Clinical Trial Summary

A Randomized, double-blind, placebo-controlled, multi-center Phase 3 study evaluating efficacy, safety and pharmacokinetics of Trilaciclib In Extensive-Stage Small Cell Lung Cancer Patients Receiving Carboplatin combined with Etoposide or Topotecan The study consists of 2 parts: Part 1: safety run-in and pharmacokinetics evaluation of 12 ES-SCLC patients (6 each for first line and second/third line ES-SCLC patients); Part 2: randomized, double-blind, placebo-controlled efficacy confirmation study of 80 ES-SCLC patients (stratified by first line and second/third line ES-SCLC, ECOG PS [0-1 vs 2] and brain metastases. The study includes screening period, treatment period, safety follow-up and survival follow-up.
