Modified Immune Cells (AFM13-NK) and A Monoclonal Antibody (AFM13) in Treating Patients With Recurrent or Refractory CD30 Positive Hodgkin or Non-Hodgkin Lymphomas

PRIMARY OBJECTIVE: I. To establish the safety and recommended phase II dose of umbilical cord blood (CB)-derived natural killer (NK) cells preloaded with the bispecific antibody AFM13 (AFM13-NK), followed by intravenous anti-CD30/CD16A monoclonal antibody AFM13 (AFM13) in patients with refractory/relapsed CD30-positive lymphoid malignancies based on incidence of dose limiting toxicities (DLTs) per dose level. (Phase I) II. To assess the activity of umbilical cord blood (CB)-derived natural killer (NK) cells preloaded with the bispecific antibody AFM13 (AFM13- NK), followed by intravenous AFM13 in patients with refractory/relapsed CD30-positive lymphoid malignancies. based on overall response rate (ORR), complete response (CR) rate and partial response (PR) rate. (Phase II) SECONDARY OBJECTIVES: I. To evaluate the duration of response. II. To evaluate the event-free survival (EFS) rate. III. To evaluate the overall survival (OS) time. IV. To quantify the persistence of infused donor CB AFM13-NK cells in the recipient. V. To conduct comprehensive immune reconstitution studies. OUTLINE: This is a dose-escalation study of AFM13-NK. Patients receive standard of care fludarabine intravenously (IV) over 1 hour and standard of care cyclophosphamide IV over 30-60 minutes on days -5 to -3, AFM13-NK IV over 4 hours on day 0, and then AFM13 IV over 4 hours on days 7, 14, and 21. After completion of study treatment, patients are followed up at 28 days, 8 weeks, 100 and 180 days and then every 3-6 months for 2 years.
