A Phase 2 multicenter study of the anti-CD19 antibody drug conjugate coltuximab ravtansine (SAR3419) in patients with relapsed or refractory diffuse large B-cell lymphoma previously treated with rituximab-based immunotherapy. Haematologica. 2018 May 10;: Authors: Trněný M, Verhoef G, Dyer MJ, Yehuda DB, Patti C, Canales M, Lopez A, Awan FT, Montgomery PG, Janikova A, Barbui AM, Sulek K, Terol MJ, Radford J, Guidetti A, Di Nicola M, Siraudin L, Hatteville L, Schwab S, Oprea C, Gianni AM Abstract This phase 2, single-arm, multicenter study examined the efficacy and safety of coltuximab ravtansine (an anti-CD19 antibody drug conjugate) in 61 patients with histologically documented (de novo or transformed) relapsed or refractory diffuse large B-cell lymphoma who had previously received rituximab containing immuno-chemotherapy. Patients had received a median of 2.0 (range 0-9) prior treatment regimens for diffuse large B-cell lymphoma and almost half (45.9%) had bulky disease (≥ lesion >5 cm) at trial entry. Patients received coltuximab ravtansine (55 mg/m2) in 4 weekly and 4 biweekly administrations until disease progression or unacceptable toxicity. 41 patients were eligible for inclusion in the per-protocol population. The primary endpoint, overall response rate (International Working Group criteria) in the per-protocol population, was 18/41 (43.9% [90% confidence interval 30.6-57.9%]). Median duration of response, progression-f...
