结局指标
主要结局
Dose limiting toxicity (DLT) and adverse events (AEs)
时间窗: From subject sign the ICF to 30 days after the last dose of study treatment
Incidence and severity of adverse events (AEs) graded by Common Terminology Criteria for Adverse Events (CTCAE) v5.0.
Objective Response Rate (ORR)
时间窗: From baseline until disease progression, death or other protocol defined reason up to approximately 21 months
ORR is defined as the proportion of subjects with confirmed CR or PR as the best overall response assessed per RECIST 1.1.
Prostate-specific antigen (PSA) response rate (Cohort D)
时间窗: From baseline until disease progression, death or other protocol defined reason up to approximately 21 months
The percentage of subjects in the analysis population who have a negative change (decrease) in PSA level of ≥ 50% measured twice ≥ 3 weeks apart
