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

This randomized, parallel-group, multi-center study will compare the pharmacokinetics and safety of subcutaneous administration of MabThera (rituximab) versus intravenous MabThera in combination with chemotherapy in previously untreated patients with chronic lymphocytic leukemia (CLL). The study consists of 2 parts. In part 1, patients who have previously received 4 cycles of intravenous MabThera will receive in Cycle 5 intravenous MabThera and in Cycle 6 subcutaneous MabThera. In part 2, patients will be randomized to receive either 6 cycles of intravenous MabThera, or 1 cycle of intravenous MabThera and 5 cycles of subcutaneous MabThera. Additionally, all patients will receive chemotherapy (fludarabine and cyclophosphamide) on Days 1-3 or Days 1-5 of every cycle. The anticipated time on study drug is 24 weeks.

Phase II, multicenter, randomized trial, exploring intensified Rituximab prephase monotherapy before standard Fludarabine-Cyclophosphamide-Rituximab FC-R regimen in previously untreated symptomatic B-cell chronic lymphocytic leukemia CLL. A Study from the Goelams GCFLLCMW intergroup

This is a multi-center, phase 1, open-label first-in-human study of AMG 319 in subjects with relapsed or refractory lymphoid malignancies. This study consists of two parts. The dose exploration in part 1, studies cohorts of 3 subjects with relapsed or refractory lymphoid malignancies and uses a practical continuous reassessment model [CRM] to guide dose escalation and to define the MTD. The dose expansion in part 2 will enroll 20 subjects with CLL at a dose no higher than the MTD and further explore the safety, PK, and clinical activity of AMG 319 in this patient population.

The goal of this clinical research study is to learn if eltrombopag can help to increase the number of platelets in patients with CLL. The safety of this drug will also be studied.

The rationale for combining lenalidomide with rituximab derives from preclinical observations suggesting that lenalidomide may enhance the ADCC (antigen-dependent cellular cytotoxicity) triggered by monoclonal antibodies such as rituximab. Lenalidomide augments NK cytotoxicity by increasing CD56dimCD3 subset, in addition to inducing IL-2 in T cells. These results provide the cellular and molecular basis for the use of lenalidomide as an adjuvant in immunotherapeutic strategies of monoclonal antibodies (mAb)-based therapies. The combination lenalidomide-rituximab was tested in lymphoma cell lines but not specifically on CLL cell lines. However the observed synergism was attributed to NK cells expansion, thus lending support to the notion that this synergism may operate in other B-cell lymphoproliferative malignancies. The objective was to develop a non-cytotoxic and effective treatment for CLL that would fulfill an unmet medical need, as a significant proportion of CLL patients are elderly and frail. These patients experience an excess in chemotherapy induced toxicity, often preventing the completion of the planned treatment.

This phase II trial is studying how well AZD2171 works in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia. AZD2171 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer cells

This randomized phase III trial is studying fludarabine, cyclophosphamide, and rituximab to see how well they work compared to fludarabine and cyclophosphamide in treating patients with B-cell chronic lymphocytic leukemia.

RATIONALE: Giving combination chemotherapy before a peripheral blood stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. A monoclonal antibody, such as alemtuzumab, is given to kill any remaining cancer cells. Chemotherapy and radiation therapy (total-body irradiation) are given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. Giving combination chemotherapy, total-body irradiation, and alemtuzumab together with autologous peripheral stem cell transplant may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with total-body irradiation and alemtuzumab works in treating patients undergoing an autologous stem cell transplant for stage I, stage II, stage III, or stage IV chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy, such as fludarabine, cyclophosphamide, and mitoxantrone, 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. Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others can find cancer cells and help kill them or carry cancer-killing substances to them. Combination chemotherapy followed by alemtuzumab may be effective in treating chronic lymphocytic leukemia and prolymphocytic leukemia. PURPOSE: This phase II trial is studying how well giving combination chemotherapy followed by alemtuzumab works in treating patients with T-cell chronic lymphocytic leukemia or prolymphocytic leukemia.

This phase I trial is studying the side effects and best dose of PXD101 and bortezomib in treating patients with advanced solid tumors or lymphomas. PXD101 and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PXD101 may also cause cancer cells to look more like normal cells, and to grow and spread more slowly. Giving PXD101 together with bortezomib may kill more cancer cells.
