Roche Holding AGRoche's licensed Tam-Peli met its phase III primary endpoint with a 54% reduction in death risk in relapsed SCLC, supporting global phase III plans

Roche announced that its collaborator MediLink released interim results from the randomized phase III TAISHAN-302 trial showing that Tam-Peli, also known as tambotatug pelitecan or YL201, beat topotecan in Chinese patients with relapsed small-cell lung cancer who progressed after prior platinum-based chemotherapy with or without a PD-L1 inhibitor. The trial met its primary endpoint of overall survival, with Tam-Peli reducing the risk of death by 54 percent, with median overall survival of 13.3 versus 9.4 months and a stratified hazard ratio of 0.46 at a p-value below 0.0001. Tam-Peli also extended median progression-free survival to 7.4 months from 2.8 months and achieved a confirmed objective response rate of 59.1 percent versus 9.7 percent. The results are being presented as a Late-Breaking Abstract during a Presidential Presentation at the IASLC 2026 World Conference on Lung Cancer in Seoul with simultaneous publication in The New England Journal of Medicine, and China's Center of Drug Evaluation has accepted the New Drug Application for filing. Roche, which holds development, manufacturing and commercialization rights for Tam-Peli worldwide outside mainland China, Hong Kong and Macau under a January 2026 exclusive licensing agreement with MediLink Therapeutics, said the data support plans to rapidly initiate global phase III trials.
