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.
This study aimed to investigate the effects of a novel dietary supplement, consisting of melatonin and magnesium in a pod (coffee machine capsule) format, on sleep quality, stress, mood, sleepiness, biological rhythms, metabolism, body composition and performance, in individuals with sleep disturbances according with the Pittsburgh Sleep Quality Index. A randomized, double-blind, crossover trial will be conducted to compare the effects of the melatonin and magnesium-containing supplement against a placebo. The protocol comprises 4 weeks of supplementation with an experimental or placebo condition, with a week-long washout period. Biochemical markers of sleep and stress, actigraphy for sleep patterns and sleep hygiene, resting metabolic rate, food and fluid intake, body composition, and handgrip strength measures will be evaluated at baseline and 4 weeks post each randomly assigned intervention. The working hypothesis is that this innovative supplement will provide greater objective and subjective improvements regarding sleep patterns and quality, overall mood, biochemical markers of stress, resting metabolic rate, energy intake, body composition and strength, than the placebo comparator, due to the synergic effects of melatonin and magnesium.
A global, multi-center, Disease Monitoring Study (DMS) in participants with Autosomal Dominant Hypocalcemia Type 1 (ADH1) or Autosomal Dominant Hypocalcemia Type 2 (ADH2) designed to characterize ADH1 and ADH2 disease presentation and progression through retrospective (past) and longitudinal prospective (over time into the future) data collection.
Multinational, prospective, proof of concept phase II, double-blinded, sham-controlled, randomized clinical trial (RCT) to evaluate the efficacy and safety of Remote Ischaemic PreConditioning (RIPC) in Lymphoma patients receiving anthracyclines.
This is a Phase III, randomised, double-blind, multicentre, international study assessing the efficacy and safety of durvalumab (MEDI4736) in combination with oleclumab (MEDI9447) or durvalumab (MEDI4736) with monalizumab (IPH2201) in adults with locally advanced (Stage III), unresectable NSCLC, who have not progressed following platinum-based cCRT.
The primary objective is to evaluate the efficacy of carisbamate (YKP509) as adjunctive treatment in reducing the number of drop seizures (tonic, atonic, and tonic-clonic) compared with placebo in pediatric and adult subjects (age 4-55 years) diagnosed with Lennox Gastaut Syndrome (LGS).
This study is designed to assess the efficacy and safety of datopotamab deruxtecan (Dato-DXd) in combination with pembrolizumab versus pembrolizumab alone in participants with advanced or metastatic non-small cell lung cancer (NSCLC).
The study is designed to evaluate the safety and efficacy of rusfertide in subjects with polycythemia vera (PV) in maintaining hematocrit control and in improving symptoms of PV.
HARMONIA is an international, multicenter, randomized, open-label and phase III study. The primary objective of this study is to demonstrate that the combination of ribociclib with endocrine therapy (letrozole or fulvestrant) is superior to palbociclib with endocrine therapy (letrozole or fulvestrant) in prolonging progression-free survival in patients with advanced HR+/HER2- and HER2-E breast cancer. The study will enroll approximately 456 patients with HER2-E disease from approximately 95 sites worldwide. In addition, the HARMONIA trial will include an exploratory cohort of patients with HR+/HER2- and Basal-like disease treated with paclitaxel +/- Tislelizumab. This cohort does not have a predefined sample size and the objective is only exploratory, given the suggested lack of efficacy of the combinations of hormone therapy and CDK4/6 inhibitors in this subgroup of patients. Enrolment into the basal-like cohort will stop once the HER2-E disease cohort is fully enrolled.
The purpose of this clinical trial (called the FLOTILLA study) is to give continued access to the study medicines, as well as safety follow-up, for participants in prior clinical trials of encorafenib and/or binimetinib. All participants who took part in earlier encorafenib and/or binimetinib studies may participate the FLOTILLA study if they are still benefiting from the use of the study medicines. This will be determined by the study doctor. People may not participate in the FLOTILLA study if they have not enrolled in a prior study of encorafenib or binimetinib. Participants that had enrolled but had stopped receiving the study treatment in a prior study cannot enrolled in this study. Participants in the FLOTILLA study will receive encorafenib and/or binimetinib at the same dose and frequency as in their prior study, for up to about 5 years.
Autoinflammatory diseases (AID) are clinical entities characterized by recurrent inflammatory attacks in absence of infection, neoplasm or deregulation of the adaptive immune system. Among them, hereditary periodic syndromes, also known as monogenic AID, represent the prototype of this disease group, caused by mutations in genes involved in the regulation of innate immunity, inflammation and cell death. Based on recent experimental acquisitions in the field of monogenic AID, several immunologic disorders have been reclassified as polygenic/multifactorial AID, sharing pathogenetic and clinical features with hereditary periodic fevers. This has paved the way to new treatment targets for patients suffering from rare diseases of unknown origin, including Behçet's disease, Still disease, Schnitzler's disease, PFAPA (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) syndrome, chronic recurrent multifocal osteomyelitis (CRMO), non-infectious uveitis and scleritis. Gathering information on such rare conditions is made difficult by the small number of patients, along with the difficulty of obtaining an accurate diagnosis in non-specialized clinical settings. In this context, the AIDA project promotes international collaboration among clinical centres to develop a permanent registry aimed at collecting demographic, genetic, clinical and therapeutic data of patients affected by monogenic and polygenic AID, in order to expand the current knowledge of these rare conditions.
