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 will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of diabetic macular edema.
This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of macular edema associated with retinal vein occlusion.
This is an open-label multi-center Registry in patients with hemophilia B receiving BeneFIX. All patients who begin treatment with BeneFIX in European Union countries, will be eligible for participation. Patient demographics will be collected at baseline for all patients. A baseline FIX activity and Bethesda assay for inhibitor based on historical data should be recorded if available. Adverse events as defined in the protocol will also be reported on the appropriate forms. Data will be collected from patients on an ongoing basis to ensure that information is being captured for each patient being treated with BeneFIX.
Bronchial asthma is among the world's most prevalent diseases. Roflumilast is a novel, orally active, selective enzyme inhibitor (phosphodiesterase 4 inhibitor), which has shown effectiveness in the treatment of asthma. The aim of the study is to investigate the effect of roflumilast taken orally together with low dose inhaled corticosteroids on lung function. Roflumilast will be administered at one dose level once daily together with inhaled corticosteroids at one dose level twice daily. The study duration consists of a baseline period (2 to 6 weeks) and a treatment period (24 weeks). The study will provide further data on safety, tolerability, and effectiveness of roflumilast.
The aim of the study is to compare the efficacy of ciclesonide versus fluticasone propionate on lung function, symptoms, and use of rescue medication in children with persistent asthma. Ciclesonide will be inhaled once daily, using one of the two dose levels; fluticasone propionate will be inhaled at one dose level twice daily. The study duration consists of a baseline period (2 to 4 weeks) and a treatment period (12 weeks). The study will provide further data on safety and tolerability of ciclesonide.
The purpose of this clinical research study is to compare up to 3 doses of an investigational drug GW501516 to placebo (an inactive pill that looks like GW501516) to see if it is safe, well tolerated and effective in improving (raising) low levels of "good cholesterol", high-density lipoprotein cholesterol (HDLc), as compared to placebo.
The Ongoing Telmisartan Alone and in combination wiht Ramipril Global Endpoint trial (ONTARGET): The primary objectives are to determine if (a) telmisartan 80mg daily and ramipril 10mg daily combination therapy is more effective in reducing the composite endpoint of Cardiovascular Death (CV) death, Myocardial infarction (MI), stroke or hospitalization for Congestive Heart Failure (CHF) compared with ramipril 10mg alone; and (b) telmisartan 80mg daily is at least as effective as (i.e. not less effective than) ramipril 10mg daily, on this endpoint. Telmisartan Randomised Assessment Study in Angiotension converting Enzyme inhibitor intolerant subjects with Cardiovascular Disease. (TRANSCEND): The primary objective of the study is to determine if treatment with telmisartan 80mg daily is superior to placebo reducing the composite endpoint of Cardiovascular Death (CV), Myocardial Infarction ( MI)I, stroke or hospitalization for Congestive Heart Failure (CHF) in patients who are intolerant to Angiotension Converting Enzyme inhibitors.
The purpose of the trial is to determine if extended-release dipyridamole + aspirin [Aggrenox, Asasa ntin] is superior to clopidogrel [Plavix], and if telmisartan [Micardis, Gliosartan, Kinzal, Kinzalm ono, Predxal, Pritor, Samertan, Telmisartan] is superior to placebo, in the presence of background antihypertensive therapy, in prevention of a second stroke in patients who have recently suffered a stroke and therefore are at high risk of suffering another one.
To collect additional confirmatory data on alteplase(rt-PA) in the European setting and to demonstrate that the treatment of patients between 3 and 4.30 hours of onset of symptoms of acute ischemic stroke with rt-PA compared to placebo-treated patients will result in an improved clinical outcome without increase of fatality rate.
The general aim of this study is to compare telmisartan 80 mg with valsartan 160 mg in hypertensive patients with type 2 diabetes and overt nephropathy with adjusted blood pressure beyond the target of 130/80 mmHg after one year of treatment. The primary objective of this study is to show that telmisartan 80 mg is at least as effective (i.e., not inferior) and possibly superior to valsartan 160 mg in reducing 24 hour proteinuria after one year of treatment.
