PTLD can happen after an organ or stem cell transplant. The study is for patients whose PTLD has not been treated before and is CD20-positive, a specific marker found on the cancer cells. Researchers want to see if this combination is safe and works well, potentially helping patients avoid harsher chemotherapy.
