Phase 1 Study of Autologous Memory-like NK Cell Therapy With KP1237, Low Dose IL-2 in Multiple Myeloma Patients


This is an open-label single center Phase 1a/1b study with the primary objective of establishing the safety and exploring the efficacy of infusing the ex vivo combination product of cytokine induced memory-like (CIML) NK cells plus KP1237 and low dose IL-2 in newly diagnosed MM patients who have minimal residual disease (MRD+) in first remission prior to autologous stem cell transplant (ASCT).
