Filter by:This study is being conducted to examine the effect of AZD6140 on the levels of certain chemicals in subjects' blood and urine.
The purpose of the study is to evaluate the safety and clinical effect of re-exposure to a 24 week course of treatment of pegloticase i.v. in subjects whose last exposure to pegloticase i.v. was at least one year before study entry. This study is limited to four study centers in the US.
This is a clinical research study to determine the safety and effectiveness of an experimental drug called rilonacept in subjects with gout who are beginning another additional treatment. Subjects will participate in this study for approximately 24 weeks. Rilonacept is being studied for use in preventing gout attacks in patients who have gout.
Radiographic imaging plays a key role in managing the long-term effects of hyperuricemia on the skeletal system. Two of the accepted indications for prophylactic urate-lowering drugs in patients with hyperuricemia are gouty tophi and erosions. While much data exist on the plain radiographic changes that are seen in patients with chronic gout, far less is known about the changes seen on other imaging modalities, such as magnetic resonance imaging (MRI) and ultrasound (US). Further, there is very little data on the MRI and US appearance of asymptomatic joints in patients with hyperuricemia and symptomatic gout. There is vast emerging data to suggest that MRI and US are much more sensitive than plain radiographs at detecting the early stigmata of rheumatoid arthritis (RA). Indeed, these imaging devices have revolutionized the treatment of RA, for the earlier detection of the skeletal changes of RA often mandates more aggressive therapy. These same changes would often be missed by plain radiographs. It is our hypothesis that MR imaging and US will detect the skeletal changes that are typical of gout much sooner than would plain radiography. We also hypothesize that these same imaging techniques will be able to detect signs of hyperuricemic silent deposition in asymptomatic joints of patients with symptomatic gout in other joints. As was the case with RA, the expected results of this study would mandate more aggressive therapy of both gout and hyperuricemia. Our primary aim of this proposal would be accomplished by studying patients with known gout and normal plain radiographs. Each patient would have their most frequently involved joint (index joint) analyzed by MRI and US to evaluate for any destructive changes (erosions or tophi with cortical damage). Any signs that may portend future joint destruction such as synovial pannus, bone marrow edema, soft tissue edema, or joint effusions will also be documented. In order to demonstrate the effects of hyperuricemic silent deposition, an asymptomatic joint from these same patients will be studied using these same imaging techniques. Any evidence of erosions, tophi, synovial pannus, bone marrow or soft tissue edema, or joint effusions will be recorded. By demonstrating destructive, or potentially destructive, skeletal changes in the index joint or asymptomatic joint of a significant number of patients, we will show that patients who are left untreated on the basis of normal plain radiographs are likely to already have skeletal damage.
This study is a multicenter, randomized, double-blind, placebo-controlled, parallel group, dose-comparison to determine the efficacy and safety of a standard-dose of colchicine (4.8 mg) versus low-dose colchicine (1.8 mg) or placebo for acute gout flares.
The purpose of this study is to compare the efficacy and safety of febuxostat, once Daily (QD), to allopurinol in subjects with hyperuricemia and gout.
These are two replicate studies to evaluate the safety and efficacy of PEG (polyethylene glycol)-uricase in controlling the uric acid level in symptomatic gout patients with high uric acid levels who are unable to take standard gout therapies, or for whom those therapies have been unsuccessful in controlling their uric acid level.
The purpose of this study is to determine the long-term safety of febuxostat, once daily (QD), compared to allopurinol in reducing serum urate levels in subjects with gout.
The purpose of this study is to determine the inter- and intra-rater reproducibility of direct physical measurement of tophus nodules in subjects with gout.
The purpose of this study is to determine the efficacy of febuxostat, once daily (QD), in reducing serum urate levels in subjects with gout.
