MONTREAL, CANADA--(Marketwire - June 4, 2012) - Theratechnologies Inc. (TSX:TH) (NASDAQ:THER) today announced that a marketing authorization application for tesamorelin has been submitted with regulatory agencies in Colombia and Venezuela. Sanofi, Theratechnologies' commercial partner in those countries, filed the application as part of its distribution and licensing agreement for tesamorelin.

Tesamorelin is proposed for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy. Theratechnologies estimates that there are approximately 11,000 and 16,000 HIV-infected patients in treatment suffering from excess abdominal fat in Venezuela and Colombia, respectively. At this time, there are no approved treatments available for this condition in Latin America. In this territory, Sanofi also filed applications for tesamorelin in Argentina, Brazil and Mexico in 2011, all of which are currently under review.

"Latin America is a significant territory for tesamorelin, with a potential patient base of over 200,000," said Mr. John-Michel T. Huss, President and Chief Executive Officer of Theratechnologies. "This represents one more step towards developing the full potential of this unique treatment. As the number one healthcare company in Latin America, Sanofi will be in a solid position to successfully commercialize tesamorelin once regulatory approvals are granted," concluded Mr. Huss.

Theratechnologies signed a distribution and licensing agreement with Sanofi on December 6, 2010, granting them exclusive commercialization rights for tesamorelin for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy in Latin America, Africa and the Middle East.

Additional applications for tesamorelin for the treatment of excess abdominal fat in HIV-infected patients with lipodystrophy are also currently under review with regulatory agencies in Europe, Canada and Israel.

About HIV-Associated Lipodystrophy

Several factors, including a patient's antiretroviral drug regimen and the HIV virus itself, are thought to contribute to HIV-associated lipodystrophy, which is characterized by body composition changes. The changes in body composition may include accumulation of excess abdominal fat, which is known as abdominal lipohypertrophy.
