Overview

This is a multicenter, open-label, Randomized, phase Ib/II clinical study to evaluate the anti-tumor efficacy, safety, tolerability, and PK of IN10018 in combination with anti-PD-1/L1 monoclonal antibody (Tislelizumab is proposed as the combination drug) and chemotherapy (platinum and etoposide) as the first-line treatment in Extensive-stage small cell lung cancer (ES-SCLC).
