OncoMatch/Clinical Trials/NCT06848699
A Phase Ib/II Clinical Study to Evaluate HLX43 in Combination With Serplulimab in Patients With Advanced/Metastatic Solid Tumors
Is NCT06848699 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments for solid tumor cancer.
Treatment: HLX43 dose 1 · HLX43 dose 2 · HLX43 dose 3 · HLX43 dose 4 · HLX43 dose 5 · Serplulimab — The study is being conducted to explore the reasonable dosage and evaluate the efficacy, safety and tolerability of HLX43 (Anti-PD-L1 ADC) in combination with Serplulimab (anti-PD-1 humanized monoclonal antibody injection) in patients with advanced/metastatic solid tumors
