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 the study is to compare the efficacy and safety of Luspatercept vs epoetin alfa in the treatment of anemia in adults due to IPSS-R very low, low, intermediate-risk MDS in ESA-naïve participants who are non-transfusion dependent (NTD).
The goal of this multicentre, observational study on mpox in infants, children and adolescents is to increase knowledge about mpox infection and its associated disease in infants, children and adolescents. This will be done through the development of a harmonized system that will allow standard collection of information on demographics, clinical symptoms, clinical course, treatments and outcomes. The study will be carried out in three potential phases: Phase 1 entails the rapid development of an online paediatric registry collecting anonymised data from routine care on infants, children and adolescents with laboratory-confirmed mpox virus infection. If warranted, the study will proceed to Phase 2, an enhanced observational study of children and adolescents with confirmed mpox virus infection, if more detailed prospective data collection would aid the public health response. There is also the potential to initiate Phase 3, comprising of nested sub-studies to investigate specific research questions in this population.
The purpose of this study is to assess the safety and efficacy of two doses of Deucravacitinib in adult participants with Active Sjögren's Syndrome.
Non-alcoholic fatty liver disease (NAFLD) is associated with increased cardiovascular risk. The aim of this study is to investigate the effects of coenzyme Q10 (CoQ10) on endothelial, vascular and myocardial function in patients with NAFLD
The primary objective of the study is to determine the effect of seralutinib on improving exercise capacity in subjects with WHO Group 1 PAH who are FC II or III. The secondary objective for this trial is to determine time to clinical worsening.
The purpose of this study is to learn if V940 which is an individualized neoantigen therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab (MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma. Researchers want to know if V940 with pembrolizumab is better than receiving pembrolizumab alone at preventing the cancer from returning.
Crohn's disease (CD) is an incurable chronic inflammatory disorder of the gastrointestinal tract. This study will assess how safe and effective upadacitinib is in treating moderately to severely active CD in real world. Speed of onset and durability of effectiveness will be assessed. Upadacitinib is a drug approved for the treatment of CD. All study participants will receive upadacitinib as prescribed by their study doctor in accordance with approved local label. Approximately 1200 participants will be enrolled in approximately 230 sites across the world. Participants will receive upadacitinib as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 3 years. There is expected to be no additional burden for participants in this trial. Study visits may be conducted on-site or virtually as per standard of care.
This study aims to assess the efficacy and safety of bulevirtide (BLV) in chronic hepatitis D patients treated in Greek liver centers.
There is high possibility of relapse of the lower anterior teeth after orthodontic treatment. Relapse is related with the initial orthodontic anomaly, pathology of surrounding tissues, patient's age and sex and compliance and the retention protocol applied. The options for the later are various. Permanent fixed retainers are considered of the most common ones and vastly vary based of composition. There are fixed retainers distinguished for their composition (SS, β-NiTi, fiber-reinforced composite retainers) or for their shape and dimensions (round or rectangular shape and single-strand or multi-strand respectively), and/or for the teeth they are placed on (canine and canine or canine to canine). Fixed retainers may require patient's cooperation , nevertheless debond failure rate varies between 0.1-53%. The aim of this prospective randomized clinical study is to compare failure incidents and retention effect on lower anterior teeth after orthodontic finish between three different types of fixed retainers. There will be 3 arms studied in this research: a) single strand 0.016x0.022'' β-Ti canine to canine, b) 0.028'' SS canine to canine and c) 0.027'' multi-strand twistflex canine to canine. Variables such as repeatability of failures, and undesired tooth movements will be measured. Measurements will be repeated every 3 months after patient's recruitment in this study, for one year period (12 months in total). Intraoral scans will be collected during baseline (fixed retainer insertion) and after 12 months.
The PRECISION is a proof-of-concept, phase II randomized clinical trial aiming to evaluate the efficacy and safety of anakinra in patients with Post-Acute COVID Syndrome (PACS) of the pro-inflammatory respiratory phenotype. Improvement is measured by a composite endpoint, namely, the "Score of PACS progression reversal"
