There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
COMPASS-2 is a Phase 4, prospective, randomized, double-blind, placebo-controlled, event-driven study evaluating the effect of bosentan on the time to first confirmed morbidity/mortality event in patients with symptomatic PAH already receiving sildenafil therapy. Patients must have been receiving doses of sildenafil equal to or greater than 20 mg t.i.d. for at least 12 weeks prior to being randomized. The study continued until the predefined target number of morbidity/mortality events was reached.
The purpose of this study is to determine whether rasburicase is effective and safety in correcting hyperuricemia.
To evaluate the dose-response relationship of AVE0010 administered once daily and twice daily with chronic dosing in metformin-treated subjects with type 2 diabetes
The aim of the study is to investigate the effect of roflumilast on exacerbation rate and pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Roflumilast will be administered orally once daily in the morning at one dose level. The study duration will last up to 56 weeks. The study will provide further data on safety and tolerability of roflumilast. For additional information (for US patients only) see www.COPDSTUDY.net or dial 866-788-2673 (toll free).
The particular aim of this study is the comparison of the diagnostic results of MRA images upon application of Vasovist (gadofosveset), a contrast agent not yet available on the market, with the MRA images upon application of a conventional extracellular contrast agent. A catheter angiography, which will be performed as a routine diagnostic procedure for vascular diseases, will serve as an evaluation standard.
GW433908 (fosamprenavir; FPV)is a pro-drug of amprenavir (APV) which is more water soluble and can be formulated into a tablet with a reduced pill burden (four 700mg tablets of FPV versus sixteen 150mg capsules daily for APV. This study is designed to provide additional information on long term safety and tolerability of FPV containing regimens for those subjects who received FPV in previous GlaxoSmithKline studies.
The purpose of this study is to evaluate the effects of Crestor (rosuvastatin) and (Lipitor) atorvastatin on urinary protein excretion over 1 year in non-diabetes with moderate proteinuria and hypercholesterolaemia.
The purpose of this study is to evaluate the effects of Crestor (rosuvastatin) and (Lipitor) atorvastatin on urinary protein excretion over 1 year in patients with Type 1 or 2 diabetes with moderate proteinuria and hypercholesterolaemia.
This study will determine the relative efficacy and safety of up to 100 days Valcyte prophylaxis relative to up to 200 days Valcyte prophylaxis when given for the prevention of CMV disease in high-risk (D+/R-) kidney allograft recipients. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
The purpose of this trial is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin as needed (pro re nata - prn) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic venous thromboembolism (VTE), following initial treatment (5-10 days) with a parenteral anticoagulant approved for this indication. This trial aims to demonstrate non-inferiority of dabigatran compared with warfarin in patients with acute symptomatic VTE. After achieving non-inferiority, this trial also aims to establish superiority (by means of hierarchical tests) of dabigatran over warfarin.
