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.
Oocyte quality is a basic parameter that affects embryo quality and therefore it influences the outcome of assisted reproduction. It has been suggested that oocyte quality is improved by the intake of vitamins and antioxidants. Ova-Max is a dietary supplement that consists of vitamins, minerals and antioxidants which improve women's oocytes by preventing oxidative stress. Specifically, Ovamax includes Chasteberry, Melatonin, Myo-Inositol, Folic Acid, Co-Enzyme Q10, Vitamin E, L-Arginine, Grape seed extract and Alpha-lipoic Acid. The purpose of this study is to evaluate the influence of Ova-max intake on oocyte quality in women undergoing In Vitro Fertilization. According to the research hypothesis the administration of Ova-Max for three months increases oocyte quality in women undergoing intracellular sperm injection after ovarian stimulation and oocyte retrieval.
Perioperative hypotension is a risk factor for perioperative complications. Advances in machine learning and artificial intelligence have produced an algorithm that predicts the occurrence of hypotension episodes by analyzing an arterial pressure waveform. This technology has not been validated in thoracic surgical patients undergoing lung resections with the use of one-lung ventilation (OLV). We planned an observational, prospective multi-centre cohort validation study of the Hypotension Prediction Index (HPI) in patients undergoing lung resection procedures with the use of one-lung ventilation and a lung-protective strategy.
The study is being done to see if ziltivekimab can be used to treat participants living with heart failure and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (inactive substance that looks like the study medicine but does not contain any medicine). The treatment participants get is decided by chance. Participant's chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study is expected to last for up to 1 year and 4 months.
Despite Transcatheter aortic valve implantation (TAVI) evolution regarding techniques, equipment and experience, the need for permanent pacemaker implantation (PPI) post-TAVI remains an important drawback. The electrophysiology testing to stratify the risk or necessity of PPI post-TAVI is endorsed by the up-to-date guidelines and consensus documents and it is a valuable cut-off based method. Part of the answer is maybe hidden in the easy and applicable testing of the atrioventricular conduction system through rapid atrial pacing (RAP) with a common temporary pacemaker lead. This trial is designed to investigate the role and value of RAP after TAVI as a predictor of the necessity of new PPI.
This is a multicenter, single arm, open-label, Phase 2 study in mutiple myeloma with newly diagnosed and treatment-naïve participants for whom high-dose therapy and autologous stem cell transplantation is part of the intended treatment plan. The study is evaluating a technique called Mass Spectrometry Minimal Residual Disease (MS-MRD) using blood samples and compares it with the minimal residual disease (MRD) technique using bone marrow samples.
This is a multicenter, observational, prospective, national study which includes patients with chronic kidney disease (CKD) under dialysis or not, or with heart failure (HF), treated with sodium zirconium cyclosilicate (SZC) as per Summary of Product Characteristics (SmPC), aiming to collect information on patient characteristics, routine clinical practice and treatments administered for managing hyperkalaemia in a real-world setting in Greece. It will include approximately 12 public hospital and clinic based nephrology, or cardiology sites throughout the country. Sites and investigators will be selected so to represent the management of patients with CKD under dialysis or not, or with HF receiving Renin angiotensin aldosterone inhibitors/Mineralocorticoid receptor antagonists (RAASi/MRAs) therapy, and treated with sodium zirconium cyclosilicate (SZC) as per SmPC at a national level. The final selection of the participating sites will be based on a documented feasibility evaluation process that will assess physicians' qualifications, previous participation, and experience in similar clinical studies. Data will be obtained prospectively during the study visits as performed per standard clinical practice. Data regarding the patient's medical history will be collected retrospectively from patient medical charts records. Physicians will monitor eligible patients and will record their management according to their usual clinical practice. Only medical records available from the clinical practice and provided by the physicians will be used in this study as source documentation and the data will be entered into the electronic Case Report Form. Therefore, the collected data will reflect usual clinical practice. The study will enroll approximately 120 hyperkalaemia patients with serum potassium level >5.0 mmol/L, being treated with sodium zirconium cyclosilicate for hyperkalaemia at the time of enrolment as per SmPC, assigned in a 2:1:1 ratio to one of the following 3 groups: (1) CKD patients not on dialysis (60 patients), (2) CKD patients on dialysis (30 patients) and (3) HF patients receiving RAASi/MRAs therapy (30 patients), all consisting the study population. Patients will be followed for 6 months, with a 6-month recruitment period, for a total study duration of 12 months.
The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
This is a multicenter, single arm, open-label, Phase 2 study in high risk smoldering myeloma patients. The primary objective is to determine the efficacy of Elranatamab in patients with previously untreated high-risk SMM. The key-secondary objective is to determine the safety of Elranatamab in patients with previously untreated high-risk SMM.
The purpose of this study is to investigate the impact of the physiotherapist's communication on the clinical presentation of patients with chronic musculoskeletal pain.
This study is a 2-arm, multicenter, multinational, prospective, randomized, controlled clinical trial. Hospitalized subjects with blood cultures growing Gram negative bacilli (GNB) will be randomized 1:1 to have the positive blood cultures characterized using standard of care (SOC) antimicrobial susceptibility testing (AST) vs. a rapid AST method known as Reveal™ in addition to SOC AST. The purpose of the FAST trial is to evaluate whether use of a rapid phenotypic AST improves clinical outcomes compared to use of SOC AST methods in clinical settings with high resistance rates.
