This clinical trial is focused on studying a type of cancer called Hodgkin’s lymphoma, specifically in patients whose disease has not responded to initial treatment. The study will use a medication called nivolumab, which is given through an infusion into a vein. Nivolumab is a type of treatment that helps the immune system fight cancer cells. After receiving nivolumab, patients will undergo chemotherapy with three drugs: bendamustine, gemcitabine, and dexamethasone. This will be followed by a procedure called autologous bone marrow transplantation, where a patient’s own stem cells are used to help restore their bone marrow.
The purpose of this study is to evaluate how effective and safe this treatment approach is for patients with Hodgkin’s lymphoma that is resistant to previous treatments. The study will also look at the potential of using a blood test to predict how well patients might respond to the treatment. This blood test measures the amount of DNA from Hodgkin’s lymphoma cells circulating in the blood before the bone marrow transplantation.
Participants in the study will first receive nivolumab, followed by two cycles of the chemotherapy combination. Afterward, they will undergo the bone marrow transplantation. The study will monitor the patients to see how well the treatment works and to check for any side effects. The goal is to find out if this treatment can help patients achieve remission, which means the cancer is no longer detectable, and to understand how long patients can live without the disease getting worse.
