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.
This study is to demonstrate the safety and efficacy profile, in two different dose regimens of Edoxaban (DU-176b), (an investigational new drug being tested for the prevention of stroke/systemic embolic events (SEE)), in individuals with atrial fibrillation. Patients will be randomized to one of three treatment groups: High Dose Regimen, Low Dose Regimen, & Warfarin. The expected duration of the study is 24 months.
The objective was to investigate the antiviral effect, safety, and pharmacokinetics of BI 201335 (Faldaprevir), given as a soft gelatine capsule, in patients with hepatitis C virus (HCV) genotype 1 infection. Combination therapy of BI 201335 (Faldaprevir) with pegylated interferon α-2a (PegIFN) and ribavirin (RBV), with or without a 3-day lead-in, was assessed in treatment-naïve (TN) and treatment experienced (TE) patients.
The purpose of this study is to determine if lenalidomide (Revlimid®) is safe and effective as a maintenance therapy at improving further the quality of the response you achieved with your last therapy and at prolonging the duration of your response. This study will compare the effects (good and bad) of lenalidomide with the dummy drug.
This project aims to validate a predictive model of diabetic retinopathy progression to clinically significant macular edema (CSME) needing photocoagulation and/or vision loss. The Coimbra Predictive Model (CPM), based on retinal thickness, microaneurysms number, HbA1C and LDL levels, established on a set of 52 diabetic patients, will be tested on a population of 400 patients/eyes to be enrolled into the study. These patients will perform 2 visits at 6-month interval (V0 and V6) to classify each patient into one of the 3 previously established phenotypes. Two years after (V24) patients will be reexamined. The occurrence of end-points, achieved by the patients, are expected to validate our predictive model.
To validate a new methodology, named Retinal Leakage Analysis (RLA), for mapping the human Blood-Retinal Barrier (BRB) function, in the clinical practice.
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's disease.
Investigation of the long-term (12 months) efficacy and safety of milnacipran used in the treatment of fibromyalgia syndrome.
The purpose of this study was to assess the comparative safety and effectiveness of aztreonam for inhalation solution versus tobramycin inhalation solution in adult and pediatric patients with cystic fibrosis (CF) and pulmonary Pseudomonas aeruginosa (PA) infection.
This 3-arm study will assess the efficacy, safety and tolerability of taspoglutide compared to insulin glargine in patients with insulin-naive type 2 diabetes mellitus inadequately controlled with metformin and sulphonylurea combination therapy. Patients will be randomized to receive taspoglutide (10 mg once weekly, or 10mg once weekly for 4 weeks followed by 20mg once weekly) or insulin glargine (starting dose 10 IU/day) in a ratio of 1:1:1 in addition to continued prestudy metformin treatment. The anticipated time on study treatment is 2+ years, and the target sample size if 500+ individuals.
The primary objective was to demonstrate the superiority of insulin glargine over sitagliptin in reducing Glycosylated Hemoglobin A1c (HbA1c) from baseline to the end of the treatment period. Secondary objective was to assess the effect of insulin glargine in comparison with sitagliptin on: - HbA1c level - Fasting Plasma Glucose (FPG) - 7-point plasma glucose (PG) profiles - Percentage of patients with HbA1c <7% and <6.5% Safety objectives consisted of: - Hypoglycemia occurrence - Body weight - Overall safety
