+Added: The Tecovirimat-SIGA marketing authorizations under “exceptional circumstances” are subject to certain specific obligations to gather additional data post-approval to help confirm the product’s safety and efficacy.
+Added: All “exceptional circumstances” marketing authorizations are subject to annual reassessments that consider whether data generated pursuant to the specific obligations continue to confirm its positive benefit-risk profile.

+Added: In the referral procedure, CHMP reviewed all available data on the safety and efficacy of Tecovirimat-SIGA for all its authorized indications in order to make a recommendation to the European Commission whether the marketing authorization should be maintained, modified, suspended or withdrawn.
+Added: The CHMP is expected to meet in March to issue its recommendation.
+Added: The Company expects the CHMP will confirm the positive benefit-risk balance of Tecovirimat-SIGA as a treatment for smallpox, cowpox, and vaccinia complications, and maintain those indications in the product label.

+Added: In the UK, Tecovirimat-SIGA is undergoing an annual reassessment by the MHRA.
+Added: This reassessment, which is ongoing, is substantially similar to the EMA’s annual reassessment process and could result in a similar outcome.
With respect to the regulatory approvals by the EMA, PMDA, MHRA and Health Canada, oral tecovirimat represents the same formulation approved by the FDA in July 2018 under the brand name TPOXX®.
