In this phase II, multicentre, single-arm study, 52 patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) received the anti-CD19 antibody-drug conjugate coltuximab ravtansine (55 mg/m(2) ) and rituximab (375 mg/m(2) ) weekly for 4 weeks, then every 2 weeks for 8 weeks. The primary endpoint was objective response rate (ORR) by International Working Group Criteria. The primary objective was to reject the null hypothesis of an ORR of ≤40%. Among 45 evaluable patients, the ORR was 31·1% (80% confidence interval [CI]: 22·0-41·6%) and the primary objective was not met. The ORR appeared higher in patients with relapsed disease (58·3% [80% CI: 36·2-78·1%]) versus those refractory to their last (42·9% [80% CI: 17·0-72·1%]) or first-line therapy (15·4% [80% CI: 6·9-28·4%]). Median progression-free survival, overall survival and duration of response were 3·9 [80% CI: 3·22-3·98], 9·0 [80% CI: 6·47-13·67] and 8·6 (range: 0-18) months, respectively. The pharmacokinetics of both drugs were unaffected by co-administration. Common adverse events included gastrointestinal disorders (52%) and asthenia (25%). No patients discontinued due to adverse events. In conclusion, coltuximab ravtansine with rituximab was well tolerated and yielded clinical responses in a subset of patients with relapsed/refractory DLBCL.
