A Clinical Study to Evaluate HLX10 Monotherapy for the Treatment of MSI-H or dMMR Solid Tumors That Failed to Respond to Standard Therapy

Summary

It is a single-arm, open-label, multicenter, phase II clinical study to evaluate the clinical efficacy and safety of HLX10 monotherapy for the treatment of patients with unresectable or metastatic MSI-H or dMMR solid tumors who have progressed or intolerable after standard therapy.This study consists of three periods, screening period (28 days), treatment period and follow-up period (including safety follow-up, survival follow-up).Subjects can be enrolled into this study only if they meet inclusion criteria and do not meet exclusion criteria. The enrolled subjects will receive an intravenous infusion of HLX10 (3 mg/kg) once every 2 weeks until the loss of clinical benefit, death, intolerable toxicity, withdrawal of informed consent or other reasons as specified in the protocol, or up to the longest treatment duration-2 years (52 dosing periods) (whichever occurs earlier).
