2013/3/4 - Theratechnologies Inc.: Health Canada Issues Decision on Tesamorelin

"As a Canadian company, this is particularly disappointing. The decision made by Health Canada puts Canadian patients at a disadvantage to U.S. patients where EGRIFTA(TM) was approved more than two years ago. We are now looking at our alternatives with our commercial partner, Actelion, which could include appealing the decision made by TPD. We will make our decision known within the next 30 days," stated Luc Tanguay, President and CEO of Theratechnologies.

The NDS for EGRIFTA(TM) was originally submitted to Health Canada in June 2011. It was based on the results from two Phase 3 clinical trials, which enrolled more than 800 patients, and follows a marketing approval for EGRIFTA(TM) by the U.S. Food and Drug Administration received in November 2010.

Currently, there are no approved treatments for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy available in Canada.
