Forest plot of subgroup analyses of ORR (mITT). High ORRs were observed in all subgroups analyzed in the mITT population, and efficacy was maintained irrespective of prior treatments. The 50th percentile for duration of cGVHD before enrollment was 29 months. Response assessments performed on or after the initiation of a new systemic therapy for cGVHD were excluded from the analysis. Pooled responses across arms, unless stated otherwise. *CI was calculated using the Clopper-Pearson interval (exact) method. †Indicates stratification factors. C1D1, cycle 1 day 1; PPI, proton pump inhibitor.
