- Clinical trial application clearances received for a Phase 1a/1b trial for ABI-5366 targeting recurrent genital herpes, and a Phase 1b trial for ABI-4334 in chronic HBV infection; both studies on track to initiate by mid-2024
- ABI-5366 interim Phase 1a first-in-human data expected in Q3 2024 and ABI-4334 interim Phase 1b data expected by end of year
SOUTH SAN FRANCISCO, Calif., May 08, 2024 (GLOBE NEWSWIRE) -- Assembly Biosciences, Inc. (Nasdaq: ASMB), a biotechnology company developing innovative therapeutics targeting serious viral diseases, today reported financial results and recent highlights for the first quarter ended March 31, 2024.
“We are pleased that we now have regulatory clearance to initiate trials evaluating our promising investigational therapies ABI-5366 and ABI-4334 and look forward to sharing interim data from these studies later this year,” said Jason Okazaki, chief executive officer and president of Assembly Bio. “These clearances are a significant step toward our goal of reaching key clinical inflection points for multiple programs in our antiviral pipeline by year end. Our continued clinical progress reflects the strength and agility of our highly experienced team and our singular focus of improving treatment options for those living with serious viral diseases.”
First Quarter 2024 and Recent Highlights
- Two clinical trial applications received clearance to proceed:
- ABI-5366, a long-acting herpes simplex virus (HSV) helicase-primase inhibitor candidate, for initiation of Phase 1a/1b clinical studies in both healthy volunteers and in individuals with recurrent genital herpes
- ABI-4334, a next-generation, highly potent capsid assembly modulator candidate, for initiation of a Phase 1b study in individuals with chronic hepatitis B virus (HBV) infection
- An abstract highlighting preclinical data for ABI-6250, an oral, small molecule HBV/hepatitis delta virus (HDV) entry inhibitor candidate, has been accepted for poster presentation at the European Association for the Study of the Liver (EASL) CongressTM 2024, June 5-8, 2024
Anticipated 2024 Milestones
- ABI-5366 and ABI-4334 studies expected to initiate by mid-2024:
- ABI-5366 Phase 1a interim clinical data expected in Q3 2024 and interim Phase 1b data expected in the first half of 2025
- ABI-4334 Phase 1b interim clinical data expected by the end of 2024
- Two additional candidates are anticipated to enter the clinic by the end of 2024:
- ABI-1179, a long-acting HSV helicase-primase inhibitor contributed by Gilead Sciences, Inc. (Gilead) under the collaboration between Assembly Bio and Gilead
- ABI-6250, a small molecule orally-bioavailable HDV entry inhibitor
First Quarter 2024 Financial Results
- Cash, cash equivalents and marketable securities were $113.0 million as of March 31, 2024, compared to $130.2 million as of December 31, 2023. Assembly Bio’s cash position is projected to fund operations into the second half of 2025.
- Revenues from collaborative research were $5.8 million for the three months ended March 31, 2024. There was no revenue recognized for the same period in 2023. Revenue for the three months ended March 31, 2024 consists of amounts recognized under the collaboration with Gilead.
- Research and development expenses were $11.9 million for the three months ended March 31, 2024, compared to $14.5 million for the same period in 2023. Increased expenses related to the development of ABI-1179 and ABI-6250 were more than offset by savings from the discontinuation of ABI-H3733 and vebicorvir as well as reduced employee and contractor-related expenses.
- General and administrative expenses were $4.6 million for the three months ended March 31, 2024, compared to $5.0 million for the same period in 2023. The decrease is primarily due to a decrease in non-cash stock-based compensation expense.
- Net loss attributable to common stockholders was $9.1 million, or $1.66 per basic and diluted share, for the three months ended March 31, 2024, compared to $19.0 million, or $4.46 per basic and diluted share, for the same period in 2023.
