Theratechnologies Confirms Issuance of U.S. Patent Covering the Use of Tesamorelin in the Treatment of Individuals Suffering From NAFLD/NASH

MONTREAL, Oct. 13, 2020 (GLOBE NEWSWIRE) -- Theratechnologies Inc. (Theratechnologies) TH THTX, a biopharmaceutical company focused on the development and commercialization of innovative therapies, is pleased to announce that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,799,562, which is directed to the treatment of Nonalcoholic Steatohepatitis (NASH) and/or Nonalcoholic Fatty Liver Disease (NAFLD) in patients using tesamorelin.

This patent, which is scheduled to expire in 2040, stems from a patent application filed in March 2020 by Massachusetts General Hospital (MGH). Theratechnologies has an exclusive license with MGH to this patent.

"This is another step in further strengthening our position relating to the development and potential commercialization of tesamorelin for the treatment of NASH. With close to 20 years of intellectual property protection in the United States, we can progress with our development plans knowing we can fully reap the benefits of the ambitious plans we have for tesamorelin," said Paul Lévesque, President and Chief Executive Officer, Theratechnologies Inc. "We also plan on filing patent applications in other jurisdictions to expand our protection of tesamorelin."

Tesamorelin for the treatment of NASH in the general population
On September 10, 2020, Theratechnologies announced its intention to pursue the development of tesamorelin for the treatment of NASH in the general population by submitting a Phase 3 study protocol to the United States Food and Drug Administration (FDA) and with European regulatory agencies in the fourth quarter of 2020. Subject to feedback from regulatory agencies, Theratechnologies aims at beginning a Phase 3 clinical trial during the first quarter of 2021.

Theratechnologies intends to use a new investigational formulation of tesamorelin, known as "F8", for the conduct of such Phase 3 clinical trial. The Company is also working on the development of a convenient, multi-dose pen injector using the F8 formulation.

The risks and uncertainties include, among others, the risk that tesamorelin does not prove to be a safe and effective drug for the treatment of NASH, that the FDA and European regulatory agencies do not allow us to proceed with a Phase 3 clinical trial without conducting a Phase 2b or earlier study in the general NASH population, that we do not meet the endpoints of the Phase 3 clinical trial, that we are unable to enroll a sufficient number of patients to show clinical benefits from the use of tesamorelin, that unknown side effects of tesamorelin are discovered, that our intellectual property is challenged and held to be invalid or infringing upon third parties' intellectual property, that the development of a multi-dose pen is not successful, that we are unable to finance the Phase 3 clinical trial and our business plan, and that competing drugs are or may become available and more successful than ours.
