MONTREAL, Oct. 13, 2023 (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 results from a study evaluating an intramuscular (IM) method of administration for Trogarzo® (ibalizumab-uiyk), a monoclonal antibody antiretroviral therapy (ART) for the treatment of heavily treatment-experienced adults with multidrug-resistant (MDR) HIV-1 infection failing their current antiretroviral regimen.
The TMB-302 study, conducted in partnership with TaiMed Biologics, enrolled 21 subjects (7 HIV-positive and 14 HIV-negative) to assess the pharmacokinetics, efficacy, and safety of IM administration of Trogarzo® as compared to intravenous (IV) infusion.
Mean Trogarzo® trough concentrations were greater than 15 µg/mL, suggesting that IM injection was sufficient at maintaining the drug trough concentration above the therapeutic level of 0.3 µg/mL. The mean trough concentrations were comparable between IV infusion and IM injection in HIV-positive subjects. However, the primary endpoint measuring a
Each study subject received IM maintenance doses for eight weeks of treatment and a total of 152 IM injections were administered, which were well tolerated. One subject reported injection-site pruritus (itching) at a single time point, and no subjects reported injection-site pain when Trogarzo® was administered intramuscularly.
With the TMB-302 data in hand, Theratechnologies is seeking expert advice prior to completing a regulatory submission of the Trogarzo® IM administration maintenance dose to the U.S. Food and Drug Administration (FDA). The FDA is currently reviewing the Company’s submission for the loading dose of the Trogarzo® IV push method of administration and a decision is expected in mid-December.

Important Safety Information
Do not receive Trogarzo® if you have had an allergic reaction to Trogarzo® or any of the ingredients in Trogarzo®. Trogarzo® can cause allergic reactions, including serious reactions, during and after infusion. Tell your healthcare provider or nurse, or get medical help right away if you experience any symptoms of an allergic reaction. Before you receive Trogarzo®, tell your healthcare provider about all of your medical conditions, including 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 healthcare 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, and rash. Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of Trogarzo®. For more information, ask your healthcare provider or pharmacist.
