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.
The purpose of this study is to determine whether 7-valent pneumococcal conjugate vaccine safely induces immune responses and immunological memory in children with idiopathic nephrotic syndrome in remission.
Calprotectin is a cytosolic component of neutrophils .Fecal calprotectin(FC) is a useful marker for exacerbation of inflammatory bowel disease in children .FC may be a useful marker for necrotizing enterocolitis (NEC). NEC is one of the most common ,deadliest and enigmatic intestinal problems encountered mostly in premature infants. The precise pathophysiology of NEC is unclear ,but major factors thought to play an important role include an immature intestine ,an inflammatory response to intestinal microbes,enteral feedings and intestinal ischemia-reperfusion injury.Diagnosis of NEC is not easy clinically and up to now there is not a simple laboratory test to differentiate NEC at an early stage from other conditions in the neonate. Arginine is the substrate for NO production in the gut and its deficiency may cause vasoconstriction and gut injury and thus predispose to NEC. In previous studies arginine supplementation was found to reduce the incidence of NEC in premature infants but more studies are needed for the use of arginine supplementation for the prevention of NEC. The investigators aim is to measure the fecal calprotectin in very low birth weight (VLBW) infants during the first month of life as an inflammatory marker of the bowel and evaluate whether premature infants receiving arginine supplements had lower calprotectin values compared to the premature infants that did not . The investigators hypothesize that arginine supplementation in preterm infants reduces the inflammation of the gut which will be shown by the lower fecal calprotectin values of the premature infants receiving arginine supplementation.
The purpose of this study is to compare whether a 3-month treatment is at least not inferior to a 6-month treatment (FOLFOX-4 6 vs. 12 cycles or XELOX 4 cycles vs. 8 cycles) in terms of RFS in patients with high risk stage II or stage III radically resected colon cancer.
To examine the safety and toxicity of concurrent radiotherapy with cisplatin with the further addition of cetuximab experimental treatment
The purpose of this study is to evaluate the effect of patient outreach program on the proportion of time patients with MTC experience moderate or severe AEs during first 12 months of treatment with vandetanib
This is a prospective, randomized, multi center study. Approximately 2700 patients will be entered in the study and will be randomized on a 2:1 basis. Patients who meet the eligibility criteria will be randomized to the everolimus eluting XIENCE-V®, XIENCE-Prime® or PROMUS® stent versus the Biolimus A9 eluting NOBORI® stent. Patients will be followed for 5 years.
Study phase: phase III Study objective: - Comparison of Bortezomib, Melphalan, Prednisone (VMP) with High Dose Melphalan followed autologous stem cell transplantation (ASCT) - Comparison of Bortezomib, Lenalidomide, Dexamethasone(VRD) as consolidation versus no consolidation - Comparison of single versus tandem high dose Melphalan with ASCT Patient population: Patients with symptomatic multiple myeloma,previously untreated, ISS stages 1-3, age 18-65 years inclusive Study design: Prospective, multicenter, intergroup, randomized Duration of treatment: Expected duration of induction, stem cell collection and intensification is 6 - 9 months. Consolidation with VRD will last 2 months Maintenance therapy with Lenalidomide will be given until relapse. All patients will be followed until 10 years after registration.
This study is carried out to see how Caucasian patients with lung cancer which has EGFR mutation will respond to gefitinib (IRESSA™) as a first line treatment. Safety data will also be collected and analysed to confirm that treatment with gefitinib is safe and well tolerated.
The aim is to explore whether the incidence of progesterone rise in the late follicular phase differs between GnRH-agonist and GnRH-antagonist protocols for IVF and whether this has an impact on the probability of pregnancy achievement.
Rationale: Gathering medical information and tumor samples from patients with male breast cancer may help doctors learn more about the disease. Purpose retrospective part: to perform a large international retrospective analysis of clinical and biological data of male BC patients treated in the participating centers from 1990 to 2010. Purpose prospective part: to create a registry of men with breast cancer for a period of 30 months (starting early 2014).
