Montreal, Canada – March 6, 2018 – Theratechnologies Inc. (Theratechnologies) (TSX:TH) and its partner TaiMed Biologics, Inc. (TaiMed) today announced that the U.S. Food and Drug Administration (FDA) has granted approval of Trogarzo™ (ibalizumab-uiyk) Injection. In combination with other ARTs, Trogarzo™ 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.1

Trogarzo™ represents a critical new treatment advance as the first HIV therapy with a new mechanism of action approved in 10 years and proven effectiveness in difficult-to-treat patients with limited options. Unlike all other classes of ARTs, Trogarzo™ is a CD4-directed post-attachment HIV-1 inhibitor that binds to CD4+ receptors on host cells and blocks the HIV virus from infecting the cells.[i]

“Today’s approval of Trogarzo™ by the FDA is great news for people infected with difficult-to-treat multidrug resistant HIV. We look forward to bringing this much-needed therapy to patients in the U.S within six weeks,” said Luc Tanguay, President and Chief Executive Officer, Theratechnologies Inc. “We are grateful to the patients, investigators, as well as the FDA who supported the clinical development of Trogarzo™, and are helping address this critical unmet medical need.”

Trogarzo™ previously received Breakthrough Therapy and Orphan Drug designations as well as Priority Review status from the FDA, underscoring the significance of the treatment for this patient population.

“I witnessed some of the earliest cases of HIV and AIDS, at a time when the diagnosis was terrifying to patients because in many cases it was a death sentence,” said David Ho, M.D., chief scientific advisor of TaiMed and scientific director and CEO of the Aaron Diamond AIDS Research Center. “Since then, treatment advances and the discovery that combinations of ARTs was the best way to bring viral load below the level of detection have allowed most people to manage HIV like a chronic condition and live long, healthy lives. However, this is not the reality for people whose HIV is resistant to multiple drugs and whose viral load is not controlled, which is why TaiMed dedicated the past decade to advancing ibalizumab in the clinic. For these patients, it represents the next breakthrough.”

Up to 25,000 Americans with HIV are currently multidrug resistant, of which 12,000 are in urgent need of a new treatment option because their current treatment regimen is failing them and their viral load has risen to detectable levels, jeopardizing their health and making HIV transmittable.[ii]-13 The best way to prevent the transmission of multidrug resistant HIV is to control the virus in those living with it. According to new guidance from the Centers for Disease Control and Prevention (CDC), the HIV virus cannot be transmitted if it is being fully suppressed.13
