There are about 4372 clinical studies being (or have been) conducted in Greece. 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 deals with coverage of multiple denuded roots. The current standard treatment requires surgical correction and uses soft tissue taken from the roof of the mouth to enhance results. The hypothesis of this trial is that a synthetic collagen matrix (called Mucograft) can be used to replace soft tissue taken from the subject. If the collagen matrix will prove to be equally as effective as the patient own tissue, it will be possible to avoid a more extensive surgery and decrease pain and discomfort.
This is a prospective, multicenter, feasibility study on the safety and efficacy of renal denervation in patients with resistant hypertension.
This study aims to demonstrate a clinically significant improvement in Forced Expiratory Volume in one second (FEV1) in moderate to severe allergic asthmatics inadequately controlled by Inhaled Corticosteroid (ICS) therapy. Patients will be treated with QAW039, an active comparator, or placebo. This will be a randomized, placebo-controlled, dose-ranging, multi-centre trial.
The purpose of this study is: - To compare blood sugar control on LY2605541 with insulin glargine after 52 weeks of treatment. - To compare the rate of night time low blood sugar episodes on LY2605541 with insulin glargine during 52 weeks of treatment. - To compare the number of participants on LY2605541 reaching blood sugar targets without low blood sugar episodes at night to those taking insulin glargine after 52 weeks of treatment. - To compare the rate of low blood sugar episodes on LY2605541 with insulin glargine after 52 weeks of treatment
The purpose of this study is to compare the safety and efficacy of masitinib 6 mg/kg/day versus placebo in the treatment of patients with primary progressive multiple sclerosis or relapse-free secondary progressive multiple sclerosis.
The purpose of the study was to assess the efficacy of the Allegretto Wave excimer laser and the wavefront optimized ablation profile in correcting primarily non-anterior astigmatism faults, following laser in-situ keratomileusis (LASIK) and photorefractive keratectomy (PRK).
The purpose of this study is to provide anti-HCV drugs to +/- 200 subjects treated in prior BMS studies with placebo + Peginterferon Alfa-2a and Ribavirin and determine if the addition of these drugs can result in higher cure rates in patients who previously failed therapy. Approximately 100 genotype 1b subjects rolling over from BMS study AI447-028 who received placebo will be treated with active drugs in this study.
THE STUDY WILL BE A TWO-PART RESEARCH PART A and PART A extended: 1. To implement a "common" MRI acquisition protocol in multiple centers across Europe (Pharma-COG partners). 2. Apply the common MRI protocol on phantoms and human subjects to characterize, compare and minimize test-retest variability across the MR sites of WP5 for all the quantitative metrics that will be later assessed on patients. PART B: By collecting clinical, biochemical, neuroimaging, neuropsychological and neurophysiological data in Mild Cognitive Impairment patient, we aim to: 1. To develop a biomarker MATRIX (made of a combination of biological secondary endpoints) which is more sensitive than the changes observed in the loss of hippocampal volume (primary endpoint) and correlate with the neuropsychological progression and conversion (clinical secondary endpoints). 2. To develop a biomarker MATRIX (made of a combination of biological secondary endpoints) at baseline which is more predictive of the loss of hippocampal volume (primary endpoint) and neuropsychological progression (clinical secondary endpoint) in MCI patients. 3. To harmonize the biomarker MATRIX collection and qualify multiple centres across Europe
Objective: To assess the accuracy of transcutaneous bilirubin (TcB) measurements in neonates, in relation to gestational age (GA), time (postnatal hour) and site (forehead, sternum, knee) of measurements. Hypothesis: Using (or combining) different sites for TcB determination might improve the accuracy of TcB in relation to the time of measurement and the GA of the neonate. Methods: The study will include neonates >32 weeks' gestation cared for in the well-baby nursery and NICU of the University Hospital of Patras, from September to December 2011. Data such as sex, gestational age, gestation and perinatal information, mother's and infant's ABO group and Rh, G6PD deficiency, Coombs test, type of delivery and complications, birthweight, postnatal medications and interventions, type and volume of feeding, and extension of jaundice, will be collected. TcB measurements will be performed using the BiliCheck bilirubinometer (according to the standard protocol) at 3 different sites: forehead, sternum and knee. Total serum bilirubin (TSB) values will be obtained using the heel stick technique, and measurements will be performed by a direct spectrophotometric device (Unistat bilirubinometer, Richert, Depew, NY). The accuracy of the device has been validated previously. TSB measurements will be performed within 5 minutes of the TcB measurements. At each occasion TcB measurements (3), the corresponding TSB value, the time of measurement (postnatal hours), and the actual weight will be noted. Statistics: The agreement between TcB and TSB values will be assessed using the Bland-Altman % method. The independent and joint effects of GA and time of measurement on bias will be evaluated by multivariate regression analysis.
The main purpose of this study is to compare the effectiveness and safety of LY2963016 versus Lantus in controlling blood sugar levels in combination with two or more oral diabetes medications.
