Active clinical trials for "Lymphoma"

The purpose of this study is to compare the standard CHOP-R regimen of Cyclophosphamide, Doxorubicin, Vincristine, Prednisone, and Rituximab to CPOP-R (same regimen, but substituting Doxorubicin with Pixantrone). The objective is to show that CPOP-R is not inferior to CHOP-R.

Conventional therapy is effective for diffuse aggressive lymphomas and low grade lymphomas, but is limited by relapse occurs in 40 to 50% of subjects. This study assesses autologous stem cell transplant (ASCT) supplemented with high-dose therapy increases the event-free survival in diffuse aggressive lymphomas and low grade lymphomas, as an alternative to the limitations of conventional therapy. Preliminary studies with rituximab in low grade lymphomas indicate a response rate of about 50% with very little toxicity. Rituximab is hypothesized to be a candidate for post-transplant therapy because the majority of malignant lymphomas express the CD20 antigen; rituximab has impressive independent anti-tumor activity; and the antibody has little toxicity outside of the acute administration.

The purpose of this study is to evaluate the safety of an experimental drug called Elsamitrucin in people with non-Hodgkin's lymphoma and to see if it can shrink their tumors. Elsamitrucin has not been approved by the Food and Drug Administration (FDA). However, the FDA is permitting the use of this drug for this study.

This is an open label pilot study of 40 evaluable patients receiving vinorelbine-gemcitabine combination chemotherapy with filgrastim support in an outpatient setting. Participating patients at the time of registration will have measurable relapsed or primary refractory lymphoma.

Primary Objective: To determine the toxicity profile and maximum tolerated dose (MTD) of VELCADE when administered in combination with CHOP + Rituximab to patients with previously untreated diffuse large B cell or mantle cell non-Hodgkin's lymphoma (NHL) Secondary Objectives: To assess the response rate (overall and complete), event-free survival and overall survival with VELCADE and CHOP-R in patients with previously untreated diffuse large B cell or mantle cell lymphoma (phase II component) Treatment: Standard CHOP chemotherapy administered every 21 days (full dose) for six cycles Rituximab administered (375 mg/m2) day 1 of each cycle (with usual premedications) VELCADE is administered prior to rituximab and CHOP on day 1 of each cycle. The dose of VELCADE will be determined by the following dose escalation schedule: Level Dose/Schedule (-2) 0.7 mg/m2 on day 1 of each cycle (-1) 0.7 mg/m2 on days 1 and 8 (0) 0.7 mg/m2 on days 1 and 4 (+1) 1.0 mg/m2 on days 1 and 4 (+2) 1.3 mg/m2 on days 1 and 4

The purpose of this trial is to determine if combination therapy with rosiglitazone and bexarotene might have a synergistic effect in the treatment of patients with CTCL.

Blood and marrow stem cell transplant has improved the outcome for patients with high-risk hematologic malignancies. However, most patients do not have an appropriate HLA (immune type) matched sibling donor available and/or are unable to identify an acceptable unrelated HLA matched donor through the registries in a timely manner. Another option is haploidentical transplant using a partially matched family member donor. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including GVHD and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the body tissues of the patient (the host) are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for significant infection. For these reasons, a primary focus for researchers is to engineer the graft to provide a T cell dose that will reduce the risk for GVHD, yet provide a sufficient number of cells to facilitate immune reconstitution and graft integrity. Building on prior institutional trials, this study will provide patients with a haploidentical graft engineered to specific T cell target values using the CliniMACS system. A reduced intensity, preparative regimen will be used in an effort to reduce regimen-related toxicity and mortality. Two groups of patients were enrolled on this study. One group included those with high-risk hematologic malignancies and the second group included participants with refractory hematologic malignancies or undergoing a second transplant. The primary aim of the study was to estimate the relapse rate in the one group of research participants with refractory hematologic malignancies or those undergoing second allogeneic transplant. Both groups will be followed and analyzed separately in regards to the secondary objectives. This study was closed to accrual on April 2006 as it met the specific safety stopping rules regarding occurrence of severe graft vs. host disease. Although this study is no longer open to accrual, the treated participants continue to be followed as directed by the protocol.

This study is being conducted to determine the safety, side effects, and response to a combination of an established high-dose chemotherapy regimen, plus the addition of Rituximab (which is a form of immunotherapy).

The purpose of this study is to determine the efficacy and the safety profile and toxicity of a combination of Velcade™ (bortezomib) with a standard chemotherapy regimen (ACVBP [doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone]) in the treatment of previously untreated patients with peripheral T-cell lymphoma (PTCL).

The purpose of this study is to provide an opportunity for patients who exhibit progressive disease while receiving placebo on the companion 93-04-11 study to receive ONTAK. It is also designed to determine the effectiveness of ONTAK in Cutaneous T-cell Lymphoma (CTCL) patients whose tumors do not express CD25.
