Filter by:Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint swelling, pain, stiffness, damage, and ultimately loss of joint function. Scientists estimate that about 1.3 million people (0.6 percent) of the U.S. adult population have RA. Current therapies target the immune system early in the disease process before joint damage occurs, and include drugs such as methotrexate (MTX) and tumor necrosis factor (TNF)-blocking agents. Rituximab is a disease-modifying antirheumatic drug (DMARD) recently approved by the FDA for use in combination with MTX for treatment of moderately to severely active RA in patients who have had an inadequate response to TNF-blocking agents, in an effort to try to slow the course of the disease. This study will examine the effects of rituximab on the immune response and disease activity in participants with early RA who have not been treated with any disease-modifying agent. In addition, the safety and tolerability of rituximab in this population will be examined.
This Phase IIIb, randomized, multi-national, multi-center, blinded study of Infliximab (IFX) in subjects aged 18 and older with active RA is being conducted to assess whether increasing either the infusion dose or infusion frequency in patients presenting with a disease flare after an initial response to infliximab results in a significant improvement in disease activity. Subjects responding to an initial infliximab treatment regimen, who flare during continuation of treatment at 3 mg/kg administered every 8 weeks, will be randomly assigned to one of 3 different dosing regimens of infliximab and will be treated for 4 or 5 consecutive infusions for a total duration of 24 weeks. The infliximab control group and the infliximab increased dose group are evaluator and subject-blinded. The increased frequency group is not blinded. Clinical assessments of disease activity will be based the European League Against Rheumatism (EULAR) criteria for response. Safety parameters will be assessed at every infusion. A disease flare is defined by an increase in DAS28 with 0.6 or more at screening, when compared to the DAS28 score measured immediately prior to the last Remicade® infusion and depends upon the actual score as well. Since prior to enrollment, the subject received Remicade® as per routine clinical practice, the days on which infusions were administered and assessments are done during the induction period do not have to be exactly at Week 2, 6 and 14. - Drug: Infliximab Control (double-blinded) - Drug: Infliximab Increased Dose (double-blinded) - Drug: Infliximab Increased Frequency (open-label)
Rheumatoid arthritis (RA) is the most common inflammatory arthritis and a major health problem. The purpose of this study is to determine the safety and effectiveness of lovastatin for controlling inflammation in mildly active RA.
The primary objective of this study was to evaluate the tolerability and safety of rituximab in combination with methotrexate (MTX) and etanercept or adalimumab in participants with active rheumatoid arthritis (RA). The secondary objective was to explore the efficacy of rituximab in combination with MTX and etanercept or adalimumab in participants with active RA.
To compare the efficacy of SMP-114 (120 and 240 mg/d) versus placebo in terms of the percentage of patients meeting the American College of Rheumatology criteria for 20% improvement in RA (ACR20) at week 24. The study hypothesis would be to demonstrate that the use of methotrexate and SMP-114 is more efficacious than Methotrexate alone.
The purpose of the study is to evaluate the clinical performance of the cruciate ligament retaining or cruciate ligament substituting implants by obtaining a series of primary TKAs. Outcome scoring and radiographic assessment will be the methods used to evaluate performance.
Rheumatoid arthritis disease is believed to be due to immune cells, cells that normally protect the body and are now causing damage to the body. Risk of death is highest in people with twenty or more joints actively involved with disease, positive rheumatoid factor, an elevated sedimentation rate (laboratory measures of active inflammation), and patients with limitation of daily activities (trouble doing simple things like opening a carton of milk). In these high risk patients, life is significantly shortened. Death is usually from heart disease, kidney failure, neck dislocation, broken hip bones, or blood clots to the lung. In this study we use moderate dose chemotherapy (cyclophosphamide and fludarabine) and CAMPATH-1H (a protein that kills the immune cells that are thought to be causing the disease), followed by infusion of blood stem cells that have been collected from the patient's brother or sister (allogeneic stem cell transplant). The purpose of the moderate dose chemotherapy and CAMPATH-1H is to destroy the cells in the immune system and to allow the cells from the patient's brother or sister to grow. The purpose of the stem cell infusion is to restore blood cell production, which will be severely impaired by the moderate dose chemotherapy and CAMPATH-1H, and to produce a normal immune system that will no longer attack the body.
To evaluate the efficacy of fontolizumab in subjects with active rheumatoid arthritis as determined by a 50% improvement of an American College of Rheumatology criteria (ACR50) response at Week 14 (Stage A of study).
Rheumatoid arthritis (RA) is a chronic illness, immunologically mediated, probably induced by the exposure to an antigen or antigens, to which immunologic tolerance is lost. The disease has a variable course, from a mild, intermittently symptomatic illness requiring only symptomatic therapy to a fulminant illness requiring dangerous immunosuppressive therapy, surgery or both. The molecular defect causing RA has not been characterized, but may involve aberrant T cell, B cell, and macrophage function. Although RA often responds to immunosuppressive medication including corticosteroids, methotrexate, azathioprine and cyclophosphamide, or to non-steroidal anti-inflammatory drugs, no therapy has been curative. In patients with severe RA, who have been unresponsive to corticosteroids, and who have more than 20 active joints or vasculitis, we propose, as a phase I-II study, complete immune ablation and subsequent reconstitution with autologous in vitro T lymphocyte depleted PBSCs harvested from the patient prior to immune ablation. The combination of high dose cyclophosphamide and anti-thymocyte globulin conditioning will be followed by rescue with autologous lymphocyte depleted PBSCs. Subsequent disease activity will be followed by: (1) RA disease activity index, (2) type and amount of therapy for RA, and (3) flow cytometry of peripheral blood lymphocyte subsets, (4) joint count, (5) patients' assessment of pain, (6) arthritis impact measurement scales (AIMS) questionnaire, (7) acute phase reactants. This study will dose standard therapy, i.e. immune suppression, to the point of complete immune ablation and subsequent recapitulation of lymphocyte ontogeny by PBSC rescue. We anticipate that this study will also form the basis to clarify further the role of the immune system in RA.
This is a Phase 4 open label, non-interventional, multi-center study to evaluate the safety of Enbrel (etanercept) treatment in patients receiving etanercept 25mg sc twice weekly or 50mg of etanercept once weekly. The improvement of health-related quality of life will also be evaluated.
