Trial Outcomes & Findings for Azacitidine and Pembrolizumab in Treating Patients With Myelodysplastic Syndrome (NCT NCT03094637)
NCT ID: NCT03094637
Last Updated: 2023-03-22
Results Overview
Will estimate the ORR for the experimental treatments, along with the 95% credible intervals. The association between ORR and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.

PRIMARY outcome
Timeframe: Up to 4 yearsWill be estimated using the method of Kaplan and Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log-rank tests. Overall Survival will be presented by median survival, which is the time point at which the cumulative survival drops below 50%. If there is no median survival (not reached), it means the cumulative survival was more than 50%.
