Study Groups

Cohort 1 SCT200+SCT-I10A

SCT200+SCT-I10A was given to patients who had failed previous platinum-based therapy. Among them, SCT200 was administered as 6 mg/kg/QW for 12 weeks and 8 mg/kg/Q2W maintenance by intravenous infusion; SCT-I10A was 200 mg/Q3W by intravenous infusion for no more than 2 years. Every 6 weeks is a treatment cycle. After the first dose, tumor assessment was performed every 6 weeks until the occurrence of PD, initiation of new antitumor therapy, withdrawal of informed consent, death, or loss of visit
