A Study of SYS6040 for Injection in Patients With Advanced Solid Tumors
Trial Parameters
Brief Summary
This study is the first-in-human Phase I study of SYS6040 for injection, comprising two phases: Dose escalation with backfill (Phase Ia) and cohort expansion (Phase Ib).The planned study population consists of subjects with advanced solid tumors.The objective is to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of SYS6040 for injection as monotherapy in participants with advanced solid tumors.
