A Study of HS-10365 in Patients With Advanced or Metastatic RET Fusion-Positive Non-Small Cell Lung Cancer

This is an open-label, single arm, multi-center Phase 2 study in participants with treatment-naïve locally advanced or metastatic RET fusion-positive non-small cell lung cancer, which is designed to investigate the anti-tumor activity, safety and pharmacokinetics (PK) of HS-10365 at the recommended phase 2 dose (RP2D). HS-10365 will be administered orally twice daily until the occurrence of disease progression, unacceptable adverse events, withdrawal of consent, death or the end of the study. Primary endpoint is objective response rate (ORR) by Independent Reading Committee (IRC). Secondary and exploratory objectives include evaluation of secondary efficacy endpoints, safety and PK in the study population.
