Over the study period, 115 (88%; CT-P10) and 111 (87%; rituximab) patients achieved overall response. At a median follow-up of 29·2 months (IQR: 26·1–33·7), median progression-free survival, time-to-progression, and overall survival were not estimable. The KM estimates (95% CI) for OS at 36 months were 98% (93–99) and 97% (89–99) in the CT-P10 and rituximab groups, respectively. Corresponding values for PFS were 80% (70–87) and 68% (54–79), while results for TTP were 82% (72–88) and 68% (54–79) in the CT-P10 and rituximab groups, respectively.
