CD70.CAR NK Cells for the Treatment of Primary Refractory or Early Relapsed Diffuse Large B-Cell Lymphoma and Hodgkin Lymphoma

Trial Status: approved

This phase II trial studies how well CD70.chimeric antigen receptor (CAR) natural killer (NK) cells work in treating patients with diffuse large B-cell lymphoma (DLBCL) and Hodgkin lymphoma (HL) that does not respond to frontline treatment (primary refractory) or that has come back within 12 months of improvement (early relapsed). NK cells are a type of immune cell that attack and kill foreign or cancerous cells. CD70.CAR NK cells are obtained from donated umbilical cord blood (CB). The NK cells are separated from the donor CB and are changed in the laboratory so they will attack cancer cells. Before the CD70.CAR NK cells can be administered, lymphodepleting chemotherapy, such as fludarabine and cyclophosphamide, is given. Giving lymphodepleting chemotherapy before CD70.CAR NK cells helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. Following lymphodepleting chemotherapy, the CD70.CAR NK cells are infused into the patient, which may help attack and kill any remaining cancer cells. CD70.CAR NK cells may be effective in treating patients with primary refractory or early relapsed DLBCL and HL.
