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 main purpose of this study is to compare the Human Acellular Vessel (HAV) with ePTFE grafts when used for hemodialysis access.
The purpose of this study is to assess long-term safety data of GED-0301 for a period of up to 208 weeks in adult subjects (i.e., ≥ 18 years of age) who participated in the core Phase 3 GED-0301-CD-002 and GED-0301-CD-003 studies and adolescent subjects (i.e., 12 to 17 years of age) who participated in the core Phase 3 GED-0301-CD-003 study. Although all subjects will receive active treatment, this study is double-blinded for the entire 208 weeks for the purpose of preserving the blind of the subject's treatment allocation in the initial, core Phase 3 GED-0301 study. The GED-0301-CD-003 trial was not initiated; see detailed description.
Evaluation of a new ELISA based interferon-gamma release assay (QuantiFERON TB plus In-tube test) in immunocompromized patients
The primary aim of this study is to evaluate if VTIQ in addition to BI-RADS® categorization can improve the diagnostic accuracy with respect to detection of malignancies, in particular for BI-RADS® categories 3 and 4a. The idea of the study is to restage all patients in categories 3 and 4a according to a predefined VTIQ cut-off value of ≥ 3.5 m/s (37 kPa).
Type 2 diabetes is a chronic disease that affects approximately 13% of Portuguese population and is associated with a high cardiovascular mortality by coronary artery disease and cerebrovascular disease and with a serious decline on well-being. Lifestyle changes are widely recommended to the control of type 2 diabetes and its complications. This study aims to analyse the effects of different community-based lifestyle programs (exercise or exercise plus dietary intervention) on health and well-being in patients with type 2 diabetes.
The purpose of this study was to assess efficacy, including inhibition of radiographic progression, and safety with upadacitinib versus placebo and versus an active comparator, adalimumab, in adults with with moderately to severely active rheumatoid arthritis (RA) who are on a stable background of methotrexate (MTX and who have an inadequate response to MTX.
In this study, participants with multiple types of advanced (unresectable and/or metastatic) solid tumors who have progressed on standard of care therapy will be treated with pembrolizumab (MK-3475).
The purpose of this study is to assess whether copanlisib in combination with standard immunochemotherapy (rituximab in combination with bendamustine [R-B] and rituximab in combination with a 4 drug combination of cyclophosphamide, doxorubicin, vincristine and prednisone/prednisolone [R-CHOP]) is effective and safe, compared with placebo in combination with standard immunochemotherapy (R-B or R-CHOP) in patients with relapsed iNHL who have received at least one, but at most three, lines of treatment, including rituximab-based immunochemotherapy and alkylating agents.
The main purpose of this study is to describe the safety and tolerability of 80 weeks of subcutaneous (SC) evolocumab when added to standard of care in children 10 to 17 years of age with familial hypercholesterolemia.
NOAH is an investigator-initiated, prospective, parallel-group, double-blind, randomised, multi-centre trial. The objective of the trial is to demonstrate that oral anticoagulation using the NOAC edoxaban is superior to current therapy to pre-vent stroke, systemic embolism, or cardiovascular death in patients with AHRE and at least two stroke risk factors but without AF. The trial will be conducted in several European countries.
