PURPOSE The CD20 antigen is expressed on more than 90% of B-cell lymphomas. It is appealing for targeted therapy, because it does not shed or modulate. A chimeric monoclonal antibody more effectively mediates host effector functions and is itself less immunogenic than are murine antibodies. PATIENTS AND METHODS This was a multiinstitutional trial of the(More)
PURPOSE Radioimmunotherapy combines biologic and radiolytic mechanisms to target and destroy tumor cells, thus offering a needed therapeutic alternative for refractory non-Hodgkin's lymphoma (NHL) patients. This phase III randomized study compares the novel radioimmunotherapy yttrium-90 ((90)Y) ibritumomab tiuxetan with a control immunotherapy, rituximab,(More)
PURPOSE Rituximab is commonly used as a single agent or in combination therapy for non-Hodgkin's lymphoma (NHL). Ibritumomab tiuxetan radioimmunotherapy targets the same antigen as rituximab and has demonstrated efficacy in rituximab-naïve NHL. This study evaluated ibritumomab tiuxetan in the treatment of rituximab-refractory follicular NHL. PATIENTS AND(More)
The complexity of the events of embryo implantation and placentation is exemplified by the number and range of cytokines with demonstrated roles in these processes. Disturbance of the normal expression or action of these cytokines results in complete or partial failure of implantation and abnormal placental formation in mice or humans. Of known importance(More)
Menstruation and endometrial regeneration occur during every normal reproductive cycle in women and some Old World primates. Many of the cellular and molecular events of menstruation have been identified by correlative or in vitro studies, but the lack of a convenient model for menstruation in a laboratory animal has restricted functional studies. In this(More)
IDEC-C2B8 is a chimeric monoclonal antibody (MoAb) directed against the B-cell-specific antigen CD20 expressed on non-Hodgkin's lymphomas (NHL). The MoAb mediates complement and antibody-dependent cell-mediated cytotoxicity and has direct antiproliferative effects against malignant B-cell lines in vitro. Phase I trials of single doses up to 500 mg/m2 and 4(More)
PURPOSE This phase II trial investigated the safety and efficacy of re-treatment with rituximab, a chimeric anti-CD20 monoclonal antibody, in patients with low-grade or follicular non-Hodgkin's lymphoma who relapsed after a response to rituximab therapy. PATIENTS AND METHODS Fifty-eight patients were enrolled onto this study, and two were re-treated(More)
BACKGROUND Monoclonal antibodies are being utilized for treatment of patients with low-grade non-Hodgkin's lymphoma as well as other cancers. Results from phase I and II clinical studies has shown that the chimeric monoclonal antibody Rituximab has minimal toxicity and significant therapeutic activity in low grade non-Hodgkin's lymphoma. PATIENTS AND(More)
BACKGROUND Rituximab is a chimeric monoclonal antibody directed against the B-cell CD20 antigen which has been utilized for therapy of B-cell non-Hodgkin's lymphoma (NHL). A previous clinical trial demonstrated that treatment with four weekly doses of 375 mg/m2 of Rituximab in patients with relapsed or refractory low-grade or follicular B-cell non-Hodgkin's(More)
PURPOSE Radioimmunotherapy (RIT) with yttrium-90 ((90)Y)-labeled anti-CD20 antibody ((90)Y ibritumomab tiuxetan; Zevalin, IDEC Pharmaceuticals Corporation, San Diego, CA) has a high rate of tumor response in patients with relapsed or refractory, low-grade, follicular, or transformed B-cell non-Hodgkin's lymphoma (NHL). This study presents the safety data(More)
