Phase II Study of the Combination of Blinatumomab and Ponatinib in Patients With Philadelphia Chromosome (Ph)-Positive and/or BCR-ABL Positive Acute Lymphoblastic Leukemia (ALL)
M.D. Anderson Cancer Center
Summary
This phase II trial studies how well blinatumomab, methotrexate, cytarabine, and ponatinib work in treating patients with Philadelphia chromosome (Ph)-positive, or BCR-ABL positive, or acute lymphoblastic leukemia that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as blinatumomab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as methotrexate and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Ponatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab, methotrexate, cytarabine, and ponatinib may work better in treating patients with acute lymphoblastic leukemia.
Description
PRIMARY OBJECTIVES: I. To evaluate the complete molecular response rate in cohort 1 (newly diagnosed Philadelphia chromosome \[Ph-positive\] and/or BCR-ABL-positive acute lymphoblastic leukemia \[ALL\]) and the overall response (complete remission \[CR\]+CR with incomplete blood count recovery \[CRi\]) rate in cohort 2 (relapsed/refractory disease). SECONDARY OBJECTIVES: I. To evaluate other clinical efficacy endpoints (complete cytogenetic response, complete molecular response \[CMR\], event-free survival \[EFS\] and overall survival \[OS\]) and safety of the regimen. EXPLORATORY OBJECTIV…

Inclusion Criteria: 1. Diagnosis of one of the following: 1. Participants ≥ 18 years of age with previously untreated Ph-positive ALL \[either t(9;22) and/or BCR-ABL positive\] (includes patients initiated on first course of therapy before cytogenetics known) or with lymphoid accelerated or blast phase CML. These participants could have received one or two courses of chemotherapy with or without other TKIs and still eligible. (Participants with lymphoid accelerated or blast phase CML will be evaluated separately) i. If they achieved CR, they are assessable only for event-free and overall…
