates such designation as of each subsequent balance sheet date. Securities for which we have the ability and intent to hold to maturity are classified as “held to maturity”. Securities classified as “trading securities” are recorded at fair value. Gains and losses on trading securities, realized and unrealized, are included in earnings and are calculated using the specific identification method. Any other securities are classified as “available for sale.” At December 31, 2007 all securities were classified as trading securities.

     Our investments typically include corporate bonds and notes, Euro-dollar bonds, taxable auction securities and asset-backed securities. Our policy is to require minimum credit ratings of A2/A and A1/P1 with maturities of up to three years, excluding taxable auction securities. These securities are classified as trading securities and are valued in our financial statements at their fair value. The average life of the investment portfolio, excluding taxable auction securities, may not exceed 24 months.

Capitalized Patent Costs

     We capitalize the cost associated with building our patent library for Proellex and Androxal. As of December 31, 2007, other assets consist of capitalized patent costs in the amount of $1,170,000. Patent costs, which include legal and application costs related to the patent portfolio, are being amortized over 20 years, or the lesser of the legal or the estimated economic life of the patent. Amortization of patent costs was $10,350, $71 and zero in 2007, 2006 and 2005, respectively. Of the $1,170,000 in capitalized patents, $460,000 related to patents for Proellex and $710,000 related to Androxal.

R&D Expense

     Research and development, or R&D, expenses include salaries and related employee expenses, contracted regulatory affairs activities, insurance coverage for clinical trials and prior product sales, contracted research and consulting fees, facility costs and internal research and development supplies. We expense research and development costs in the period they are incurred. These costs consist of direct and indirect costs associated with specific projects as well as fees paid to various entities that perform research on our behalf.

Stock-Based Compensation

     We have two stock-based compensation plans at December 31, 2007, the 2000 Non-Employee Directors’ Stock Option Plan, or 2000 Director Plan and the 2004 Stock Option Plan, or 2004 Plan. We account for our stock-based compensation plans under FASB Statement No. 123(R), “Share-Based Payments” (“SFAS 123(R)”). SFAS 123(R) generally requires the recognition of the cost of employee services for share-based compensation based on the grant date fair value of the equity or liability instruments issued. Under

SFAS 123(R), we used the Black-Scholes option pricing model to estimate the fair value of our stock options. We follow the expanded guidance in SFAS 123(R) for the development of our assumptions used as inputs to the Black-Scholes model. Expected volatility is determined using historical volatilities based on historical stock prices for a period equal to the expected term. The expected volatility assumption is adjusted if future volatility is expected to vary from historical experience. The expected term of options represents the period of time that options granted are expected to be outstanding and falls between the options’ vesting and contractual expiration dates. The risk-free interest rate is based on the yield at the date of grant of a zero-coupon U.S. Treasury bond whose maturity period equals the option’s expected term.

Income Tax Estimates and Patents

     Actual results could differ materially from our estimates. The items in our financial statements requiring significant estimates and judgments are as follows:

	•		We have had losses since inception and, therefore, have not been subject to federal income taxes. We have accumulated approximately $2.7 million of research and development tax credits. As of December 31, 2007, we had approximately $107.9 million of net operating loss, or NOL, carry-forwards for federal income tax purposes. Additionally, approximately $1.5 million of NOLs, and approximately $64,000 of research and development tax credits, expired in 2007. Under SFAS No. 109, “Accounting for Income Taxes,” an NOL requires the recognition of a deferred tax asset. However, a valuation allowance must be recorded for deferred tax assets whose recovery is deemed unlikely. As we have incurred losses since inception, and there is no certainty of future revenues, our deferred tax assets have been reserved in full in the accompanying consolidated financial statements.
	•		We review for the impairment of capitalized patent costs whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows expected to result from the patent are less than its carrying amount. The impairment loss recognized represents the excess of the patent cost as compared to its estimated fair value. We have determined that our capitalized patent costs are not impaired as of December 31, 2007.

RECENT ACCOUNTING PRONOUNCEMENTS

     In September 2006, FASB issued SFAS No. 157, “Fair Value Measurements’” which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. This Statement is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. In February 2008, the FASB issued a Staff Position that will (1) partially defer the effective date of SFAS 157 for one year for certain nonfinancial assets and nonfinancial liabilities and (2) remove certain leasing transactions from the scope of SFAS 157. On November 14, 2007, the FASB agreed to a one-year deferral for the implementation of SFAS 157 for other non-financial assets and liabilities. Earlier application is encouraged provided that the reporting entity has not yet issued financial statements for that fiscal year including financial statements for an interim period within that fiscal year. We are assessing SFAS No. 157 and have not determined yet the impact that the adoption of SFAS No. 157 will have on our results of operations or financial position.

     In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an Amendment of FASB Statement No. 115.” This pronouncement permits entities to use the fair value method to measure certain financial assets and liabilities by electing an irrevocable option to use the fair value method at specified election dates. After election of the option, subsequent changes in fair value would result in the recognition of unrealized gains or losses as period costs during the period the change occurred. SFAS No. 159 becomes effective as of the beginning of the first fiscal year that begins after November 15, 2007, with early adoption permitted. However, entities may not retroactively apply the provisions of SFAS No. 159 to fiscal years preceding the date of adoption. We are currently evaluating the impact that SFAS No. 159 may have on our financial position, results of operations and cash flows.

     In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations” (“SFAS 141R”), which replaces SFAS 141, “Business Combinations.” SFAS 141R retains the fundamental requirements in Statement 141 that the purchase method of accounting be used for all business combinations. This statement further establishes principals and requirements for how the acquiring entity recognizes and measures in its financial statements the identifiable assets acquired, including goodwill, the liabilities assumed, and any noncontrolling interest in the acquiree. SFAS 141R also determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS 141R applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008, and the Company cannot estimate any impact this statement may have on the Company’s results of operations or financial position as any potential business combinations after the implementation date are unknown.

     In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51” (“SFAS 160”). SFAS 160 addresses the accounting and reporting for entities that consolidate a

noncontrolling interest, sometimes called a minority interest. SFAS 160 is effective for fiscal years beginning after December 15, 2008, but is not expected to have any impact on the Company’s consolidated financial statements as the Company does not currently consolidate any noncontrolling interest entities.

Results of Operations

Comparison of Years Ended December 31, 2007 and 2006

     Revenues. Total revenues for 2007 increased 153% to $1.5 million as compared to $596,000 for 2006.

     Interest income increased 153% to $1.5 million for 2007 as compared to $596,000 for 2006. The increase in interest income is primarily due to an increase in marketable securities as a result of the completion of our public offering on February 5, 2007 in which we received approximately $33.1 million in net proceeds.

     Research and Development Expenses. R&D expenses include contracted research, regulatory affairs activities and general research and development expenses. R&D expenses increased 4% to $12.4 million in 2007 as compared to $11.9 million in 2006. The increased expenses for 2007 are primarily due to an increase in our clinical and preclinical activities of $406,000, an increase of $312,000 in consulting fees, an increase of $243,000 in personnel costs, and an increase in non-cash stock option compensation expense of $127,000, partially offset by a decrease in manufacturing activities of $646,000.

     General and Administrative Expenses. G&A expenses decreased 3% to $2.8 million for 2007 as compared to $2.9 million for 2006. The decrease in expenses is primarily due to a decrease of $156,000 in professional services.

Comparison of Years Ended December 31, 2006 and 2005

     Revenues. Total revenues for 2006 decreased 6% to $596,000 as compared to $634,000 for 2005. Research and development grants for 2006 were zero as compared to $4,000 for 2005 which was the remaining amount under our Small Business Innovative Research, or SBIR, grants.

     Interest income decreased 5% to $596,000 for 2006 as compared to $630,000 for 2005. The decrease in interest income is primarily due to lower cash balances.

     Research and Development Expenses. R&D expenses include contracted research, regulatory affairs activities and general research and development expenses. R&D expenses increased 95% to $11.9 million in 2006 as compared to $6.1 million in 2005. The increased expenses for 2006 are primarily due to increased spending in our clinical development programs ($3.5 million for Proellex and $2.1 million for Androxal), an increase of $142,000 in personnel costs, an increase in non-cash stock option compensation expense of $107,000 and a $71,000 increase in consulting fees.

     General and Administrative Expenses. G&A expenses increased 50% to $2.9 million for 2006 as compared to $1.9 million for 2005. The increase in expenses is primarily due to an increase of $593,000 in non-cash stock option compensation expense, an increase of $184,000 in professional services and an increase of $66,000 in costs associated with meeting the requirements of Section 404 of the Sarbanes-Oxley Act.

Off-Balance Sheet Arrangements

     As of December 31, 2007, we did not have any off-balance sheet arrangements.

Liquidity and Capital Resources

     Since our inception, we have financed our operations primarily with proceeds from private placements and public offerings of equity securities and with funds received under collaborative agreements. We completed a public offering on February 5, 2007 of 2,610,000 shares of our common stock at a purchase price of $13.75 per share resulting in net proceeds to us of approximately $33.1 million. In February 2005, we completed a public offering of 5,060,000 shares of our common stock for net proceeds of approximately $18.1 million.

     Our primary use of cash to date has been in operating activities to fund research and development, including preclinical studies and clinical trials, and general and administrative expenses. We had cash, cash equivalents and marketable securities of approximately $25.9 million as of December 31, 2007 as compared to $6.7 million as of December 31, 2006. The increase in cash balance as of December 31, 2007 as compared to December 31, 2006 is primarily due to the completion of our follow-on public offering of 2,610,000 shares on February 5, 2007 in which we received approximately $33.1 million in net proceeds.

     Excluding maturities and purchases of marketable securities, net cash of approximately $13.6 million, $10.1 million, and $7.4 million was used in operating activities during 2007, 2006, and 2005, respectively. The major uses of cash for operating activities during 2007 was to fund our clinical development programs and associated administrative costs, net of interest income, of $13.7 million. Cash used in investing activities was $363,000 in 2007 primarily for investments in technology rights related to our Proellex and Androxal patent portfolios. Cash provided by financing activities in 2007 was approximately $33.1 million relating to the follow-on public offering of 2,610,000 shares on February 5, 2007 and the exercise of 13,942 stock options.

     The Company leases laboratory and office space, and equipment pursuant to leases accounted for as operating leases. The lease for the Company’s laboratory and office space expires in June 2010. Rental expense for the years ended December 31, 2007, 2006 and 2005, was approximately $63,000, $53,000 and $39,000, respectively. Future minimum lease payments under non-cancelable leases with original terms in excess of one year as of December 31, 2007, are as follows (in thousands):

2008		$	60
2009			60
2010			30
Total		$	150

     We have had losses since inception and, therefore, have not been subject to federal income taxes. We have accumulated approximately $2.7 million of research and development tax credits. As of December 31, 2007 we had approximately $107.9 million of NOLs for federal income tax purposes. Additionally, approximately $1.5 million of NOLs, and approximately $64,000 of research and development tax credits expired in the year 2007. Due to various tax regulations, including change in control provisions in the tax code the value of this tax asset to us can be substantially diminished. For additional information relating to our NOLs, see “Note 6. Federal Income Taxes” of the Notes to Consolidated Financial Statements.

     We have experienced negative cash flows from operations since inception and have funded our activities to date primarily from equity financings and corporate collaborations. We will require substantial funds for research and development, including preclinical studies and clinical trials of our product candidates, and to commence sales and marketing efforts if appropriate, if the FDA or other regulatory approvals are obtained. We believe that our existing capital resources under our current operating plan will be sufficient to fund our operations through at least September 30, 2008. There can be no assurance that changes in our current strategic plans or other events will not result in accelerated or unexpected expenditures.

     Our capital requirements will depend on many factors, including the costs and timing of seeking regulatory approvals of our products; the problems, delays, expenses and complications frequently encountered by development stage companies; the progress of our preclinical and clinical activities; the costs associated with any future collaborative research, manufacturing, marketing or other funding arrangements; our ability to obtain regulatory approvals; the success of our potential future sales and marketing programs; the cost of filing, prosecuting and defending and enforcing any patent claims and other intellectual property rights; changes in economic, regulatory or competitive conditions of our planned business; and additional costs associated with being a publicly-traded company. Estimates about the adequacy of funding for our activities are based on certain assumptions, including the assumption that our cash, cash equivalents and investments will be sold at their current fair values ($25.9 million) before September 30, 2008; that the development and regulatory approval of our products can be completed at projected costs; and that product approvals and introductions will be timely and successful. There can be no assurance that changes in our research and development plans, acquisitions or other events will not result in accelerated or unexpected expenditures. To satisfy our capital requirements, we may seek to raise additional funds in the public or private capital markets. We may seek additional funding through corporate collaborations and other financing vehicles. There can be no assurance that any such funding will be available to us on favorable terms or at all. If we are successful in obtaining additional financing, the terms of such financing may have the effect of diluting or adversely affecting the holdings or the rights of holders of our common stock. Because of the above factors, there is substantial doubt about our ability to continue as a going concern for a reasonable period of time.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Interest Rate Risk. Cash, cash equivalents and investments were approximately $25.9 million at December 31, 2007. These assets were primarily invested in investment grade corporate bonds and commercial paper with maturities of less than 18 months, which are classified as Trading Securities. We do not invest in derivative securities. Although our portfolio is subject to fluctuations in interest rates and market conditions, no significant gain or loss on any security is expected to be recognized in earnings due to the expected short holding period.

     The Company held $6.4 million in taxable auction securities at December 31, 2007.  Since December 31, 2007 the Company has sold, or has received a call for mandatory redemption of, its position in all taxable auction securities except for two securities, which are valued at $2 million in the accompanying financial statements.  While each security had successful auctions subsequent to year end, in February 2008 auctions for both of these securities failed.  As a result of the failed auctions, the Company will contractually receive a

higher interest rate (30 day libor + 1.25%, and 30 day libor multiplied by 250%, respectively) during the related 28 day auction period.  The Company expects that it will be able to liquidate its position in these securities at par ($2 million total) through a sale of the securities in future auctions or through the redemption of the securities by the counterparty within twelve months of December 31, 2007.  Accordingly, the Company has classified these securities as current assets. Each of the two remaining taxable auction securities carry AAA ratings.  The Company will continue to monitor the value and classification of its taxable auction securities each reporting period for a possible impairment if a decline in fair value occurs.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

     We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed with the Securities and Exchange Commission, or SEC, pursuant to the Securities Exchange Act of 1934, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Commission and that such information is accumulated and communicated to our management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), as appropriate, to allow timely decisions regarding required disclosures.

     Management, with the participation of our CEO and CFO, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our CEO and CFO have each concluded that as of the end of such period, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

Management’s Report on Internal Control Over Financial Reporting

     Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

     Management evaluated the effectiveness of internal control over financial reporting based on the criteria in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

     Based on management’s evaluation, management has concluded that internal control over financial reporting was effective as of December 31, 2007.

     PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited and issued their report on the effectiveness of our internal control over financial reporting as of December 31, 2007, which appears herein.

Changes in Internal Control

     There have been no changes in our internal control over financial reporting during our quarter ended December 31, 2007 that have materially affected, or is reasonable likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Repros Therapeutics, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations and cash flows for each of the three years in the period ended December 31, 2007, and the statements of stockholders’ equity for each of the six years in the period ended December 31, 2007 present fairly, in all material respects, the financial position of Repros Therapeutics, Inc. and its subsidiary (collectively, the “Company”), a development stage company, at December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, and cumulatively for the period January 1, 2002 through December 31, 2007 (not separately presented) in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our audits (which were integrated audits in 2007 and 2006). We did not audit the cumulative totals of the Company for the period from August 20, 1987 (date of inception) to December 31, 2001, which totals reflect a deficit of $75.8 million accumulated during the development stage. The cumulative totals for the period January 1, 1994 to December 31, 2001 were audited by other auditors who have ceased operations. Those auditors expressed unqualified opinions on the consolidated financial statements for the three years in the period ended December 31, 2001, the three years in the period ended December 31, 2000, the three years in the period ended December 31, 1999, the three years in the period ended December 31, 1998, the three years in the period ended December 31, 1997, and the three years in the period ended December 31, 1996 dated February 6, 2002, February 2, 2001, February 2, 2000, January 26, 1999, March 24, 1998, and March 11, 1997, respectively. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company is a development stage company, has an accumulated deficit, and has experienced negative cash flows that raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to this matter are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for share based payments in 2006.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Zonagen, Inc.:

We have audited the accompanying consolidated balance sheets of Zonagen, Inc. (a Delaware corporation in the development stage), and subsidiary (collectively, “the Company”) as of December 31, 2001 and 2000, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2001. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Zonagen, Inc., and subsidiary as of December 31, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States.

As explained in Note 2 to the consolidated financial statements, effective January 1, 2000, the Company changed its method of accounting for revenue recognition.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Zonagen, Inc.:

We have audited the accompanying consolidated balance sheets of Zonagen, Inc. (a Delaware corporation in the development stage), and subsidiary as of December 31, 1996 and 1995, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 1996. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted audited standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1 to the consolidated financial statements, the Company has operated as a development stage enterprise since its inception by devoting substantially all of its efforts to raising capital and performing research and development. In order to complete the research and development and other activities necessary to commercialize its products, additional financing will be required. Management’s current projections indicate that the Company can conserve its cash resources to maintain the Company’s operations through 1997. Management’s plans in regard to those matters are also described in Note 1.

In our opinion, based on our audits, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Zonagen, Inc., and subsidiary as of December 31, 1996 and 1995, and the results of their operations and cash flows for each of the three years in the period ended December 31, 1996, in conformity with generally accepted accounting principles.
