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.
Retinal diseases are currently the leading cause of legal blindness in the developed world. Among these disorders, age-related macular degeneration (AMD) is one of the most prevalent conditions in individuals over 55 years of age. Late AMD, the most severe presentation of the disease, clinically manifests as either geographic atrophy (dry form) or choroidal neovascularization (CNV) (wet form). Although patients with wet AMD only represent 10% of the total cases, CNV is the main and most serious cause of central vision loss. At present, the treatment of wet AMD comprises intraocular injections of certain antiangiogenic agents which act by blocking VEGF (vascular endothelial growth factor). No effective treatment is yet available for dry AMD, though the AREDS (Age-Related Eye Disease Study) has shown that the administration of antioxidant supplements is able to slow progression of the disease. Such vitamin supplements are also indicated in patients who already have severe AMD (both exudative and atrophic) in one eye, since the risk of progression in these cases is high. Recent studies involving new antioxidant and antiangiogenic molecules such as resveratrol, present in grapes and wine, have also revealed great efficacy in slowing the progression of advanced AMD. Hydroxytyrosol is another polyphenol with important antioxidant and antiinflammatory effects in the RPE. Considering the above, the present randomized, multicenter interventional study involving Spanish and Portuguese patients with unilateral wet AMD was designed to compare the effects of two different nutritional supplements: one containing the antioxidants and minerals recommended by the AREDS at doses that can be used in the European Union (Theavit), and the other comprising these same substances plus omega-3 fatty acids (lipidic antioxidant), lutein (pigment protecting against light-induced damage) and resveratrol (antioxidant and antiangiogenic agent) (Retilut).
Lip support plays an important role in facial esthetics, being a relevant factor when realizing full arch implant supported rehabilitations. However, there is a lack of research on the three dimensional impact of such restorations.
The study aims to evaluate a modified antiplatelet therapy associated with Firehawk low-dose rapamycin DES in acute myocardial infarction patients treated with complete revascularization strategy. The modified antiplatelet therapy consists of a reduced duration of Dual Antiplatelet Therapy post procedure (ie. 1 month duration) followed by P2Y12 inhibitor monotherapy for the next 11 months. It is hypothesized that in the setting of clinically stable, low to moderate complexity acute Myocardial Infarction patients, a modern approach combining a stent with high biocompatibility feature, complete revascularization strategy and modified antiplatelet therapy may be associated with similar outcomes, or even a significant benefit compared with guidelines-recommended 12-month DAPT. This benefit could be driven by a reduced risk in significant bleeding events, while keeping a comparable protection against ischemic risk. Enrolled subjects will be randomized in a 1:1 ratio to either cessation of aspirin at 1 months, either continuation of DAPT. Selection of the P2Y12 inhibitor agent is left to investigator judgment but has to be in line with the current ESC guidelines. Subjects treated with the Firehawk or Firehawk Liberty coronary stent will be included in this study.
Study CC-93538-EE-001 is a Phase 3, multicenter, multinational, randomized, double-blind, placebo-controlled induction and maintenance study to evaluate the efficacy and safety of CC- 93538 in adult and adolescent participants with eosinophilic esophagitis (EoE). The study will incorporate a 24-week Induction Phase followed by a 24-week Maintenance Phase. Participants will be randomized at the beginning of the study into 3 treatment arms: - Placebo for Induction and Maintenance - CC-93538 360 mg Subcutaneous (SC) once weekly for Induction followed by 360 mg SC once every other week for Maintenance - CC-93538 360 mg SC once weekly for Induction and Maintenance
The overall goal of this real-world data collection is to assess demographic, clinical characteristics and real-world effectiveness of pediatric neuroblastoma patients treated with lorlatinib through the expanded access program.
The primary objective of this post market clinical follow-up (PMCF) investigation is to confirm the safety and performance of Avance®Solo and Avance®Solo Adapt NPWT Systems in low to moderate exuding chronic wounds when used in accordance with the Instructions for Use, for up to 28 days.
Heads of all psychosomatic, psychiatric and psychological consultation and liaison (C&L) services in acute care hospitals across all participating countries will be contacted and asked to participate in this international cross-sectional online survey. The survey consists of questions about care structures and their utilisation that psychosomatic, psychiatric and psychological C&L services have established in acute hospitals in the context of the COVID 19 pandemic.

This study is open to adults with diabetic kidney disease. The purpose of the study is to find out whether a medicine called BI 685509 improves kidney function. Three different doses of BI 685509 are tested in this study. Participants get either one of the three doses of BI 685509 or placebo. It is decided by chance who gets which BI 685509 dose and who gets placebo. Participants take BI 685509 or placebo as tablets 3 times a day. Placebo tablets look like BI 685509 tablets but do not contain any medicine. Participants continue taking their usual medicine for diabetes and kidney disease throughout the study. Participants are in the study for about 7 months. During this time, they visit the study site about 11 times. Where possible, about 6 of the 11 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Kidney function is assessed based on the analysis of urine samples, which participants collect at home. At the end of the trial the results are compared between the different doses of BI 685509 and placebo. During the study, the doctors also regularly check the general health of the participants.
In December 2019, the first people got infected with COVID-19 in Wuhan, China. Within weeks, this highly infectious disease spread all over the world. Nearly one year later everyone is still trying to battle this disease and facing the consequences it causes. What became clear is that the disease and its severity differs largely between infected people. However, knowledge about who will experience severe COVID-19 and who does not is still unclear. Therefore, the aim of this study is to investigate the prognostic value of certain parameters (mtDNA and CT radiomics signature) for the severity of COVID-19.
