MONTREAL, Aug. 15, 2018 (GLOBE NEWSWIRE) -- Theratechnologies Inc. (Theratechnologies) (TSX: TH ) is pleased to announce that results from the phase III clinical trial used to obtain FDA approval for Trogarzo™ (ibalizumab-uiyk) injection in the United States were published in the most recent edition of The New England Journal of Medicine (NEJM). 1

Furthermore, the NEJM published an article, authored by the Office of the Antimicrobial Products of the FDA, giving rationale for the design of the phase III trial of Trogarzo™ that led to its approval.

The phase III, open-label study, enrolled 40 patients with multidrug-resistant (MDR) HIV-1 in whom multiple antiretroviral therapies had failed. All patients at baseline were experiencing viral failure. After a seven-day control period, patients received an intravenous 2000 mg loading dose of Trogarzo™ which was the only change made to their antiretroviral regimen. Through the 24-week treatment period of the study, patients were given a maintenance dose of 800 mg of Trogarzo™ every two weeks along with an optimized background regimen that included at least one additional fully active agent.

The primary endpoint of the study was the proportion of patients with a viral load reduction of at least 0.5 log 10 from baseline, 7 day after the loading dose.

The mean baseline viral load was 4.5 log 10 while the mean CD4 cell count was 150 per microliter. Of the 40 patients, 33 (83%) had a decrease in viral load of at least 0.5 log 10 from baseline. At the end of the 24-week treatment period, 43% of patients had a viral load lower than 50 copies per milliliter (considered below detection level) and 50% had a viral load of less than 200 copies per milliliter.

“The New England Journal of Medicine is among the most highly regarded peer-reviewed medical journals. It lends tremendous credibility to the Trogarzo™ phase III clinical trial results. The medical community, payers and treatment guideline authors will certainly welcome those peer-reviewed articles as it gives perspective and even more reassurance towards the utilisation of Trogarzo™”, said Luc Tanguay, President and CEO, Theratechnologies Inc.
