About Theratechnologies

Theratechnologies (TSX:TH) is a Canadian biopharmaceutical company that discovers and develops innovative therapeutic products, with an emphasis on peptides, for commercialization. The Company targets unmet medical needs in specialty markets where it can retain all or part of the commercial rights to its products. Its most advanced compound, tesamorelin, is an analogue of the human growth hormone releasing factor. In 2009, Theratechnologies submitted a New Drug Application to the U.S. Food and Drug Administration (“FDA”), seeking approval of tesamorelin for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy. The Company’s growth strategy is centered on the commercialization of tesamorelin in the United States through an agreement with EMD Serono, Inc. for HIV-associated lipodystrophy. Moreover, Theratechnologies’ growth strategy will also derive from the commercialization of tesamorelin in other markets for HIV-associated lipodystrophy, as well as the development of clinical programs for tesamorelin in other medical conditions.
