“Yves has been an excellent CEO for Theratechnologies. He was the right leader at the right time and was able to bring focus and discipline to the Company during a time when it was greatly needed. Under his direction, Theratechnologies produced results that culminated into a Company that is well positioned for growth in the future,” commented Mr. Paul Pommier, Chairman of the Board of Directors of Theratechnologies. “On behalf of the Board of Directors, I would like to thank Yves for his dedication and hard work over the past six years and wish him all the best during his retirement,” said Mr. Pommier.

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.
