RecruitingPhase 1Drug trialAsciminib Maintenance Therapy Following alloHCT or CAR T to Prevent Relapse in Adults With Ph+ALLThe purpose of the study is to see if a study drug called asciminib is safe and okay for people to take after they've had treatment for a type of blood cancer called Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia (Ph+ B-ALL). We're looking at two groups of adults: one group had an Allogeneic Stem Cell Transplant (alloHCT) cohort A, and the other group had chimeric antigen receptor T cell (CAR T) therapy, cohort B. We also want to figure out what the best dose of asciminib is to use moving forward in future studies.
