Filter by:This is a Phase I multicenter study that will be conducted in the United States and consists of a double-blind, placebo-controlled, SAD stage, followed by a double-blind, placebo controlled MAD stage. The study will be conducted in approximately 65 adult patients between 18 and 80 years old who have RA.
The treatment of rheumatoid arthritis has improved considerably in recent years with the understanding that better outcomes can be achieved by optimising the dosage schedule of conventional drugs that suppress the inflammatory response in joints. Furthermore, the development of protein based drugs that are given parenterally (i.e. by subcutaneous injection or intravenous infusion), known as biologics, have given rise to even better clinical results. However, despite this over 60% of patients with rheumatoid arthritis can still be expected to have an unacceptably high degree of disease activity and the prohibitively high cost of biologic therapy has resulted in rationing following NICE review. Therefore there is a need for more effective and less costly treatment. The proposed study is designed to test potential drug interactions between one such candidate oral treatment, tranilast, and the gold standard therapy for rheumatoid arthritis, methotrexate, which is given as a once weekly oral, intramuscular or intradermal regimen. The drug to be tested, tranilast, an analogue of a naturally occurring molecule that regulates inflammatory responses, is currently used in the treatment of allergic inflammation and has recently been shown to be effective in an animal model of multiple sclerosis. Tranilast is an analogue of a naturally tryptophan metabolite. Laboratory studies of cell biology indicate that this molecule inhibits a number of key inflammatory pathways and the function of white blood cells that play a critical role in the inflammatory features of rheumatoid arthritis. The aim of this study is to assess whether tranilast may be useful for the treatment of RA. In an animal model of rheumatoid arthritis, initial assessment showed that prophylactic administration of tranilast interfered with the development of disease. Therapeutically, in an animal model of arthritis, tranilast was very effective, and reduced all aspects of the disease, including joint swelling, clinical score, and histological damage in a dose−dependent fashion, and reduced pain. This degree of benefit compares well with therapeutics that have been highly successful in humans, such as anti−TNF therapy. Furthermore studies at the Kennedy Institute of Rheumatology Division, Imperial College suggest that tranilast has a greater analgesic effect than the potent steroid dexamethasone at effective anti−inflammatory doses
This is a Phase IIIb multicenter study to evaluate the safety and efficacy of certolizumab pegol (CZP) administered to patients with moderate-to-severe rheumatoid arthritis.
Patients with rheumatoid arthritis who have been well controlled with methotrexate plus infliximab may remain in remission or low disease activity without infliximab. And the chance of sustained remission increase by the addition of another DMARD, bucillamine, at the time of discontinuing infliximab. The BuSHIDO trial is the prospective, randomized, controlled study comparing MTX monotherapy and MTX plus bucillamine combination therapy as to the rate of disease flare after discontinuing infliximab.
The purpose of this study is to assess the effectiveness of treatment in patients with active rheumatoid arthritis who are having an inadequate response to at least 3 months of treatment with etanercept or adalimumab in addition to methotrexate.
This study is being carried out to investigate if AZD5672 is effective in treating Rheumatoid Arthritis (RA) and if so how it compares to placebo (a substance which does not have any action) and etanercept (a medicine already available to treat Rheumatoid Arthritis) when added to treatment with methotrexate. The purpose of this study is also to find out which dose of AZD5672 is the most effective at treating RA and to find out how well the body tolerates AZD5672 when taken for up to 12 weeks.
The purpose of this pilot, exploratory study is to evaluate the safety, tolerance, pharmacokinetics and potential anti-inflammatory activity of an investigational agent, HE3286, when administered orally for 29 days to patients with rheumatoid arthritis that are taking a stable dose of methotrexate.
The purpose of this study is to determine how the body breaks down and excretes the investigational drug, AZD5672.
To assess comparative radiographic efficacy, clinical efficacy and safety of etanercept (ETN) + methotrexate (MTX) with usual disease-modifying anti-rheumatic drug (DMARD) treatment in subjects with moderate RA who were treated with MTX monotherapy, but continue to have moderate disease activity.
This 14-week non-interventional study will observe patients with rheumatoid arthritis (RA) who are being treated with infliximab for the first time, in order to learn about their disease characteristics. Patients in this study will be treated for RA with infliximab and in a usual manner as decided by their physician.
