Will be estimated using the Kaplan-Meier method, and a 95% confidence interval for median PFS will be estimated using the Brookmeyer-Crowley approach.
Clinical benefit rate is defined as complete response, partial response, and/or stable disease at six months. Clinical response will be assessed every 6 weeks for the first 24 months and every 12 weeks thereafter using Response Evaluation Criteria in Solid Tumors 1.1 criteria. Will be estimated as a proportion, with an exact 95% confidence interval estimated using the Clopper-Pearson method.
OS will be estimated using the Kaplan-Meier method, and median survival will be calculated. A 95% confidence interval will be estimated using the Brookmeyer-Crowley approach.
Safety will be determined according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5. Frequencies and percentages will be used to summarize safety events.
