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.
This single arm study will assess the safety of MabThera plus methotrexate in patients with rheumatoid arthritis who have had a lack of response to 1-5 DMARDs or biological agents. Patients will receive MabThera (1g i.v.) on days 1 and 15, concomitantly with methotrexate >=15mg p.o./week. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
This 5 arm study will assess the efficacy, pharmacokinetics, safety and tolerability of a DPP-IV inhibitor compared to placebo in patients with type 2 diabetes. Patients will be randomized to receive DPP-IV(3) at one of 4 doses (of 12.5mg and above), or placebo p.o. Patients receiving metformin before the study will continue on the same dose of metformin. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
The purpose of the present study was to evaluate the effectiveness of a nighttime positioning hand splint in patients with RA in terms of pain, grip and pinch strength, upper limb function, quality of life, and patient satisfaction. The hypothesis is that the stabilization of hand during nighttime could decrease pain and consequently improve quality of life.
The primary objective of the study is to determine the efficacy of ramipril in preventing a urinary protein to creatinine ratio (U p/c) greater than 0.5 following conversion to sirolimus from a calcineurin inhibitor (CNI) in maintenance kidney transplant patients.
1) To evaluate the effectiveness of AST-120 (spherical carbon adsorbent) added to standard-of-care therapy in moderate to severe Chronic Kidney Disease (CKD), on time to first occurrence of any event of the triple composite outcome of initiation of dialysis, kidney transplant or doubling of serum creatinine (sCr) when compared with placebo; 2) To evaluate the safety and tolerability of long-term AST-120 therapy in patients with CKD; 3) To evaluate the effects of AST-120 versus placebo, on other measures of renal function and quality of life.
Dietary magnesium (Mg) intake has been shown to be independently related to lung function, airway reactivity, and respiratory symptoms in the general population. Inhaled Mg and IV Mg administration have been shown to promote bronchodilation and to improve lung function in asthmatic patients. Some studies have suggested that COPD patients exhibit decreased body levels of Mg. The purpose of the present study was to investigate the effects of acute IV Mg loading on parameters of respiratory function and maximal exercise capacity of stable COPD patients.The study hypothesis is that Mg administration will be associated to improvements on airflow and vasodilation leading to improvements of pulmonary function and exercise performance.

The purpose of this study is to investigate the effects of the practice of singing for a long period of time on pulmonary function data, quality of life, and dyspnea sensation of patients with COPD in stable clinical conditions. As singing is a type of respiratory training, the study hypothesis is that singing would improve maximal respiratory pressures, dyspnea sensation, and overall quality of life of these patients.
Melasma is an acquired, symmetric, irregular hypermelanosis on sun-exposed areas of the face, commonly seen in Latin American women. It is a very frequent disease, although its true incidence is unknown. Melasma has historically been difficult to treat and therapy remains a challenge for this chronic condition. Melasma being a relapsing disease, there is a real need to address how to maintain efficacy achieved after acute treatment. A previous 12-month trial has shown that Tri-Luma® applied once daily over a long-term period is safe and tolerable. However, there are no robust data available either on the efficacy of Tri-Luma® in long-term treatment or guidance for a maintenance dosage regimen with this product. Investigations have been made through a feasibility work among Dermatologists from USA and Latin America to assess their current practice in terms of Maintenance Therapy. Two regimens appear to be prescribed frequently and will be compared in this study. The expectation is that Tri-Luma® will be effective, in one of the two regimens explored, in maintaining the Melasma improvement achieved with a previous treatment of Tri-Luma®.
The purpose of this 32 week study is to demonstrate that fixed-dose combination treatment with rosiglitazone/metformin will safely and effectively control glycemia as first line oral therapy in subjects type 2 diabetes. The primary objective of the study is to demonstrate superiority of rosiglitazone/metformin compared to its rosiglitazone and metformin.
