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.1
"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.2-13 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
"I've struggled with multidrug resistant HIV for almost 30 years and it was completely debilitating to feel like I had run out of options - I made no long-term plans," said Nelson Vergel, founder of the Program for Wellness Restoration (PoWeR) and Trogarzo™ patient. "Since starting treatment with Trogarzo™ six years ago and getting my viral load to an undetectable level, I have been my happiest, most productive self. Trogarzo™ is a new source of hope and peace of mind for people whose treatments have failed them, and I feel incredibly lucky to have been able to participate in the clinical trial program."
TaiMed and Theratechnologies partnered on the development of Trogarzo™ so patients who can benefit from the treatment have access to it. For patients who need assistance accessing Trogarzo™ or who face challenges affording medicines, Theratechnologies has a team of patient care coordinators available to help. Patients can get assistance and expert support by contacting THERA patient support™ at 1-833-23-THERA (84372).
"In Phase 3 ibalizumab trials, we saw marked improvements in patients' health who not only were heavily treatment-experienced and had limited remaining treatment options, but in cases they also had extremely high viral loads and significantly impaired immune systems," said Edwin DeJesus, M.D., Medical Director for the Orlando Immunology Center. "As an investigator for ibalizumab clinical trials over nearly 10 years, it was remarkable and inspiring to see the dramatic effect ibalizumab had on such vulnerable patients. As a clinician, I am excited that we will now have another option with a different mechanism of action for our heavily pretreated patients who are struggling to keep their viral load below detection because their HIV is resistant to multiple drugs."
Clinical Trial Findings
Clinical studies show that Trogarzo™, in combination with other ARTs, significantly reduces viral load and increases CD4+ (T-cell) count among patients with multidrug resistant HIV-1.
The Phase 3 trial showed:1
Patients experienced a clinically-significant mean increase in CD4+ T-cells of 44 cells/mm3, and increases varied based on T-cell count at baseline. Rebuilding the immune system by increasing T-cell count is particularly important as people with multidrug resistant HIV-1 often have the most advanced form of HIV.1
The most common drug-related adverse reactions (incidence ? 5%) were diarrhea (8%), dizziness (8%), nausea (5%) and rash (5%). No drug-drug interactions were reported with other ARTs or medications, and no cross-resistance with other ARTs were observed.1
About Trogarzo™ (ibalizumab-uiyk) Injection
Trogarzo™ is a humanized monoclonal antibody for the treatment of multidrug resistant HIV-1 infection. Trogarzo™ binds primarily to the second extracellular domain of the CD4+ T receptor, away from major histocompatibility complex II molecule binding sites. It prevents HIV from infecting CD4+ immune cells while preserving normal immunological function.
IMPORTANT SAFETY INFORMATION
Trogarzo™ is a prescription HIV medicine that is used with other antiretroviral medicines to treat human immunodeficiency virus-1 (HIV-1) infections in adults.
Trogarzo™ blocks HIV from infecting certain cells of the immune system. This prevents HIV from multiplying and can reduce the amount of HIV in the body.
Before you receive Trogarzo™, tell your healthcare provider if you:
Tell your healthcare provider about all the medicines you take, including all prescription and over-the-counter medicines, vitamins, and herbal supplements.
Trogarzo™ can cause serious side effects, including:
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:
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.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. You may also report side effects to at 1-833-23THERA (1-833-238-4372).
