Study Investigating the Efficacy of the Addition of Crenolanib to Chemotherapy vs Chemotherapy Alone in Patients With R/R FLT3 Mutated AML

This is a multi-center, randomized, trial to evaluate the efficacy of adding crenolanib to salvage chemotherapy versus salvage chemotherapy alone in subjects with relapsed/refractory FLT3-mutant AML. Approximately 320 subjects will be randomized 1:1 to receive either salvage chemotherapy (HAM or FLAG-Ida) with crenolanib (treatment arm 1) or salvage chemotherapy (HAM or FLAG-Ida) alone (treatment arm 2).
