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 international, multicenter, randomized, double-blinded, placebo-controlled study is designed to compare the efficacy and safety of taselisib + fulvestrant with that of placebo + fulvestrant in postmenopausal women with estrogen receptor (ER)-positive, human epidermal growth factor receptor-2 (HER2)-negative, oncogene that encodes for phosphatidylinositol-4,5-bisphosphate 3-kinase (PIK3CA)-mutant, unresectable, locally advanced or metastatic breast cancer after recurrence or progression during or after an aromatase inhibitor (AI) therapy. There will be a 2:1 randomization to the taselisib arm versus the placebo arm. Enrollment will be enriched for participants with PIK3CA mutant tumors via central testing. The anticipated duration of the study is approximately 3.5 years.
The study is designed to compare the effects of BI 409306 compared to placebo in patients with cognitive impairment due to Alzheimer's Disease
The main purpose of this study is to show the non-inferiority of the incidental irradiation, as compared to intentional irradiation of the axillary nodes, in terms of 5-years disease-free survival (DFS) of early stage breast cancer patients with limited affectation of sentinel node assessed by OSNA (250 to 15,000 copies/uL), treated with breast-conservative surgery without axillary lymphadenectomy.
The aim of this project is to evaluate the needs and provision of care for patients in the late stages of Parkinsonism and their carers in several European countries, to compare the effectiveness of different health and social care systems, and to lay the foundation for improved outcomes in this population. The investigators will undertake an in-depth assessment of patients and their care arrangements in a population recruited through networks in six European countries. The systems and procedures that are used in the provision of care will be reviewed through a systematic literature review, interviews and assessments of patients, carers and health care providers, and through a trial comparing assessment by a specialist with management suggestions, guidance and access to telephone advice to that of usual care. Through interviews, questionnaire assessment and review of current health-care and social care arrangement, the investigators will assess the needs, provision of care and use of health-care resources, and their impact on patient and carer outcomes in different countries. National and regional databases will also be interrogated to identify current practice and use of healthcare resources and drug usage. A systematic literature review of the evidence for effective management strategies, analysis of the study data, and evaluation of change in outcomes following specialist review will provide the basis for recommendations in the management of late stage Parkinsonism. The investigators will also evaluate potentially useful outcome measures for use in this patient group. In addition to charting the needs and current care provision for late stage Parkinsonism in different European countries, its cost and effectiveness, and an analysis of health-care and social care predictors of improved outcome, the project will produce a platform for the assessment of patients with late stage Parkinsonism, their current treatment and care provision, as well as guidelines on the management of this late disease phase.
The great diversity of regimens and treatment lines, the different efficacy of these, mostly due to the increase in bacterial antibiotic resistance and regional differences, requires a continuous critical analysis of clinical practice, evaluating systematically the efficacy and safety of the different regimens and the cost-effectiveness of the different diagnostic-therapeutic strategies. This will help in the design of an efficient and optimized treatment that will reduce number of re-treatments, diagnostic tests and the appearance of associated pathologies such as peptic ulcers, gastrointestinal bleeding and, probably, gastric cancers. Therefore, the evaluation of real clinical practice using non-interventionist registries will help to improve the design and organization of European Consensus on the management of H. pylori infection, which is the best way to establish healthcare efficiency. Primary aim To obtain a database registering systematically over a year a large and representative sample of routine clinical practice of European gastroenterologists in order to produce descriptive studies of the management of H. pylori infection. Secondary aims 1. To evaluate H. pylori infection consensus and clinical guidelines implementation in different countries. 2. To perform studies focused on epidemiology, efficacy and safety of the commonly used treatments to eradicate H. pylori. 3. To evaluate accessibility to healthcare technologies and drugs used in the management of H. pylori infection. 4. To allow the development of partial and specific analysis by the participating researchers after approval by the Registry's Scientific Committee Methodology Non-interventionist prospective multicentre international registry promoted by the European Helicobacter Study Group. A renowned gastroenterologist from each country was selected as Local Coordinator (30 countries). They will in turn select up to ten gastroenterologists per country that will register the routine clinical practice consultations they receive over 10 years in an electronic Case Report Form (e-CRF). Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation and outcome data. The database will allow researchers to perform specific subanalysis after approval by the Scientific Committee of the study.
The purpose of this study is to assess whether the Closed Loop Stimulation (CLS) in addition to the DDD pacing is effective in reducing syncopal recurrences. The study hypothesis is that DDD pacing with CLS stimulation is able to prevent syncopal recurrences completely or partially by transforming syncope in pre-syncope.
Cardiac resynchronization therapy (CRT) has been shown to reduce heart failure (HF), hospitalizations and death in patients with left ventricular ejection fraction (LVEF) <35% and wide QRS. CRT provides electromechanical resynchronization and improves LV systolic function. The induced LV reverse remodeling or near normalization in LVEF to ≥45% is associated with a significant reduction in the risk of subsequent life-threatening ventricular tachyarrhythmias (VTA). And at the time of replacement, the need for defibrillator back-up after an event-free first CRT-D service-life for patients with improved LVEF is a controversy question. 80% of Implantable Cardioverter Defibrillator (ICD) patients implanted for primary prevention do not experience VTA during the life-time of their first device. So, regarding patients implanted with a CRT-D for primary prevention at the time of first implantation, the question is will they experience VTA after their device replacement by another CRT-D.
This is a single-arm, multi-center, open-label extension study designed to provide continued pertuzumab therapy to patients receiving pertuzumab as an investigational medicinal product (IMP) in a Roche-sponsored global study and who continue to receive pertuzumab at the end of the Parent study, as well as to collect long-term safety and efficacy data of pertuzumab therapy. Patients with solid tumors who have not experienced progressive disease in the Parent study and, in the investigator's opinion, may potentially benefit from continued pertuzumab treatment, will continue to receive pertuzumab until disease progression, unacceptable toxicity, investigator/patient decision, patient non-compliance, patient death, patient request to withdraw, or study termination by the Sponsor, whichever occurs first.
The purpose of this study is to look at the long term safety profile of Orfadin treatment in patients suffering from hereditary tyrosinemia type 1 (HT-1). Patients included in the study will use Orfadin according to normal clinical practice.
The primary objective of the RIC-STEMI trial is to assess whether remote ischaemic conditioning (RIC) as an adjunctive therapy during primary percutaneous coronary intervention (PCI) in patients presenting with ST-elevation myocardial infarction (STEMI) can improve clinical outcomes as assessed by death from cardiac-cause or hospitalization for heart failure (HF) for a minimum follow-up period of 12 months.
