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 study is to describe treatment patterns associated with first-line and second line biologic use (vedolizumab or other biologic) and to describe the real-world clinical effectiveness of the use (first-line and second line) vedolizumab versus other biologics at least 6 months post-treatment initiation.
The purpose of this study is to evaluate the effect of TRC101 on the progression of chronic kidney disease (CKD) and to evaluate the safety profile of TRC101 in CKD patients with metabolic acidosis.
The aim of the study is to evaluate results of patients treated with the STABILISE technique for acute/subacute aortic dissection. Results and postoperative events are reported in accordance with the current reporting standards for endovascular aortic repair prepared and revised by the Ad Hoc Committee for Standardized Reporting Practices in Vascular Surgery of The Society for Vascular Surgery/American Association for Vascular Surgery
The purpose of this study is to determine the effectiveness of relatlimab plus nivolumab, alone or in combination with various standard-of-care treatments in participants with gastric cancer (GC) or gastroesophageal junction (GEJ) adenocarcinoma that has come back or spread to other places in the body after prior therapy.
This is a Phase 3, multicenter, randomized, controlled, parallel-group, open-label study to evaluate the effects of plasma exchange using human serum albumin 5% (PE-A 5%) in acute-on-chronic liver failure (ACLF) subjects. The study will involve approximately 40 study centers in the United States, Canada, and Europe with expertise in the management of subjects with ACLF. Subjects with ACLF at a high risk of hospital mortality will be enrolled. The study will consist of a Screening Period during which subjects will be randomized (1:1) to receive either standard medical treatment (SMT) + PE-A 5% (treatment group) or SMT only (control group), followed by a Treatment Period, and a Follow-up Period. The Treatment Period for subjects in the SMT+ PE-A 5% treatment group will be between 7 and 17 days, depending on ACLF evolution. The Treatment Period for subjects in the SMT control group will be a minimum of 7 days for all subjects and up to 17 days depending on the ACLF evolution. Subjects in this group will receive SMT according to the institution's standards. The Follow-up Period for subjects in both groups will be 90 days.
PRIME goal is to early detect and treat acute exacerbations of chronic obstructive pulmonary disease (AECOPD). This is important since COPD accelerates aging and represents major burden worldwide and in Portugal, mainly due to its frequent AECOPD. Pulmonary rehabilitation (PR) is an effective strategy of its management but it is scarce. When AECOPD are early detected and treated, it optimizes patients' outcomes and reduces the burden of COPD, especially if PR is used. However, up to date, there is no model to predict AECOPD for clinical practice. The lung microbiota shows promise to overcome this barrier and inform on COPD trajectory and will be investigated. In addition, despite of most AECOPD being managed in the community, PR is mainly available in hospitals and less than 1% of patients are having access. Thus, community-based PR will be implemented and a clinical decision tool developed for prioritizing who will most benefit from PR, enhancing evidence-based access to PR.
12-30% of children present handwriting difficulties, which has negative repercussions on their school career. For this reason, it is fundamental to bet on their prevention. The aim of present study is to examine the effects of a graphomotor intervention program on quality and speed of handwriting in second-grade children. This experimental study is a randomized controlled trial. The program will run for 8 weeks (2 sessions/week of 30 minutes), followed by 6 months of follow-up without intervention. Participants will be assessed 1) at baseline, 2) at the end of the program, and 3) after the follow-up. Participants will be randomly allocated to two groups: experimental group (graphomotor intervention program) and control group.
12-30% of children present handwriting difficulties, which has negative repercussions on their school career. For this reason, it is fundamental to bet on their prevention. The aim of present study is to examine the effects of a graphomotor intervention program on graphomotor competences in children in the last year of preschool education. This experimental study is a randomized controlled trial. The program will run for 8 weeks (2 sessions/week of 30 minutes), followed by 6 months of follow-up without intervention. Participants will be assessed 1) at baseline, 2) at the end of the program, and 3) after the follow-up. Participants will be randomly allocated to two groups: experimental group (graphomotor intervention program) and control group.
Single-arm, phase II clinical trial of patients with Extranodal Marginal Zone Lymphoma (EMZL). It is planned to recruit 130 patients. Additional patients with Splenic Marginal Zone Lymphoma (SMZL), up to 30, and Nodal Marginal Zone Lymphoma (NMZL), up to 15, will be included in the trial in order to preliminary explore the clinical activity and safety of the combination treatment proposed. The study primary endpoints will be analysed on the EMZL population. Outcome of patients with SMZL and NMZL will be analysed and reported separately
