Summary: This is an open-label, randomized, multi-cohort, multi-center, phase Ib/II study to evaluate the safety and efficacy of Adebrelimab plus Irinotecan Liposome (II) with or without Famitinib in patients with extensive-stage small cell lung cancer (ES-SCLC) pre-treated with immune checkpoint inhibitor(s).

Detailed description: This study is divided into two stages. Dose exploration will be conducted first, and after obtaining preliminary safety data it will be decided by investigator when to proceed with dose extension. The aim of this study is to observe and evaluate the safety and efficacy of Adebrelimab plus Irinotecan Liposome (II) with or without Famitinib.
