About

This dose escalation and dose expansion study is to evaluate and characterize the tolerability, safety, pharmacokinetics and efficacy profile of single agent KY-0118 in Locally Advanced or Metastatic Solid Tumor Patients.

Full description

For Phase Ia It aims to evaluate the safety, tolerability, pharmacokinetic characteristics, pharmacodynamic effect, immunogenicity in subjects with locally advanced or metastatic solid tumor patients , and determine the appropriate dose of KY-0118.

For Phase Ib it aims is to further evaluate the efficacy, safety, tolerability, pharmacokinetic properties, pharmacodynamic effects and immunogenicity of KY-0118 with appropriate dose groups (approximately 3-5 dose groups) in different Administration manner.
