Subcutaneous Blinatumomab Plus Ponatinib for BCR-ABL+ B-ALL

Plain-language summary

B-cell acute lymphoblastic leukemia (B-ALL) is an aggressive blood cancer; about 30% of B-ALL cases in adults have a mutation called BCR-ABL that drives the disease. Blinatumomab is an antibody drug that targets B-ALL cells and helps the immune system to kill them. It is usually given intravenously, but a newer formulation can be given under the skin. Ponatinib is a drug, taken by mouth, that targets and kills leukemia cells that have the BCR-ABL mutation. The goal of this clinical trial is to test the effectiveness of treating patients with BCR-ABL positive B-ALL with blinatumomab given subcutaneously (under the skin) combined with ponatinib tablets. The study will also evaluate what side effects occur using this combination. Participants will first receive ponatinib tablets for 70 days, along with prednisone for the first month. This will be followed by blinatumomab injections 3 times per week for 4 weeks, repeated for 5 treatment cycles, along with ponatinib. Participants will then continue ponatinib tablets alone for 5 years from the start of treatment. During treatment, participants will undergo regular blood and bone marrow tests to see how well the treatment is working, and to check for side effects. The effect of this treatments on their quality of life will also be evaluated.
