Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| AE | 2-year | Number of participants with treatment-related adverse events as assessed by NCI-CTCAE V5.0 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| ORR | 1-year | Objective response rate (ORR): Defined as the proportion of patients who achieved a prespecified reduction in tumor volume and maintained a minimum duration, including cases with CR and PR. Objective tumor response was assessed by an independent review committee using the Response Assessment Criteria for solid Tumors (RECIST 1.1 criteria). |
| DCR | 1-year | The proportion of all subjects who were randomized and whose best overall response (BOR) was complete response (CR), partial response (PR), and stable disease (SD) according to RECIST1.1 criteria. |
| OS | 2-year | It was defined as the time between the start of randomization and the death of the subject from any cause and was calculated in the intention-to-treat population (ITT). |
