Comment
EMA/FDA approvals were based on an initial cohort of 55 patients (with median DoR/PFS not reached). The presented results refer to an extended cohort of 159 patients (with available medians for DoR/PFS). For both cohorts, ORR was >60% (initial: 75%; extended: 79%), resulting in an MCBS score of 3, according to Form 3 (irrespective of median DoR/PFS).
