Active clinical trials for "Arthritis, Rheumatoid"

The purpose of this study is to find patterns in the use of non-biological DMARDs as the initial treatment of RA and how adverse events (AEs), intolerance or lack of efficacy may impact therapeutic decisions in real life in the Spanish Andalusian region.

The purpose of this study is to estimate the retention rate of Abatacept SC over 24 months in routine clinical practice, in rheumatoid arthritis patients, in each country involved in the study. The purpose of the UK substudy is to explore whether integrating self-assessment into routine care could maintain tight control (of inflammation/disease activity) and at potentially lower cost resulting in improved health outcomes and cost-effectiveness.

The purpose of this study is to examine the relationship between anti-drug antibodies, serum drug concentrations, and clinical response for rheumatoid arthritis patients being treated with etanercept, adalimumab or infliximab.

The purpose of this study is to assess Abatacept Intravenous (IV) effectiveness in patients with inadequate response to one or more conventional Disease Modifying Against Rheumatism (DMARDs) including Methotrexate in France, through the estimation of Abatacept retention rate over 2 years and reasons of discontinuation

Rheumatoid arthritis (RA) is a systemic disease, which mainly targets joints and results in osteoarticular destruction and serious disability. When clinical symptoms (painful and swollen joints) occur, the innate and adaptive immune responses against self antigens have already been largely amplified. This might explain that even when RA patients are treated very early and aggressively, a remission of the disease can only be obtained in approximately half of them. This proportion of remission under treatment can only be achieved using treat to target strategies involving biologics, such as anti-TNF. Unfortunately, less than 20% of patients remain in remission after treatment discontinuation. Thus, despite the availability of 5 different types of biologics, there are still therapeutic unmet needs. However, a spontaneous, drug-free decrease of disease activity can be observed in a physiological condition, pregnancy. Although most of treatments of RA have to be discontinued during pregnancy, a marked improvement, and sometimes remission, can be observed during pregnancy, with frequent post-partum flares. The situation is the opposite with an increased risk of flares in systemic lupus erythematosus (SLE), a rare systemic autoimmune disease which generally progresses in flares-up and can affect nearly any organ (the skin, joints, kidneys, the brain, the heart, …). The course of the disease remains unpredictable for a given patient, and very few biomarkers are available to help clinicians to identify patients a risk of flares. Thus, safe therapeutic options remain limited, especially in patients with serious complications. A specific concern in SLE is the fact that the disease usually starts in women entering their sexual and reproductive life. Even with a stable condition (i.e : lupus without recent flares and no impaired renal or cardiac function) as it is medically recommended before getting pregnant, up to 40% of SLE patients flare up during pregnancy. We hypothesize disease-specific and pregnancy-induced epigenetic changes, especially those regarding the pattern and levels of microRNAs, could explain the clinical improvement and the risk of flares in RA and SLE, respectively. A better understanding of the underlying mechanisms could help to identify new biomarkers, notably those predicting flares in SLE, and therapeutic targets, by trying to mimicking or amplifying micro-RNA changes observed in RA and targeting them in SLE.

This study aims to provide preliminary evidence of the validity of a sensor-based assessment of rheumatoid arthritis (RA) symptoms, and to collect structured qualitative feedback from RA Enbrel patients regarding the potential of a future biosensor/PRO mHealth application. The investigators' overarching hypothesis is that if patients have better and more timely information about whether Enbrel is working, then they will become more empowered and engaged in their treatment, more curious about how it may - or may not - be working, and potentially more compliant with therapy. However, this hypothesis remains largely untested.

The aim of this non-interventional, prospective, observational study is to assess the effectiveness and tolerability of RoActemra (tocilizumab) used as a first-line biologic treatment in participants with moderate to severe active RA who are inadequate responders to disease-modifying antirheumatic drugs (DMARDs), or participants who are intolerant to DMARDs, in a routine clinical practice setting in Poland. The length of the entire study will be 24 months.

ARATA is a prospective, non-interventional, multicenter, observational study in Germany to evaluate the long-term effectiveness and tolerability of subcutaneously administered tocilizumab in participants with rheumatoid arthritis in daily clinical practice. Participants will be followed over an observation period of up to 2 years after the initial injection.

The aim of this non-interventional study in Hungarian participants is to gather real life data about the efficacy and safety of tocilizumab SC monotherapy in RA, to assess data about pattern of usage of tocilizumab monotherapy in RA disease management.

This prospective, multi-center, observational study will assess the efficacy and safety of treatment in patients who are treated with a TNF Inhibitor or RoActemra/Actemra (tocilizumab) as the first biologic therapy. Data will be collected for 52 weeks.
