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 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.
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
This open-label, single arm study will investigate the safety, tolerability and efficacy of tocilizumab monotherapy, or combination therapy with non-biologic disease modifying antirheumatic drugs (DMARDs), in patients with severe active RA. Patients will receive tocilizumab 8mg/kg iv as a 60 minute infusion every 4 weeks for a total of 6 infusions. The anticipated time on study treatment is 3-12 months, and the target sample size is >500 individuals.
The purpose of this study is to investigate the safety and efficacy of neramexane mesylate in the treatment of subjective tinnitus in comparison to placebo.
This study evaluates the effects of 12-week treatment with two doses of tiotropium bromide (2.5 mcg q.d. and 5 mcg q.d.) compared to placebo administered via the Respimat device on lung function in patients with Cystic Fibrosis. The selection of the optimal dose will be based on bronchodilator efficacy, safety evaluations and pharmacokinetic evaluations
