Active clinical trials for "Lymphoma, Large B-Cell, Diffuse"

This is a randomized, open-label, active-control, parallel-group, multicenter, multinational Phase 2 Study of the efficacy and safety of VELCADE, Rituximab, Cyclophosphamide, Doxorubicin, and Prednisone (VR-CAP) or Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (R-CHOP) in Patients With Newly Diagnosed Non-Germinal Center B-Cell (non-GCB) Subtype of Diffuse Large B-Cell Lymphoma (DLBCL)

The purpose of this study is to evaluate the safety and efficacy of Zevalin® in a Reduced Intensity Conditioning regimen followed by allogenic stem cell support in patients with aggressive lymphomas who are responsive to a salvage chemotherapy regimen.

RATIONALE: Studying PET scans given to patients with cancer who are undergoing treatment may help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is studying PET scans in patients with diffuse large B-cell lymphoma who are receiving rituximab together with cyclophosphamide, doxorubicin, vincristine, and prednisone.

This pilot trial studies different high-dose chemotherapy regimens with or without total-body irradiation (TBI) to compare how well they work when given before autologous stem cell transplant (ASCT) in treating patients with hematologic cancer or solid tumors. Giving high-dose chemotherapy with or without TBI before ASCT stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood or bone marrow and stored. More chemotherapy may be given to prepare 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.

The purpose of this study is to evaluate: whether an imaging test called a PET (Positron emission tomography) scan performed after two cycles of standard chemotherapy is able to identify patients who have a high cure rate after completing standard chemotherapy alone; and whether high dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT) when used in combination with an antibody called Rituximab results in high cure rates for those patients predicted to do poorly with standard chemotherapy by the PET scan.

A bone marrow transplant, which is a type of stem cell transplant, is a treatment option for people with leukemia or lymphoma. Recently, stem cell transplants using umbilical cord blood have become a treatment option for people with these types of cancers. This study will evaluate the effectiveness of a stem cell transplant using umbilical cord blood, along with lower doses of chemotherapy, to treat people with leukemia or lymphoma.

A phase II trial to evaluate the efficacy and safety of combination bendamustine and rituximab in patients with relapsed or refractory diffuse large B-cell lymphoma. It is hypothesized that the BR combination will produce at least a 70% overall response rate.

The primary objective of the protocol is to estimate the complete response rate of three courses of the association of rituximab, navelbine, ifosfamide, mitoxantrone, and prednisone in relapsed aggressive non hodgkin's B-cell lymphoma

Background: The National Cancer Institute (NCI) Surgery Branch has developed an experimental therapy for treating patients with B cell lymphomas or leukemias that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with a type of virus (retrovirus) to attack only the tumor cells, and then giving the cells back to the patient. This type of therapy is called gene transfer. In this protocol, we are modifying the patient s white blood cells with a retrovirus that has the gene for anti-cluster of differentiation 19 (CD19) incorporated in the retrovirus. Objective: The purpose of this study is to determine a safe number of these cells to infuse and to see if these particular tumor-fighting cells (anti-CD19 cells) cause tumors to shrink. Eligibility: - Adults age 18-70 with B cell lymphomas or leukemias expressing the CD19 molecule. Design: Work up stage: Patients will be seen as an outpatient at the National Institutes of Health (NIH) clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed Leukapheresis: If the patients meet all of the requirements for the study they will undergo leukapheresis to obtain white blood cells to make the anti-CD19 cells. Leukapheresis is a common procedure, which removes only the white blood cells from the patient. Treatment: Once their cells have grown, the patients will be admitted to the hospital for the conditioning chemotherapy and the anti-CD19 cells. They will stay in the hospital for about 4 weeks for the treatment. Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits will take up to 2 days.

The purpose of this study is to determine the recommended dose of CMC544 administered in combination with rituximab (R-CMC544), and in alternance with rituximab, gemcitabine and oxaliplatin (R-GEMOX) in the first phase of the study. After that, efficacy and safety of this combination will be evaluated preliminarily in patients with DLBCL in relapse or refractory, who are no candidates for autologous transplant.
