         Hemispherx Biopharma Files New Drug Application for Ampligen(R)
                    as Treatment of Chronic Fatigue Syndrome

        NDA of investigational drug includes four well-controlled trials,
                 more than 1,200 trial subjects and 90,000 doses

Philadelphia,  Pennsylvania--October 11, 2007--Hemispherx Biopharma, Inc. (AMEX:
HEB)  announced  today that it has filed a New Drug  Application  (NDA) with the
U.S.  Food  and  Drug  Administration  (FDA)  for its  experimental  therapeutic
Ampligen(R), also known as Poly I : Poly C12U, to treat Chronic Fatigue Syndrome
("CFS"). The Company is also moving forward as planned with filings in countries
outside the United States.

According to data from the Centers for Disease Control ("CDC"),  Chronic Fatigue
Syndrome may now affect more than 1 million  people in the United  States alone,
causing an  economic  impact  estimated  at more than $9 billion  annually.  The
Centers  for  Disease  Control  refers to CFS as a "...  disabling  disease,  as
disabling as other severe  chronic  conditions  like  multiple  sclerosis,  COPD
[Chronic  Obstructive  Pulmonary  Disease] and  rheumatoid  arthritis"  in their
ongoing public  awareness  campaign  launched in 2006. The condition may also be
associated with early death due to secondary depression/suicide and cancer.

Over its developmental  history,  the experimental  therapeutic  Ampligen(R) has
received various designations,  including Orphan Drug Product Designation (FDA),
Emergency   (compassionate)   Cost  Recovery  Sales   Authorization   (FDA)  and
"promising"  designation by the Agency on Health Research  Quality (AHRQ).  Four
well  controlled,  or pivotal,  trials are now being  reported in their entirety
within  Hemispherx  Biopharma's  NDA  submission,  which  covers more than 1,200
subjects evaluated with approximately 90,000 dose administrations.

The  experimental  therapeutic  was  originally  discovered and developed at The
Johns Hopkins University and thereafter licensed to Hemispherx.  On December 29,
2006, the FDA received the Company's  pre-submission of pre-clinical information
and assigned an NDA number.  The Company will now move forward  promptly  with a
series of  scientific  and  medical  peer-reviewed  publications  on the audited
database contained within the NDA application.

William A. Carter,  M.D.,  Chief  Executive  Officer and Chairman of Hemispherx,
commented:  "The  comprehensive  data  package  being  submitted  today has been
possible because of the guidance,  and scientific  support,  of the FDA, the CDC
and CFS Advisory  Committees to both the government and the private sector.  Our
profound gratitude goes out to the teams of independent  clinical  investigators
around the country and  especially,  to the  individuals  afflicted with CFS who
supplied the courage and will to sustain the research,  clinical and  regulatory
communities in their continuing  search for better  understanding and management
of CFS."

The  bioactivity of the  experimental  therapeutic,  Ampligen(R),  as noted in a
peer-reviewed  Journal of  Immunology  study and reported by Hemispherx on April
30, 2007, may be based on its binding to the human  toll-like  receptor 3 (TLR3)
and activating subsequent signaling cascades.  Toll-like receptors such as TLR-3
serve as "pattern recognition" receptors in the early detection of pathogens and
the establishment of early defense mechanisms  (innate immunity).  As such, they
may be critical to the first line of immunological defense against a broad range
of pathogens, such as otherwise lethal viruses and various forms of cancer.

About Chronic Fatigue Syndrome
Chronic  Fatigue  Syndrome  (CFS) has a top  priority  status at the Centers for
Disease Control and Prevention,  the governmental agency responsible for disease
surveillance,  as a serious and  debilitating  disease in the U.S.  The disorder
reflects a major unmet medical need.  There are currently no approved  therapies
for CFS. The Agency for Research and Quality,  a health  service arm of the U.S.
Department  of  Health  and  Human  Services,   reported  that  Ampligen(R),  an
experimental  therapeutic,  yielded the most promising  clinical results to date
related to CFS. It should be noted that only  federal  regulatory  agencies  can
determine whether any experimental therapeutic is "safe and effective" for wider
distribution outside of the existing authorized clinical trials.
