This is a randomised, two-arm, multicentre, open-label phase II/III efficacy and safety study of Tafasitamab in combination with BEN versus RTX in combination with BEN given to adult patients who have relapsed after or are refractory to at least one but no more than three prior systemic therapies and have failed, or are not candidates for HDC and ASCT, and have thus exhausted their therapeutic options of demonstrated clinical benefit. At least one prior therapy line must have included a CD20-targeted therapy.
The purpose of the study is to compare the safety and efficacy of Tafasitamab with BEN versus RTX with BEN in adult patients with relapsed of refractory DLBCL.
