This clinical trial is focused on studying a type of cancer called Diffuse Large B-Cell Lymphoma (DLBCL), specifically a high-grade form with certain genetic changes known as MYC and BCL2 and/or BCL6 rearrangements. The study aims to evaluate the effectiveness of a treatment regimen called DA-EPOCH-R, which includes a combination of medications: Rituximab, Doxorubicin Hydrochloride, Vincristine Sulfate, Cyclophosphamide, Etoposide, and Prednisolone. After this initial treatment, patients will receive a medication called Nivolumab (also known by its code name BMS936558) as a follow-up treatment to help prevent the cancer from returning.
The purpose of the study is to see if adding Nivolumab after the initial treatment can improve the chances of the cancer not coming back within 12 months. Participants will first receive the DA-EPOCH-R treatment, which involves a series of medications given through an infusion into a vein, and Prednisolone taken as a tablet. This phase lasts for about 18 weeks. After completing this phase, patients will receive Nivolumab infusions for up to 52 weeks. Some participants may receive a placebo instead of Nivolumab to compare the outcomes.
The study will monitor the participants’ health and response to the treatment through regular check-ups and imaging tests like PET-CT scans, which help visualize the cancer’s activity in the body. The goal is to determine if the combination of treatments can increase the time patients remain free of cancer. This study is important for understanding how to better treat this aggressive form of lymphoma and improve patient outcomes.
