New 48-Week Data Presented at IDWeek Show Trogarzo® Remains Safe and Effective

MONTREAL, Oct. 03, 2019 (GLOBE NEWSWIRE) — Theratechnologies Inc. (Theratechnologies) (TSX: TH) is pleased to announce that new 48-week data from the TMB-311 extension study confirm that Trogarzo® provides durable viral suppression and a safety profile consistent with the 24-week pivotal Phase III study. Study results were presented today at IDWeek in Washington, D.C.
Results come from the expanded access protocol of TMB-311. A total of 38 patients were enrolled in Cohort 2. Patients had a viral load >1,000 copies/mL, resistance to at least 1 antiretroviral from three different classes and full viral sensitivity to at least 1 antiretroviral.In Cohort 2 patients, viral load reduction at week 24 and week 48 was comparable. Respectively, 46 percent and 47 percent of patients taking Trogarzo® and an optimized background regimen consisting of at least one fully active agent reached a viral load reduction below 50 copies/mL. Furthermore, at both timepoints, the median viral load reduction was -2.6 log10 copies/mL. This far exceeds the initial targeted endpoint of ≥ 0.5 log10 viral load reduction in the phase III trial.Importantly, a viral load below 50 copies/mL is considered undetectable and patients cannot transmit HIV.About Trogarzo®Trogarzo® is a CD4-directed post-attachment HIV-1 inhibitor. Trogarzo®, in combination with other antiretroviral(s), is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in heavily treatment-experienced adults with multidrug resistant HIV-1 infection failing their current antiretroviral regimen.Before you receive Trogarzo®, tell your healthcare provider if you are pregnant or plan to become pregnant as it is not known if Trogarzo® may harm your unborn baby or if you are breastfeeding or plan to breastfeed as it is not known if Trogarzo® passes into breast milk.Tell your healthcare provider about all the medicines you take, including all prescription and over-the-counter medicines, vitamins, and herbal supplements.Changes in your immune system (Immune Reconstitution Inflammatory Syndrome) can happen when you start taking HIV-1 medicines. Your immune system might get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your health care provider right away if you start having new symptoms after starting your HIV-1 medicine.The most common side effects of Trogarzo® include: diarrhea, dizziness, nausea, cough, fatigue and rash. These are not all the possible side effects of Trogarzo®. For more information, ask your healthcare provider or pharmacist.
