Theratechnologies Reports Positive 52-Week Phase 3 Results for its Lead Drug Candidate Tesamorelin

Safety and efficacy profile of tesamorelin consistent with previous results

MONTREAL, CANADA--(Healthcare Sales & Marketing Network)--Oct 1, 2007 -- Theratechnologies (Toronto:TH.TO ) today announced positive 52-week results of its Phase 3 clinical trial, evaluating the long-term safety profile of the Company's lead compound, tesamorelin (TH9507), in patients with HIV-associated lipodystrophy. The 52-week results are consistent with the safety profile observed in the first 26 weeks of treatment and show that tesamorelin is well tolerated. In addition, tesamorelin's efficacy is confirmed as patients on treatment for 52 weeks lost 18% of their visceral adipose tissue (VAT) compared to baseline.

"Our objective was to demonstrate long-term safety, and we have clearly achieved this. In addition, we continue to differentiate tesamorelin from other compounds being evaluated in HIV-associated lipodystrophy as having a favorable risk/benefit profile for patients," commented Mr. Yves Rosconi, President and Chief Executive Officer of Theratechnologies. "The long-term safety profile provides strong evidence that tesamorelin can be used safely to significantly reduce VAT, which is a risk factor for cardiovascular disease and Type 2 diabetes," Mr. Rosconi stated.

"The long-term treatment is very encouraging for patients treated with tesamorelin for 52 weeks and shows that tesamorelin when administered long term does not compromise its safety profile," commented Dr. Christian Marsolais, Vice President, Clinical Research for Theratechnologies.

"There does not appear to be a significant impact on glucose tolerance, which is important for the long-term treatment of HIV lipodystrophy. The results are important as no treatment is currently on the market and approved to reduce visceral adiposity in this population," commented Dr. Steve Grinspoon, Associate Professor of Medicine, Harvard Medical School, Director of the Massachusetts General Hospital Program in Nutritional Metabolism, and Lead Investigator for the tesamorelin trial in the United States.

"The data demonstrate that one year treatment with tesamorelin results in sustained VAT reduction. This provides a great deal of hope for patients with symptoms of HIV-associated lipohypertrophy," stated Dr. Julian Falutz, Director, HIV Metabolic Clinic, Montreal General Hospital, Assistant Professor, McGill University Medical School, and Lead Investigator for Canada.

Trial Design

For the first 26 weeks of the study, patients were either treated with tesamorelin (2mg per day) or placebo. Those patients receiving tesamorelin for the first portion of the study were re-randomized to receive either tesamorelin or placebo for an additional 26 weeks, generating a group of patients that have been treated for a total of 52 weeks. All patients who received placebo in the first 26 weeks were treated with tesamorelin from weeks 26 to 52. It is important to note that there is no patient group that received placebo for 52 weeks and therefore there is no direct placebo comparator for the group of patients that were treated for 52 weeks.

Safety Results

The primary objective for the extension phase of the study was to evaluate the safety profile of tesamorelin over a 52-week period. The safety profile in this extension phase replicated the safety data disclosed after 26 weeks of treatment. As experienced for the first six months of treatment, no issues related to glycemic control were observed after 52 weeks. The drop out rate for the patients treated with tesamorelin for 52 weeks of treatment was 16% as compared to 23% for the first six months of treatment.

Efficacy Results

Although the primary objective of the trial was to determine the long-term (52 weeks) safety profile of tesamorelin, additional interesting data emerged regarding the efficacy of tesamorelin. Those patients that were treated for 52 weeks experienced a total reduction of 18% VAT compared to baseline (p less than 0.001). Patients treated with tesamorelin for the first 26 weeks experienced a total of 15% VAT reduction (p less than 0.001). Finally, patients treated with tesamorelin for 26 weeks followed by placebo for 26 weeks regained VAT to levels comparable to their baseline values (-1.6%, p less than 0.191).

Additional Data

The analysis of additional data and secondary endpoints is ongoing and will be reported in future publications and scientific meetings. The first such meeting will be the European AIDS Conference in Madrid later this month.

HIV-associated Lipodystrophy

HIV-associated lipodystrophy is characterized by a change in the distribution of adipose tissue (fat containing tissue), dyslipidemia and glucose intolerance. VAT accumulation with its concomitant metabolic profile is known to be a risk factor for cardiovascular diseases. 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.
