Active clinical trials for "Leukemia, Myelogenous, Chronic, BCR-ABL Positive"

This observational study aims at assessing the tolerability and safety profiles of Ponatinib, a drug used for Chronic Myeloid Leukemia patients who are Philadelphia positive. This drug is used during the chronic phase of the disease, according to the Italian national compassionate law 648/96.

Bosutinib is a 2nd generation tyrosine kinase inhibitor that has shown promising results from first up to fourth line treatment in patients with in chronic phase of chronic myelogenous leukaemia. Most patients discontinuing the treatment with Bosutinib do so because of side effects occuring early after starting the treatment. A step in dosing scheme could improve these early toxicities. The aim of this study therefore is to demonstrate that temporary lowering of the Bosutinib dose during early treatment may help to reduce or prevent side effects while preserving efficacy.

The objective of this study is to improve medication, symptom, and disease management of patients with hematological malignancies and multiple chronic conditions (2 or more conditions in addition to cancer) through care coordination between pharmacists working in oncology practices and those working in primary care practices (Pharmacists Coordinated care Oncology Model [PCOM]). This is a pilot study in which the investigators will examine the association between outcome measures, but the study design and sample size are insufficient to quantify the impact of OAA initiation or OAA adherence on adherence to chronic medications. This pilot study and data analyses are being done in preparation for a larger, controlled study.

This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.

The current standard therapy in previously untreated adults with chronic phase (CP) of CML is imatinib and the result of long-term follow-up of IRIS study proves that imatinib for CML CP is reasonable therapy.(1, 2) However, some patients were initially diagnosed as advanced CML, accelerated phase (AP) or blastic phase (BP). Various chemotherapies were tried and were found that there were no highly effective chemotherapies for CML BP.(3-11) Imatinib in patients with these advanced CML is also disappointing because of low response rates as well as short response duration, and sudden transformation to BC is found even in initial CML CP patients. (12-17). Recent studies showed that nilotinib or dasatinib is better than imatinib in terms of rapid response and higher molecular response in newly diagnosed CML patients.(18-21) More potent bcr-abl suppression of nilotinib is supposed to be more active than imatinib even in patients with advanced CML. However, nilotinib in patients with imatinib-resistant or -intolerant CML BP showed low hematologic response and major cytogenetic response.(22, 23)

It is an open-label, randomized, multi-center study. The efficacy and safety of two flumatinib doses, 400 mg once daily and 600 mg once daily, will be compared with imatinib 400 mg once daily in newly diagnosed (within 6 months) patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP).

Trial try to assess the efficacy of dasatinib in terms of major molecular response rate at 6 months in patients with CP-CML who have achieved complete cytogenetic response without major molecular response after at least 18 months on Imatinib 400/600.

Background: Allogeneic hematopoietic stem cell transplantation (or allotransplant; donor blood stem cells) have been used with varying degrees of success as an immune therapy for blood-system cancers (leukemias, myelodysplastic syndrome, lymphomas, multiple myeloma, etc.). Some people s cancer remains active (comes back or continues to spread) after an allotransplant, while other peoples cancer disappears and they are hopefully cured. National Institutes of Health (NIH) researchers are studying the reasons for these different treatment outcomes, and trying to develop better cancer treatments for people with active cancer after allotransplant. Researchers are collecting data from people who have had allotransplants for a cancer of the blood, whether or not the cancer is in remission, and from their donors. Those with active cancers may be eligible to participate in one of several NIH studies testing treatments for active cancer after allotransplant. Objectives: To develop a systematic, comprehensive evaluation of individuals with relapsed malignant blood cancers after allotransplant (and, if available, their donors) to identify potential treatment study options To compare the immune system after allotransplant between people whose cancers are growing with people whose cancers remain in remission. To compare the immune system after cancer relapse/progression treatment between people whose cancer responds to treatment with those whose cancers continue to grow. Eligibility: Individuals whose blood system cancer grows or comes back after receiving allotransplant treatment. Individuals whose blood system cancer is responding or in remission 100 days or more after receiving allotransplant treatment. Related stem-cell donors of eligible allotransplant recipients. Design: Participants will be evaluated with a full physical examination, detailed medical history (for recipients, including a history of allotransplant treatment process, side-effects, etc.), and blood tests. Recipients will also have imaging studies, possible tissue biopsies, quality of life questionnaires/assessments, and other tests to evaluate the current state of their cancer, whether active or in remission. In some cases, it may be possible to substitute results from recent tests and/or biopsies. Healthy related donors will have apheresis to provide white blood cells for study and/or for use in potential treatment options. If stem cells would be medically helpful to a recipient, their donors might be asked to take injections of filgrastim before the apheresis procedure to stimulate the production of stem cells for collection. As feasible, all recipients will be asked to return to the NIH for detailed follow-up visits in conjunction with 6, 12, and 24 months post-allotransplant evaluations, and may be monitored between visits. Recipients whose cancers are active and who are found to be eligible for treatment protocols at the NIH will continue to be monitored on this study while participating on treatment protocols. Return visits and follow-up tests for this study will be coordinated with those required by the treatment protocol. Participants may return in the future to be evaluated for new treatment study options (recipients) or additional cell donations for therapy (donors).

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as hydroxychloroquine, may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether imatinib mesylate is more effective when given with or without hydroxychloroquine in treating patients with chronic myeloid leukemia. PURPOSE: This randomized phase II trial is studying the side effects of giving imatinib mesylate with or without hydroxychloroquine and to see how well it works in treating patients with chronic myeloid leukemia.

This study will investigate the efficacy and tolerability of a short (6 months) high dose therapy followed by a standard dose compared to a continuous treatment with a standard dose of imatinib (Glivec®) in pretreated Philadelphia chromosome- positive (Ph+)/BCR-ABL+ CML patients in chronic phase.
