Filter by:This phase I trial studies the side effects of donor stem cell transplant in treating patients with high risk acute myeloid leukemia. Giving low doses of chemotherapy before a donor peripheral blood stem cell 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 they do not exactly match the patient's blood. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect)
The purpose of this study is to determine whether cyclophosphamide post bone marrow transplant increases the rate of patients alive, in remission and without immunosuppression, one year after transplant, when compared with the combination of methotrexate and calcineurin inhibitor
The purpose of this study is to find out the highest safe dose and examine the side effects and effectiveness of eltrombopag olamine in patients with acute myeloid leukemia (AML) treated with chemotherapy that have not responded to previous therapy or have suffered a relapse
This partially randomized phase II trial studies the side effects and best way to give and best dose of cholecalciferol in treating patients with acute myeloid leukemia (AML) undergoing intensive induction chemotherapy. Cholecalciferol may help improve the outcome of patients with AML undergoing intensive chemotherapy
This phase I/II trial studies the side effects and best dose of etoposide and mitoxantrone hydrochloride when given together with cyclosporine and pravastatin sodium and to see how well they work in treating patients with relapsed or refractory acute myeloid leukemia (AML). Cyclosporine may inhibit efflux of cancer drugs out of cancer cells and may thereby improve chemotherapy treatment for AML. Pravastatin sodium may stop the growth of cancer cells by blocking some of the nutrients needed for cell growth. Drugs used in chemotherapy, such as etoposide and mitoxantrone hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving cyclosporine together with pravastatin sodium, etoposide, and mitoxantrone hydrochloride may kill more cancer cells
This phase I trial studies the best dose of azacitidine and to see how well it works with mitoxantrone hydrochloride and etoposide in treating older patients with acute myeloid leukemia that has a lower chance of responding to treatment or higher risk of returning (poor prognosis). Drugs used in chemotherapy, such as azacitidine, mitoxantrone hydrochloride, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
This phase I trial is studying the side effects and the best dose of entinostat when given together with sorafenib tosylate in treating patients with advanced or metastatic solid tumors or refractory or relapsed acute myeloid leukemia. Entinostat and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to evaluate the level of a specific protein (PTEN) in the cancer cells of chronic myelomonocytic leukemia (CMML) patients. This protein might be involved in the transformation from normal blood cells to leukemia cells. The PTEN protein has not been investigated in CMML specifically but it has been discovered in closely related cancers. If this study demonstrates an abnormality in this protein, future testing will be designed to evaluate the genetic abnormality that resulted in lack of the normal presence of this protein. The goal is that the results of this study will help to develop new drugs and strategies to treat the future patients with CMML by understanding the abnormality of the disease at the cellular and molecular levels. The results of this study can also be utilized by future studies to develop individualized treatment to patients who have abnormal levels of this protein.
This is a Phase I study designed to determine the MTD and assess the toxicity associated with clofarabine followed by fractionated cyclophosphamide in patients > 1 year of age or < 21 years of age with relapsed or refractory acute leukemias. There will be 25 to 35 patients enrolled. Cohorts of 3 to 6 patients each will receive escalated doses of clofarabine followed by fractionated cyclophosphamide until the MTD is reached. There will be no intra-patient dose escalation. Single-agent cyclophosphamide will be administered by 2-hour IVI on Day 0 of cycle 1. On Days 1, 2, and 3 and Days 8, 9, and 10 clofarabine will be administered by IVI 2 hours before each dose of cyclophosphamide (see the treatment schema below). A cycle is defined as 28 days.
Study and Dose Rationale The safety profile of clofarabine appears acceptable within the target populations studied to date in the clinical studies summarized in Section 2.3. clofarabine has demonstrated anti-cancer activity through inhibition of DNA synthesis and repair, induction of apoptosis, and possibly through other mechanisms. The effect of clofarabine on DNA methylation has not been determined. Numerous responses have been observed after treatment with clofarabine in heavily pre-treated relapsed/refractory patients with ALL or AML. Recently 2 small studies were conducted at the M.D. Anderson Cancer Center looking at the use of clofarabine in the treatment of MDS.31 The first study randomized patients in a Bayesian fashion to 15 vs. 30 mg/m2 given IV daily for 5 days every 4 to 8 weeks. In the 15 mg/m2 arm 3 of 7 patients had a complete remission according to the International Working Group (IWG)32 criteria for response. In the 30 mg/m2 arm, 2 of 6 patients had a complete remission while 1 patient had hematologic improvement according to IWG criteria. In the second study, patients were treated with oral clofarabine at a dose of 40 mg/m2 daily for 5 days every 4 to 8 weeks. Two of 7 patients had hematologic improvement according to IWG criteria. The main toxicities in both trials were prolonged myelosuppression and liver function abnormalities. Preclinical animal models have shown increased clofarabine activity against multiple different tumors with repetitive daily dosing for prolonged periods of time.33 The use of an oral therapy is advantageous for the treatment of a chronic malignancy such as MDS. Furthermore, based on the pre-clinical data mentioned above daily repetitive dosing over a protracted period may provide increased efficacy. Since most MDS patients are elderly and may not tolerate aggressive therapy, a schedule of administration of low dose oral clofarabine over a protracted period may provide the advantage of increased efficacy without severe toxicity. The safety of a protracted daily dosage of oral clofarabine in humans has not been determined. The dosing scheme for this study will therefore include a dose escalating phase I component followed by a phase II component. The starting dose will be 5 mg (fixed dose) orally daily for 10 days. This dose will be escalated in cohorts of 3 patients as tolerated up to a maximal dose of 15 mg (fixed dose) orally for 10 consecutive days. Note that at the latter dose a patient will receive a total of 150 mg of clofarabine per cycle, which far lower than the MD Anderson study of oral clofarabine in MDS whereby patients received 200 mg/m2 per cycle. OBJECTIVES: Study Overview The purpose of this study is to determine the efficacy and toxicity of Clofarabine administered orally at a low daily dose for the treatment of myelodysplastic syndromes.
