Filter by:The purpose of this interventional study is to determine whether tetracyclines, statins, antiviral and Vitamin D3 in single subministration are effective in improvement of life and health condition in the treatment of rheumatoid arthritis due to autoimmune disease (RA) in all his forms, specially in patients intolerant to commonly used treatments.
The purpose of the study is to determine a) if the implementation of abatacept (Orencia®) patient alert card (PAC) resulted in effective understanding of key safety messages and b) if the degree of understanding of key safety messages is associated with improved clinical and safety outcomes.
The study is designed as a prospective, observational study to assess the effect of adalimumab on health-related quality of life (QoL) and work productivity in patients with rheumatoid arthritis (RA) in Korea.
This study will consist of two parts: Part A will evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of tirabrutinib in healthy participants. Part B will evaluate the safety, tolerability, and the effect of tirabrutinib on disease-specific clinical markers and outcomes in participants with rheumatoid arthritis (RA).
The purpose of the study is to obtain an overall picture of rituximab treatments and treatment responses in RA patients.
Preliminary data suggest that up-regulation of Interleukin -17 (IL-17) and the T-helper 17 (Th17) pathway occurs in rheumatoid arthritis (RA) patients on anti-Tumour Necrosis Factor (TNF) therapy who demonstrated an incomplete clinical response. A deeper understanding of this is required in order to determine whether IL-17 or the Th17 pathway is a valid target for intervention in this population to improve response outcome. The study objective is to observe biologic naïve RA subjects on anti-TNF therapies and take measurements of peripheral blood and synovial tissue to assess differences in the IL-17 and Th17 pathways between responders and non-responders. The aim of the study is to test if increased Th17 pathway activity is present in subjects who do not respond clinically to anti-TNF therapy. Clinical assessments, synovial bio-markers and ultrasound will be used as determinants of clinical response. The study may identify disease characteristics that determine which subjects may be more likely to respond to anti-TNF therapy, or those who may require either a different treatment option, or additional pathway inhibition in addition to TNF, in order to achieve clinical response.
The objective of this study is to determine the longitudinal relation between clinical remission and ultrasound (US) remission in Rheumatoid arthritis (RA). At a patient level, US-detected residual synovitis (evaluated both by US grey-scale signals and power Doppler signals) is frequent in patients with RA in clinical remission. Several longitudinal studies reveal an association of US-detected residual synovitis and risk of relapse and radiographic progression, in individual patients and joints, over 1-2 years. However, the longitudinal relation between clinical remission and US remission is not so well-known and it is possible that clinical remission arrive before ultrasound remission. Thus arise the question as to whether the presence of US-detected residual synovitis require to adapt the treatment to ultrasound findings or to simply increase the patient care. The investigator propose to conduct a prospective, bi-center, non randomized study.
The study is designed as a prospective, observational study to assess the effect of adalimumab on health-related quality of life (QoL) and work productivity in patients with rheumatoid arthritis (RA) in Taiwan.
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.
This multicenter, prospective, non-interventional study is designed to obtain an accurate estimation of the drug retention rate of Tocilizumab (TCZ) Subcutaneously (SC) under real-world conditions in participants with moderate to severe rheumatoid arthritis (RA).
