Theratechnologies' Trogarzo® Approved by FDA for 30-Second Intravenous (IV) Push, Simplifying HIV Treatment for Heavily Treatment-Experienced Population

MONTREAL, Oct. 03, 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 that the United States Food and Drug Administration (FDA) approved Trogarzo® (ibalizumab-uiyk) for administration by intravenous (IV) push, a method by which the undiluted medication is "pushed" by syringe for faster administration into the body's circulation. In the U.S., Trogarzo®, in combination with other antiretrovirals (ARVs), is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in heavily treatment-experienced adults with multidrug-resistant virus failing their current ARV regimen.

The FDA originally approved Trogarzo®, a novel, long-acting monoclonal antibody, in March 2018 to be administered intravenously as a single loading dose followed by a 15-minute maintenance dose every two weeks. Following today's approval, the maintenance dose can be administered as an undiluted IV push over 30 seconds.

"Today marks an important milestone in our journey to improve the lives of people living with HIV who have been heavily treated," said Dr. Christian Marsolais, Chief Medical Officer, Theratechnologies. "The evolution of Trogarzo® administration from intravenous infusion to intravenous push means less preparation and treatment time in clinics for patients and their health care providers, possibly allowing for more clinics to administer this treatment. We are proud of our long-term commitment to bring much needed non-oral innovations to help shift the treatment paradigm for heavily treatment-experienced people living with HIV."

"We are grateful for continued innovation to help people living with HIV, and it is comforting to know that this group, which is rarely the focus of treatment advancements, now has a proven, more convenient treatment option," said Nelson Vergel, founder of the Program for Wellness Restoration (PoWeR). "The availability of treatments that are easier to administer is of real importance to all people with HIV, and this advancement could make it easier to suppress the virus and maintain undetectability."

The approval of the Trogarzo® IV push method of administration is based on study TMB-302, a Phase 3 trial that evaluated the safety and pharmacokinetic (PK) profile of an 800-mg dose of Trogarzo® once every two weeks administered via IV push. Results show that the safety and PK profile of Trogarzo® administered via IV push are similar to that of IV infusion administration. These findings were observed in the Phase 3 TMB-301 trial, which evaluated the safety and efficacy of Trogarzo® in treatment-experienced patients with multidrug-resistant HIV-1. In the TMB-301 trial, patients receiving Trogarzo®, in combination with other ARVs, experienced significant reductions in viral load and a clinically significant increase in CD4+ (T-cell) count. A total of 350 subjects have received Trogarzo® in the clinical development program, including 19 subjects who received Trogarzo® via IV push. Trogarzo® is also being studied for intramuscular injection administration in the continuation of the TMB-302 study. The study is now fully enrolled, with the last patient visit scheduled for November 2022.

About Trogarzo®

Trogarzo® is a long-acting, CD4-directed, post-attachment HIV-1 inhibitor. In the United States, Trogarzo® (ibalizumab-uiyk), 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 (MDR) HIV-1 infection failing their current antiretroviral regimen. In the European Union, Trogarzo® is approved for the treatment of adults infected with MDR HIV-1 for whom it is otherwise not possible to construct a suppressive antiviral regimen.

Trogarzo® is administered intravenously (IV) as a single loading dose of 2,000 mg followed by a maintenance dose of 800 mg every two weeks after dilution in 250 mL of 0.9% Sodium Chloride Injection, USP. The Trogarzo® maintenance dose can also be administered as an undiluted intravenous push over 30 seconds.

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 health care provider or nurse, or get medical help right away if you get any symptoms of an allergic reaction. Before you receive Trogarzo®, tell your health care 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 health care 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 and rash. Tell your health care 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 health care provider or pharmacist.

The Forward-Looking Statements contained in this press release include, but are not limited to, statements regarding the simplification and improvement of treatment for people living with HIV, the increase in the number of clinics that could administer Trogarzo®, the last patient visit scheduled for November 2022 related to the open-label intramuscular Phase 3 study and the expected results from such Phase 3 study administering Trogarzo® intramuscularly. Although the Forward-Looking Statements contained in this press release are based upon what the Company believes are reasonable assumptions in light of the information currently available, investors are cautioned against placing undue reliance on these statements since actual results may vary from the Forward-Looking Statements. Certain assumptions made in preparing the Forward-Looking Statements include that: the IV-push method of administration of the maintenance dose of Trogarzo® will be found to be simpler and more convenient and will allow more clinics to administer Trogarzo®, the timeline described therein for the last patient visit will be met, the results to be derived from the open-label intramuscular Phase 3 study using Trogarzo® will be at least equal or superior to those observed with the IV-push method of administration and, if and when filed to the FDA, the intramuscular administration of Trogarzo® will be approved by the FDA.
