Active clinical trials for "Preleukemia"

The goal of this clinical research study is to learn if giving busulfan in a dose based on blood levels, along with a fixed (unchanging) dose of fludarabine, is more effective and causes fewer side effects for AML or myelodysplastic syndrome patients than the standard method of giving a fixed busulfan dose based on body size, along with a fixed dose of fludarabine. The safety of dosing based on blood levels will also be studied.

This is an open label extension study of romiplostim for treatment of thrombocytopenia (platelet count ≤ 50 x 10^9/L) in MDS subjects. The study is designed to assess the long-term safety of treatment with romiplostim, as measured by incidence of overall adverse events, the incidence of bleeding events, the utilization of platelet transfusions, and the duration of platelet response. The study will further describe the time to disease progression to acute myeloid leukemia (AML) and survival.

RATIONALE: Giving high doses of chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor 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 cyclosporine, methylprednisolone, and methotrexate after transplant may stop this from happening. PURPOSE: This clinical trial studies high-dose busulfan and high-dose cyclophosphamide followed by donor bone marrow transplant in treating patients with leukemia, myelodysplastic syndrome, multiple myeloma, or recurrent Hodgkin or Non-Hodgkin lymphoma.

This phase I trial studies the side effects and best dose of lenalidomide when given together with cytarabine and idarubicin in treating patients with acute myeloid leukemia. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as cytarabine and idarubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with cytarabine and idarubicin may kill more cancer cells.

The purpose of this research is to evaluate the use of lenalidomide and prednisone in people with Myelodysplastic Syndrome (MDS). Lenalidomide is a drug that alters the immune system and it may also interfere with the development of tiny blood vessels that help support tumor growth. Therefore, in theory, it may reduce or prevent the growth of cancer cells. Lenalidomide is approved by the U.S. Food and Drug Administration (FDA) for the treatment of specific types of myelodysplastic syndrome (MDS) and in combination with dexamethasone for people with multiple myeloma (MM) who have received at least 1 prior therapy. MDS and MM are cancers of the blood. It is currently being tested in a variety of cancer conditions. As it is being used in this study it is considered an investigational use. An "investigational use" is a use that is being tested and is not approved by the FDA. Prednisone is approved by the FDA to treat numerous conditions. In addition, prednisone is approved by the FDA to treat Low or Intermediate-1 IPSS Risk, non-del (5q) MDS. "Study drug" refers to the combination of lenalidomide and prednisone.

The goal of Phase 1 of this clinical research study is to find the highest tolerable dose of lenalidomide that can be given in combination with azacitidine to patients with MDS or AML. The goal of Phase 2 of this study is to learn if the combination dose of azacitidine and lenalidomide found in Phase 1 can help to control MDS and/or AML. The safety of this drug combination will be studied in both Phases.

Allogeneic stem cell transplantation (AlloSCT) followed by targeted immune therapy Gemtuzumab Ozogamicin patients with acute myeloid leukemia (AML)/juvenile myelomonocytic leukemia (JMML)/myelodysplastic syndromes (MDS) will be safe and well tolerated.

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 determine the response rate of the combination of bortezomib and melphalan in patients with Acute Myelogenous Leukemia (AML) or high-risk Myelodysplastic Syndromes (MDS).

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.
