An Open-Label, Single-Arm, Dose-Exploration Study to Evaluate the Safety, Tolerability, Preliminary Efficacy and Pharmacokinetics of CT048 in Subjects with Advanced Solid Tumors
详细描述
This is an open-label, single-arm, dose-escalation and dose-expansion, single/multiple infusion(s) exploratory study to evaluate the safety, tolerability, PK/PD and preliminary efficacy of CT048 in patients with advanced CLDN18.2+ solid tumors who had failed to at least 1 prior line of treatment.
