The study is designed as an international, multicenter, open-label, two-arm, prospective phase III study to compare the treatment of polatuzumab vedotin plus rituximab, ifosfamide, carboplatin and etoposide (Pola-R-ICE) with the combination of rituximab, ifosfamide, carboplatin and etoposide (R-ICE) alone as salvage therapy in patients with primary refractory or relapsed DLBCL.~The study will involve study sites in Germany, UK, Spain, and Austria. It is planned to include 324 patients who will be randomized 1:1 to receive either treatment in the experimental arm (Pola-R-ICE) or in the standard arm (R-ICE) to end up with 308 evaluable subjects for the randomized part of the trial. Further 10 patients will be treated with Pola-R-ICE during the safety run-in phase.~The study consists of a screening/inclusion visit, three chemotherapy cycles, an end-of - treatment visit (EoT), and follow-up visits. For each subject, the total duration of the study will be approximately 3 months of treatment plus at least 21 months follow-up. The study will end when the last included patient will have passed the last follow-up visit (LPLFU). For the study as a whole, the primary outcome will be evaluated when the last included patient will have completed the 21 months follow-up period or has left the study prematurely.~For the study as a whole, the primary outcome will be evaluated when the last included patient will have completed the 21 months follow-up period or has left the study prematurely.
