About Theratechnologies

Theratechnologies (TSX:TH) is a specialty pharmaceutical company that discovers and develops innovative therapeutic peptide products, with an emphasis on growth-hormone releasing factor peptides. Its first product, EGRIFTA^® (tesamorelin for injection), was approved by the United States Food and Drug Administration in November 2010. To date, EGRIFTA^® is the only approved therapy for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. EGRIFTA^® has not been approved in Canada.

EGRIFTA^® is currently marketed in the United States by EMD Serono pursuant to a collaboration and licensing agreement executed in October 2008. In addition, Theratechnologies has signed distribution and licensing agreements with a subsidiary of Sanofi granting them the exclusive commercialization rights for EGRIFTA^® for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy in Latin America, Africa and the Middle East and with Ferrer Internacional S.A. granting them the exclusive commercialization rights for EGRIFTA^® for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy in Europe, Russia, South Korea, Taiwan, Thailand and certain central Asian countries.

Theratechnologies is also looking to develop tesamorelin for the treatment of
muscle wasting associated with Chronic Obstructive Pulmonary Disease (COPD). Tesamorelin has been shown to increase muscle mass, which makes it a potential treatment for muscle wasting. The COPD clinical program is expected to begin in September 2011.
