There are about 3194 clinical studies being (or have been) conducted in Portugal. 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 study was designed to characterize dose response, and evaluate safety and efficacy of three different doses of EMA401 compared to placebo in patients with post-herpetic neuralgia (PHN).
The purpose of the study was to To investigate whether the administration of BIA 6-512 (25 mg, 50 mg, 75 mg and 100 mg) at steady-state affects the pharmacokinetics of levodopa when administered in combination with a single-dose of immediate release levodopa/benserazide 200/50 mg or with a single-dose of immediate release levodopa/benserazide 200/50 mg plus a single-dose of entacapone 200 mg.
The objective of the trial was to investigate the effect of the use of inhaled CMS, administered b.i.d. via a specific nebuliser for 12 months, compared to placebo in subjects with NCFB chronically infected with P. aeruginosa on the annualised frequency of pulmonary exacerbations.
To investigate the tolerability and safety of four multiple-dose regimens of BIA 6-512 (25 mg, 50 mg, 100 mg, and 150 mg 6 times daily) in healthy volunteers and to characterise the steady-state pharmacokinetic profiles of BIA 6-512 (25 mg, 50 mg, 100 mg, and 150 mg 6 times daily) in healthy volunteers.
To investigate the effect of rising oral single-doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) on levodopa pharmacokinetics when administered in combination with a single-dose of immediate release levodopa/carbidopa 100/25 mg (Sinemet® 100/25) or with a single-dose of Sinemet® 100/25 plus a single-dose of entacapone (Comtan®) 200 mg and to assess the tolerability and safety of rising single oral doses of BIA 6-512 when administered in combination with a single-dose of Sinemet® 100/25 or with a single-dose of Sinemet® 100/25 plus a single-dose of Comtan® 200 mg.
To investigate the effect of four single oral doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) on levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa/benserazide 100/25 mg and to assess the tolerability and safety of four single oral doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) when administered in combination with a single-dose of controlled release levodopa/benserazide 100/25 mg.
The main purpose of this study is to assess whether exercise training reduces ambulatory blood pressure in patients with resistant hypertension. To accomplish these goals 60 patients with resistant hypertension will be recruited and randomized into exercise training or control groups and followed up for 6 months. The patients in the exercise group will participate in a 3-month outpatient program. The control group will receive usual medical care. At baseline, after the intervention and 3 months after the end of the intervention both groups will undergo several evaluations, including casual and ambulatory blood pressure, body composition, cardiorespiratory fitness, quality of life, arterial stiffness, autonomic function, and endothelial and inflammatory biomarkers.
The Clover trial is evaluating an investigational vaccine that may help to prevent Clostridium difficile infection. Participants in the study are adults 50 years of age and older, who are at risk of developing Clostridium difficile infection. The study will assess whether the vaccine prevents the disease, and whether it is safe and well tolerated. Each subject will receive 3 doses of Clostridium difficile vaccine or placebo and be followed for up to 3 years after vaccination for potential Clostridium difficile infection.
A Phase 3b, single arm, open-label, multicenter study in treatment naïve adults with chronic HCV infection and compensated cirrhosis to assess the safety of 8 weeks of treatment with glecaprevir/pibrentasvir and to demonstrate the efficacy of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with glecaprevir/pibrentasvir compared to the historical SVR12 rates of 12 weeks of treatment with glecaprevir/pibrentasvir.
The study objective of Period 1 was to compare the safety and efficacy of upadacitinib 15 mg once daily (QD) to abatacept on a background of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) for the treatment of signs and symptoms of rheumatoid arthritis (RA) in biologic disease-modifying antirheumatic drug (bDMARD)-inadequate response or bDMARD-intolerant participants with moderately to severely active RA. The study objective of Period 2 is to evaluate the long-term safety, tolerability, and efficacy of upadacitinib 15 mg QD in participants with RA who had completed Period 1.
