Active clinical trials for "Leukemia"

CLL dosing escalating study; daily dosing schedule; PK/PD safety

This phase II trial is studying how well tipifarnib works in treating patients with anemia or neutropenia and large granular lymphocyte leukemia. Tipifarnib may stop the growth of leukemia by blocking blood flow to the cancer cells and by blocking some of the enzymes needed for cancer cell growth.

In this ALFA-9803 trial in AML patients aged 65 years or more, we randomly compared idarubicin or daunorubicin throughout the study (first randomization) and two different post-remission strategies (second randomization): one single intensive consolidation course similar to induction versus six ambulatory cycles with one dose of idarubicin/daunorubicin (day 1) and 2x60 mg/m2/d cytarabine SC (day 1 to 5) delivered in out-patients on a monthly basis. Primary endpoint was 2-year overall survival (OS). Study hypotheses were equivalence for the idarubicin/daunorubicin comparison and a 15% difference in 2-year OS for the post-remission therapy comparison.

The purpose of this study is to determine how well subjects respond to treatment with Rituximab plus Beta-Glucan.

In this trial the investigators seek to determine if injecting cord blood cells directly into the bone marrow (intraosseous injection), rather than infusing them intravenously, can improve engraftment. The rational for doing this is that most hematopoietic stem cells (HSCs) infused intravenously never reach the bone marrow, getting trapped by other organs, such as the lungs, instead. The potential advantage of intraosseous infusion is suggested by studies in rodents that have demonstrated that in HSC transplants where the cell dose is limiting intraosseous injection is a more effective route of administration. The safety of intraosseous injections, in general, is underscored by the vast experience using intraosseous injections for resuscitation of critically ill children. The safety of injecting HSCs intraosseously has been demonstrated in a clinical trial of transplanting bone marrow cells. To safeguard against problems that might result, if intraosseous infusion fails to improve engraftment in this trial, the investigators will integrate a recently introduced strategy proven to improve engraftment-the transplantation of two cord blood units. Transplanting two unrelated cord blood units by intravenous infusion has been shown to improve engraftment (although there is still room for improvement). In this trial one unit will be injected intraosseously and the other unit will be infused intravenously. This study is being conducted as a forerunner to a larger, multi-center trial. The investigators intend to enroll five patients over 1-2 years.

This phase I trial is studying the side effects and best dose of obatoclax mesylate when given together with vincristine sulfate, doxorubicin hydrochloride, and dexrazoxane hydrochloride in treating young patients with relapsed or refractory solid tumors, lymphoma, or leukemia. Obatoclax mesylate may stop the growth of cancer cells by blocking some of the proteins needed for cell growth and causing the cells to self-destruct. Drugs used in chemotherapy, such as vincristine sulfate, doxorubicin hydrochloride, and dexrazoxane hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving obatoclax mesylate together with combination chemotherapy may kill more cancer cells.

This research trial studies multidrug resistance genes in patients with acute myeloid leukemia. Studying samples of bone marrow or blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn more about drug resistance and how patients respond to treatment.

RATIONALE: Giving chemotherapy and total-body irradiation (TBI) before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells and helps 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 will help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving colony-stimulating factors, such as filgrastim (G-CSF) and plerixafor, to the donor helps the stem cells move (mobilization) from the bone marrow to the blood so they can be collected and stored. PURPOSE: This clinical trial is studying giving plerixafor and filgrastim together for mobilization of donor peripheral blood stem cells before a peripheral blood stem cell transplant in treating patients with hematologic malignancies

RATIONALE: Allogeneic hematopoietic stem cell transplant (HSCT) is a treatment that can cure acute leukemia and myelodysplasia. After giving the patient chemotherapy and total body irradiation to stop the growth of cancer and remove the patient's diseased bone marrow, healthy stem cells from a donor are infused into the patient to replace the patient's bone marrow and make red and white blood cells and platelets. Unfortunately HSCT is often complicated by 'graft versus host disease' (GVHD) in which the transplanted cells from a donor can make an immune response against the body's normal cells and cause tissue damage and severe symptoms. Removing a subset of the donor T cells, called 'naive T cells', before transplant may reduce the frequency and intensity of GVHD. PURPOSE: This phase II trial will determine whether the removal of the naive T cells from donor cells can decrease the rate and severity of graft-vs-host disease while preserving specific immunity against infections in patients with acute leukemia or advanced myelodysplastic syndromes.

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.
