This phase I trial tests the safety, side effects and best dose of asciminib as maintenance treatment for adults with Philadelphia chromosome positive acute lymphoblastic leukemia (ALL) who have undergone cellular therapies such as hematopoietic stem cell transplantation (HSCT) or chimeric antigen receptor (CAR) T cell therapy. Maintenance treatment is given to help keep cancer from coming back after it has disappeared following initial therapy. Asciminib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving asciminib may be safe and tolerable as maintenance treatment for adult patients with Philadelphia chromosome positive ALL who have undergone cellular therapies.
PRE-SCREENING: Documented informed consent of the participant and/or legally authorized representative
PRE-SCREENING: Age ≥ 18 years
PRE-SCREENING: Participant was diagnosed with Ph+ ALL according to World Health Organization criteria. The BCR::ABL1 translocation may be detected by fluorescence in situ hybridization (FISH), polymerase chain reaction (PCR), next generation sequencing (NGS), or cytogenetics at least once any time prior to cellular therapy. Participants may have p190 or p220 isoform, and participants with T315I mutation are not excluded
Arm 1: Have a date for HSCT scheduled within the next 30 days or have received HSCT within the last 30 days. Note: all HSCT donors, conditioning regimens, and GVHD prophylaxis regimens will be acceptable.
Prior treatment failure with asciminib
Treatment with strong inducers of CYP3A is not allowed and should be switched to an alternative at least 1 week prior to the start of study treatment
ARM 1: Treatment with prior HSCT is allowed
ARM 2: Treatment with prior CAR T cell therapy is allowed
