3 Clinical Trials for Various Conditions
This partially randomized phase III trial studies the side effects of different combinations of risk-adapted chemotherapy regimens and how well they work in treating younger patients with newly diagnosed standard-risk acute lymphoblastic leukemia or B-lineage lymphoblastic lymphoma that is found only in the tissue or organ where it began (localized). Drugs used in chemotherapy 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. Giving more than one drug (combination chemotherapy), giving the drugs in different doses, and giving the drugs in different combinations may kill more cancer cells.
This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving dasatinib together with combination chemotherapy may kill more cancer cells.
This phase II trial is studying how well fludarabine phosphate and total-body irradiation followed by donor peripheral blood stem cell transplant work in treating patients with acute lymphoblastic leukemia or chronic myelogenous leukemia that has responded to previous treatment with imatinib mesylate, dasatinib, or nilotinib. Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body irradiation (TBI) before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving mycophenolate mofetil and cyclosporine after the transplant may stop this from happening.
