TH 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 that the production of EGRIFTA SV® has resumed following a voluntary shutdown of the Company’s contract manufacturer’s facility to address observations from an inspection by the US Food and Drug Administration (FDA).

One newly manufactured batch of EGRIFTA SV® has completed standard quality control and will be available for release to the market upon approval from the FDA of a Prior Approval Supplement, which the Company is expected to file around mid-December 2024. The manufacturing of two additional batches of EGRIFTA SV® is currently underway. The Company implemented measures to carefully manage existing inventory levels of EGRIFTA SV® to meet patient demand until mid-January 2025.

Theratechnologies continues to collaborate closely with the relevant divisions of the FDA and other key stakeholders to avoid a shortage at the patient level in 2025.

The Company will update the market on any further material developments.

EGRIFTA SV® is distributed in the United States only.
