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.
The purpose of the this study is to collect safety and efficacy data on Focused Ultrasound treatment (UCP procedure) in open angle glaucoma patients without previous glaucoma surgery.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
The main purpose of this study is to evaluate the efficacy of the study drug known as lanabecestat in participants with mild Alzheimer's disease (AD) dementia.
To provide access to maraviroc to patients who have limited or no therapeutic treatment options and to collect more safety data in a broader patient population.
Primary Objective: To determine the effect of avalglucosidase alfa treatment on respiratory muscle strength measured by percent (%) predicted forced vital capacity (FVC) in the upright position, as compared to alglucosidase alfa. Secondary Objective: To determine the safety and effect of avalglucosidase alfa treatment on functional endurance (6-minute walk test, inspiratory muscle strength (maximum inspiratory pressure), expiratory muscle strength (maximum expiratory pressure), lower extremity muscle strength (hand-held dynamometry), motor function (Quick Motor Function Test), and health-related quality of life (Short Form-12).
The purpose of this study is to determine whether multiple-dose administration of nebicapone affects the pharmacokinetics of warfarin.
The purpose of this study is to determine the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 100 mg/benserazide 25 mg (Madopar® HBS 125).
Single centre, randomised, open-label, two-way crossover study to investigate whether multiple-dose administration of eslicarbazepine acetate (ESL, BIA 2-093) affects the pharmacokinetics of gliclazide.
The primary objective of this study is to evaluate the Carboxipeptidase D (CPD) genotyping as a predictive biomarker of body weight and/or fat mass reduction in obese patients treated with perindopril. There is nonclinical and clinical evidence that a subgroup of human subjects may present a decrease in body weight and/or fat mass following treatment with perindopril. Although the individual characteristics that determine such effect are still unknown, Gene PreDiT SA (Biocant Park, Cantanhede, Portugal) discovered that certain genetic characteristics (e.g., single nucleotide polymorphisms (SNPs) of CPD gene) may play a role and potentially could serve as a potential predictive biomarker of response to perindopril. These promising results, along with the fact that perindopril is a medicine already in use in clinical practice, led Gene PreDiT SA to decide to proceed with the development of a theranostic approach for the treatment of obesity. Such theranostic approach consists on the use of CPD genotyping to identify obese subjects that could present improved body weight and fat mass reduction following treatment with perindopril. The current clinical trial aims to prove the concept and provide data to design further confirmatory studies. Additionally this study will evaluate the association between CPD SNPs genotypes and response to perindopril; the effect of perindopril in waist circumference, waist/hip ratio, and BMI and the tolerability and safety of perindopril in the study population.
The primary objective of this study is to evaluate the efficacy of subcutaneous azacitidine in combination with durvalumab as compared with subcutaneous azacitidine alone in adults with previously untreated, higher risk MDS who are not eligible for HSCT or in adults ≥ 65 years old with previously untreated AML who are not eligible for HSCT, with intermediate or poor cytogenetic risk.
