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 identify Diabetic Macular Edema (DME) characteristics in eyes that show different response to treatment with anti-VEGF (vascular endothelial growth factor) injections of Lucentis.
The consequences of alcohol dependence are severe and may range from physical diseases to neuropsychological deficits in several cognitive domains. Alcohol abuse has also been related to brain dysfunction specifically in the prefrontal cortex. To assess these deficits and the application of a novel approach of cognitive stimulation to alcoholics, we have carried out a neuropsychological intervention program with mobile health technology. Patients diagnosed with alcohol dependence syndrome were submitted to cognitive stimulation during four weeks in a three-day/week basis.
The study is a randomized, double blind, placebo controlled, Phase 3 clinical trial with the primary objective of demonstrating the superiority of palbociclib in combination with fulvestrant (Faslodex®) over fulvestrant alone in prolonging PFS in women with HR+, HER2 negative metastatic breast cancer whose disease has progressed after prior endocrine therapy. The safety between the two treatment arms will also be compared. During study treatment, pre- and perimenopausal women must be receiving therapy with the LHRH agonist goserelin (Zoladex® or generic).
This study is a prospective, randomized, multicentre, open label study that intents to compare the efficacy and safety of ranibizumab 0.5 mg Intravitreal (ITV) injections plus Panretinal Photocoagulation versus Panretinal Photocoagulation alone in the regression of the neovascularization area in patients with High Risk Proliferative Diabetic Retinopathy over a 12-month treatment period. One of the major complications of the diabetes mellitus is Diabetic Retinopathy (DR), one of the leading causes of visual impairment in working age in industrialized countries. Longer diabetes duration and poor glycaemic and blood pressure control are strongly associated with Diabetic Retinopathy. The overall prevalence of any form of Diabetic Retinopathy is 34.4% and 6.96% corresponds to Proliferative Diabetic Retinopathy (PDR). Therefore, approximately 93 million people have Diabetic Retinopathy and 17 million of them have Proliferative Diabetic Retinopathy. It has been shown that treatment with repeated injections of ranibizumab can improve visual acuity in patients with PDR. Further, , the standard PRP treatment of PDR remains unsatisfactory. The knowledge of the mechanisms of this retinal complication is incomplete and, therefore, efforts should be done to understand and characterize patients' eyes response to combined treatments. Therefore, the purpose of this study is to compare the standard treatment for PDR (i.e. Panretinal Photocoagulation) with Panretinal Photocoagulation treatment combined with ITV injections of ranibizumab since it is expected that anti-vascular endothelial growth factor (VEGF) treatment with ITV injections will increase the rate of success of Panretinal Photocoagulation in regression of neovascularization with improved final visual acuity.
To determine the efficacy and Security of Thymoglobuline in cadaveric donor Efficacy: To demonstrate that in cadaveric donor, Thymoglobuline diminished graft alloreactivity by decreasing expression of inflammatory markers in graft biopsies Security:To demonstrate that the administration of Thymoglobulin does not have side effects in renal recipients.
This double-blind randomized, parallel group study will evaluate the efficacy and safety of lenalidomide (Revlimid, CC-5013) in combination with rituximab (MabThera/Rituxan) in patients with relapsed or refractory follicular lymphoma or marginal zone lymphoma. Patients will be randomized to receive either lenalidomide or placebo for twelve 28-day cycles in combination with rituximab. Anticipated time on study treatment is 1 year.
Retrospective, non-interventional, observational multi-center field study. Patients diagnosed with wet Age-related macular degeneration (wAMD) and having started treatment with ranibizumab between January 1, 2009 and December 31, 2009 must be consecutively screened and, if eligible, enrolled. Patients will be followed up at maximum until December 31, 2011. Switch to any other Anti vascular endothelial growth factor (anti VEGF) treatment will be documented. For each patient, demographics, medical history, administered treatments, results of ocular and visual assessments and other tests (where available) will be documented.
The primary objective of the study is to estimate the annualized relapse rate (ARR) in participants with Relapsing Remitting Multiple Sclerosis (RRMS) who are treated with dimethyl fumarate (DMF) over a 12-month period. The secondary objectives of this study in this population are to assess the impact of DMF over a 12-month period on participants -reported health-related quality of life (HRQoL) outcomes, additional clinical effectiveness outcomes, and health economics-related outcomes, and to characterize participants-reported adherence to DMF.
This trial is conducted in Africa, Asia, Europe and South America. The aim of the trial is to evaluate efficacy and safety of semaglutide once-weekly versus sitagliptin once-daily as add-on to metformin and/or TZD (thiazolidinedione) in subjects with type 2 diabetes.
The objective of this study is to describe the effect of optimized retreatment with bortezomib in combination with dexamethasone followed by prolonged therapy with bortezomib, versus standard retreatment with bortezomib in combination with dexamethasone on progression free survival (PFS).
