Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

The purpose of this study is to determine if lenalidomide (Revlimid®) is safe and effective as a maintenance therapy at improving further the quality of the response you achieved with your last therapy and at prolonging the duration of your response. This study will compare the effects (good and bad) of lenalidomide with the dummy drug.

The study is a Phase 1b open label, non-randomized, single institution clinical trial that is designed to evaluate the safety and tolerability of three repeat infusions of ISF35 followed by a standard regimen of three cycles of fludarabine, cyclophosphamide and rituximab (FCR) in subjects with refractory, resistant, and/or 17p- CLL.

The study is a Phase I, dose-escalating, non-randomized, single institution clinical trial assessing the safety and efficacy of autologous Ad-ISF35-transduced CLL B cells administered as a single intravenous infusion in patients with chronic lymphocytic leukemia (CLL).

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 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.

To investigate the safety and efficacy of two dose regimes of ofatumumab in combination with chemotherapy in previously untreated patients with B-CLL

Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. This phase I trial is studying the side effects and best dose of 17-N-allylamino-17-demethoxygeldanamycin in treating patients with advanced epithelial cancer, malignant lymphoma, or sarcoma

The purposes of this study are to determine a maximum tolerated dose and to evaluate the safety and efficacy of CP-461 in patients with Chronic Lymphocytic Leukemia.
