Theratechnologies Launches Confirmatory Phase 3 Trial Testing TH9507 in HIV-Associated Lipodystrophy

MONTREAL, QUEBEC--(Healthcare Sales & Marketing Network)--Jan 31, 2007 -- Theratechnologies (Toronto Future:TH.TO ) announced today that it has enrolled the first patient in its second Phase 3 clinical trial testing TH9507 in HIV-associated lipodystrophy. The objective of the new study is to confirm, for regulatory purposes, the beneficial effects seen in the Company's first Phase 3 study, the top-line results of which were made public in December 2006.

"We are pleased to have initiated this second trial so soon after announcing positive results from the first Phase 3 trial in HIV-associated lipodystrophy," said Yves Rosconi, President and Chief Executive Officer. "Our first trial comfortably met its primary endpoint and we are aiming to repeat that result in this confirmatory trial. For the new trial, we expect to complete patient enrollment in the third quarter of this year, which will put us on course to announce results in the first quarter of 2008", Mr. Rosconi stated.

The new Phase 3 trial is a multi-center, double-blind, randomized, placebo-controlled study conducted in over 60 centers in the United States, Canada and Europe. The study, which is designed to confirm the results of the earlier Phase 3 trial, is examining the safety and efficacy of a daily administration of 2 mg of TH9507 for a period of 26 weeks. The primary endpoint is a reduction of visceral adipose tissue, or VAT, which is a risk factor for cardiovascular disease and type 2 diabetes.

In August 2006, the Company received a Special protocol Assessment (SPA) for this latest trial from the Food and Drug Administration (FDA) in the United States. A special protocol assessment documents the Agency's agreement that the design and planned analysis of a study adequately address objectives in support of a regulatory submission.

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.
