Theratechnologies Receives Special Protocol Assessment From FDA for Second Pivotal Phase 3 Trial With TH9507

MONTREAL, QUEBEC--(Healthcare Sales & Marketing Network)--Aug 23, 2006 -- Theratechnologies (TSX:TH.TO ) today announced a Special Protocol Assessment (SPA) from the U. S. Food and Drug Administration for the design of its second pivotal Phase 3 trial evaluating TH9507 for the treatment of HIV-associated lipodystrophy. Company plans call for the new Phase 3 trial to start in the first quarter of 2007.

Theratechnologies launched its TH9507 pivotal Phase 3 program in March 2005. The first 412-patient clinical trial began in June 2005 and patient enrolment at 43 clinical sites across North America was completed on schedule in March 2006 with results expected around the end of this year. The second trial will test TH9507 in approximately 400 additional patients in North America and Europe. It is patterned after the first trial and is intended to confirm its results. The FDA has now formally evaluated the protocol for this second trial through the SPA process. The SPA provides the Company with binding written agreement that the proposed design and analysis of the study are adequate to support a marketing application provided the study is performed in accordance with the SPA and the results are successful.

"We view this SPA as insurance against some of the regulatory risks associated with our Phase 3 program," said Yves Rosconi, President and Chief Executive Officer of Theratechnologies. "The drug development landscape in HIV-associated lipodystrophy has evolved considerably since March 2005 when we first met the FDA to discuss our plans and we felt it would be prudent to validate our assumptions before embarking on the final leg of the program. The SPA tells us that our development strategy is on target and continues to meet regulatory requirements in the U.S. Of particular note, we have reconfirmed the primary end point as an 8% reduction in visceral adipose tissue (VAT) and obtained the FDA's approval of the statistical analysis approach that we will use to measure the change in VAT," Mr. Rosconi stated.
