Active clinical trials for "Arthritis, Rheumatoid"

Rheumatoid Arthritis (RA) is an autoimmune disease that results in a chronic inflammatory disorder that may affect many synovial joints, and may cause serious disability. It has been confirmed that Tripterygium Wilfordii has effects of anti-inflammatory, immunosuppressive and cartilage protection. This is a multicenter ,double Blind, randomized study to evaluated the efficacy and safety of Tripterygium Wilfordii in treating of patients with rheumatoid arthritis (RA) and establish a prediction model for Tripterygium Wilfordii response of rheumatoid arthritis (RA).

Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects the joints, causing pain, edema, physical disability and poor quality of life. In addition, RA patients are at increased risk of developing cardiovascular disease (CVD) and premature death. The most effective pharmacological treatment is the use of biological agents that inhibit the action of specific substances, such as interleukin 6 (IL-6) and tumor necrosis factors (TNF). Physical exercise is considered a first-line non-pharmacological treatment in RA, improving inflammatory and metabolic profile, functional capacity, fatigue and preventing the onset of CVD. There is evidence that IL-6, when secreted as a result of exercise, brings several benefits. However, there is no study investigating the interaction between biological IL-6 blocking agents and exercise on metabolic responses, such as insulin sensitivity and glucose uptake, in patients with RA. To answer this question, adult women diagnosed with RA and healthy controls will be recruited for an acute session of exercise. RA patients will be divided into 2 groups, according to the pharmacological treatment (tocilizumab or anti-TNF). The acute responses of insulin sensitivity after an acute session of exercise will be assessed by the hyperinsulinemic euglycemic clamp, and the molecular pathways will be assessed by muscle biopsy and gene and protein expression analysis. Positron emission tomography-magnetic resonance imaging (PET/MRI) will be performed to quantify skeletal muscle glucose uptake.

To evaluate the therapeutic effect of 3 local doses of PRP intra-articular injection in patients with RA regarding the improvement of disease activity and quality of life versus placebo.

This study will examine the clinical response, cytokine expression and joint imaging after addition of Acthar Gel. The hypothesis is that H.P. Acthar Gel is both safe and effective for treatment of patients with refractory rheumatoid arthritis (RA) and has different mechanism of action than steroids and other DMARDs.

Early initiation of treatment for Rheumatoid arthritis (RA) can prevent several of the long term problems associated with the condition. However, many RA patients develop lung inflammation and scarring, called 'interstitial lung disease' (RA-ILD), contributing to early death in 1 in 5 people. There is no proven treatment for these patients and some medications for RA can in fact worsen their lung disease. There is a need therefore to find safe medications that can not only control RA joint disease, but also prevent progression of RA-ILD. Abatacept is an approved drug for treating RA and is used widely. It is a newer RA medication, with a unique mechanism of action, and it has been shown to prevent progression of joint damage and improve physical function. The investigators aim to assess the safety of this medication in patients with RA-ILD and improve our understanding of the mechanism of lung damage in rheumatoid disease. The investigators will perform a small clinical trial to assess the feasibility of performing a larger randomized controlled trial. A total of 30 patients with RA-ILD will be treated with abatacept infusions fortnightly for the first month, then every 4 weeks for a total of 20 weeks. In order to be eligible for the study, a patient must be able to provide written informed consent, be aged ≥18 years, and have interstitial lung disease that has not responded to or progressed over 6 months despite conventional immunosuppression. Change in lung function (forced vital capacity) at 24 weeks will be evaluated. To assess the mechanisms that may be involved with the development of ILD, the investigators will assess the effects of abatacept on biomarkers obtained from the blood and the lung (bronchoalveolar lavage), including markers of infection (the lung microbiome).

The purpose of this open-label, randomized, two-period, two-treatment (single doses of 10 mg SHR0302 fasted or fed), crossover study was to evaluate the effect of a high-fat meal on the pharmacokinetics of SHR0302 and mass balance study in 14 healthy subjects.

The purpose of this study is to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cell(hUC-MSC) for Rheumatoid Arthritis.

The purpose of the study is to evaluate the safety and tolerability of single ascending (SAD) oral doses of SHR0302 compared to placebo. Also, pharmacokinetics (PK) and pharmacodynamics (PD) of SHR0302 after single oral administration will be evaluated, and, if applicable, the maximum tolerated dose determined.
