Theratechnologies Regains Japanese Rights for TH9507

MONTREAL, QUEBEC--(Marketwire - July 17, 2007) - Theratechnologies (TSX:TH) today announced that it has entered into an agreement with Sakai Chemical Industry Co. Ltd. ("Sakai") to regain exclusive rights for its lead compound, TH9507, in Japan. Under the terms of this agreement, the rights were returned to Theratechnologies without financial compensation. The Company believes that there is strategic value in owning the worldwide rights to TH9507.

The Company had licensed its TH9507 in 2002 for hip fracture, with options for immune response, sleep and chronic obstructive pulmonary disorder indications. The Company had granted an additional option for other indications. At the time, Theratechnologies was conducting clinical trials in these four indications; however, since the signing of this licensing agreement, Theratechnologies has focused its TH9507 clinical efforts on lipodystrophy, a disease experienced in patients infected with HIV. Recently, Sakai has made the strategic decision not to exercise any of its options and has agreed to return the rights for Japan, and all options for all indications, back to Theratechnologies.

"We see regaining the exclusive worldwide rights to TH9507 as an opportunity," commented Mr. Yves Rosconi, President and CEO of Theratechnologies. "All of the data we have presented thus far indicate that our product may offer an attractive combination of efficacy and safety with potential advantages over other approaches being developed for HIV-associated lipodystrophy. With the full rights to TH9507 we will re-evaluate our business strategy in Asia and include Japan in discussions with potential partners for markets outside of North America. This provides us more flexibility, and could help generate more value from TH9507 for our shareholders," Mr. Rosconi stated.

The Company also announced that Phase 3 clinical data will be discussed on July 19th at the 9th International Workshop in adverse drug reaction and lipodystrophy in HIV, in Sydney, Australia.

HIV-associated Lipodystrophy

HIV-associated lipodystrophy is characterized by a change in the distribution of adipose tissue (fat containing tissue), dyslipidemia and glucose intolerance. The changes in fat distribution include visceral fat accumulation and/or loss of subcutaneous fat, generally in the limbs and in the face. There is no treatment available for the accumulation of visceral fat found in patients with HIV-associated lipodystrophy. It is estimated that approximately 250,000 HIV-infected patients in North America and Europe suffer an excessive accumulation of visceral fat.
