Theratechnologies Announces Launch of Trogarzo® in Germany

First commercial launch in Europe

MONTREAL, Sept. 10, 2020 /PRNewswire/ -- Theratechnologies Inc. (Theratechnologies) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, is pleased to announce that Trogarzo^® will be commercially available in Germany as of tomorrow through its subsidiary, Theratechnologies Europe Limited.

Theratechnologies filed its health technology assessment for Trogarzo^® with the Gemeinsamer Bundesausschuss (GB-A), the German health authority. Based on German regulations, Trogarzo^® can be commercialized while the file is being reviewed by the GB-A.

"HIV treatments with new modes of action are essential to achieve and maintain viral suppression in clinical practice. In light of COVID-19, viral suppression is more important than ever. As the first monoclonal antibody for the treatment of HIV, Trogarzo^® will play a key role for patients needing a new option to construct a fully suppressive regimen," said Prof. Dr. Jürgen Rockstroh Senior Consultant at Bonn´s University Hospital and President of the European AIDS Clinical Society.

"The fight against HIV is not over. We need to continue to raise awareness about prevention, diagnosis and virologic control if we want to end the HIV epidemic. While a majority of people living with HIV are doing well and live long and productive lives, many are not as fortunate due to multidrug resistance and we must not forget them. They too should be able to aspire to reach an undetectable viral load. To that end, we are delighted to be able to launch this product this month in Germany and look forward to its wider commercial availability in Europe over the coming months," said Conor Walshe, General Manager, Theratechnologies Europe Limited

A recent study published in The Lancet Microbe concluded that "HIV-1 multidrug cross-resistance remains an important concern, despite the extensive number of antiretroviral drugs currently available. Highly treatment-experienced patients, especially those who have been given suboptimal combination ART, can develop highly complex resistance-associated mutation patterns, conferring cross-resistance to all widely available ARTs."[1]

"We are pleased and proud to enter the European market at such a crucial time in the fight against HIV. Trogarzo^® can become a cornerstone treatment for people living with multidrug-resistant HIV in Europe," said Mr. Paul Lévesque, President and Chief Executive Officer, Theratechnologies.
