Theratechnologies Presents Results From Trogarzo® IV Push Administration Study at CROI 2022

• No serious adverse events observed
• No difference in viral load between IV Push and IV Infusion and no anti-drug antibodies detected
  
  

MONTREAL, Feb. 16, 2022 (GLOBE NEWSWIRE) -- 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 presentation of positive results from the Phase 3 study evaluating an intravenous (IV) push method of administration of Trogarzo^® for the treatment of human immunodeficiency virus type 1 (HIV-1). The results, presented as a poster at the held virtually February 12–16, 2022, demonstrated that there was no significant difference in pharmacokinetics between IV Push and IV Infusion of Trogarzo^®.

“We are pleased to present the positive results of our Trogarzo^® IV Push study to the scientific community,” said Christian Marsolais, Ph. D., Senior Vice President and Chief Medical Officer of Theratechnologies. “With the recently submitted supplemental Biologics License Application, we are optimistic that this more convenient IV push mode of administration will improve convenience for both patients and health care providers, thereby allowing patients to benefit from long-acting protection against HIV-1 when Trogarzo^® is administered with other antiretrovirals.”

Key data and conclusions from the poster include:

• The Phase 3 study met the primary endpoint with a 90% confidence interval of the ratio of IV Push to IV Infusion, within the target value of 0.80–1.25 (0.9478–1.1226);
• The proportion of subjects with mean trough serum drug concentration equal or exceeding the target concentration was 18/19 (94.7%) for both forms of administration;
• No serious adverse events (AEs) were observed, and only one treatment-related adverse event was observed. All AEs were considered mild to moderate. Additionally, there were no clinically significant differences in the occurrence of AEs during IV Infusion or IV Push; and
• Two secondary endpoints were also achieved, demonstrating no difference in HIV-1 viral load due to the change from IV Infusion to IV Push and no detection of anti-Trogarzo^® antibodies.

Poster Presentation Details

Presentation Title: IV Push Administration of Ibalizumab: Pharmacokinetics, Safety and Efficacy

Poster number: 429

Session: G01 – What's New in Pharmacokinetics, Pharmacogenetics, And Drug Interactions

Presenter: Edwin DeJesus, MD

The TMB-302 Phase 3 study, conducted by the Company’s partner, TaiMed Biologics (TaiMed), evaluated the safety and comparability of the current Trogarzo^® IV Infusion mode of administration with a more convenient IV Push form of administration that can be infused within 30 seconds without dilution compared to the 15-minute infusion time of the original IV Infusion. The Company submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) based on these results in December 2021. We are pleased to announce that the FDA has accepted our filing and has provided a target action date of October 3, 2022 in accordance with the Prescription Drug User Fee Act (PDUFA).

A copy of the Poster will be available on our website shortly.
