MONTREAL, Canada I May 24, 2016 I Theratechnologies Inc. (Theratechnologies) (TH.TO) announces that it has been notified by its partner, TaiMed Biologics, Inc., of the preliminary results for the primary end point of the phase III trial with ibalizumab in patients with multi-drug resistant HIV-1 (TMB-301).
Preliminary results indicate that 82.5% of patients enrolled in the phase III study (33/40, p-value <0.0001) have met the primary endpoint of a decrease of ≥ 0.5 log10 in viral load following a 7-day treatment period with ibalizumab. This result is statistically significantly better than results observed during the control period. The administration of ibalizumab was well tolerated during the first week of treatment. TaiMed plans to submit an abstract to present these results at a major scientific conference later this year.
“We are excited by these results. Ibalizumab is the first monoclonal antibody for the treatment of HIV to reach phase III and these primary endpoint results indicate that we are moving closer to providing a new treatment option for HIV patients with very limited alternatives”, said Dr. Jay Lalezari, Medical Director, Quest Research and Principal Investigator of the TMB-301 clinical trial.
This Phase III study is the last clinical trial required by the U.S. Food and Drug Administration (FDA) to complete the Biologics Licence Application (BLA) submission. The 24-week treatment study is well underway and should be completed before the end of October 2016.
“Ibalizumab continues to perform well in clinical trials, both in terms of safety and efficacy. We are actively collaborating with our partner, TaiMed, to ensure that all activities related to the BLA will be completed in due time. We have also recently initiated activities to support the successful launch of ibalizumab in the United States, if approved by the Food and Drug Administration” said Luc Tanguay, President and Chief Executive Officer of Theratechnologies.
TMB-301 is a single arm, 24-week study of ibalizumab plus optimized background regimen (OBR) in treatment experienced patients infected with multi-drug resistant HIV-1. The primary objective of the study is to demonstrate the antiviral activity of ibalizumab 7 days after the first dose of ibalizumab. Patients receiving their current failing ART regimens were monitored during a 7 day control period. Thereafter, a loading dose of 2000mg of intravenous ibalizumab was the only ART added to their regimen. The primary efficacy endpoint is the proportion of patients achieving a ≥ 0.5 log10 decrease in HIV-1 RNA 7 days after initiating Ibalizumab therapy, day 14 of the study. Ibalizumab is continued at doses of 800mg IV every two weeks through 24 weeks on study treatment. Safety and additional efficacy endpoints are evaluated during the study.
