Theratechnologies receives Complete Response Letter from FDA for the F8 formulation of tesamorelin sBLA

MONTREAL, Jan. 24, 2024 — Theratechnologies Inc. (“Theratechnologies” or the “Company”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) in response to the Company’s supplemental Biologics License Application (sBLA) for the F8 formulation of tesamorelin. The Company will address the FDA’s request and intends to pursue approval of this newer formulation of tesamorelin.

The questions outlined in the CRL are largely related to chemistry, manufacturing and controls (CMC) concerning the microbiology, assays, impurities and stability for both the lyophilized product and the final reconstituted drug product. In addition, the FDA requested further information to understand the potential impact of the proposed formulation on immunogenicity risk.

“While we are disappointed to receive a Complete Response Letter from the FDA for the F8 formulation of tesamorelin containing questions that were not raised during the review process, we plan to address these new comments as swiftly as possible,” said Christian Marsolais, Ph.D., Senior Vice President and Chief Medical Officer at Theratechnologies. “We remain focused on bringing this new formulation of tesamorelin to market as part of our commitment to innovate and simplify treatments for people with HIV.”

The Company will continue to commercialize EGRIFTA SV^®, which is the only approved treatment in the U.S. for the reduction of excess abdominal fat in adults with HIV who have lipodystrophy.
