Detailed Summary

This phase I trial studies the side effects, best dose of flotetuzumab and how well it works in treating patients with acute myeloid leukemia (AML) that has come back (recurrent) or has not responded to treatment (refractory). This study also determines the safest dose of flotetuzumab to use in children with AML. As an immunotherapy, flotetuzumab may also cause changes in the body's normal immune system, which are also under study in this trial.
