Active clinical trials for "Lymphoma, B-Cell"

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.

This randomized phase III trial studies rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell non-Hodgkin's lymphoma. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Drugs used in chemotherapy 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 rituximab together with combination chemotherapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective when given with rituximab in treating diffuse large B-cell non-Hodgkin's lymphoma. PURPOSE: This randomized phase III trial is studying rituximab when given together with two different combination chemotherapy regimens to compare how well they work in treating patients with diffuse large B-cell lymphoma.

This pilot phase II trial studies the side effects and how well giving gemcitabine hydrochloride, carboplatin, dexamethasone, and rituximab together works in treating patients with previously treated lymphoid malignancies. Drugs used in chemotherapy, such as gemcitabine hydrochloride, carboplatin, and dexamethasone, 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) and giving monoclonal antibody therapy with chemotherapy may kill more cancer cells

Phase II trial to study the effectiveness of combining bryostatin 1 with vincristine in treating patients who have progressive or relapsed non-Hodgkin's lymphoma after autologous bone marrow transplantation or autologous stem cell transplantation. Drugs used in chemotherapy such as vincristine use different ways to stop cancer cells from dividing so they stop growing or die. Bryostatin 1 may help vincristine kill more cancer cells by making the cells more sensitive to the drug

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 purpose of this study is to evaluate the safety and effectiveness of VELCADE when given in combination with rituximab in patients with Relapsed or Refractory Indolent B-Cell Lymphoma. This study will investigate if treatment with VELCADE and rituximab increases the time it takes your lymphoma to get worse.

This clinical trial studies fludarabine phosphate and total-body radiation followed by donor peripheral blood stem cell transplant and immunosuppression in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood 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. 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation together with fludarabine phosphate, cyclosporine, and mycophenolate mofetil before transplant may stop this from happening.

The goal of this clinical research study is to learn if the combination of oblimersen sodium and rituximab can help to shrink or slow the growth of the tumor in patients with B-cell non-Hodgkin's lymphoma who have not responded to earlier treatment. Oblimersen Sodium is an investigational drug. The safety of this combination treatment will also be studied

This phase II trial studies the side effects and the best dose of alemtuzumab when given together with fludarabine phosphate and low-dose total body irradiation (TBI) and how well it works before donor stem cell transplant in treating patients with hematological malignancies. Giving chemotherapy and low-dose TBI before a donor peripheral blood 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 alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal 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. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after transplant may stop this from happening.

The idiotype of the immunoglobulin on a given B cell malignancy (Id) can serve as a clonal marker, and a previous pilot study in lymphoma patients has demonstrated that autologous Id protein can be formulated into an immunogenic, tumor specific antigen by conjugation to a carrier protein (KLH) and administration with an emulsion-based adjuvant. The goals of vaccine development in the current study are to develop vaccines: 1) with improved potency and 2) which are more effective at inducing cell-mediated immune responses. The selection of GM-CSF as the immunological "adjuvant" is a direct extension of our laboratory studies in small animal models demonstrating that GM-CSF can enhance the potency of the prototype Id-KLH vaccine by augmenting almost exclusively the cellular arm of the immune response. The objectives of this study are: 1) to evaluate cellular and humoral immune responses against the unique idiotype of the patient's lymphoma and 2) to evaluate the ability of the Id vaccine to clear the bone marrow of malignant cells detectable by pathologic examination or molecular examination (polymerase chain reaction amplification of the rearranged bcl-2 oncogene). The goal of this study is to treat previously untreated patients with follicular lymphomas to complete remission or minimal residual disease with ProMACE chemotherapy. Three to six months after completion of chemotherapy, in an effort to reduce the relapse rate (by eradicating microscopic disease resistant to chemotherapy), patients will receive an autologous Id vaccine administered in combination with GM-CSF. Id-KLH (0.5 mg) is administered subcutaneously. GM-CSF is administered subcutaneously locally with the vaccine on the day of vaccination and for the three consecutive days following vaccination as close to the initial vaccination site as possible at one of two doses (patients are randomized to either a high or low dose, 500 or 100 micrograms/m2). We plan to accrue 42 patients. Twenty-nine patients have been enrolled. Sixteen patients have entered and/or completed the vaccination phase. Patients have demonstrated significant lymphoproliferative responses specific for autologous idiotype of a magnitude which is significantly greater than previously observed.
