Daniel DeAngelo, MD, PhD, Dana-Farber Cancer Institute, Boston, MA, discusses the phase 1 study (NCT02081378) of asciminib plus dasatinib and prednisone for untreated BCR-ABL1 positive acute lymphoblastic leukemia (ALL) in older adults. Dual ABL1 kinase inhibition with these agents was promising, and an expansion cohort is planned to further characterize safety and clinical activity of the combination.
