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 aims to validate the embryo culture medium analysis by nuclear magnetic resonance spectroscopy, as a faster and less-costly alternative to preimplantation genetic test for aneuploidy which could significantly enhance embryo selection and the success rate of assisted reproductive technologies.
The current project aims to develop, implement and assess the effectiveness of an intervention program for perpetrators of intimate partner violence (both volunteers and court-mandated) that incorporates Motivational Interviewing techniques (MIT) as well as cognitive-behavioral and psychoeducational strategies implemented in a community setting. The intervention focuses on ending violence against the intimate partner and promoting the batterer's personal and social skills. The study uses pre- and post-treatment measures, with an experimental group (intervention) and two control groups (a group without intervention and a group without MIT). Data were collected at pre-test, post-test, and follow-up.
Acute pancreatitis represents an acute inflammatory process of the pancreas, which undergoes local and systemic complications, associated with non-negligible morbidity and mortality, and significant economic and quality of life impact. Even after the recovery phase, the development and persistence of sequelae from the inflammatory/necrotic process, including exocrine and endocrine pancreatic insufficiencies, are frequent. Although well documented as consequence of other pancreatic conditions, exocrine pancreatic insufficiency (EPI) after acute pancreatitis is poorly studied and probably underdiagnosed. The prevalence, diagnosis, independent risk factors and therapeutic approaches for EPI after acute pancreatitis need further investigation. Recent evidence suggests the involvement of the pancreas-intestinal axis and immunological dysfunction in several pancreatic pathologies, although their role in the development of EPI after acute pancreatitis is still scarce. Pancreatic enzyme replacement therapy (PERT) is the only treatment currently available in EPI, but the timing for start and duration of this therapy in acute pancreatitis remain to be established. This study have the following objectives: to determine the prevalence, clinical, analytical and nutritional biomarkers and duration of EPI after acute pancreatitis, as well as changes in gut microbiota and immunologic response, and quality of life in EPI and response to PERT after acute pancreatitis; and to determine the prevalence and biomarkers associated with endocrine pancreatic insufficiency following acute pancreatitis and the presence of gut dysbiosis and immunologic changes in acute pancreatitis according to its severity.
A prospective, single arm, non-randomized pivotal study to evaluate the safety and performance of the Xeltis hemodialysis access graft in subjects older than 18 years with end-stage renal disease, who plan to undergo hemodialysis for at least the first 6 months after study access creation.
The WP3 hospitalized cohort in EuCARE is an observational multicentre study including collection of retrospective (historical) and prospective data from hospitalized COVID-19 patients followed at 12 clinics from 11 countries from 4 continents. In a subset of patients, peripheral blood, viral isolates and/or viral sequences are collected for analysis in WP2 with regards to neutralising antibodies, cellular immunity and SARS-CoV-2 diagnostics. Data and results from analysis of biological material will be analysed by biostatistical methods and with artificial intelligence in WP5. This analysis will focus on the impact on clinical outcome of viral variants / viral sequences as well as the vaccines used and the vaccination schedules.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of RO7303509 treatment in participants with systemic sclerosis (SSc) during a multiple-ascending-dose (MAD) portion of the trial. In the MAD phase, increasing doses of study drug will be tested sequentially. For each dose tested, the MAD stage will consist of a treatment period of 12 weeks followed by either a safety follow-up period of 13 weeks or continued treatment in an optional open-label safety extension (OSE) stage of 52 weeks to assess the long-term safety. All patients in the OSE stage will receive RO7303509 and no patient will receive placebo.
Guillain-Barré syndrome (GBS) is a neurological disease characterized by an inflammation of peripheral nerves, which might be responsible for long-term disability. Respiratory muscle weakness is a complication of GBS and might be responsible for respiratory symptoms, inadequate secretion clearance or hypoventilation, with negative impact on daily life. Inspiratory muscle training has been applied in respiratory and neurological diseases and benefits have been observed in symptoms (e.g., dyspnoea), pulmonary function, exercise capacity and quality of life. Nevertheless, results of this intervention in people with GBS are yet unknown. Moreover, rehabilitation is a key player in the recovery of these highly complex patients, however, the interpretation of the magnitude of its effects has been limited by the absence of minimal clinically important differences for most outcome measures. To overcome these drawbacks, methodologically robust trials are needed to build evidence-based rehabilitation to improve clinical care on GBS. The primary aim of this project (RehabGBs) is to develop an inspiratory muscle training protocol - InspireGBs and assess its effects on respiratory muscle strength, peak cough flow, pulmonary function, dyspnoea, fatigue, functional status and quality of life in people with GBS, through a randomised controlled trial. Secondary aims are to: i) establish minimal clinically important differences of Functional Assessment of Chronic Illness Therapy-Fatigue Subscale, Medical Research Council - Manual Muscle Testing, Vital capacity, Maximal Inspiratory Pressure, Peak Cough Flow, Functional Independence Measure and Quality of Life for inpatient rehabilitation programmes of people with GBS ii) Evaluate the prevalence of nocturnal hypoventilation in GBS.
The purpose of this study is to assess the safety and tolerability of zilovertamab vedotin as monotherapy and in combination in participants with select B-cell lymphomas including mantle cell lymphoma (MCL), Richter's transformation lymphoma (RTL), follicular lymphoma (FL), and chronic lymphocytic leukemia (CLL). This study will also evaluate zilovertamab vedotin as monotherapy and in combination with respect to objective response rate. - Cohort A: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 2 prior systemic therapies including a Bruton's tyrosine kinase inhibition/inhibitor (BTKi), and post therapy chimeric antigen receptor T (CAR-T) cell therapy or ineligible for CAR-T cell therapy - Cohort B: Participants with relapsed or refractory RT disease after at least 1 prior systemic therapy - Cohort C: Participants with relapsed or refractory MCL relapsed or refractory disease after at least 1 prior systemic therapy and no prior exposure to a non-covalent BTKi - Cohort D: Participants with relapsed or refractory FL and CLL relapsed or refractory disease after at least 2 prior systemic therapies and have no other available therapy - Cohort E: Participants with relapsed or refractory FL after at least 2 prior systemic therapies and have no other available therapy - Cohort F: Participants with relapsed or refractory CLL after at least 2 prior systemic therapies and have no other available therapy The primary study hypothesis is that zilovertamab vedotin monotherapy has an increased Objective Response Rate (ORR) per Lugano Response Criteria as assessed by blinded independent central review (BICR).
Researchers are looking for a better way to treat children who have chronic kidney disease (CKD), which is long-term kidney disease, and proteinuria, a condition in which a person´s kidneys leak protein into the urine. The kidneys filter waste and fluid from the blood to form urine. In children with CKD, the kidney´s filters do not work as well as they should. This can lead to accumulation of waste and fluid in the body and proteinuria. CKD can lead to other medical problems, such as high blood pressure, also known as hypertension. Vice versa, hypertension and proteinuria can also contribute to worsening of CKD. Therefore, the treatment of CKD aims to control blood pressure and proteinuria. There are treatments available for doctors to prescribe to children with CKD and hypertension and/or proteinuria. These include "angiotensin-converting enzyme inhibitors" (ACEI) and "angiotensin receptor blockers" (ARB). Both ACEI and ARB can help improve kidney function by reducing the activity of the renin-angiotensin-aldosterone system (RAAS). The RAAS is a system that works with the kidneys to control blood pressure and the balance of fluid and electrolytes in the blood. In people with CKD, the RAAS is often too active, which can impair the ability of the kidneys to work properly and cause hypertension and proteinuria. However, ACEI or ARB treatment alone does not work for all patients with CKD as they only target the angiotensin part of the renin-angiotensin-aldosterone system. The study treatment, finerenone, is expected to help control RAAS overactivation together with an ACEI or ARB. So, the researchers in this study want to learn more about whether finerenone given in addition to either an ACEI or ARB can help their kidney function. The main purpose of this study is to learn how safe the treatment is when used of finerenone in addition to an ACEI or ARB in long-term. To see how safe the treatment is, the study team will collect information on medical problems which are also known as "treatment emergent adverse events" (TEAEs). And they will also collect levels of an electrolyte called potassium in the blood by taking blood samples, and measure blood pressure during the study. The secondary purpose of this study is to learn how well long-term use of finerenone can reduce the amount of protein in the participants' urine and benefit kidney function when taken with standard of care. To see how the treatment works, the study team will collect participants' urine samples to assess urinary albumin-to-creatinine ratio (UACR) and urinary protein-to-creatinine ratio (UPCR), which are important assessments for calculating the level of protein in the urine. Researchers will also collect blood samples to analyze serum creatinine and calculate estimated glomerular filtration rate (eGFR). A significant decline in eGFR indicates worsening kidney function. The study will include participants who had previously participated in FIONA study (NCT05196035). The participants will be aged from 1 year up to 18 years. The participants will be in the study for approximately 19 months. They will take study treatment for up to 18 months and will be follow up for 1 month. During this period, at least 12 visits are planned for patients who newly start finerenone, and at least 8 visits for patients who already received finerenone. In the visit, the study team will: - have their blood pressure, heart rate, temperature, height and weight measured - have blood and urine samples taken - have physical examinations - have their heart examined by an electrocardiogram and echocardiography (a sonogram of the heart) - answer questions about their medication and whether they have any adverse events, or have their parents or guardian's answer - answer questions about how they are feeling, or have their parents or guardian's answer - answer question about how they like the study medication, or have their parents or guardian's answer The doctors will keep track of any adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. The doctors will check the participants' health about 30 days after the participants take their last treatment.
The purpose of this study is to evaluate the efficacy of aticaprant compared with placebo as adjunctive therapy to an antidepressant in improving depressive symptoms in adult participants with major depressive disorder (MDD) with moderate-to-severe anhedonia (ANH+) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
