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 assess the efficacy and safety of vamikibart in participants with uveitic macular edema.
Depression is one of the most common mental disorders in older adults and a major cause of years lived with disability. Depression does not always respond to antidepressants, and non-pharmacological interventions are recommended by international guidelines. The Metacognitive Training for Depression in Later Life (MCT-Silver) is a creative and innovative group intervention that aims to reduce depressive symptoms by challenging the cognitive and metacognitive beliefs characteristic of this disorder, that intends to enable participants to recognize and correct their automatic and dysfunctional thinking patterns and behavior. It was developed by the partner institution's team, and has already demonstrated positive results. This project aims to extend the research study to Portugal, through cultural adaptation, pilot study, and a Randomized Controlled Trial (RCT). To this end, we defined the following aims: To plan and conduct a pilot study to assess the efficacy of the MCT-Silver in the Portuguese population; To conduct a multicenter randomized controlled trial (RCT).
The trial will evaluate efficacy, safety and tolerability of two regimens of ianalumab compared to placebo, given as monthly or quarterly subcutaneous (s.c.) injection on top of standard-of-care (SoC) treatment in participants with active systemic lupus erythematosus (SLE).
This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. Participants will be in the trial for up to 24 weeks, including a screening period lasting up to 8 weeks, a 12-week treatment period, and a 4-week safety follow-up period Participants are not expected to directly benefit from treatment during this trial. Participants will help researchers learn more about and how to develop AZD4831 to treat NASH.
Wear resistance is one of the most important physical properties of teeth, and wear resistance of zirconia against artificial acrylic, enamel and composite resin denture teeth has not been clearly established. Implant-supported dental restorations present a higher threshold for occlusion perception when compared to natural teeth, which can occlusal overload mechanisms or lead to wear of rehabilitation materials or the antagonist arch. In clinical conditions, however, many other factors influence the complex interaction between dental enamel and opposing substrates: patient-related factors such as dietary habits, dysfunctional occlusion, masticatory forces, and bruxism contribute to accelerated enamel loss of antagonist teeth.
This study will be done to see if ziltivekimab can be used to treat people living with heart failure and inflammation. Participants will either get ziltivekimab or placebo. Participants will get study medicine for once-monthly injections either in a pre-filled syringe to inject the study medicine into a skinfold or a pen-injector to inject the study medicine into flat skin. The study is expected to last for up to 4 years. Participants will have up to 20 clinic visits. Participants will have to use a study app on their phone to record and share information about all their injections of study medicine and to fill in questionnaires.
FIBRALUNG is a prospective cohort study with biobank of samples from patients with pulmonary fibrosis, aiming to explore the molecular determinants of different clinical outcomes, acute exacerbations and mortality. We expect to gain deeper insight into fibroproliferative common pathways, particularly between idiopathic pulmonary fibrosis and fibrotic hypersensitivity pneumonitis, paving the way for new biomarkers that reflect the progressive phenotype, that eventually will support new targeted therapies. Other idiopathic interstitial pneumonias, connective tissue disease-related interstitial lung diseases and sarcoidosis patients will be also recruited and their biological samples stored for further analyses.
The goal of this clinical trial is to compare the effects of resistance exercise and endurance in post-bariatric surgery patients with insuficcient weight loss. The main question it aims to answer is: - Is resistance exercise more effective than endurance exercise in preventing obesity relapse in post-bariatric surgery patients with insuficcient weight loss? - Is resistance exercise more effective than endurance exercise in increasing resting metabolic rate in post-bariatric surgery patients with insuficcient weight loss? Participants will be randomly assigned to one of the following groups: - Resistance group: performing resistance exercise-training for 16 weeks - Endurace group: performing endurance exercise-training for 16 weeks - Control group: no intervention / standard medical care
The primary objectives of this study are: 1. To obtain information on the pharmacokinetics of cytisinicline following a single oral dose in subjects with varying degrees of renal impairment relative to matched controls with normal renal function. 2. To investigate the extent of cytisinicline removal by hemodialysis.
A significant influence of the Herpes viruses family in the progression of periodontal disease has been suggested. The aim of this study was to investigate the potential association of four Herpes viruses (HSV-1, HSV-2, CMV and EBV) with periodontal disease using a qualitative test for evaluating the presence or absence of viral DNA in crevicular fluid samples of both healthy periodontal patients and periodontal compromised patients. Adult patients with healthy periodontium or periodontally compromised attending the Egas Moniz university dental clinic (Almada, Portugal) are eligible to participate The study involves a periodontal diagnosis and collection of unstimulated crevicular fluid from saliva samples. There will be no direct benefits for patients, but indirect benefit of advancing science in the study of potential involvment of Herpes viruses in periodontitis. No risks of participating are antecipated as the study material and data will be anonymized. The study runs from the the Cooperativa de Ensino Egas Moniz and is expected to run for 3 months.
