Filter by:The purpose of this study is to compare outcome of high risk myelodysplasia patients aged from 50 to 70 years with or without HLA compatible (9 or 10 identities / 10) donor. High risk myelodysplasia includes IPSS intermediate 2 and high myelodysplasia and patients with sever thrombocytopenia. Patients are registered when they acquire risk factors.
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.
The purpose of this study is to compare the effects (good and bad) of the medication basiliximab in combination with cyclosporine (investigational therapy) for the prevention of a complication of bone marrow transplantation known as graft-versus-host disease (GVHD). GVHD is a complication in which the cells of the transplanted bone marrow react against organs and tissues.
This is an open-label, single arm phase 1 study to evaluate the dose-limiting toxicity, maximum tolerated dose, and recommended phase II dose of Clioquinol in patients with relapsed or refractory hematologic malignancies. The study will also characterize Cliquinol's safety, tolerability and pharmacodynamic effect.
As one of the nation's largest cooperative cancer treatment groups, the Alliance for Clinical Trials in Oncology (Alliance) is in a unique position to organize a Leukemia Tissue Bank. The member institutions diagnose hundreds of patients with leukemia or myelodysplastic syndrome each year, and uniformly treat these patients with chemotherapy regimens. The Alliance offers centralized data management for the clinical history, the classification of the leukemia and myelodysplastic syndrome, cytogenetics, flow cytometric analysis, treatment and follow-up. The highly skilled health care providers at each member institution are familiar with obtaining informed consent, completing data questionnaires and shipping specimens. There currently exists a central processing facility where samples are prepared for a variety of cellular and molecular studies. Hence, the patient resources, the health care providers, and a processing facility for a Leukemia Tissue Bank are all in place. What is needed, however, and is addressed in the current protocol, is a formal mechanism to procure bone marrow, blood and normal tissue from patients with hematologic malignancies who are to be enrolled on Alliance (Cancer and Leukemia Group B [CALGB]) treatment studies.
The main purpose of this trial is to study whether the drug sitagliptin can be given safely to patients undergoing umbilical cord blood transplantation to speed up engraftment (recovery of blood counts after transplant).
This is a phase II trial of reduced intensity conditioning with Bu/Flu/ATG in pediatric patients with hematologic malignancies at high risk for transplant related mortality with standard transplantation. Patients qualify based on organ system dysfunction, active but stable infection, history of previous transplant or late stage disease. We plan to enroll 45 patients through the Pediatric Blood and Marrow Transplant Consortium (PBMTC) and anticipate that the outcome of the trial will pave the way for phase II or III disease specific protocols addressing efficacy of the approach compared to standard transplant approaches in better risk patients.
This study will determine the activity of decitabine, low dose cytarabine (ARA-C) and G-CSF for patients with myelodysplasia and leukemia.
Results to date of umbilical cord blood transplantation in adult and fully mature adolescent patients are inferior to what is seen in children, due to a lower stem cell dosage in adults and a more toxic conditioning regimen. This phase 1 protocol will use a potentially less toxic bone marrow conditioning regimen, followed by infusion of a combined umbilical cord blood graft that will provide the patient with a higher stem cell dose than can be given with a single umbilical cord blood infusion. The subjects will be conditioned with a total body irradiation (TBI) 13.5 Gy and fludarabine. Following conditioning, up to two unrelated, partially matched umbilical cord blood grafts will be infused that will provide a minimum nucleated cell dose of 3 x 10e7/kg . The primary objective of this study is to measure the frequency of treatment-related toxicity and engraftment.
The central hypothesis of this study is that use of a less toxic chemotherapy preparative regimen for allogeneic hematopoietic stem cell transplantation in combination with T cell depletion with alemtuzumab for patients with high risk hematologic malignancies will allow effective control of disease and improved disease free and overall survival compared with historical expectations. Specifically, the objectives are to estimate toxicity, disease free, progression free, event free, and overall survival rates in patients treated with alemtuzumab T cell depleted, reduced intensity preparative regimen followed by allogeneic hematopoietic transplantation; evaluate immune recovery following this reduced intensity allogeneic immunotherapy; develop an in vitro assay to allow patient individualized targeted dosing.
