Awarded $55 Million by Federal Government to Develop Broader Applications for Its Lead Drug Candidate ST-246 - 09/03/2008
NEW YORK, September 3, 2008 -- SIGA Technologies, Inc. , a company specializing in the development of pharmaceutical agents to fight bio-warfare pathogens, today announced that it has been awarded a contract of $55 million from the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health (NIH), and The Office of the Biomedical Advance Research and Development Authority (BARDA), within the Department of Health and Human Services, to support development of additional formulations and smallpox-related indications for ST-246, SIGA's lead drug candidate. ST-246 is a potent, non-toxic inhibitor of orthopoxviruses that is in advanced development efforts to obtain regulatory approval.

In contrast to SIGA's previously awarded and ongoing $16.5 million ST-246 development contract, this new funding enables the formulation and advanced development of a new ST-246 parenteral drug product as well as new ways to use the existing oral formulation of ST-246 to combat smallpox. Success would significantly enhance the utility of ST-246 and substantially expand the biodefense indications for SIGA's original oral formulation.

Commenting on the contract, Dr. Dennis E. Hruby, SIGA's Chief Scientific Officer and Principal Investigator on the award, stated, "These funds will support all the studies needed to gain regulatory approval for these new indications. Formulation development, animal efficacy, human safety evaluations, and manufacturing are among the activities needed. We have already developed extensive evidence with respect to the safety and efficacy of ST-246 as a treatment for exposed individuals, and we are excited to see this project advance to include other indications and formulations."

Commenting on the contract, SIGA's Chief Executive Officer Eric Rose stated, "This new contract will broaden the use and utility of ST-246 as an orthopoxvirus (e.g., smallpox) countermeasure. It paves the way for ST-246 to provide protection to a much larger portion of the population in the event of a smallpox attack."
