结局指标
主要结局
Objective Response Rate (ORR)
时间窗: up to 24 months
ORR is defined as the percentage of patients who achieved a best overall response of Complete Response (CR) or Partial Response (PR), per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1) for target lesions as assessed by the Investigator: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
次要结局
- Overall survival (OS)(up to 24 months)
- Progression-Free Survival (PFS)(up to 24 months)
- Clinical Benefit Rate (CBR)(up to 24 months)
- Duration of Overall Response(DoR)(up to 24 months)
- Time to response (TTR)(up to 24 months)
- adverse event(AE)(Throughout the experiment, assessed up to 24 months.)
