THERATECHNOLOGIES ANNOUNCES END OF PATIENT TREATMENT FOR PHASE III IBALIZUMAB TRIAL

Theratechnologies Inc. has been notified by its partner, TaiMed Biologics Inc., that the last patient enrolled in the phase III study of ibalizumab, in combination with optimized background regimen, for patients infected with multidrug-resistant HIV-1, has completed the treatment phase of the study. The last patient was enrolled on April 24, 2016, and completed the week 25 visit last week. Patients who completed the trial are offered participation in the expanded access study. TaiMed and its clinical research organization are now completing the analysis of the data, and top-line results should be available in the coming weeks.

This open-label, single-arm phase III study is the last pivotal clinical trial required by the United States Food & Drug Administration (FDA) to complete the biologics licence application (BLA) submission. The primary end point, defined as the proportion of patients achieving a viral load reduction of at least 0.5 log 10 at day 14, was met successfully by 83 per cent of patients (33 out of 40). As previously disclosed, detailed primary end point data obtained after seven days of treatment will be presented as a late-breaker oral presentation at the ID Week 2016 medical conference in New Orleans at the end of this month.

About ibalizumab

Ibalizumab is a humanized monoclonal antibody developed for the potential treatment of HIV-1 infection. Unlike other anti-retroviral agents, ibalizumab binds primarily to the second extracellular domain of the CD4 receptor, away from major histocompatibility complex II molecule (MHC II) binding sites. It potentially prevents HIV virus from infecting CD4 plus immune cells while preserving normal immunological function. Ibalizumab is active against HIV-1 resistant to all approved anti-retroviral agents. Ibalizumab has been tested in phase I and II clinical trials, and the phase III study is the last pivotal clinical study necessary for the completion of the BLA.
