the efficacy and safety of ldp in patients with urinary and male genital tumors

Conditions: Bladder Cancer; Renal Carcinoma; Advanced Penile Carcinoma

Summary: this is a single-arm,open, multicenter, phase ii clinical study of the efficacy and safety of human anti-pd-l1 monoclonal antibody injection (ldp) in the treatment of urinary and male genital tumors.

this trial is a single arm, open, multicenter, ⅱ period clinical research. three cohorts were included, 127 subjects were enrolled (cohort 1: about 60 subjects with surgically suitable muscular-invasive bladder cancer; cohort 2: about 40 subjects with advanced non-clear cell renal carcinoma; cohort 3: about 27 subjects with advanced penile carcinoma. after confirmation of inclusion, intravenous infusion of 10mg/kg human anti-pd-l1 monoclonal antibody injection (ldp) was given. the initial efficacy and safety of drugs in different tumor species in the cohort above will be observed.
