This clinical trial is focused on studying a type of cancer called relapsed or refractory diffuse large B-cell lymphoma (DLBCL). This condition occurs when the cancer returns or does not respond to treatment. The study is testing a combination of medications to see how well they work together. The medications being studied are Brentuximab Vedotin, Lenalidomide, and Rituximab. Brentuximab Vedotin is a medication that targets cancer cells, Lenalidomide is an immunomodulatory drug that helps the immune system fight cancer, and Rituximab is a monoclonal antibody that targets specific proteins on cancer cells.
The purpose of the study is to evaluate how these medications work together in treating patients with DLBCL. Participants in the study will receive either the combination of Brentuximab Vedotin, Lenalidomide, and Rituximab or a combination that includes a placebo instead of Brentuximab Vedotin. A placebo is a substance with no active medication. The study will compare the effects of these treatments over a period of time to see which is more effective in preventing the cancer from getting worse.
Throughout the study, participants will receive the medications through subcutaneous injections, which means the medication is given under the skin, and oral capsules, which are taken by mouth. The study will monitor the participants’ health and the progression of their cancer to gather information on the effectiveness and safety of the treatment combinations. The goal is to find out if the combination of these medications can help improve the outcomes for patients with relapsed or refractory DLBCL.
