History

TopAlliance Biosciences was established in December 2012 as a next-generation biopharmaceutical company dedicated to the discovery and development of innovative drugs and their clinical research and commercialization on a global scale.

In 2013, TopAlliance Biosciences established U.S. operations in Menlo Park, California.

In 2015, toripalimab received IND approval from the NMPA, marking the first anti-PD-1 monoclonal antibody developed by a Chinese company to reach that stage. Toripalimab, marketed as TUOYI, became the first product commercialized by the company. It is an anti-PD-1 monoclonal antibody injection that has delivered impressive clinical data and shown satisfying efficacy and safety across various indications. In the United States, the therapy is commercialized under the brand name LOQTORZI (toripalimab-tpzi) and received FDA approval.
