Brief Summary

HS-20093 is a fully humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. The objectives of this study are to investigate the safety, tolerability, pharmacokinetics and efficacy of HS-20093 in combination with other anti-cancer agents in patients with advanced metastatic colorectal cancer.

Detailed Description

This is a phase 1b, open-label, multi-center, dose-escalation and expansion, phase 1b study in Chinses subjects with advanced metastatic colorectal cancer. This study is in design allowing assessment of safety, tolerability, pharmacokinetics and efficacy of HS-20093 in combination with other anti-cancer agents.

A total of 5 combination-treatments will be carried out in 5 cohorts. The target population of dose escalation part is patients have progressed on or intolerant to available standard therapies, and the dose expansion part will enroll patients who have not received treatment for advanced metastatic colorectal cancer.

All patients will be carefully followed for adverse events during the study treatment and for 90 days after the last dose of study drug. Subjects will be permitted to continue therapy with assessments for progression if the product is well tolerated and sustained clinical benefit exists.
