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

This study aims to assess the short term efficacy of a combination immunochemotherapy in patients with relapsed B-cell chronic lymphatic leukemia.

RATIONALE: BL22 immunotoxin can find tumor cells and kill them without harming normal cells. PURPOSE: This phase I trial is studying the side effects and best dose of BL22 immunotoxin in treating patients with refractory B-cell chronic lymphocytic leukemia, prolymphocytic leukemia, or non-Hodgkin's lymphoma.

This is a Phase II trial to study the safety and tolerability of subcutaneous alemtuzumab administered without dose escalation to patients with advanced B-cell chronic lymphocytic leukemia (B-CLL).

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combining UCN-01 with fludarabine in treating patients who have relapsed or refractory chronic lymphocytic leukemia or lymphocytic lymphoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of dolastatin 10 in treating patients with indolent lymphoma, Waldenstrom's macroglobulinemia, or chronic lymphocytic leukemia.

This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.

The purpose of this study is to determine the side effects and antitumor response of patients with lymphoid malignancies to Deoxycoformycin (DCF)/Pentostatin.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of cladribine when given with bryostatin 1 in treating patients with relapsed chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells. PURPOSE: Randomized phase II trial to compare the effectiveness of fludarabine given with or without monoclonal antibody therapy followed by monoclonal antibody therapy alone in treating patients who have untreated B-cell chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known whether combining cyclophosphamide with fludarabine is more effective than fludarabine alone in treating chronic lymphocytic leukemia. PURPOSE: Randomized phase III trial to study the effectiveness of fludarabine with or without cyclophosphamide in treating patients who have chronic lymphocytic leukemia that has not been treated previously.
