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.
A macular hole is a rupture in the macula. In terms of pathogenesis, as much as 80% are idiopathic (Idiopathic Macular Hole, IMH). The normal incidence of this condition is about 0.17%; however, there is a 10-29% chance of development of a macular hole in the fellow eye of patients suffering from unilateral macular hole. Our hypothesis is that embedded in the topography of the retina is information that can allow for discrimination between healthy eyes and eyes with an increased risk of developing IMH. As such, our work aims to develop a system that allows the automatic identification of these eyes.
This study evaluates the safety and tolerability of extended dosing with IONIS-TTR Rx in patients with Familial Amyloid Polyneuropathy.
This multicenter, open-label, phase 3 extension study will investigate the safety and efficacy of rVIII-SingleChain for prophylaxis and on-demand treatment of bleeding episodes in at least 200 previously treated patients (PTPs) with severe congenital hemophilia A and previous exposure to FVIII products who achieve at least 100 exposure days (EDs) to rVIII-SingleChain in this study, as well as in previously untreated patients (PUPs) with no previous exposure to any FVIII product who achieve at least 50 EDs to rVIII-SingleChain in this study. A substudy (open to both PTPs and PUPs) will investigate the use of rVIII-SingleChain in surgery. A substudy (open to PUPs who develop an inhibitor to rVIII-SingleChain) will investigate the use of rVIII-SingleChain in immune tolerance induction (ITI) therapy.
The purpose of this study is to investigate the effects of multiple-dose administration of BIA 2-093 on the steady-state pharmacokinetics of digoxin in healthy subjects.
The purpose of this study is to investigate the effect of food on the pharmacokinetics of a single 800 mg oral dose of BIA 2-093 in healthy volunteers.
The purpose of this study is to determine the efficacy of BIA 2 093 in the treatment of epileptic patients with refractory simple or complex partial seizures with or without secondary generalization.
To investigate the effect of three single oral doses of BIA 9-1067 (25 mg, 50 mg and 100 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled-release levodopa 100 mg/benserazide 25 mg (Madopar HBS).
The purpose of this study is to investigate CYP2C9 inhibition by BIA 9-1067 through the assessment of its effect on the pharmacokinetics of S-warfarin, a substrate of CYP2C9.
It has been demonstrated the application of noninvasive positive pressure ventilation (NPPV) to assist spontaneous breathing through a face mask during fiberoptic bronchoscopy (FOB) with bronchoalveolar lavage (BAL) in severely hypoxemic, nonintubated patients. With NPPV, FOB was well-tolerated, significantly improved the PaO2/FiO2 ratio, and successfully avoided the need for endotracheal intubation. Two randomized studies have provided supporting evidence that the application of NPPV or CPAP via a face mask was superior to oxygen supplementation alone during FOB. For this reason patients who require FOB and are hypoxemic and/or mild hypercapnic (TcCO2 < 60mmHg) will be compared in a randomized study by comparing NPPV vs CPAP Boussignac (Vygon) delivered through a face mask.
The objectives of this registry are to 1. Collect clinical data on Boston Scientific's ImageReady MR Conditional Pacing Systems involving the INGEVITY lead based on observations / events 2. Gather data on actual number of MRI scans performed in the patient cohort implanted with an ImageReady system including information about scanned body parts. 3. Collect physician feedback on lead handling with the INGEVITY lead in a real-life, market-released standard of care environment using devices on intended purpose and which are authorized to bear the CE (Communauté Européenne) marking / are approved for use in the applicable area of participating centers. No additional invasive or other burdensome examinations are to be carried out other than the ones conducted by the centers per their general standard of care.
