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.

PRIMARY OBJECTIVE:
I. To determine the efficacy of CB-derived allogeneic anti-CD70-CAR-IL-15-transduced cord blood-derived natural killer cells (CD70.CAR NK) cell therapy in patients with primary refractory or early relapsed DLBCL and HL, as determined by the 2-year event-free survival rate.
SECONDARY OBJECTIVES:
I. To determine the antitumor activity of CB-derived CD70.CAR NK cells, as determined by the response rate (ORR) and complete response (CR) rate.
II. To establish the safety of this treatment.
III. To quantify the persistence of infused CB-derived CD70.CAR NK cells in the peripheral blood.
IV. To conduct comprehensive immune studies by evaluating tissue and blood-based biomarkers associated with response and resistance to CD70.CAR NK cells.
OUTLINE:
Patients receive lymphodepleting chemotherapy consisting of fludarabine intravenously (IV) and cyclophosphamide IV on days -5 to -3. Patients then receive CD70.CAR NK cells IV on day 0 in the absence of disease progression or unacceptable toxicity. Around day +28, patients undergo positron emission tomography (PET)/computed tomography (CT) and bone marrow aspiration and biopsy (if clinically indicated). Patients in CR or partial response (PR) undergo observation, patients with no response are considered for a second cycle of lymphodepleting chemotherapy and CD70.CAR NK cells. Around day +90, patients undergo a second PET/CT. Patients in CR undergo observation, patients with active disease are considered for a second cycle of lymphodepleting chemotherapy and CD70.CAR NK cells. Additionally, patients undergo CT, chest radiography (x-ray), and echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening. Patients also undergo PET/CT, bone marrow aspiration and biopsy (if clinically indicated), and blood sample collection throughout the study.
After completion of study treatment, patients are followed up at days 7, 14, 28, and 56, months 3, 6, 9, 12, 15, 18, 21, and 24.
