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

To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia accelerated phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.

This study will investigate the safety and effectiveness of a new stem cell transplant procedure for treating chronic myelogenous leukemia (CML). Transplantation of donated stem cells (cells produced by the bone marrow that mature into the different blood components-white cells, red cells and platelets) is a very effective treatment for CML. However, despite its success in a large number of patients, there is still a significant risk of death from the procedure. In addition, it results in sterility and leaves patients at increased risk for other cancers and for eye cataracts. These complications result from the intensive chemotherapy and radiation patients receive before the transplant to rid the body of cancer cells. In this study, radiation will not be used and chemotherapy drugs will be given in lower doses to try to reduce the dangers of the procedure. Patients with CML will be tested for matching with a donor (family member) and will undergo a medical history, physical examination and several tests (e.g., breathing tests, X-rays, and others) to determine eligibility for the study. Participants will then undergo apheresis to collect lymphocytes (white blood cells important in the immune system). In apheresis, whole blood is drawn through a needle in the arm, similar to donating a unit of blood. The required component-in this case, lymphocytes-are separated and removed, and the rest of the blood is returned through a needle in the other arm. Each day starting five days before the transplant, the donor will be given an injection of G-CSF, a drug that releases stem cells from the bone marrow into the blood stream. The cells will be collected after the fifth injection and again after a sixth injection the following day. Meanwhile, patients will be given cyclophosphamide and fludarabine, and perhaps anti-thymocyte globulin, to prevent rejection of the donated cells. On the day of the transplant, patients will be given cyclosporin to prevent graft-versus-host-disease, a disease in which the donor cells react against the patient's cells. They may also be given lymphocytes after the transplant to boost the immune system and destroy leukemia cells. After 30, 60 and 100 days, bone marrow cells and circulating lymphocytes will be checked to see how many are of donor cell origin. If less than 100 percent are of donor origin, more lymphocytes will be transfused. Patients will have physical examinations and blood tests at least weekly for 3 months and then periodically for 5 years.

Description: The trial is designed to determine the response of the immune system of patients with CML to a vaccine made from their own tumor. Researchers believe that this particular vaccine, which is made from purified heat shock proteins taken from each patient's tumor, alerts the body's immune system to recognize and attack invading cancer. To be considered potentially eligible for this study you must have CML in the chronic phase. Length/Duration: Vaccinations will be administered weekly for eight weeks. One clinic follow up visit will be scheduled two weeks after the final vaccination.

RATIONALE: Biological therapy may increase the number of immune cells found in bone marrow and may help a person's immune system recover from the side effects of the chemotherapy used in treating chronic myeloid leukemia. Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation, chemotherapy, and biological therapy in treating patients who have chronic myeloid leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of arsenic trioxide in treating patients who have relapsed or refractory chronic myelogenous leukemia.

Phase II trial to study the effectiveness of homoharringtonine plus low-dose cytarabine in treating patients who have newly diagnosed chronic phase chronic myelogenous leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells.

ENESTKorea is a phase 4, multi-institutional, single-arm, open-label study investigating the efficacy and safety of nilotinib at the currently approved dose (300 mg twice daily) and its exposure-outcome relationship, in adult patients diagnosed as Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase.

The purpose of this study is to characterize the pharmacokinetics of HQP1351 in participants with resistant chronic myeloid leukemia (CML) in chronic phase (CP) after high-fat and fasting meals separately（Selection of high-fat meal spectrum：《The Food - Effect Bioavailability and Fed Bioequivalence Studies》high fat diet should be 800-1000 kcal heat.).

PURPOSE: To investigate the effect of the disease and HSCT on muscle dysfunction and to investigate the prognostic role of muscle dysfunction at critical decision points in patients with hematological diseases referred to hematopoietic stem cell transplant (HSCT). HSCT: Patients diagnosed with malignant hematological diseases who are referred to myeloablative HSCT, to a myeloablative "reduced toxicity conditioning" regime with Fludarabine and Treosulfane (FluTreo) or to non-myeloablative HSCT.

The objective of this study is to determine the mass balance and routes of excretion of total radioactivity after a single oral 30mg (100µCi) dose of [14C] HQP1351 given as a suspension. For further clinical development, human mass balance data are required to elucidate the absorption, metabolism, and excretion of HQP1351.
