Active clinical trials for "Leukemia"

The primary objectives of this study are to determine the maximum tolerated dose (MTD) or optimal biologic dose (OBD) and safety profile of CAT-8015 in participants with relapsed or refractory advanced B-cell NHL (diffuse large B-cell lymphoma [DLBCL], follicular lymphoma [FL], mantle cell lymphoma [MCL]) or CLL.

This is a Pilot/Phase I, single arm, single center, open label study to determine the safety, efficacy and cellular kinetics of CART19 (CTL019) in chemotherapy resistant or refractory CD19+ leukemia and lymphoma subjects. The study consists of three Phases: 1) a Screening Phase, followed by 2) an Intervention/Treatment Phase consisting of apheresis, lymphodepleting chemotherapy (determined by the Investigator and based on subject's disease burden and histology, as well as on the prior chemotherapy history received), infusions of CTL019, tumor collection by bone marrow aspiration or lymph node biopsy (optional, depending on availability), and 3) a Follow-up Phase. The suitability of subjects' T cells for CTL019 manufacturing was determined at study entry. Subjects with adequate T cells were leukapheresed to obtain large numbers of peripheral blood mononuclear cells for CTL019 manufacturing. The T cells were purified from the peripheral blood mononuclear cells, transduced with TCR-ζ/4-1BB lentiviral vector, expanded in vitro and then frozen for future administration. The number of subjects who had inadequate T cell collections, expansion or manufacturing compared to the number of subjects who had T cells successfully manufactured is a primary measure of feasibility of this study. Unless contraindicated and medically not advisable based on previous chemotherapy, subjects were given conditioning chemotherapy prior to CTL019 infusion. The chemotherapy was completed 1 to 4 days before the planned infusion of the first dose of CTL019. Up to 20 evaluable subjects with CD19+ leukemia or lymphoma were planned to be dosed with CTL019. A single dose of CTL019 (consisting of approximately 5x10^9 total cells, with a minimal acceptable dose for infusion of 1.5x10^7 CTL019 cells) was to be given to subjects as fractions (10%, 30% and 60% of the total dose) on Day 0, 1 and 2. A second 100% dose of CTL019 was initially permitted to be given on Day 11 to 14 to subjects, providing they had adequate tolerance to the first dose and sufficient CTL019 was manufactured.

RATIONALE: Giving low doses of chemotherapy before a donor 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. Also, monoclonal antibodies, such as rituximab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal 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 tacrolimus, sirolimus, and methotrexate after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor stem cell transplant works in treating patients with high-risk chronic lymphocytic leukemia or small lymphocytic lymphoma.

The goal of this clinical research study is to learn the most tolerable dose of Nexavarâ (sorafenib) when given in combination with Mobozilâ (plerixafor) and Neupogenâ (filgrastim) to patients with AML. The safety of this combination will also be studied. Funding Source - FDA OOPD

The goal of this clinical research study is to learn the amount of posaconazole that is in the body at different time points when given to patients with leukemia. The safety of this drug will also be studied. Objectives: Primary: To study the plasma pharmacokinetics of posaconazole in patients with newly diagnosed acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS) undergoing induction chemotherapy or relapsed or refractory patients who will receive salvage chemotherapy. Secondary: To evaluate the safety of posaconazole given as prophylaxis.

Prospective, multicenter, uncontrolled cohort study to analyze the efficacy of a risk adapted treatment strategy, including gemtuzumab ozogamicin (GO) during consolidation, for patients with acute myeloid leukemia (AML).

RATIONALE: Drugs used in chemotherapy, such as cladribine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving cladribine and cytarabine together with imatinib mesylate may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of imatinib mesylate when given together with cladribine and cytarabine in treating patients with refractory or relapsed acute myeloid leukemia or blastic phase chronic myelogenous leukemia.

The goal of this clinical research study is to learn if using a combination of fludarabine, cyclophosphamide, and mitoxantrone plus rituximab, with the growth factor pegylated filgrastim, will improve the response to treatment, and increase the time this response lasts, for patients with previously untreated CLL. The safety of this combination will also be studied.

The aim of this phase II trial is asses the tolerability and the effectiveness of imatinib in patients with chronic myelogenous leukemia in chronic phase who are in relapse after stem cell transplantation.

The aim of this phase II trial is asses the tolerability and the effectiveness of imatinib in patients with chronic myelogenous leukemia in chronic phase with age more than 70, diagnosis of cml is being performed within 1 year. Quality of life will be carefully assessed.
