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 multicenter, randomized, open-label, active-controlled Phase 3 study for the maintenance treatment of anemia in participants with dialysis-dependent chronic kidney disease (DD-CKD)
To demonstrate the effectiveness of riociguat as replacement of phosphodiesterase-5 inhibitors (PDE-5i) therapy in pulmonary arterial hypertension (PAH) patients
Connective tissue diseases (CTD) or systemic autoimmune diseases (SADs) as they are known today are a group of chronic inflammatory conditions with autoimmune aetiology with few treatment options and difficult diagnosis.Brest team contribute to perform a new classification of the following systemic autoimmune diseases in a European Union's Seventh Framework Programme. The aim of this research is to constitute a Healthy Volunteers cohort to compare with systemic autoimmune diseases cohort into molecular clusters instead of clinical entities through the determination of molecular profiles using several "Omics" techniques.

The aim of this research is to reclassify the individuals affected by SADs into molecular clusters instead of clinical entities through the determination of molecular profiles using several "Omics" techniques.
The Amulet™ device will be evaluated for safety and efficacy by demonstrating its performance is non-inferior to the commercially available WATCHMAN® left atrial appendage closure device in patients with non-valvular atrial fibrillation. Patients who are eligible for the trial will be randomized to receive either the Amulet device or the WATCHMAN device and will be followed for 5 years after device implant.
The purpose of this multi-center event-driven study in participants with anemia associated with chronic kidney disease (CKD) to evaluate the safety and efficacy of daprodustat.
The purpose of this multi-center event-driven study in non-dialysis (ND) participants with anemia associated with chronic kidney disease (CKD) is to evaluate the safety and efficacy of daprodustat compared to darbepoetin alfa.
Colorectal cancer (CRC) is a leading cause of cancer death and its' incidence is rising in most European countries. Colonoscopy has been shown to reduce CRC incidence, however its effectiveness depends on the sensitivity to detect pre-malignant lesions. Our aim is to evaluate narrow band imaging (NBI) during colonoscopy and serum miRNAs as novel tools for the early detection of colonic sessile serrated lesions (SSL). The investigators will perform a multicenter-randomized-controlled-trial to study the role of NBI in SSL detection.
The main purpose of this study is to compare how long patients with gastric or gastroesophageal junction cancer live after receiving nivolumab and ipilimumab or nivolumab and chemotherapy compared with patients receiving chemotherapy alone.
The purpose of this study is to evaluate the relative effectiveness of two psychological interventions, cognitive-behavioral therapy (CBT) and hypnosis (Hyp), in preventing and managing pain, regulating emotional state and improving quality of life in Portuguese PWH.
