About Theratechnologies

Theratechnologies (TSX: TH) is a Canadian biopharmaceutical company with core expertise in peptide-based therapeutics. Its most advanced compound, tesamorelin, is an analogue of the human growth hormone releasing factor.

In late 2008, Theratechnologies completed its Phase 3 clinical program which was designed to evaluate tesamorelin in treating excess abdominal fat in HIV patients with lipodystrophy. Theratechnologies also signed a collaboration and licensing agreement with EMD Serono, Inc., for the commercialization of tesamorelin in the United States.

With a New Drug Application filed with the U.S. authorities in May 2009, Theratechnologies’ growth strategy is firmly focused on the development of tesamorelin in the United States and in other potential HIV-associated lipodystrophy markets, as well as through additional clinical programs for other medical conditions.
