NEW YORK, Aug. 21, 2024 (GLOBE NEWSWIRE) -- SIGA Technologies, Inc. (SIGA) (NASDAQ:SIGA), a commercial-stage pharmaceutical company and leader in infectious diseases, today announced a new contract with the U.S. Department of Defense (DOD) for the procurement of approximately $9 million of TPOXX^® (Contract number: W911SR24C0030). This award is comprised primarily of oral TPOXX^®, with a small amount of intravenous (IV) TPOXX^®, and represents the third procurement contract award from the DOD over the past three years.

"We are pleased to announce this new contract, continuing our long-term partnership with the Department of Defense. Providing TPOXX^® plays a critical role in protecting and supporting our military personnel against orthopoxvirus risks, such as smallpox. This underscores our commitment to ensuring the safety of our troops while also developing innovative treatments that benefit people worldwide as we advance the PEP indication," said Diem Nguyen, Chief Executive Officer.

Inclusive of this award, SIGA currently has approximately $154 million of outstanding oral and IV TPOXX^® orders, of which more than 85% of this amount was generated within the past three months.
