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

This phase I/II trial studies the side effects and best dose of donor natural killer (NK) cell therapy and to see how well it works when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, donor bone marrow transplant, mycophenolate mofetil, and tacrolimus in treating patients with hematologic cancer. Giving chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving an infusion of the donor's T cells (donor lymphocyte infusion) may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving mycophenolate mofetil and tacrolimus after the transplant may stop this from happening.

This study will evaluate the safety and effectiveness of a new drug called lenalidomide (Revlimid) for treating patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) who relapsed after their initial treatment. Patients 21 years of age and older with CLL or SLL who have previously received standard treatment may be eligible for this study. Participants take lenalidomide capsules once a day for 21 days, followed by 21 days off the drug. This constitutes one treatment cycle. Treatment continues for four cycles as long as the medicine is tolerated. After four cycles, patients who respond completely continue treatment for another two cycles; patients who respond partially continue treatment for another four cycles; and patients who do not respond stop treatment but continue to be followed for safety. ...

The goal of this clinical research study is to find the highest tolerable dose of fludarabine and cytarabine that can be given in combination with oxaliplatin and rituximab in the treatment of chronic lymphocytic leukemia (CLL), prolymphocytic leukemia, or Richter's transformation. Once the highest tolerable dose for this drug combination is found, the next goal of the study will be to find out if this combination therapy is effective in shrinking or slowing the growth of these diseases.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving more than one drug (combination chemotherapy) together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with rituximab works in treating patients with chronic lymphocytic leukemia (CLL) that has not responded to fludarabine (closed to entry as of 10/2006), CLL with autoimmune hemolytic anemia, or Richter transformation.

Drugs used in chemotherapy, such as CCI-779, work in different ways to stop cancer cells from dividing so they stop growing or die. This phase II trial is studying how well CCI-779 works in treating patients with recurrent or refractory B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia.

The purpose of this study is to determine whether the combination of alemtuzumab and rituximab is safe and effective in treating patients with relapsed Chronic Lymphocytic Leukemia (CLL) and to determine whether alemtuzumab can be given as a single weekly subcutaneous dose, together with rituximab.

This phase II trial is studying how well sunitinib works in treating patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. Sunitinib 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.

This phase I trial is studying the side effects and best dose of EMD 121974 in treating patients with solid tumors or lymphoma. Cilengitide (EMD 121974) may stop the growth of cancer cells by stopping blood flow to the cancer

The objectives of this study are to evaluate the safety and efficacy of OSI-461 in CLL patients.

Chemotherapy can often cause anemia in patients with cancer. Anemia is a low number of red blood cells. The symptoms of anemia may include fatigue, dizziness, headache, chest pain, and shortness of breath. Erythropoietin is a hormone made by the kidneys that signals the bone marrow to produce more red blood cells. Recombinant human erythropoietin has been produced in the laboratory and has the same effect as the hormone produced by the body. Use of recombinant human erythropoietin allows the body to produce more red blood cells, possibly eliminating or decreasing your symptoms and the need for a red blood cell transfusion. Recombinant human erythropoietin is FDA approved to treat anemia in cancer patients receiving chemotherapy. This clinical study is investigating the effectiveness of darbepoetin alfa for the treatment of anemia in patients with non-myeloid malignancies who are receiving chemotherapy every three weeks. Darbepoetin alfa is a recombinant erythropoietic protein that stimulates the production of red blood cells. This medication has not been approved to treat cancer patients with anemia, however it has been approved by the FDA to treat chronic renal failure patients with anemia.
