“…Two systematic reviews summarized the current landscape of immunotherapy trials. 14,15 Of the four phase-3 trials (CheckMate 914, IMmotion 010, KEYNOTE 564, and PROSPER), only KEYNOTE 564 showed an improvement in recurrence-free survival (RFS) in the immunotherapy arm (hazard ratio [HR] 0.63, 95% confidence interval [CI] 0.50-0.79). The pooled analysis revealed that most of the inconsistencies were due to variability between trials, and the pooled decrease in recurrence risk was 15% (pooled HR 0.85, 95% CI 0.69-1.04).…”
