About

This study is a single-arm, randomized, open-label, multi-cohort Phase Ib clinical trial. The experimental drug is TQB2858 Injection. The trial was divided into 3 cohorts. Cohort 1 included patients with advanced nasopharyngeal carcinoma who had previously failed platinum-based chemotherapy and immune checkpoint inhibitors (programmed cell death protein 1 (PD-1)/ Programmed death-ligand 1 (PD-L1), etc.). Cohorts 2 and 3 were randomized into patients with advanced, untreated nasopharyngeal carcinoma who had not received prior systemic therapy. A total of 60-90 subjects are required.

Enrollment: 90 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
