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 evaluated the safety and efficacy of peginterferon alfa-2a monotherapy in participants with Chronic Hepatitis C (CHC) who have End-Stage Renal Disease (ESRD) and were undergoing hemodialysis.
The purpose of this study is to examine the combine effect of the integrated neuromuscular inhibition technique (soft tissue mobilization techniques protocol), in combination with the therapeutic exercise in patients with chronic mechanical neck pain in the sub-acute stage of symptoms, and to determine whether this combination substantially helps the faster and more efficient installation of adaptations of exercising.
The primary objective of this study was to examine the effect of levodopa-carbidopa intestinal gel (LCIG) compared with optimized medical treatment (OMT) on dyskinesia in participants with advanced Parkinson's disease (PD).
This is a phase IV study that will explore the mechanisms of action of a drug (dapagliflozin) that is already commercially available in the country where the study will be conducted (Greece). The drug will be used according to its approved clinical indications (as add-on treatment in patients failed to achieve glycemic targets on metformin monotherapy) and in the approved posology (10 mg/day). Additionally, although there is limited data on the coadministration of dapagliflozin with thiazides, the excellent safety profile of the drug even when it is used in combination with drugs that induce significant volume depletion (such as loop diuretics) suggests that, in properly selected patients, the possibility of important adverse events during the coadministration of dapagliflozin with chlorthalidone is very low. All patients will give written informed consent prior to their enrollment in the study. The study protocol will be approved by the scientific committee of the University Hospital of Ioannina.
GRegistry is a significant collection of data and information on the clinical practice of systemic scleroderma finger ulcers. The GRegistry study is a nationwide (Greece) prospective study recording, which includes consecutive patients with SC-DU diagnosis in clinical management departments of different hospitals, selected in such a way as to reflect a representation of the country. The use of Bosentan in the treatment of patients suffering from systemic sclerosis with digital ulcer disease is supported by data from large, placebo-controlled, randomized studies. The beneficial effect of Bosentan in digital ulcers, a vascular event of systemic sclerosis consistent with its beneficial effect on pulmonary arterial hypertension associated with connective tissue disease and its beneficial effect on vascular remodeling.
The main purpose of this study is to assess the long-term safety and tolerability of galcanezumab administered up to once monthly in participants with episodic or chronic cluster headache who have completed study I5Q-MC-CGAL (NCT02397473) or study I5Q-MC-CGAM (NCT02438826).
The purpose of this study is to assess the effectiveness of a supplement with natural Mastiha on Inflammatory Bowel Diseases (IBD). U.S. Food and Drug Administration has classified Mastiha as GRAS. Previous research demonstrates Mastiha's safety, as well as anti-inflammatory, antimicrobial and antioxidant properties. In addition, the European Medicine Agency has recently recognized Mastiha as a natural medicine and classified it to the category of traditional herbal medicines in diarrhea problems, mild dyspeptic disorders, skin inflammation and healing (EMA/HMPC/46758/2015). Since IBD is a chronic disease characterized by inflammation and oxidative stress and based on previous small-scale studies, the present study aims at demonstrating the effectiveness of this supplement adjunct to the conservative treatment of IBD. To this end, confirmed IBD patients, with distinguished Ulcerative Colitis (UC) and Crohn's Disease (CD) will be enrolled based on certain inclusion and exclusion criteria. The staff of the study will provide detailed information regarding the aims, the methods, anticipated benefits and potential hazards of the study and all patients will receive the Patient Information Leaflet (PIL). Ample time (48 hours) will be provided in order to decide whether they want to participate in the protocol. Each patient agreeing to participate will sign an Informed Consent document and the staff will explain to patients that they are under no obligation to enter the trial and that they can withdraw at any time during the trial, without having to give a reason. A copy of the signed Informed Consent will be given to the participant. 100 IBD patients will be allocated to either Mastiha or placebo group. The Mastiha group will receive natural Mastiha supplement at a dose of 2.8 g daily while placebo group will receive respectively placebo. The intervention will last 3 months for patients in relapse and 6 months for patients in remission. They will receive all the supplements they will consume during the intervention at the start of the trial. Both groups will continue their medical treatment, which must be unaltered throughout the trial. Additionally, all patients will receive standard nutritional advice by dieticians and will be encouraged to report any adverse effects they may experience during the intervention. The trial will be blinded in all implicated persons; neither the staff of the trial nor the patients will be aware of which kind intervention they receive. Patients are assessed after randomisation according to the following tools: - Medical history - Dietary history - Harvey & Bradshaw Activity Index Assessment - Mayo Activity Index assessment - Anthropometric data measurement: body weight (kg), height (cm), Body Mass Index (kg/m2) - Inflammatory Bowel Disease Questionnaire - DNA isolation from whole blood. - Biochemical measurements: Complete blood count, albumin, lipid profile, glucose, electrolytes, liver enzymes, amylase, fibrinogen. - Evaluation of inflammation in serum samples. Circulating serum levels of IL-6, IL-8, IL-17A, IL-17F, IL-18, IL-21, IL-22, TL1A, TGF-β, ICAM-1, MADCAM-1 and E-selectin are measured), in all active CD and UC patients. Inflammatory markers are also estimated in stool samples: calprotectin, lactoferrin and lysozyme, - Oxidative stress assessment in serum/plasma samples. Oxidised LDL, serum oxidisability and F2-isoprostanes are quantified. - Detection of metabolites and complete metabolomic profile in plasma samples. - Stool samples collection for the assessment of gut microbiota in active patients. - Genetic and epigenetic profile Subsequent assessments: There is a biweekly telephone contact with the patients to monitor compliance and side effects. At the end of the intervention each subject undergoes the baseline assessment.
The International study on NoSocomial Pneumonia in Intensive CaRE (PneumoINSPIRE) is a prospective, international, multicentre, observational, cohort study. The study aims to provide up-to-date and generalisable information on current worldwide epidemiology and clinical practice associated with diagnosis and management of nosocomial pneumonia in Intensive Care Unit (ICU) patients. PneumoINSPIRE study is endorsed by the European Society of Intensive Care Medicine (ESICM).
To compare the efficacy and safety of ofatumumab administered subcutaneously (sc) every 4 weeks versus teriflunomide administered orally once daily in patients with relapsing multiple sclerosis
Early stress-dose steroids are of uncertain efficacy in cardiac arrest. The current authors plan to conduct a prospective, randomized, placebo controlled evaluation of stress-dose steroids efficacy with repect to early postresuscitation hemodynamics, heart function, brain perfusion, and inflammatory response in vasopressor-requiring cardiac arrest. Patients will also be followed for organ dysfunction, potential, steroid-associated complications, and functional outcome at hospital discharge.
