About Transgene in China

Transgene has been present in China since 2010 via Transgene Tasly (Tianjin) BioPharmaceutical Co., Ltd., a joint venture equally owned with Tasly Biopharmaceuticals Co., Ltd., a major player in healthcare in China. The joint venture was a Chinese corporation created to develop biotechnology products, including certain of Transgene’s immunotherapies. The joint-venture held development rights to T101 and the development and commercial rights of T601. As a result of the transactions between Transgene and Tasly Biopharmaceuticals, Tasly Biopharmaceuticals holds 100% ownership of the joint venture.

About T101

T101 is a targeted immunotherapy candidate for the treatment of chronic hepatitis B, based on a viral vector expressing three HBV antigens. It has been designed by Transgene’s infectious diseases research team, based on the technology of Transgene’s therapeutic vaccine TG1050. The first results from a Phase 1/1b clinical trial conducted in Europe and North America have confirmed the good tolerability profile of TG1050 in patients with chronic hepatitis B receiving standard antiviral therapy.

T101 is currently evaluated in China in a Phase 1 clinical trial. The first data readout from the study is expected at the beginning of 2019.

About T601

T601 is a next generation oncolytic immunotherapy, based on the patented suite of transgenes integrated in TG6002. It has been designed to induce the breakdown of cancer cells (oncolysis) and allow the local production of chemotherapy (5-FU) in the tumor.

T601 is a modified Vaccinia virus, with double gene deletion (TK-RR-) and expressing the FCU1 gene in the cancer cells it has infected, leading to the local production of 5-FU, a widely used cancer chemotherapy. The oncolytic virus T601 has shown efficacy and good safety profile in several preclinical models. A Phase 1 trial of T601 is actively being prepared (solid cancers including gastrointestinal tumors).

A Phase 1 trial of TG6002 is currently recruiting glioblastoma patients in France; another Phase 1 trial is expected to start around the end of 2018 in Europe in patients with advanced gastrointestinal tumors.
