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 primary objectives of this randomized clinical trial are a) to implement and test the impact of a 1-year lifestyle obesity treatment program based on Self-Determination Theory on 3-year change in physical activity and motivation for exercise/physical activity, body weight and fat, and selected eating variables, b) to identify behavioral and psychosocial theory-based moderators or mediators of primary outcomes, especially physical activity and body weight.
The study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone with Anti-VEGF treatment vs. Anti-VEGF alone (with sham dexamethasone injection) in patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration.
The study will examine the efficacy,safety and tolerability of combination therapy of tamsulosin and solifenacin compared to placebo and monotherapy of tamsulosin and solifenacin in the treatment of males with LUTS associated with BPH.
The purpose of this study is to further evaluate the safety of infliximab, ustekinumab, and guselkumab in patients with plaque and other forms of psoriasis. The study also includes patients receiving other therapies, such as non-biologic and other biologic agents. The registry also evaluates patient and disease characteristics, including patient-reported assessment of psoriatic arthritis (PsA); and clinical and quality of life outcomes.
This patient follow-up programme was designed to describe the extent of Symbicort use in patients prescribed Symbicort as maintenance and reliever therapy in routine clinical practice in comparison with the already documented use of Symbicort as maintenance and reliever therapy in clinical therapies
This extension study will investigate the long-term safety and tolerability of multiple intravitreal injections of ranibizumab administered to patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration who have been previously treated in either of the two ongoing ranibizumab studies CRFB002A2302 (EXCITE) or CRFB002A2303 (SUSTAIN
This trial is conducted in Africa, Asia, Europe, North and South America and Oceania. The aim of the trial is to evaluate the effect of somatropin (human growth hormone) on survival (primary end-point; "time to death" and health related quality of life in adult patients on chronic haemodialysis.
The primary objective of this study is to compare two methods of post-delivery stabilization and subsequent early respiratory care for reducing the need for MV and related secondary complications, such as BPD, in premature babies at high risk of RDS: 1. Early stabilization on nCPAP 2. Intubation, prophylactic surfactant (Curosurf®) administration shortly after delivery, and rapid extubation to nCPAP. The data obtained from this comparison will be applied to test the hypothesis that preterm neonates at risk of RDS who are treated with prophylactic surfactant + nCPAP show less need for MV when compared to infants who receive nCPAP alone.
The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME™ EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.
The primary objective of this study is to assess the long-term safety and impact on disease activity and progression of Tysabri in participants with relapsing remitting multiple sclerosis (RRMS) in a clinical practice setting.
