Sino Biopharm (HK.1177) announced on March 8 that TDI01 suspension, a Class I innovative drug developed independently by its subsidiary Beijing Tide Pharmaceutical Co., Ltd, was approved by National Medical Products Administration on March 3, 2022 to conduct clinical trials for pneumoconiosis. According to the official website of the National Medical Products Administration Drug Review Center, TDI01 is an oral small molecule drug with a new target and a new mechanism, and is a highly selective Rho/Rho-related coiled-coil-forming protein kinase 2 (ROCK2) inhibitor, which is listed as a major new drug creation in the 13th Five-Year Plan of China. It is the first-in-class drug in the field of pulmonary fibrosis and non-alcoholic steatohepatitis, which are the indications for clinical trials.

Sino Biopharm was the first company in China to focus on the ROCK2 target. In October 2020, TDI01 was approved to conduct clinical trials for idiopathic pulmonary fibrosis in China, and this time for the second indication of pneumoconiosis. In 2021, TDI01 entered into an overseas licensing cooperation agreement with the US company Graviton Bioscience, with a total deal value of US$517.5 million, which set the highest record for foreign licensing of an oral small molecule drug in China at that time. TDI01 has completed Phase I clinical trials in the U.S. with a favorable safety profile, and is currently conducting a bridge trial in China, Tide revealed.
