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 this extension study was to evaluate the efficacy and safety of brolucizumab used in a Treat-to-Control-regimen for treatment of patients with neovascular age-related macular degeneration who have completed the CRTH258A2303 (TALON) study. The main objective was to assess brolucizumab's potential for long durability up to 20 weeks. All eligible participants were treated with brolucizumab regardless of their treatment in the TALON study. The study period was 56 weeks including post-treatment follow-up.
Introduction: Coronavirus disease 2019 (COVID-19) is a new pathology, declared a public health emergency by the World Health Organization, which can have negative consequences for pregnant women and their newborns. It is estimated that 1 in 5 women will develop a mental illness in the perinatal period. COVID-19 pandemic has been associated with anxiety and depression in the population. The current pandemic is a unique stressor with potentially wide-ranging consequences in the perinatal period, but little is known about the impact of COVID-19 on perinatal mental health. Thus, the objective of this study is to explore the experiences of pregnant and new mothers during the current pandemic, particularly its impact on perinatal mental health (including depression, anxiety, PTSD and psychological distress). Methods: The study design is a prospective observational study, with a baseline assessment and three follow-ups: one month; three months; and six months post baseline. This international study will be carried out in 11 European countries (Albania, Bulgaria, Cyprus, France, Greece, Israel, Malta, Portugal, Spain, Turkey, United Kingdom) Chile and Brazil. The study population will comprise pregnant women and new mothers with an infant under six months of age, covering a broad range of women across the perinatal period. Ethics and dissemination: The study and handling of the data will follow all national required data protection standards. Each researcher (or team of researchers) involved will submit the project to their local ethical committee before starting the project. Results from the project will be disseminated in peer reviewed journals and international conferences.
The purpose of the study is to evaluate the efficacy of Olezarsen as compared to placebo on the percent change in fasting triglycerides (TG) from baseline.
The purpose of this study is to collect real-world evidence on the performance of the SOLTIVE™ Premium SuperPulsed Laser System for laser lithotripsy in ureteroscopy, percutaneous nephrolithotomy (PCNL) and mini PCNL for kidney and ureteral stones.
The primary objective for this non-interventional study was to assess the quality of life of melanoma patients under adjuvant treatment with dabrafenib and trametinib in real world setting in Portugal through disease specific FACT-M questionnaire and generic EQ-5D-3L questionnaire. The secondary study objectives were to assess the usage of adjuvant dabrafenib and trametinib in clinical practice and to evaluate clinical outcomes in patients that started adjuvant treatment with dabrafenib and trametinib. In addition, this study aimed to explore if treatment discontinuation affects clinical outcomes in real-world practice.
This study will assess if there are microtubule cytoplasmic features specifically associated with oocyte vitrification.
The aim of the study is to determine how well the drug BAY1817080 works in OAB patients with urgency urinary incontinence (UUI), defined as involuntary leakage of urine, accompanied or immediately preceded by a sudden compelling desire to void. BAY1817080 is a new drug under development which blocks proteins expressed on the sensory nerves in the bladder. These nerves seem to overreact in OAB patients. This study will test if the treatment with BAY1817080 will reduce the frequency of OAB symptoms. The frequency of OAB symptoms before the treatment and the frequency after 4, 8 and 12 weeks of treatment will be compared. Another important objective of this study will be the assessment of BAY1817080 safety and tolerability in this patient population. BAY1817080 will be compared to a "placebo". A placebo tablet looks like the study drug but does not have any medicine in it. Using a placebo helps to learn if the study drug works. Each participant is expected to take part in the study for about 5 months (around 20-22 weeks).
Background: Effectiveness of maintenance therapy for COPD with Dry Powder Inhalers (DPIs) requires an optimal Peak Inspiratory Flow Rate (PIFR), a proper inhalation technique and adequate medication adherence from patients. Recent studies have suggested that patients with reduced peak inspiratory flow may have worse COPD-related symptom burden and increased risk of COPD-related hospitalizations. However, in primary care, little is known about how many COPD patients have suboptimal PIFR. Furthermore, there is a paucity of knowledge concerning the associations of PIFR, inhalation technique and medication adherence with the effectiveness of maintenance therapy. Objective: To examine associations of PIFR, inhalation technique, and medication adherence with health status and disease, exacerbations, and healthcare resource utilization in patients with COPD receiving maintenance treatment with dry powder inhalers. Study design: Cross-sectional observational study in five European countries*. Study population: COPD patients aged 40 years or older who have received COPD maintenance therapy through DPIs in the past 3 months or longer. Main study parameters: Health status as measured with the Clinical COPD Questionnaire (CCQ), COPD Assessment Test (CAT), number of exacerbations, an assessment of PIFR, inhalation technique errors, medication adherence, healthcare resource utilization (HCRU), medication use and demographic and clinical covariates. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: No significant burden from participating is expected. Risk of participating is deemed negligible. In addition, patients may benefit from participating. Specifically, patients who manifest inhalation errors, will receive a tailored inhalation instruction to remediate their inhalation errors. The impact of this instruction will not be evaluated in any way, therefore it should not be seen as an intervention. * If the preplanned number of patients cannot be included also because of national outbreaks of SARS-COV-2 resulting in travel restrictions, participation will be sought from researchers from three other European countries
This study aims to investigate the feasibility of using pain neuroscience education for older adults with chronic pain from primary care services. It will have a group of participants receiving pain neuroscience education and exercise and a group receiving usual care.
In this study researchers want to learn about the safety of drug Osocimab at lower-dose and higher-doses in adult participants with kidney disease undergoing regular dialysis (a procedure that uses a machine to get rid of toxins and extra fluids in the blood). Patients with kidney disease undergoing regular dialysis are at high risk for heart and blood vessels diseases. Osocimab is a human monoclonal antibody under development for the prevention of events caused by blood clots like heart attack, stroke and death due to heart or blood vessels diseases. It works by binding to and blocking the activated form of clotting factor XI which increases the formation and stability of clots. Researchers also want to find out how drug Osocimab works in human body and how the body absorbs, distributes and excretes the drug. Participants in this study will receive monthly injection of either Osocimab at a lower-dose or higher-dose or placebo (a placebo looks like a treatment but does not have any medicine in it). Both Osocimab and placebo will be injected into the tissue under the skin of the belly. Observation for each participant will last up to 23 months. Blood samples will be collected from the participants to monitor the safety and measure the blood level of the study drug.
