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.
Until now, neuropsychological interventions aimed to optimize cognitive function and to have functional impact in individuals at risk of AD (MCI patients) were scarce in validity studies. While some RCTs have been developed in cognitive training interventions, comparative studies of merged interventions (cognitive, social and behavioral stimulation) with adequate control groups are absent, diminishing the professionals' trust on the adoption of these interventions for supporting patients. As such, the present proposal will develop a validation trial testing a multicomponent neuropsychological intervention (REMINDER), based on personal development, cognitive compensatory aids, meaningful goals setting, and behavior change techniques. The investigators will analyze its short/long-term gains and AD conversion rates. By aiming to provide a good validation study for REMINDER, the investigators will examine neurobiological, neurocognitive and functional outcomes of this intervention in comparison with an active control group (psychoeducation) in order to foster an effective outcome assessment of an intervention for individuals at risk of AD.
This Phase III, randomized, two-arm, open-label, multicenter study will evaluate the efficacy and safety of giredestrant plus Phesgo compared with Phesgo after induction therapy with Phesgo plus taxane in participants with human epidermal growth factor receptor 2 (HER2)-positive, estrogen receptor (ER)-positive advanced breast cancer (metastatic or locally advanced disease not amenable to curative treatment) who have not previously received a systemic non-hormonal anti-cancer therapy in the advanced setting.
This is an open-label, multicenter international trial in men and women with primary operable HR+/HER2-, ki67≥20%, grade 2 or 3 and stage II breast cancer to evaluate safety and long-term efficacy of a non-chemo treatment in patients biologically responders to neoadjuvant ribociclib and letrozole. This study aims to evaluate whether chemotherapy could be avoided for initial high-risk clinicopathological breast cancer patients that are converted to low genomic risk assessed by Risk of Recurrence-low (ROR-low) at 6 months of letrozole - ribociclib neoadjuvant treatment by continuing with this treatment in adjuvant setting.
The present study aims at analyzing the dose-response effects of a recreational team handball-based exercise programme on cardiovascular, metabolic, musculoskeletal and physical fitness markers of inactive middle-aged and older men, without previous experience with the sport. The researchers hypothesized a positive weekly training frequency effect on health and physical fitness outcomes.
This study aimed at determining the short- (16 weeks) and long-term (36 weeks) health and physical fitness effects and adherence of recreational team handball training for postmenopausal women without previous experience with the sport. The investigators hypothesized that short-term recreational team handball training would result in positive health and physical fitness adaptations and that the health and physical fitness improvements achieved after the first 16 weeks would be maintained or further improved at the long-term. Moreover, the investigators also hypothesized that the adherence to this exercise mode would be maintained throughout the 36 weeks (long-term) compared to the first 16 weeks (short-term).
Multicenter, prospective, non-randomized, post-market clinical follow-up (PMCF) study to confirm and support the clinical safety and performance of Navitian to meet EU Medical Device regulation (MDR) requirements in all the CONSECUTIVE patients treated with Navitian.
For this retrospective study, the investigators will collect and analyze data of patients who presented with posterior artery occlusion and underwent mechanical thrombectomy (the type of endovascular stroke treatment) and intravenous thrombolysis (the type of non-endovascular stroke treatment). The electronic health records will be queried for the demographic, medical history, and outcomes data of all patients with posterior cerebral artery occlusion who underwent mechanical thrombectomy, intravenous thrombolysis (IVT), or medical management.
Identify the relationship of obstructive sleep apnea (OSA) prevalence with post-COVID-19 fatigue that remains at least six months after acute disease
The study will include 60 patients awaiting bariatric surgery. They will be randomized into 2 groups, experimental and control. The intervention will take place 1 month after surgery, for a total of 16 weeks. Parameters of body composition, metabolic risk, quality of life, physical activity and sedentary behavior will be determined
The purpose of this study is to evaluate the safety and efficacy of the combination of retifanlimab plus INCAGN02385 and retifanlimab plus INCAGN02385 and INCAGN02390 compared with retifanlimab alone as first-line treatment in PD-L1-positive and systemic therapy-naive recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN).
