Theratechnologies Inc. Receives Patent Protection in Brazil for Tesamorelin

MONTREAL, QUEBEC, CANADA--(Marketwire - December 29, 2009) - Theratechnologies (TSX: TH) today announced that the Brazil Patent and Trademark Office has issued Patent Number 9608799-4 entitled "Chimeric fatty body-pro-GRF analog with increased biological potency and pharmaceutical formulation" for its lead-compound, tesamorelin. The granting of this patent provides protection in Brazil until December 2019.

"This patent aligns us well in executing one of our top priorities, which is to expand commercialization into various geographies for tesamorelin in HIV-associated lipodystrophy," commented Mr. Yves Rosconi, President and Chief Executive Officer of Theratechnologies. "Brazil is a country where there are patients in need and where we can leverage the work already completed for the U.S. regulatory agency. The patent announced today solidifies our approach and reinforces Brazil as an attractive territory for potential partners," concluded Mr. Rosconi.

About HIV-Associated Lipodystrophy

Several factors including the antiretroviral drug regimen and the virus itself are thought to contribute to HIV-associated lipodystrophy, which is characterized by body composition changes, dyslipidemia and glucose intolerance. The changes in body composition include excess abdominal fat accumulation. There is currently no approved treatment available for the excess abdominal fat related to HIV-associated lipodystrophy, a condition that can stigmatize patients and discourage HIV treatment adherence.

About Theratechnologies

Theratechnologies (TSX: TH) is a Canadian biopharmaceutical company with core expertise in peptide-based therapeutics. Its most advanced compound, tesamorelin, is an analogue of the human growth hormone-releasing factor.

In late 2008, Theratechnologies completed its Phase 3 clinical program evaluating tesamorelin in treating excess abdominal fat in HIV-infected patients with lipodystrophy. In addition, the Company signed a collaboration and licensing agreement with EMD Serono, Inc., for the commercialization of tesamorelin in the United States.

With a New Drug Application recently filed with the U.S. authorities, Theratechnologies' growth strategy is firmly focused on the development of tesamorelin, in the United States and in other potential HIV-associated lipodystrophy markets, as well as through additional clinical programs for other medical conditions.
