Detailed Description
PRIMARY OBJECTIVES:
I. Evaluate the safety of asciminib maintenance in adults with Philadelphia chromosome (Ph)+ acute lymphoblastic leukemia (ALL) in morphological complete remission (CR) post hematopoietic stem cell transplantation (HSCT; Arm 1) or chimeric antigen receptor (CAR) T cell therapy (Arm 2).
II. Determine the recommended phase 2 dosing (RP2D) of asciminib maintenance post cellular therapies in Ph+ ALL in each arm.
SECONDARY OBJECTIVES:
I. Evaluate feasibility of asciminib maintenance measured as the number of patients who continue asciminib > 3 cycles post cellular therapy.
II. Duration of response. III. Timing for minimal residual disease (MRD) and full relapse. IV. Relapse free survival at 1 year post cellular therapy. V. Overall survival at 1 year post cellular therapy. VI. Non-relapse mortality at 1 year post cellular therapy. VII. Relapse at 1 year post cellular therapy. VIII. Rates of asciminib discontinuation and interruption due to toxicity at 1 year post cellular therapy.
IX. Rate of switching to another tyrosine kinase inhibitor (TKI) at 1 year post cellular therapy X. Rate and grade of acute graft-versus-host disease (GVHD) at 180 days post initiation of asciminib maintenance post HSCT. (Arm 1) XI. Rate and grade of chronic GVHD at 1 year post initiation of asciminib maintenance post HSCT. (Arm 1) XII. GVHD-free, relapse-free survival (GRFS) at 1 year post HSCT. (Arm 1)
EXPLORATORY OBJECTIVES:
I. For patients who are MRD-negative, evaluate MRD relapse by clonoSEQ during therapy.
II. Evaluate immune cell populations and immune reconstitution post-transplant during asciminib therapy.
III. Evaluate the impact of prevalent BCR-ABL mutations and treatment emergent BCR-ABL mutations.
IV. Evaluate B-cell aplasia and CAR T cell persistence during asciminib therapy. (Arm 2) V. Quality of life assessments using Patient Reported Outcomes Measurement Information System (PROMIS).
OUTLINE: This is a dose-escalation study of asciminib followed by a dose-expansion study.
Patients receive asciminib orally (PO) once daily (QD) or twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo echocardiography during screening and as clinically indicated, and bone marrow biopsy, bone marrow aspirate and blood sample collection throughout the study.
After completion of study treatment, patients are followed up at 30 days then every 3 months for 1 year.
