FDA APPROVES SIGA'S INVESTIGATIONAL NEW DRUG APPLICATION FOR ITS
SMALLPOX DRUG SIGA-246
New York, December 13, 2005 -- SIGA Technologies, Inc. (NASDAQ: SIGA) announced
today that the U.S. Food and Drug Administration (FDA) accepted its
Investigational New Drug (IND) application to begin Phase I clinical trials of
SIGA-246, its lead smallpox drug. In order to expedite the program, the FDA
granted SIGA-246 Fast-Track status.
SIGA Technologies will start Phase I clinical trials to evaluate SIGA-246 in
healthy volunteers. The Phase I human trials will be performed at the Biodefense
Clinical Research Branch of the National Institute of Allergy and Infectious
Diseases (NIAID), which is part of the federal government's National Institutes
of Health (NIH). The primary objective of the study will be to evaluate the
safety and tolerability of single escalating doses of SIGA-246.
SIGA-246, an orally active compound, has demonstrated significant antiviral
activity in various animal models of poxvirus disease, including the complete
protection of golden ground squirrels from lethal doses of monkeypox virus.
Smallpox virus, classified as a Category A agent by the Center for Disease
Control (CDC), is considered one of the most significant threats for use as a
biowarfare agent. It is easily transmissible from person to person, is hardy in
the environment, and can be readily delivered. Routine smallpox vaccinations
were discontinued in the United States in 1972. More than 223 million Americas
have never been vaccinated. Smallpox has high mortality rates (30%) with up to
90% morbidity. Weaponized smallpox virus may have an incubation period as short
as 7 days, allowing very little time for vaccine administration.
The use of current live vaccines for mass immunizations of the general
population is not recommended because available vaccines are known to cause
complications in certain individuals, including encephalitis, myocarditis,
disseminated vaccinia virus infection, and death. 10% to 20% of the population
cannot be vaccinated because of immunocompromised status or other medical
conditions. At present there is no smallpox treatment stockpiled for the general
Dr. Dennis E. Hruby, SIGA's Chief Scientific Officer, said, "A Phase I clinical
trial of SIGA-246 is a critical step towards insuring the availability of a
smallpox drug that can fight this dreaded disease without serious side effects.
This nation needs a self-administrable antiviral drug in order to provide
immediate protection in the event of the deliberate release of smallpox virus.
Based upon the data generated to date, we believe that SIGA-246 will be a safe
and effective drug for the treatment of smallpox."
SIGA's Chief Executive Officer, Bernard L. Kasten, MD stated, "The success of
SIGA-246 in animal trials and pre-clinical studies is very encouraging. We look
forward to initiating human safety trials and advancing SIGA-246 toward New Drug
Application approval." Dr. Kasten continued, "We appreciate the support we have
received from the NIAID and the NIH in bringing SIGA-246 to this stage of its

computational modeling in the design and development of novel products for the
prevention and treatment of serious infectious diseases, with an emphasis on
products for biological warfare defense. SIGA has the potential to
become a significant force in the discovery of vaccine and pharmaceutical agents
to fight emerging pathogens. SIGA's product development programs emphasize the
increasingly serious problem of drug resistant bacteria. In addition to
smallpox, SIGA has antiviral programs targeting other Category A viral
pathogens, including arenaviruses (Lassa Fever Virus, Junin, Macupo, Guanarito,
and Sabia), Lymphocytic choriomeningitis virus (LCMV), Dengue, the filoviruses,
Ebola and Marburg. For more information about SIGA, please visit SIGA's Web site
