Filter by:This open-label randomized 2arm study will investigate the pharmacokinetics, pharmacodynamics, efficacy and safety of subcutaneously administered tocilizumab in patients with rheumatoid arthritis who have shown an inadequate response to methotrexate. Patients will be randomized to receive tocilizumab 162 mg sc either weekly or every other week, in combination with methotrexate, for 12 weeks. Assessments will be made at regular intervals during treatment and on the 3 weeks of follow-up.Target sample size is < 50 individuals.
The purpose of this study is to determine how well Rituximab works in early stages of disease and the effects it has on an inflamed joint and blood cells. This will allow the investigators to get a better understanding of how this treatment affects the inflamed joints of rheumatoid arthritis (RA) patients.
This study will test if CP-690,550 is safe and effective in rheumatoid arthritis patients taking methotrexate who have an inadequate response to tumor necrosis factor inhibitor treatment.
The purpose of this study is to demonstrate the relative bioavailability of Naproxen delayed-release tablets (375 mg).
The purpose of this study is to evaluate the safety and efficacy of ATN-103 when administered to subjects with active rheumatoid arthritis compared with placebo. All subjects must be on a stable dose and route of methotrexate.
This single arm study will assess the effect of tocilizumab + DMARDs (Disease Modifying Anti-Rheumatic Drugs)on improvement of anemia and fatigue in patients with moderate to severe active rheumatoid arthritis. Eligible patients who have had an inadequate response to DMARDs will receive tocilizumab 8mg/kg iv every 4 weeks in combination with standard DMARDs, for 6 months. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
Study in participants with RA who have an inadequate response to methotrexate.
More than half of rheumatoid arthritis (RA) patients complain of sleep disturbance and this cardinal complaint is associated with fatigue, pain, and depressed mood in patient with chronic inflammatory disorder. Despite the frequency of this complaint, there is limited efforts to evaluate sleep or the abnormal increases in the expression of pro-inflammatory cytokines play a key role in the progression of RA, we hypothesize that the cytokine network is one physiological system that is associated with sleep disturbances in RA patients. Pro-inflammatory cytokines signal the central nervous system and are associated with increased symptoms of pain, fatigue, and depressed mood in rheumatic patients. The specific aims of the study are to examine the contribution of cytokines on sleep by administering a TNF antagonist vs. placebo to probe the action of pro-inflammatory cytokines on sleep in RA Patients. Examination of sleep and its consequences for pro-inflammatory cytokine activity within the framework of an observational and experimental research design will have implications for understanding the psycho-biological mechanisms that link sleep and the clinical manifestations of RA. Results from this study will guide the developments of interventions that target disordered sleep with potential effects on disability in RA.
To demonstrate the relative bioavailability, parallel study Of Leflunomide 20 mg tablets under fasting conditions.
Polymorphisms occur in several genes encoding key enzymes in the folate pathway may affect drug metabolism in patients with rheumatoid arthritis. Whether these genetic variations contribute to differential responses to antifolate drug in patients with rheumatoid arthritis (RA) remains to be investigated in the Taiwanese population. Objective. The goal of the present study is to investigate the interactions between genetic variations in folate genes and the efficacy/side effects of anti-folate disease-modifying antirheumatic drug in Taiwan. DESIGN. A cross-sectional study involving 100 patients with RA were enrolled from TCVGH. Genotypes in methylenetetrahydrofolate reductase (MTHFR677C>T), tandem repeat polymorphism in thymidylate synthase enhancer region (TSER) and folylpoly-gamma-glutamate synthetase (FPGS1901T>C) were determined by RFLP or pyrosequencing.
