A Phase Ib Study of HS-10504 Combined Therapy in NSCLC

A Phase Ib Study of the Safety, Efficacy, Pharmacokinetics, and Immunogenicity of HS-10504 Combined Therapy in Advanced Non-small Cell Lung Cancer Patients

This is a multi-center, open-label, phase I study to evaluate the safety, efficacy, pharmacokinetics (PK), and immunogenicity of HS-10504 combined therapy in subjects with locally advanced or metastatic non-small cell lung cancer (NSCLC).
