SIGA Announces $13 Million of International Procurement Orders for Oral TPOXX® (Tecovirimat)

NEW YORK, June 23, 2022 (GLOBE NEWSWIRE) -- SIGA Technologies, Inc. (SIGA) (NASDAQ: SIGA), a commercial-stage pharmaceutical company focused on the health security market, today announced approximately $13 million of procurement orders for oral TPOXX (tecovirimat), including $11 million for initial procurement from two new international jurisdictions and an approximate $2 million order from a country in the Asia Pacific region that has an established contract for oral TPOXX (tecovirimat).

“Procurement orders from new international jurisdictions have occurred as SIGA has received a large and ongoing number of inquiries about accessing oral TPOXX, highlighting the importance of health security preparedness,” said Phil Gomez, CEO of SIGA. “We expect a portion of the courses of oral TPOXX delivered under these orders will be used for the treatment of active monkeypox cases and represent a first step in the response to this outbreak by the global public health community. By increasing both the scale and scope of TPOXX stockpiling, countries can be better prepared for the outbreak risks of smallpox, monkeypox, and other viruses in the orthopoxvirus family of viruses and make sure that patients are able to access a proven safe and effective treatment.”

The orders from the new international jurisdictions represent the first procurements of oral TPOXX (tecovirimat) directly in response to the evolving global monkeypox outbreak. One of the new jurisdictions is located in Europe and the other is located in the Asia Pacific region. SIGA currently expects to deliver approximately $4 million of oral TPOXX (tecovirimat) under the two new contracts within the next 45 days. The remaining approximately $7 million of oral TPOXX (tecovirimat) is expected to be delivered in 2023. With respect to the order from an existing customer, SIGA recently fulfilled the order by delivering $2 million of oral TPOXX (tecovirimat). In combination with a delivery of a previously disclosed order of $2.8 million, SIGA has delivered in total approximately $5 million of oral TPOXX (tecovirimat) to this country during this quarter.

Meridian Medical Technologies, LLC (Meridian) is the counterparty to the international contracts and SIGA will be responsible for the manufacture and delivery of product. “The recent cases of monkeypox are another reminder of how the emergence and re-emergence of infectious diseases continue to present global public health threats and underscore the critical importance of pandemic preparedness efforts,” said Tom Handel, Chief Commercial Officer at Meridian. “We are pleased to partner with SIGA to meet the demand for antiviral treatment, leveraging our company’s six decades of leadership in health security to ensure governments around the world are prepared to meet its health emergency needs and stockpiling requirements.”

On July 13, 2018, the US Food and Drug Administration (FDA) approved oral TPOXX for the treatment of smallpox to mitigate the impact of a potential outbreak or bioterror attack. In December 2021, oral TPOXX was approved for the same indication by Health Canada. Tecovirimat (TPOXX) was approved by the European Medicines Agency (EMA) in January 2022 with a broader label that covers the treatment of smallpox, monkeypox, cowpox, and complications from vaccination for smallpox.

About Smallpox

Smallpox is a contagious, disfiguring and often deadly disease that has affected humans for thousands of years. Naturally-occurring smallpox was eradicated worldwide by 1980, the result of an unprecedented global immunization campaign. Samples of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent. A vaccine can prevent smallpox, but the risk of the current vaccine's side effects is too high to justify routine vaccination for people at low risk of exposure to the smallpox virus.
