Active clinical trials for "Arthritis, Rheumatoid"

Rheumatoid Arthritis (RA) is a chronic, autoimmune inflammatory disease that leads to significant pain, joint destruction and functional decline, and has a substantial economic impact both for sufferers and society. Although the etiology of RA is unknown, it is generally accepted that it arises from an interplay of genetic predisposition (in particular, HLA-DR allele subtypes and specific gene polymorphisms), immunological deregulation (e. g. autoantibody production), and environmental factors. The prevalence and incidence of RA in Norway is estimated to 0,4-0,5 % and 0,020-0,025 %, respectively, and incidence rates are 2-4-fold higher in women. Synovitis and bone resorption are key pathogenetic factors in RA and these patients have elevated cytokine levels in joints and blood (i.e. TNF, IL-1, IL-6). RA is also associated with significant comorbidity; the most important is premature cardiovascular disease that significantly contributes to increased mortality. Compared with the general population, mortality in RA is from 1,57-2,0-fold higher in Norway and Sweden, and their mean life expectancy is reduced by an average of 5-10 years. Medical treatment of RA consists of nonsteroidal anti-inflammatory drugs, systemic glucocorticosteroids, traditional disease modifying antirheumatic drugs (including methotrexate) and biologic therapies (including anti-tumor necrosis factor (TNF) α, anti-IL 6 and anti-CD20 therapy). Also, a considerable portion of the patients are in need of joint replacement surgery and in need of rehabilitation. However, the treatment opportunities are still not optimal. In a large proportion of the patients, full control of the disease is not possible due to limited effect of available therapies and/or intolerance to these therapies. Therefore, there is a huge need to find new therapeutic alternatives to treat RA. Since studies on healthy volunteers and IBD-patients support that the mushroom extract AndoSanTM exert an anti-inflammatory effect in vivo, the investigators wanted to examine in a pilot study whether this effect also was evident in patients with RA. A potential anti-inflammatory effect could prove beneficial in these seriously ill patients, who accordingly could experience less side effects (edema, granulocytopenia, diminished tissue repair) due to potential reduction number and dose of disease modifying drugs.

The main purpose of this study is to evaluate the safety of the study drug known as LY3090106 in healthy participants and in participants with RA who are having an inadequate response to methotrexate (MTX). The study will investigate how the body processes the study drug and how the study drug affects the body. The study will last about 3 months for each participant.

A study to Assess the Pharmacokinetics of Rosuvastatin and Simvastatin when administered alone or in combination with Fostamatinib.

This study is a randomized controlled trial designed to examine the efficacy of an educational decision support tool for patients with rheumatoid arthritis who continue to have active disease despite use of traditional disease modifying drugs. The study will take place at Geisinger Medical Center in Danville, PA. Eligible subjects will be identified by the treating physician and those providing consent will be randomized to usual care versus use of the decision support tool.

A Randomized, Double-blind, Multicenter, Phase 3 Study of Pelubiprofen Tab. & Celebrex Cap. for Comparative Evaluation of Safety & Efficacy in Rheumatoid Arthritis Patients

The purpose of this study is to access the effect (week 12/week 24) of puerarin injection on carotid intima-media thickness (CIMT) in rheumatoid arthritis (RA) patients despite routine anti-rheumatic treatment.

Recently, it has been shown that B cells could also have regulatory functions through the secretion of interleukin 10 (IL-10). They are called the B regulatory cells (Breg). In the mouse model the most commonly used of rheumatoid arthritis, collagen-induced arthritis (CIA), the transfer Breg helps prevent the development of CIA and cure established arthritis. The investigators have recently shown that Breg were decreased in patients with RA compared to controls and that the rate of Breg was inversely correlated with disease activity and autoantibody. These results thus suggest that the lack of IL-10 secretion by B cells plays an important role in the pathophysiology of RA. Nevertheless, in humans, the Breg remain poorly understood. The main objective of this project is to better characterize the B capable of producing IL-10 both in subjects with RA and controls. Understanding which induces the secretion of IL-10 by B could allow to consider new therapeutic approaches in autoimmune diseases, including in RA. The investigators therefore aim to identify nutrient transporters, chemokine receptors, genes and surface proteins differentially expressed between Breg and other B cells in patients with RA and in controls.

The purpose of the study is to assess whether, in individuals with rheumatoid arthritis, a low-fat, vegan diet improves pain and other subjective symptoms more effectively than a control supplement or a placebo. The principal measure is pain as measured by Visual Analog Scale (VAS) and disease activity as measured by number of painful swollen and tender joints, respectively. The study duration is 36 weeks.

To assess the effects of a 16-week individualized, intensive strength training program in patients with rheumatoid arthritis. Primary and secondary outcomes include: strength and body composition, function, disease activity, pain, quality of life. We hypothesized that improvements would be seen in all of the above outcomes.

The purpose of this study is to use abatacept as a clinical molecular probe to evaluate the effects of inhibiting costimulation on immune responses in patients with rheumatoid arthritis (RA).
