Who We Are

SIGA Technologies, Inc. is a public, commercial-stage pharmaceutical company focused on providing solutions for unmet needs in the health security market that comprises medical countermeasures against biological, chemical, radiological, and nuclear (CBRN) threats, as well as emerging infectious diseases. The company is headquartered in New York City, with research and development facilities in Corvallis, Oregon.

In July 2018, the U.S. Food and Drug Administration (FDA) approved SIGA’s first product, oral TPOXX® (tecovirimat), for the treatment of smallpox.

Over 2 million courses of TPOXX® delivered to the Strategic National Stockpile

SIGA has been awarded more than $1.1 billion in procurement and development contracts by the Biomedical Advanced Research and Development Authority of the U.S. Government (BARDA). The most recent contract with BARDA, primarily for the maintenance of a strategic stockpile of 1.7 million courses of smallpox antiviral therapy, was awarded in September 2018 and has a value in excess of $600 million (if all options are exercised). In 2011, SIGA was awarded a contract with BARDA which led to the delivery of 2 million courses of oral TPOXX® to the strategic stockpile. Concurrent with the approval of TPOXX®, the FDA granted SIGA a Priority Review Voucher (PRV) that the company sold in October 2018 for cash consideration of $80 million.

More than $1 billion in contract value awarded by the U.S. government

SIGA has worked closely with the U.S. Government during the development of TPOXX® and has cultivated relationships with key health security constituencies in the U.S. government, including the Biodefense Advanced Research Development Authority (BARDA), the National Institute of Allergy and Infectious Diseases (NIAID)/National Institutes of Health (NIH), the Defense Threat Reduction Agency (DTRA), and the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). These relationships have generated consistent, long-term mutual benefits that have helped to advance the development of TPOXX® while enhancing U.S. national health security and preparedness against a potential smallpox threat.

Proven drug development capability including development under the Animal Rule

SIGA has established an end-to-end network with over 20 partners across discovery, pre-clinical, clinical, manufacturing and supply chain that supported development of TPOXX® and successful delivery of over 2 million courses to the SNS. In addition, development and approval of TPOXX®, the first drug approved to treat a disease that no longer exists in the human population, required a unique regulatory approach based on the FDA’s Animal Rule. We have developed a robust drug development capability supported through U.S government investment in Biodefense, and our highly externalized cost structure minimizes fixed costs and provides scalability. SIGA intends to leverage the unparalleled expertise, infrastructure, and relationships amassed in support of the TPOXX® program in additional health security opportunities.

Our Product

Smallpox is one of the deadliest threats and cannot be addressed with vaccines alone

Oral TPOXX® (tecovirimat) is the first drug approved by the U.S. Food and Drug Administration (FDA) that is specifically indicated for the treatment of smallpox disease in adults and pediatric patients weighing at least 13 kg. (Prescription Label) TPOXX® inhibits viral maturation of variola virus (the virus that causes smallpox) and other poxviruses by preventing the formation of a secondary viral envelope. In the absence of this envelope, viral particles remain inside the cell and cannot spread to and infect other cells.

TPOXX® is among the first novel small molecule therapies delivered to the Strategic National Stockpile (SNS) under Project BioShield, a U.S. government program designed to accelerate the research, development, purchase, and availability of effective medical countermeasures against biological, chemical, radiological, and nuclear (CBRN) agents. As the first antiviral agent specifically indicated for the treatment of smallpox, TPOXX® would play a critical role in responding to a smallpox bioterror attack.
