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 main purpose of this study is to describe the safety and tolerability of 80 weeks of subcutaneous (SC) evolocumab when added to standard of care in children 10 to 17 years of age with familial hypercholesterolemia.
This study is being done to see if tucatinib works better than placebo to help patients who have a specific type of breast cancer called HER2 positive breast carcinoma. The breast cancer in this study is either metastatic (spread into other parts of the body) or cannot be removed completely with surgery. All patients in the study will get capecitabine and trastuzumab, two drugs that are often used to treat this cancer. There are two parts to this study. The first part of the study is already complete. Patients were randomly assigned to get either tucatinib or placebo (a pill with no medicine). Since this part was "blinded," neither patients nor their doctors knew whether a patient got tucatinib or placebo. The second part of the study is called the Unblinded Phase. In this part of the study, participants and their doctors know which drugs are being given. Participants who used to get or are currently getting placebo may be able to start taking tucatinib instead. Each treatment cycle lasts 21 days. Patients will swallow tucatinib pills two times every day. They will swallow capecitabine pills two times a day during the first two weeks of each cycle. Patients will get trastuzumab injections from the study site staff on the first day of every cycle.
The main aim of this study is to evaluate the bioavailability of blackberry juice anthocyanins, with or without ethanol, in normal weight and overweight/obese adults.
It is well known that insufficient iodine intakes impairs the production of thyroid hormones, essential for cognitive development and healthy growth. Although the World Health Organization (WHO) promotes public health measures for an adequate iodine consumption, it is estimated that one in three school age children remain iodine deficient worldwide. Whereas there is no mandatory iodisation programs in Portugal, young infants are among the most vulnerable to iodine deficiency due to their special requirements. Therefore, the present study aims to evaluate iodine status in school age Portuguese children (6-12y), compare iodine status in children, cognitive outcomes and thyroid health and monitor the use of iodised salt in school canteens exploring potential implications in children's iodine status.
Recent evidence showed that undergraduate students have inappropriate knowledge about reproductive health and infertility. The investigators' aim was to assess the effectiveness of a brief intervention (video) in increasing the knowledge regarding fertility issues, fertility risk factors and infertility definition.
This is a multicenter, randomized, double-blind study of the efficacy and safety of iclaprim compared to vancomycin for the treatment of skin and skin structure infections.
This randomized active-controlled multicenter Phase III open-label study will evaluate and compare between treatment groups the efficacy of alectinib versus chemotherapy in participants with ALK-positive advanced NSCLC who were previously treated with chemotherapy and crizotinib, as measured by investigator-assessed progression-free survival (PFS) and to evaluate and compare between treatment groups the central nervous system (CNS) objective response rate (C-ORR) in participants with measurable CNS metastases at baseline, as assessed by an Independent Review Committee (IRC).
The main purpose of this study is to compare maintenance treatment with avelumab plus best supportive care (BSC) with BSC alone, to determine if avelumab has an effect on survival in patients with locally advanced or metastatic urothelial cancer that did not worsen during or following completion of first-line chemotherapy.
Systemic Sclerosis (SSc) is a devastating disease of unknown etiology. Patients suffer from multiple organ fibrosis whereas lung fibrosis (interstitial lung disease, ILD) is one of the main driver for mortality. There is preclinical evidence for efficacy of nintedanib in SSc and associated ILD (SSc-ILD) and the anti-fibrotic efficacy of nintedanib was proven in idiopathic pulmonary fibrosis patients, who are presenting a similar pattern regarding lung fibrosis. Hence it is the purpose of the trial to confirm the efficacy and safety of nintedanib 150 mg bid in treating patients with SSc-ILD, compared with placebo. The trial will be conducted as a double blind, randomised, placebo-controlled trial with primary efficacy evaluation at week 52 and placebo-controlled treatment until last patient out (up to a maximum of 100 weeks). Respiratory function is globally accepted for assessment of treatment effects in patients with lung fibrosis. The chosen endpoint (Forced Vital Capacity (FVC) decline) is easy to obtain and is part of the usual examinations done in patients with SSc-ILD.
The aim of this non-interventional study is to describe patient's perception of anticoagulant treatment when using Pradaxa® to prevent stroke and systemic embolism while suffering from atrial fibrillation (according to its approved indication in the approved dosages of 110 mg or 150 mg twice daily) in comparison to standard care using Vitamin K Antagonist (VKA).
