Active clinical trials for "Arthritis"

This is a postmarketing study to assess the overall performance and survivorship of the SIGMA HP® PARTIAL KNEE SYSTEM.

The purpose of the study is to analyse the clinical and radiological results of a postero-stabilized TKA by using a mobile bearing versus fixed. Only patients with medial femorotibial arthritis will be included. The consequences on the patellofemoral joint will be thoroughly analysed on skyline view.

A study to compare rofecoxib versus naproxen in the treatment of Chinese patients with rheumatoid arthritis.

Self-management is critical for patients with chronic conditions such as rheumatoid arthritis. Such management requires that patients understand what to do to best manage their condition. This study will use a randomized controlled study design to evaluate the impact of a new educational intervention consisting of an educational digital video disc (DVD) and a self-management support session/teleconference with a multidisciplinary team of health care providers for patients (n=150) with active rheumatoid arthritis (RA) starting on or changing biologic agents. This study aims to test whether this intervention improves behavioural intentions, knowledge, and medication adherence three months post-intervention and whether acquired knowledge is retained six months after the intervention. This project will allow to quantify the impact of the educational intervention on patients' behavioural intentions in practical situations using an existing validated questionnaire called BioSecure. The impact of the educational intervention on disease-specific knowledge and on medication adherence will be evaluated using validated questionnaires.

An Agency for Healthcare Research and Quality executive summary indicated that better comparative effectiveness trial designs are needed to determine the relative merits of existing versus new and expensive biologic drug therapies for rheumatoid arthritis (RA). There are now 9 biologic therapies approved for treating RA. Four classes of biologics (TNF antagonists, B-cell inhibitors, T-cell co-stimulator blocker, and Interleukin-6 receptor blocker) are approved for use in RA patients with moderate or severe disease activity. Several critical questions have arisen, such as 1) what therapy should be prescribed after failure of methotrexate and/or other oral disease modifying antirheumatic drugs (DMARDs) to adequately control disease activity; 2) what is the level of efficacy of the various biologic therapies when compared in head-to-head trials; and 3) what are the mechanisms associated with failure of methotrexate and/or other oral DMARD therapy and responsiveness to biologic therapies. The MAZERATI study will provide the foundation for answering these questions and determining the mechanisms associated with these biologic therapies.

Study to assess the safety and tolerability of MEDI5117 in Rheumatoid Arthritis patients

Taking into account the recommendations of the Health Authority [1] and the application of patients' associations, we have structured a course of therapeutic education includes three stages for patients with rheumatoid arthritis and followed at Nantes University Hospital. Step 1: initial interview with a nurse patient education for diagnosis and education with the patient to choose three subjects from among 10 offered him problematic; Step 2: Orientation in an educational path that provides access to 6 months group workshops (3 maximum) and / or interviews tailored to the three selected topics; Step 3: final interview with a nurse said therapeutic education formative assessment to take stock. The main objective of our work is to ensure that the patient finds it easier solutions to the three problematic topics him after 6 months of education after six months without treatment.

This is an adaptive Positron Emission Tomography/ Computed Tomography (PET/CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) open-label study design for the investigation of inflammation in adult rheumatoid arthritis (RA) patients, not involving therapeutic intervention. Each study participant will undergo two half body PET/CT scans from the pelvis to the bottom of the feet (including hands and wrists) with an additional bed position centred on the shoulders. One scan will be conducted with 18F-FDG and the other with 18F-GE-180. The first PET/CT scan (PET1) will be performed 4 weeks (28 +/- 2 days) after the first screening visit, whereas the second PET/CT scan (PET2) will be carried out within 2 weeks (7 +/- 7 days) after PET1. The order of PET/CT scans for each subject will be based on a computer generated randomisation schedule after the screening visit. A sub-group of study participants will be invited to undergo an additional dynamic 18F-GE-180 PET scan of a selected joint (knee or wrist) prior to their 18F-GE-180 PET/CT half body scan. The primary objective of the study is to quantify inflammation in joints of RA patients by determining 18F-FDG and 18F-GE-180 uptake using PET, and DCE-MRI parameters.

In Ontario, rheumatology services are in short supply. Many people with inflammatory arthritis (IA) are traveling long distances for care and face geographical/ financial challenges in so doing. Travel burden may be decreased and satisfaction with care improved by integrating existing health care resources. A few rheumatologists in Ontario have adopted a video conferencing (VC) model for follow-up of stable IA patients using the Ontario Telemedicine Network (OTN) with Extended Role Practitioners (ERPs) doing on-site assessments. Anecdotal evidence suggests this model benefits both patient and rheumatologist. We will determine how people with stable well-controlled IA, living more than 100 km round-trip from the rheumatology clinic, perceive quality of life before, during and after VC with ERP follow-up visits compared to usual care. Disease activity, functional status, medication adherence, patient satisfaction, and barriers to care will also be measured.

This study will investigate whether inhibitors of the JAK / STAT signaling pathway can increase anti-inflammatory functions of B cells in patients with RA using in vitro and in vivo experiments.
