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.
Cardiovascular disease represents a considerable economic burden to society and effective preventive measures are necessary. Patients with peripheral arterial disease (PAD) have a severe impairment of functional ability, namely in walking distance due to muscle ischemia defined as intermittent claudication (IC). The discomfort related to IC contributes to a sedentary lifestyle, decreasing physical fitness level, aggravating cardiovascular risk factors leading to disease deterioration. Exercise programs are an effective, low-cost, low-risk option compared with more invasive therapies for IC. Home-based exercise therapy (HBET) is structured, unsupervised, self-directed programs that take place in the personal setting of the patient rather than in a clinical setting. HBET program implementation is feasible and eliminates barriers such as transportation issues, proximity to clinics, and conflicts with occupational responsibilities. Even though these programs have shown to be effective at improving walking performance and distance, their results fall below those seen in Supervised Exercise Therapy (SET) programs. Thus, innovative home-based walking programs need to be developed in order to improve results and make exercise therapy available to a larger percentage of the population. The use of Information and communication technology (ICT) tools for self-monitoring is considered key to change long-term behavior. The WalkingPAD project aims to develop health technology assessment methods and evaluate personal health intervention strategies. Investigators intend to demonstrate the technical feasibility and economic viability of a personalized medicine application in real-life healthcare settings. This project intends to find evidence for three major questions: Does an M-health monitored home-based exercise program supported by a virtual assistant empowers commitment to exercise plan and allows remote control of plan accomplishment? Is it superior to an M-health monitored home-based exercise program supported by a behavioral motivational intervention, in increasing maximum walking distance? Is it superior to a self-monitoring exercise, with a specific self-designed walking plan in the residence area, in increasing maximum walking distance?
Current guidelines recommend resection and histopathological analyses of all colorectal polyps. Real-time optical diagnosis can obviate non-neoplastic polyp resection ("diagnose-and-leave-behind") and histopathological analyses of diminutive polyps ("predict-resect-and-discard") reducing healthcare and cost burden. The investigators aimed to evaluate the diagnostic accuracy of computer-aided diagnosis using CAD EYE® (Fujifilm,Germany) in real-time optical characterization of colorectal polyps compared to endoscopic diagnosis with histopathology as the gold-standard. For this purpose, a single-centre prospective study of diminutive/small colorectal polyps is ongoing.
PBFT02 is a gene therapy for frontotemporal dementia intended to deliver a functional copy of the GRN gene to the brain. This study will assess the safety, tolerability and efficacy of this treatment in patients with frontotemporal dementia and mutations in the progranulin gene (FTD-GRN).
The primary objective of this study is to evaluate whether remdesivir (RDV, GS-5734™) reduces the composite risk of death or invasive mechanical ventilation (IMV) through Day 29 in participants with severely reduced kidney function who are hospitalized for coronavirus disease 2019 (COVID-19).
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in patients with macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO).
This study will evaluate the efficacy, safety and patient-reported outcomes of trastuzumab emtansine plus atezolizumab compared with trastuzumab emtansine plus placebo in participants with HER2-positive and PD-L1-positive LABC or MBC.Participants must have progressed either during or after prior trastuzumab- (+/- pertuzumab) and taxane-based therapy for LABC/MBC; or during (or within 6 months after completing) trastuzumab- (+/-pertuzumab) and taxane-based therapy in the neoadjuvant and/or adjuvant setting.
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in participants with macular edema due to branch retinal vein occlusion (BRVO).
This is open-label, multicenter, international study, assessing the efficacy and safety of Trastuzumab deruxtecan (T-DXd) in participants with or without brain metastasis (BMs), with previously-treated advanced/metastatic HER2-positive breast cancer whose disease has progressed on prior anti-HER2-based regimens and who received no more than 2 lines/regimens of therapy in the metastatic setting (excluding tucatinib).
The goal is to assess inter- and intraindividual variation in response to different warm-up protocols in a randomized, cross-over study with U16 and U17 Portuguese soccer players.
Despite the literature evidence that the "balloon-blowing exercise" improves the pulmonary function as a long-term effect, this exercise has not yet been studied or tested experimentally, meaning that there are no specific and measurable results that attest the improvement on thoracoabdominal movement.
