           FDA EXTENDS HEMISPHERX'S NDA REVIEW DATE FOR AMPLIGEN(R)AS
                          POTENTIAL TREATMENT FOR CFS


                   Extended User Fee Goal is now May 25, 2009

Philadelphia,  PA, February 18, 2009 - Hemispherx  Biopharma,  Inc. (AMEX - HEB)
has received a letter from the Food and Drug Agency ("FDA")  indicating that the
originally  scheduled  Prescription  Drug  User  Fee Act  ("PDUFA")  date on the
Ampligen(R)  (Poly I:Poly C12U) New Drug Application  (NDA) would be extended by
three  months "in order to provide  time for a full  review of the  submission."
Additional  data were  received  by the FDA within 3 months of the user fee goal
date.

Due to constraints at the FDA, specifically and including the increased workload
related to the recently  enacted and  implemented  FDA Amendments Act ( "FDAAA")
and  FDA's  Safety  First/Safe  Use  initiatives,  work  priorities  may  change
resulting in the Agency going past the  customary  PDUFA goal set for reviews of
an application.

A decision  was  originally  expected by February 25,  2009,  for the  Company's
submission of its Ampligen(R) NDA, which is designated as an Orphan Drug for the
treatment of Chronic Fatigue Syndrome,  which has no FDA approved  treatments on
the market.  Ampligen(R) is also authorized for Emergency  (compassionate)  Cost
Recovery Sales Authorization by the FDA and has a "promising" designation by the
Agency on Health Research Quality (AHRQ): "Ampligen(R),  an investigational drug
that is not approved by the FDA,  given  intravenously  to severely  debilitated
patients,  yielded the most promising  results." The extended user fee goal date
is now May 25th, 2009.

Extensions of NDA reviews are a separate category of FDA response, distinct from
a complete  response  letter or  approval  by the PDUFA  date,  and have  always
existed.  Prior to the recent new FDA  initiatives  (cited  above) and resultant
increased workload,  "on time" action by the Agency has generally ranged between
68 and 100 percent  for the  standard  NDA  reviews  between FY 1999 and FY 2006
