Filter by:This randomized phase II trial is studying how alvocidib, cytarabine, and mitoxantrone hydrochloride work compared to cytarabine and daunorubicin hydrochloride in treating patients with newly diagnosed acute myeloid leukemia. Alvocidib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine, mitoxantrone hydrochloride, and daunorubicin hydrochloride work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving alvocidib, cytarabine, and mitoxantrone hydrochloride is more effective than giving cytarabine and daunorubicin hydrochloride in treating patients with acute myeloid leukemia.
The purpose of this study is to collect clinical and laboratory data for patients affected by intermediate 1 and low risk Myelodysplastic Syndrome (MDS) associated by deletion 5q who were prescribed Revlimid from 31October 2008 to present. Revlimid is available in Italy for these patients since October 2008 based on a local disposition of the Italian Drug Agency (AIFA) issued according to a National law named 648/96.
This research is being done to learn more about nonmyeloablative bone marrow transplantation (BMT), also known as a "mini" transplant for patients with blood cancers, using bone marrow from a relative.
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.
Primary Outcome Measures: • To evaluate the efficacy of treatment with Azacitidine in patients with transfusion-dependent, low risk International Prognostic Scoring System (IPSS) 0 int-1, Myelodysplastic Syndrome (MDS) without chromosome 5 (5q) deletion. The main objective will be based on the erythroid haematologic response according to International Working Group (IWG) 2006 criteria. Secondary Outcome Measures: - Haematologic response, bases on the following parameters: platelets, and neutrophils according to International Working Group (IWG) Criteria. - Medullary and cytogenetic response according to International Working Group (IWG) 2006 criteria. - The effect of treatment response on quality of life, through the Functional Assessment of Cancer Therapy-Anemia (FACT-an) questionnaire. - Overall survival, Event-Free Survival and the Acute Leukaemia Transformation Rate.
In this study, patients will receive a myeloablative preparative regimen consisting of fludarabine and total body irradiation (TBI), followed by a T cell replete, mobilized peripheral blood stem cell (PBSC) allograft from a partially matched related donor. All patients will receive post-transplant Cy in addition to standard post transplant immunosuppression with tacrolimus and MMF. The treatment protocol will be essentially identical to the prior study, with the exception of the substitution of TBI for Busulfan. The investigators hypothesize that this change will significantly reduce the risk of HC, while maintaining the efficacy of the transplant.
This is a phase 2 single arm study in which fourteen MDS patients with Trisomy 8 or classified as Intermediate-1, 2, or High risk who meet all other inclusion/exclusion criteria will receive ON 01910.Na 1800 mg/24h as an intravenous continuous infusion (IVCI) over 72 hours every other week for the first four 2-week cycles and every 4 weeks afterwards.
A common problem after stem cell transplant is graft-versus-host-disease (GVHD). GVHD is a complication of transplantation where the donor graft attacks and damages some of your tissues. After stem cell transplant, all patients receive prophylactic medications against GVHD. In this research study, we are studying the safety and effectiveness of a bortezomib based GVHD prophylaxic drug combination in participants after myeloablative allogeneic stem call transplantation from a matched unrelated donor, mismatched related or unrelated donor.
