Filter by:The purpose of this study is to investigate the effect of vitamin D repletion on disease activity and disability in patients with rheumatoid arthritis. The investigators hypothesize that rheumatoid arthritis (RA) patients with vitamin D deficiency have greater disease activity and disability, compared to RA patients with normal vitamin D levels. The investigators also hypothesize that vitamin D treatment in these deficient patients will result in a decrease in RA disease activity and disability.
This trial will evaluate the 36mm or greater metal head on metal hip system and compare it to the 32mm or 28mm metal head on polyethylene (liner) hip system in patients receiving a primary cementless total hip replacement.
The primary objective of this study is to determine the safety of LX3305 in a dose escalation compared with placebo over 12 weeks in subjects with active rheumatoid arthritis (RA).
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of ISIS CRP Rx and its effects on CRP and other pharmacodynamic measures, versus placebo, in subjects with active rheumatoid arthritis.
This is an open-label, multicenter and observational study in China, which is designed to record the data of RA & AS patients within 52 weeks after rheumatologists decided to prescribe etanercept, and evaluate the safety and efficacy of the treatment. All eligible subjects agreed to be recruited in the study and can withdraw anytime if they choose so. Patients with RA or AS are typically managed by rheumatologists. As this study seeks to record the data of RA & AS patient in etanercept and evaluate the safety and efficacy of the treatment, patients will be recruited from Rheumatic department. Rheumatologist will be asked to build up the database for RA & AS patient surveillance prospectively in outpatient dept, which benefits for the patient treatment outcomes evaluation and clinical management.
Development of glucocorticoid (GC)-induced adrenal insufficiency is a serious adverse effect of GC treatment. It is today not possible to predict this adverse effect. The project aims at investigating a possible individual aspect, which may render subjects more or less sensitive to glucocorticoids, and thereby influence development of GC induced adrenal insufficiency. The hypothesis is that subjects with one or another of the polymorphisms in the GC receptor gene will either have increased or diminished GC sensitivity. This may be responsible for differences in development of GC induced adrenal insufficiency.
This study will treat moderate to severe rheumatoid arthritis with MRC375 (either 75 mg 3 times a day, 150 mg 3 times a day or placebo 3 times a day)in patients 18 years of age or older that can be currently on low doses of methotrexate or can stop treatment of current RA medications to enter the study. Safety of MRC375 will also be evaluated. There are up to 8 clinic visits over 24 weeks.
The Treat to Target Trial is a clinical trial available to new and existing CORRONA (Data Collection Program) sites. Subjects are recruited to participate in this 12 month trial examining outcomes and feasibility of implementing a Treat to Target approach, when compared with a control group of subjects treated with usual care.
The purpose of the study is to assess whether a 6-month treatment with adalimumab added on the treatment with conventional antirheumatic drugs (DMARD) will decrease the number of days on sick leave compared to placebo. In addition, the cost-effectiveness and cost-utility of the intervention compared to the conventional treatment is evaluated, and the patients who benefit most are characterized.
This study will evaluate the potential effect of CP 690,550 on the pharmacokinetics of metformin, a probe drug for organic cationic transport.
