Testing Pembrolizumab with Existing Cancer Therapy in Patients with Evidence of Residual Chronic Myelogenous Leukemia
This phase II trial studies how well pembrolizumab and dasatinib, imatinib mesylate, nilotinib, or bosutinib work in treating patients with chronic myeloid leukemia and persistent detection of minimal residual disease, defined as the levels of a gene product called bcr-abl in the blood. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the bodys immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Dasatinib, imatinib mesylate, nilotinib, and bosutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and dasatinib, imatinib mesylate, nilotinib, or bosutinib may work better in treating patients with chronic myeloid leukemia compared to dasatinib, imatinib mesylate, nilotinib, or bosutinib alone.
Imatinib Mesylate and Combination Chemotherapy in Treating Patients with Newly Diagnosed Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia
Multiple Cancer Types
This randomized phase III trial studies how well imatinib mesylate works in combination with two different chemotherapy regimens in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). Imatinib mesylate has been shown to improve outcomes in children and adolescents with Philadelphia chromosome positive (Ph+) ALL when given with strong chemotherapy, but the combination has many side effects. This trial is testing whether a different chemotherapy regimen may work as well as the stronger one but have fewer side effects when given with imatinib. The trial is also testing how well the combination of chemotherapy and imatinib works in another group of patients with a type of ALL that is similar to Ph+ ALL. This type of ALL is called ABL-class fusion positive ALL", and because it is similar to Ph+ ALL, is thought it will respond well to the combination of agents used to treat Ph+ ALL.
