Active clinical trials for "Leukemia"

Determine the effects of escalated dose of daunorubicin in induction treatment of adult patients with acute myelogenous leukemia who are younger than 60 years of age.

In this study, the efficacy and safety of two nilotinib doses, 300 mg twice daily and 400 mg twice daily, were compared with imatinib 400 mg once daily in newly diagnosed patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP). An extension protocol was included in this study design to allow patients who did not show sufficient response to their assigned treatments the opportunity to receive imatinib 400 mg BID (option available until protocol amendment 7) or nilotinib 400 mg BID, using an abbreviated safety and efficacy assessment schedule.

Patients received oral AC220 daily for 14 days to study the side effects, tolerability and best dose for treating relapsed or refractory acute myeloid leukemia, regardless of FLT3 status.

Multicenter, open-label, study of alvocidib in previously treated chronic lymphocytic leukemia patients. Primary objective is to determine overall response rate. The secondary objectives are: to assess overall safety, to assess duration of response, progression free survival, and overall survival. Clinical benefit and pharmacokinetics parameters are also evaluated.

This study will try to improve the safety and effectiveness of stem cell transplant procedures in patients with cancers of the blood. It will use a special machine to separate immune cells (T cells) from the blood of both the donor and the patient and will use photodepletion, a laboratory procedure that selectively kills cancer cells exposed to light. These special procedures may reduce the risk of graft-versus-host-disease (GVHD), a serious complication of stem cell transplants in which the donor's immune cells destroy the patient's healthy tissues, and at the same time may permit a greater graft-versus-leukemia effect, in which the donated cells fight any residual tumor cells that might remain in the body. Patients between 18 and 75 years of age with a life-threatening disease of the bone marrow (acute or chronic leukemia, myelodysplastic syndrome, or myeloproliferative syndrome) may be eligible for this study. Candidates must have a family member who is a suitable tissue match.

This phase II clinical trial is studying how well selumetinib works in treating patients with recurrent or refractory acute myeloid leukemia. Selumetinib may stop the growth of cancer by blocking some of the enzymes needed for cell growth

The primary objective of this study (TOTXVI) is to compare the clinical benefit, the pharmacokinetics, and the pharmacodynamics of polyethylene glycol-conjugated (PEG) asparaginase given in higher dose (HD PEG) versus those of PEG-asparaginase given in conventional dose (CD PEG) during the continuation phase. This study has several secondary objectives: Therapeutic Objectives: To estimate the event-free survival and overall survival of children with ALL who are treated with risk-directed therapy. To study whether intensifying induction, including fractionated cyclophosphamide and thioguanine, in patients with day 15 MRD > 5%, will result in improved leukemia cytoreduction in this subgroup compared to TOTXV. To assess whether intensification of central nervous system (CNS)-directed intrathecal and systemic chemotherapy will improve outcome in patients at high risk of CNS relapse. Exploratory Pharmacologic Objectives: To identify pharmacogenetic, pharmacokinetic and pharmacodynamic predictors for treatment-related outcomes in the context of the systemic therapy used in the protocol. To compare the pharmacokinetics and pharmacodynamics of PEG-asparaginase given in higher dose (3,500 or 3,000 units/m2) versus those of PEG-asparaginase given in conventional dose (2,500 units/m2) in the continuation phase. Exploratory Biologic Objectives: To determine the prognostic value of levels of minimal residual disease in peripheral blood at day 8 of remission induction. To validate new markers and methods for MRD detection. To genotype natural killer (NK) cell receptors and measure their expressions at diagnosis and before reinduction, and to associate these features with treatment outcome. To identify new prognostic factors by applying new technologies to study patient material (e.g., stored plasma, serum, cerebrospinal fluid, and normal and leukemic cells). Exploratory Neuroimaging Objectives: To use quantitative MR measures (Diffusion Tensor Imaging and high resolution volumetric imaging) to assess differences in myelin and cortical thickness development in patients treated for ALL relative to healthy controls matched for age and gender. To assess the impact of folate pathway genetic polymorphisms on myelin and cortical thickness development and neurocognitive performance. To assess the impact of frontal-parietal lobe myelin and cortical thickness development on neurocognitive performance in attention, working memory, fluency, visual-spatial reasoning and processing speed.

The main aim of this study is to test the safety of acadesine in patients with B-CLL and see what effects it has on patients and their leukaemia. The study also aims to examine the way acadesine is processed by the body. The study will look at the effects of acadesine in the body and the concentration of the drug and its main by-product (ZMP) in the blood to determine the dose and the frequency of dosing that is likely to be the most effective.

RATIONALE: Giving chemotherapy before a donor stem cell transplant using stem cells that closely match the patient's stem cells, helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine, tacrolimus, and methotrexate before and after transplant may stop this from happening. PURPOSE: Natural Killer (NK) cells from the donor's bone marrow may be important in fighting leukemia. Bone marrow donors can be selected based on the type of NK cells they have, specifically the killer immunoglobulin receptor (KIR) type. This study provides information on KIR type from potential donors, which can be used in selecting the bone marrow donor. This phase II trial of unrelated donor stem cell transplant in patients with high risk AML (monosomy 7, -5/5q-, high FLT3-ITD AR, or refractory or relapsed AML) in which KIR typing of the patients and potential donors will be available to the treating transplant physician at the time of donor selection.

The purpose of this study is to determine the safety and anti-tumor effects of an experimental immunotherapy drug, called AlloStim, which is intentionally mis-matched immune cells which are designed to elicit the same anti-tumor mechanism that occurs in allogeneic bone marrow/stem cell mini-transplant (BMT) procedures, without the toxicity associated with graft vs. host disease (GVHD).
