Filter by:The goal of this clinical research study is to learn if the combination of fludarabine and cytarabine can help to control Acute Myelogenous Leukemia (AML), High-Risk Myelodysplastic Syndrome (MDS) or Chronic Myeloid Leukemia (CML) in myeloid blast crisis. The safety of this drug combination will also be studied.
The study is aimed to treat low-risk MDS patients,who are dependent on red-blood cell transfusion due to disease-related anemia, and who have a proven resistance towards treatment with erythropoetin-stimulating agents (ESA). The study randomizes patients to receive a treatment with the demethylating agent 5-azacytidine alone or in combination with an ESA. The study thus evaluates, if efficacy of 5-azacytidine, notably on the red-blood cell transfusion-dependence is comparable/inferior to a combination treatment with azacitidine and an ESA (that is if 5-azacytidine can overcome the resistance towards ESA). Being a phase II study, the study assesses, duration of erythroid response, overall survival and time to progression as well as toxicity.
RATIONALE: Studying samples of bone marrow and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at bone marrow and blood samples from patients with leukemia or other hematopoietic cancers.
RATIONALE: Gathering information about how often methemoglobinemia occurs in young patients receiving dapsone for hematologic cancer or aplastic anemia may help doctors learn more about the disease and plan the best treatment. PURPOSE: This research study is looking at methemoglobinemia in young patients with hematologic cancer or aplastic anemia treated with dapsone.
This is an open-label, single arm study. Approximately 3-30 patients will be enrolled. Patients will receive Oral ciclopirox olamine (aqueous suspension), initial starting dose of 5 mg/m2/day administered as a single dose daily for 5 days. Three patients will initially be treated at each dose level in sequential cohorts. Dose escalation will continue for each subsequent cohort based on toxicity and plasma drug concentrations observed during the previous cohort. Dose escalation will continue until establishment of the maximum tolerated dose (MTD) has been met. Patients who have demonstrated response to treatment, up to 6 total cycles of treatment may be administered. If additional cycles are warranted, ciclopirox olamine will be given at the same dose and frequency as the patient initially received.
This phase I trial studies pretargeted radioimmunotherapy and donor peripheral blood stem cell transplant employing fludarabine phosphate and total-body irradiation (TBI) to treat patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells. Radiolabeled monoclonal antibodies can be combined with fludarabine phosphate and TBI to find cancer cells and kill them without harming normal cells. Pretargeted radioimmunotherapy (PRIT) allows for further improved targeting of tumor cells over standard directly labeled antibodies.
This study is under Molecular and Cellular Characterization of Myelodysplastic Syndromes (MDS) (eProtocol 15369). The purpose of this proposed study is to analyze existing samples taken from participants participating in a clinical trial evaluating the efficacy and safety of investigational agent ON 01910.Na (eProtocol 16214). This study will use existing blood and marrow samples to determine the rate and duration of objective hematologic and marrow responses, and duration of progression-free survival in ON01910.Na-treated MDS patients. This study will use existing blood and marrow samples to determine the rate and duration of objective hematologic and marrow responses, and duration of progression-free survival in ON01910.Na-treated MDS patients.
This is a genetic disease (transmitted through the parents' genes) called Fanconi Anemia. Because of that genetic disease, the bone marrow has changed and now has failed, or has given rise to a preleukemia called myelodysplastic syndrome (MDS) or leukemia (acute myelogenous leukemia or AML). Without treatment these complications of Fanconia anemia (FA) are fatal. The only treatment that can cure these complications is an allogeneic transplant of stem cells, meaning, giving the patient bone marrow cells from a healthy donor that can produce normal blood cells that will replace the bone marrow that is sick. What has been given for the treatment of FA in the past is to use a combination of low doses of radiation to the whole body (total body irradiation) and low doses of the chemotherapy drugs (cyclophosphamide and fludarabine) before the transplant. However, the use of radiation can, later on, increase the chances of getting a second cancer of the skin, head or the neck. These chances of a second cancer are higher than normal in patients with FA. The purpose of this study is to find out if the doctors can do the same thing with the same chemotherapy drugs used in the past. However physicians will use another chemotherapy drug called busulfan instead of the radiation. The goal of this study is to get rid of the short term and long term risks of the radiation. The first new part of this treatment will be to replace drugs for radiation with chemotherapy drugs.
Primary: To determine the maximum tolerated dose and schedule of decitabine when administered as maintenance therapy after allogeneic hematopoietic stem cell transplantation (alloHSCT) performed for AML or high-risk MDS.
Primary objectives: - To determine the maximum tolerated dose (MTD) of SAR103168 and to characterize the dose limiting toxicities (DLTs) in the proposed dose regimen - To evaluate the pharmacokinetic (PK) profile of SAR103168 Secondary objectives: - To characterize the global safety profile of SAR103168 - To evaluate preliminary anti-leukemia activity - To investigate the potential induction effect on CYP3A4 and persistence of this effect by using oral midazolam as a probe substrate in patients enrolled into the expanded cohort at the MTD - To determine the metabolic pathways of SAR103168 and identify the chemical structures of metabolites - To determine the potential impact of SAR103168 on the QTc interval in patients enrolled at the MTD
