Toripalimab Combined With Beat Chemotherapy in the Treatment of Advanced Back-line Small Cell Lung Cancer

July 9, 2026 updated by: Henan Cancer Hospital

A Prospective, Open-label, Bayesian Adaptive Randomized Phase II Clinical Study of Toripalimab Combined With Beat Chemotherapy in the Treatment of Advanced Back-line Small Cell Lung Cancer

This study is a randomized, open-label, multi-center investigator-initiated clinical trial. Patients who meet the inclusion criteria receive the treatment plan stipulated in the protocol. A Bayesian design is used to explore the efficacy and safety of teprotumumab combined with pulse chemotherapy in the treatment of advanced second-line extensive-stage small cell lung cancer.
