Active clinical trials for "Leukemia, Myelomonocytic, Chronic"

A Phase 3, randomized, open-label, parallel-group, multicenter study designed to evaluate the efficacy and safety of guadecitabine in participants with MDS or CMML who failed or relapsed after adequate prior treatment with azacitidine, decitabine, or both. This global study will be conducted in approximately 15 countries. Approximately 408 participants from approximately 100 study centers will be randomly assigned in a 2:1 ratio to either guadecitabine (approximately 272 participants) or Treatment Choice (approximately 136 participants). The study consists of a 21-day screening period, a treatment period, a safety follow-up visit, and a long-term follow-up period. The study is expected to last more than 2 years, and the duration of individual participant participation will vary. Participants may continue to receive treatment for as long as they continue to benefit.

The study will evaluate the safety, tolerability and pharmacokinetics of NEX-18a, a long-acting injectable azacitidine, in patients diagnosed with intermediate 2 or higher-risk MDS, CMML, or AML and already on treatment with azacitidine.

Background: One way to treat certain cancers of the blood and immune system is to give a patient stem cells from the bone marrow of a donor whose genes are very similar but not identical to the patients. One problem with these transplants is that the new immune cells may not work as well in the recipient as they did in the donor. The result may be that the immune system will not work as well. This can increase the risk of severe infections and other complications. Researchers are studying the use of drugs that lower hormone levels and may allow the immune system to recover in a way that improves white blood cell function. In this study they will be looking at the drug leuprolide, a drug that lowers estrogen or testosterone levels, to see if it might improve the function of the newly transplanted cells. Objectives: To determine whether leuprolide improves immune system function after bone marrow transplant from a donor with similarities in their immune cells (matched to each other). To evaluate the effectiveness of a nuclear medicine test with a radiotracer drug 3-deoxy-3 18F-fluorothymidine (FLT) in imaging studies. FLT will be used to image the immune system function in patients who have received bone marrow from the donor. Eligibility: People between 15 (or as young as 9 in those who have gone through puberty) and 55 years of age. These patients must have acute myelogenous leukemia, acute lymphocytic leukemia, high-risk myelodysplastic syndrome, chronic myelomonocytic leukemia, or chronic myeloid leukemia. They must also be eligible for a bone marrow transplant. Genetically similar donors for the patients who are eligible for a transplant. Design: People taking part in the study will be screened with a physical examination, medical history, blood and urine tests, and imaging studies. Patients who are not in remission or who require a bone marrow donor search may receive chemotherapy first. Donors will provide bone marrow for transplant according to standard bone marrow transplant (BMT) procedures. All women and half of the men will receive regular leuprolide doses 2 weeks before BMT to suppress hormone function. All recipients will receive 4 days of radiation followed by 2-4 days of chemotherapy before the bone marrow transplant (depending on age). Recipients will also receive other drugs to prevent transplant rejection and other complications of transplantation. Recipients will be monitored in the hospital for 4 weeks after transplant with blood tests and other studies. Some recipients will have an imaging study with FLT during the protocol. These imaging studies will take place before the transplant, on days 5 and 28 after transplant, and at a later time to be determined by the study researchers. Following discharge, participants will be monitored closely for up to 6 months, with regular but less frequent followup visits for at least 5 years. Study-related medications, including vaccinations for the new immune system, will be provided by the National Institutes of Health during the hospital stay and after discharge.

The purpose of this research study is to compare the survival rates of patients with better risk disease undergoing hematopoietic stem cell transplant (HSCT) to the survival rates reported in the medical literature of similar patients undergoing reduced intensity HSCT from matched related donors.

This phase II trial is studying how well giving clofarabine and cytarabine together with filgrastim works in treating patients with newly diagnosed acute myeloid leukemia (AML), advanced myelodysplastic syndrome (MDS), and/or advanced myeloproliferative neoplasm. Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving the drugs in different doses may kill more cancer cells. Colony stimulating factors, such as filgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy.

RATIONALE: Giving chemotherapy before a donor umbilical cord blood transplant (UCBT) helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from an unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood stem cell transplant works in treating patients with hematologic malignancies.

Azacitidine has proved prolonged overall survival in patients with high-risk MDS. Minor pilot studies have shown that treatment with Azacitidine can induce transfusion independency in previous transfusion dependent patients with low-risk MDS. This study will evaluate the effect of Azacitidine in transfusion dependent patients with low-risk MDS (IPSS low or int-1) or low risk CMML. Included patients should first have failed, or considered not being eligible to, treatment with EPO +/- G-CSF. Our hypothesis is that Azacitidine can lead to transfusion independency in this group of patients. Those patients who do not respond to treatment with Azacitidine alone, will be given treatment with the combination of Azacitidine and EPO where our hypothesis is that Azacitidine can restore sensitivity to EPO.

This randomized phase II trial studies azacitidine with or without entinostat to see how well they work compared to azacitidine alone in treating patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, 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. Entinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine together with entinostat may work better in treating patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia.

This phase II trial studies the side effects and best dose of total-body irradiation when given together with fludarabine phosphate followed by a donor peripheral stem cell transplant in treating patients with myelodysplastic syndromes (MDS) or myeloproliferative disorders (MPD). Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
