a study of hs-10342 in patients with advanced solid tumor

Conditions: Advanced Solid Tumor

Summary: hs-10342 is a small molecular, oral potent, selective cdk4/6 inhibitor. the purpose of this study is to investigate the safety/tolerability and the pharmacokinetic profile of hs-10342 in chinese advanced solid tumor patients. preliminary efficacy will be also investigated in this study.

this is a phase 1, multicenter study to evaluate the safety, tolerability, pharmacokinetics and efficacy of hs-10342 in patients with advanced solid tumor by using a "3+3" dose escalation.
