MONTREAL, July 24, 2017 /PRNewswire/ -- Theratechnologies Inc. (Theratechnologies) (TSX: TH) announced today that results
The Phase II data for ibalizumab, a long-acting monoclonal antibody, show no significant difference in susceptibility (measured by maximum percent inhibition or ICHALFMAX Fold Change) in patient HIV isolates that were either sensitive or resistant to other antiretroviral agents, including nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, integrase strand transfer inhibitors, enfuvirtide and maraviroc.
"HIV drug resistance is a key topic at the IAS conference this year, and these findings are particularly important as they suggest that ibalizumab is equally active against HIV whether it is resistant or responsive to approved antiretroviral agents," said Steve Weinheimer, Vice President, Biological Sciences at TaiMed Biologics USA. "On the heels of the BLA acceptance for priority review, these data provide additional support for ibalizumab as a potential tool for the treatment of multidrug resistant HIV-1," added Mr. Weinheimer.
In a retrospective analysis of datasets from two, multicenter, randomized placebo-controlled trials of EGRIFTA® among HIV-infected adults with lipodystrophy, fat in trunk muscles decreased and trunk muscle area increased over 26 weeks in patients with excess visceral adipose tissue (VAT, abdominal fat) who had shown a clinical response to EGRIFTA® (VAT decrease of 8 percent or more). These results were seen across a number of trunk muscle groups and were independent of the change in amount of VAT for many of the measures.
"This is the first study to evaluate changes in trunk muscle fat (both abdominal and spine musculature) in HIV patients who have responded to tesamorelin," said Kristine Erlandson, MD, Assistant Professor of Medicine, Divisions of Infectious Disease and Geriatric Medicine, University of Colorado. "We are pleased to continue to uncover new information on the potential effects of tesamorelin in HIV patients with excess abdominal fat," added Dr. Erlandson.
EGRIFTA® is not indicated for trunk muscle fat decrease.
Ibalizumab is an investigational humanized monoclonal antibody being developed for the treatment of multidrug resistant HIV-1 infection. Unlike other antiretroviral agents, ibalizumab binds primarily to the second extracellular domain of the CD4+ T cell receptor, away from major histocompatibility complex II molecule binding sites. It potentially prevents HIV from infecting CD4+ immune cells while preserving normal immunological function.
Ibalizumab is active against HIV-1 resistant to all approved antiretroviral agents.
Ibalizumab is currently under review by the FDA following the acceptance of a Biologics License Application on June 30, 2017.
INDICATION AND IMPORTANT RISK INFORMATION FOR EGRIFTA®

The forward-looking statements contained in this press release include, but are not limited to, the approval of ibalizumab in the United States for the treatment of MDR HIV-1 infected patients, the effect of ibalizumab to treat HIV and, more particularly, the treatment of multidrug resistant HIV-1, and the growth of Theratechnologies based on such approval.
Forward-looking statements are based upon a number of assumptions and are subject to a number of risks and uncertainties, many of which are beyond Theratechnologies' control that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. These assumptions include but are not limited to, the following: ibalizumab will be approved by the FDA for the treatment of MDR HIV-1 infected patients and, if approved, Theratechnologies will have set-up on time the necessary infrastructure to launch and commercialize ibalizumab in the United States, and ibalizumab will be well received by the marketplace. These risks and uncertainties include, but are not limited to, the risk that the FDA does not approve ibalizumab as a treatment for MDR HIV-1 infection and, if approved, that the FDA imposes a significant limitation on its use resulting in a smaller patient population who could benefit from ibalizumab, that additional clinical trials are requested to be conducted prior to approving, or post-approval of, ibalizumab, that sales of EGRIFTA® decrease or that untoward side effects become known leading to a recall or the withdrawal of EGRIFTA® from the market.
We refer potential investors to the "Risk Factors" section of our Annual Information Form (AIF) dated February 7, 2017 for additional risks and uncertainties about Theratechnologies. The AIF is available on the Company's website at www.theratech.com and on SEDAR at www.sedar.com.
