THTX Theratechnologies Inc

Theratechnologies Inc. (“Theratechnologies” or the “Company”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced the resubmission of its supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for the F8 formulation of tesamorelin, the only medication approved in the U.S. for the reduction of excess abdominal fat in adults with HIV who have lipodystrophy.

Theratechnologies has filed the resubmission to address concerns raised in the FDA’s Complete Response Letter (CRL) to the initial F8 formulation sBLA filing. In the CRL, which was issued in January 2024, the FDA requested clarifications largely related to chemistry, manufacturing and controls (CMC), as well as further information on immunogenicity risk.

“We are confident in our sBLA resubmission after discussing our response approach with the FDA in a Type A meeting,” said Christian Marsolais, Ph.D., Senior Vice President and Chief Medical Officer at Theratechnologies. “The F8 formulation of tesamorelin would simplify dosing for people with HIV who face the clinical challenges of excess abdominal fat. We look forward to further collaboration with the FDA as the agency reviews our updated application.”

The FDA will review the updated sBLA within four months of submission. Theratechnologies therefore expects a decision around the end of March 2025. The new formulation is patent protected in the U.S. until 2033.
