This trial focuses on elderly patients aged 80 years or older, or those 75 years and older who are considered frail, with untreated diffuse large B-cell lymphoma DLBCL and related lymphoma subtypes. The study is a phase III, randomized, open-label, multicenter trial conducted in several countries including Sweden, Norway, Finland, Denmark, Italy, Australia, and New Zealand. It aims to compare the standard chemotherapy regimen R-miniCHOP with an experimental treatment R-pola-miniCHP, where vincristine is replaced by polatuzumab vedotin, to assess differences in outcomes for this patient population. Participants will be randomly assigned to one of two treatment groups. One group will receive R-mini-CHOP consisting of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone over six 21-day cycles. The other group will receive R-pola-mini-CHP, which includes rituximab, cyclophosphamide, doxorubicin, prednisone, and polatuzumab vedotin instead of vincristine, also given over six 21-day cycles. Both treatments last approximately 18 weeks. The study includes a screening period lasting up to 4 weeks before treatment begins. During the study, participants will be followed for up to 36 months after completing treatment to monitor progression-free survival over two years. Researchers will evaluate disease progression and safety outcomes through regular assessments during and after the treatment period. Participants will provide informed consent and undergo evaluations including health status and disease measurements to ensure eligibility and monitor treatment effects throughout the trial.
