This is a registrational international, multicenter, two-part open label Phase 1/2 trial in an extremely rare pediatric disease (around 17 new patients a year in US and 10 in EU). Part 1 randomizes subjects 1:1 to one of two luveltamab tazevibulin dose cohorts (1a and 1b). Part 2 further evaluates the safety and the efficacy of the selected dose. Subjects who achieve complete remission after two cycles of treatment may continue luveltamab tazevibulin as monotherapy, while non-responders at PI discretion may add luveltamab tazevibulin with standard of care (SOC) AML treatments. Luveltamab tazevibulin is given IV every two week as monotherapy and every 4 weeks when given with chemotherapy.
