In the 3 mg/kg dose group, among patients with at least 12 weeks of follow-up or study completion (n=18), the objective response rate (ORR) was 50.0%, and the disease control rate (DCR) was 88.9%. The median progression-free survival (PFS) has not yet been reached and remains under follow-up.
In the 1/1.5 mg/kg dose group, the median PFS was 5.5 months (95% CI: 1.5, 8.3), with a 12-month PFS rate of 30.7%, highlighting the potential long-term benefits of immunotherapy.
