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

This is a Phase III, open-label, multicenter, randomized, comparative study of Campath versus chlorambucil as front line therapy in patients with progressive B-Cell Lymphocytic Leukemia (B-CLL). Eligible patients must have previously untreated, Rai stage I-IV disease, and be experiencing progression of their B-CLL requiring treatment. Patients who meet all eligibility criteria may be randomized on a 1:1 basis to receive either Campath or chlorambucil. An estimated 284 patients (142 per treatment arm) from approximately 40 or more investigational sites will be randomized to one of the two treatment arms.

This is a phase II trial using a non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen followed by a related or unrelated donor stem cell infusion. The primary objective is to evaluate rates of acute graft-versus-host disease (GVHD) grades II-IV and chronic GVHD with an updated GVHD prophylaxis of tacrolimus and mycophenolate mofetil (MMF) with a non-myeloablative preparative regimen in persons with hematologic malignancies.

The purpose of this study is to provide an opportunity for patients with malignancies or bone marrow failure states who lack a suitable sibling donor to undergo allogeneic hematopoietic progenitor cell transplantation using cells from unrelated individuals or cord blood registries.

This is a phase II, non-randomized, single institution study in symptomatic, previously untreated CLL patients. All patients will receive the study drug, lenalidomide, given PO daily continuously on a 28 day cycle at the starting dose level of either 2.5 mgs or 5 mgs with dose escalations to a target dose of 25mg daily. Oral dexamethasone at 12 mg PO daily will be administered on days 1-7, 14 and 21 of each cycle. Patients will be treated with lenalidomide and dexamethasone to 2 cycles past CR or to a maximum of 18 cycles, each cycle of 28 days duration. Primary endpoint is response.

B type chronic lymphocytic leukemia (B-CLL) is the most prevalent leukemia in the western world. It is a disease that occurs primarily in aging individuals and occurs more frequently in males than females. Although B-CLL was considered a homogeneous condition, recent studies by our laboratory and others suggest that B-CLL cases can be divided into two subgroups. These sub-groups can be identified by either the presence or the absence of mutations in antibody genes and/or by the percentage of B-CLL cells expressing a particular protein called CD38. These two sub-groups (unmutated antibody genes high percent CD38 and mutated antibody genes low percentage CD38) follow strikingly clinically different courses. For example, the unmutated/CD38+ group experiences a much more aggressive disease and these patients almost invariably die much sooner than the cases in the other group. In addition, the patients in the mutated CD38+ group require much more chemotherapy than mutatedlCD38-. Finally, surprisingly there is a much higher representation of males in the poor outcome unmutated CD38 group than in the better outcome group. The reasons for these differences in clinical outcome and gender bias are unknown.

This phase I trial studies the best dose and how well bendamustine works with standard chemotherapy (fludarabine, rituximab) in treating participants with lymphoid cancers undergoing stem cell transplant. Drugs used in chemotherapy, such as fludarabine, bendamustine, and rituximab, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a stem cell transplant helps stop the growth of cancer cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the participant, they may help the participant's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes, the transplanted cells from a donor can make an immune response against the body's normal cells called graft versus host disease. Giving rituximab and methotrexate after the transplant may stop this from happening.

This is a four-part dose-escalation and confirmation study in participants with advanced solid tumors. Part A is for dose escalation and determination of maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of MK-4827. Part B is a prostate/ovarian cancer cohort expansion. Part C is for a cohort of participants with relapsed or refractory T-cell prolymphocytic leukemia (T-PLL) or chronic lymphocytic leukemia (CLL). Part D will be for a cohort of participants with locally advanced or metastatic colorectal carcinoma (CRC), persistent or recurrent endometrial carcinoma, locally advanced or metastatic triple negative or highly proliferative estrogen receptor positive (ER+) breast cancer, or partially platinum-sensitive epithelial ovarian cancer. The study is also designed to find out whether MK-4827 causes at least 50% inhibition of poly adenosine diphosphate ribose polymerase (PARP) enzyme activity.

Allogeneic Non-Myeloablative Stem Cell Transplantation Using Fludarabine and Melphalan Conditioning Regimen for Chronic Lymphocytic Leukemia, Lymphoma, and Multiple Myeloma

This is a phase I - II multicenter, non-comparative, open label study in patients with previously treated CLL aimed at defining the MTD of Lenalidomide given in combination with Fludarabine, Cyclophosphamide and at evaluating the (CR) rate of FC given in combination with the MTD of Lenalidomide (FCL).

GOELAMS LLC98 is a prospective randomized trial comparing in previously untreated B and C Binet stages B-CLL and on an intent to treat basis two strategies. Conventional chemotherapy consisted of six monthly courses of CHOP, followed by 6 CHOP courses every other 3 months in case of response. Experimental arm consisted of high dose therapy with autologous CD34+ purified progenitor cell support, used as consolidation of Complete Remission or Very Good Partial Response obtained after 3 monthly courses of CHOP, followed by 3 to 6 monthly-courses of fludarabine in case of insufficient response.
