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 study looks at how liraglutide works on participant's body weight. Researchers will look at how liraglutide can help children with obesity to lose weight. They will look at how much weight the children will lose, and if there are any side effects. Participants will either get liraglutide or placebo. Which treatment the participants get is decided by chance. Liraglutide is a new medicine for children, but it can already be prescribed by doctors to adults with overweight or obesity. The participant will get 1 injection every day. In addition to taking the medicine, the participants will have talks with the study staff about healthy food choices, how they can be more physically active and what can be done to help the participants to lose weight. The study will last for about 96 weeks (almost 2 years). The participants will have 18 clinic visits and 10 phone or video calls with the study doctor/staff. Participant will have blood samples taken, have 1 test to check the heart, 1 hand X-ray taken and must fill in a diary between some of the visits.
It is necessary to generate more evidence on the outcome of contemporary protocols for full-arch rehabilitations supported by implants in immediate function in areas with limited quantity and density bone. This research project aims to investigate the outcome of fixed prosthetic restorations supported by implants in immediate function for full-arch rehabilitation through the All-on-4 concept contemporary protocol, specifically: implant survival and success, prosthetic survival, marginal bone level and marginal bone level changes, soft tissue health parameters (Plaque index, Bleeding index, Pocket depth), incidence of biological and mechanical complications. A prospective cohort study design will be used in the investigation. The sample of this study is estimated to consist in 43 patients rehabilitated with full-arch fixed prosthetic rehabilitations supported by implants in immediate function (All-on-4 concept) with 144 dental implants. The cohort will be evaluated between baseline and 3 years of follow-up.
This study is a prospective, observational, non-interventional, multicenter, open-label, single arm study in patients being treated for nAMD with brolucizumab in Portugal.
This is a multiple dose, randomized, placebo-controlled, double-blind study of belcesiran to evaluate the safety, tolerability, PK, and PD in adult patients with PiZZ AATD-associated liver disease (AATLD). The study will be conducted in 3 separate cohorts. A total of up to 16 participants may be enrolled in Cohort 1 and 2. A total number of 30 subjects will be enrolled in cohort 3. The 3 cohorts are differentiated by the duration of the treatment period, the number of doses administered, and the timing of the second liver biopsy.
This study aims to characterize the clinical management and outcomes of participants diagnosed with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC) who are being treated with alectinib in real-world clinical practice.
The primary purpose of this study is to further characterise the hepatotoxicity in participants with advanced or unresectable hepatocellular carcinoma (HCC) treated with lenvatinib, and to further characterise the overall safety profile (serious adverse events [SAEs], grade 3 to 5 adverse events [AEs], dose modifications and discontinuations due to AEs) in participants with advanced or unresectable HCC treated with lenvatinib.
The study aims to evaluate a modified antiplatelet therapy associated with Firehawk low-dose rapamycin DES in acute myocardial infarction patients treated with complete revascularization strategy. The modified antiplatelet therapy consists of a reduced duration of Dual Antiplatelet Therapy post procedure (ie. 1 month duration) followed by P2Y12 inhibitor monotherapy for the next 11 months. It is hypothesized that in the setting of clinically stable, low to moderate complexity acute Myocardial Infarction patients, a modern approach combining a stent with high biocompatibility feature, complete revascularization strategy and modified antiplatelet therapy may be associated with similar outcomes, or even a significant benefit compared with guidelines-recommended 12-month DAPT. This benefit could be driven by a reduced risk in significant bleeding events, while keeping a comparable protection against ischemic risk. Enrolled subjects will be randomized in a 1:1 ratio to either cessation of aspirin at 1 months, either continuation of DAPT. Selection of the P2Y12 inhibitor agent is left to investigator judgment but has to be in line with the current ESC guidelines. Subjects treated with the Firehawk or Firehawk Liberty coronary stent will be included in this study.
Study CC-93538-EE-001 is a Phase 3, multicenter, multinational, randomized, double-blind, placebo-controlled induction and maintenance study to evaluate the efficacy and safety of CC- 93538 in adult and adolescent participants with eosinophilic esophagitis (EoE). The study will incorporate a 24-week Induction Phase followed by a 24-week Maintenance Phase. Participants will be randomized at the beginning of the study into 3 treatment arms: - Placebo for Induction and Maintenance - CC-93538 360 mg Subcutaneous (SC) once weekly for Induction followed by 360 mg SC once every other week for Maintenance - CC-93538 360 mg SC once weekly for Induction and Maintenance
This study will evaluate the efficacy, safety and patient-reported outcomes of trastuzumab emtansine plus atezolizumab compared with trastuzumab emtansine plus placebo in participants with HER2-positive and PD-L1-positive LABC or MBC.Participants must have progressed either during or after prior trastuzumab- (+/- pertuzumab) and taxane-based therapy for LABC/MBC; or during (or within 6 months after completing) trastuzumab- (+/-pertuzumab) and taxane-based therapy in the neoadjuvant and/or adjuvant setting.
The objective of this study is to assess the efficacy and safety of the combination of alpelisib and olaparib compared with single agent cytotoxic chemotherapy in patients with platinum resistant or refractory high-grade serous ovarian cancer, with no germline BRCA mutation detected.
