Official Title: A Phase 1 Study of Blinatumomab in Combination With Checkpoint Inhibitor(s) of PD-1 (Nivolumab) or Both PD-1 (Nivolumab) and CTLA-4 (Ipilimumab) in Patients With Poor-Risk, Relapsed or Refractory CD19
Brief Summary: This phase I trial studies the side effects and best dose of blinatumomab when given with nivolumab alone or nivolumab and ipilimumab in treating patients with poor-risk CD19+ precursor B-lymphoblastic leukemia that has come back after a period of improvement or has not responded to treatment. Monoclonal antibodies, such as blinatumomab, nivolumab and ipilimumab, may interfere with the ability of tumor cells to grow and spread.
