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 was to establish safety and efficacy of ligelizumab in adolescent and adult subjects with Chronic Spontaneous Urticaria (CSU) who remain symptomatic despite standard of care treatment by demonstrating better efficacy over omalizumab and over placebo. The study population consisted of 1,072 male and female subjects aged ≥ 12 years who were diagnosed with CSU and who remained symptomatic despite the use of H1-antihistamines. This was a multi-center, randomized, double-blind, active- and placebo-controlled, parallel-group study. There was a screening period of up to 28 days, a 52 week double-blind treatment period, and a 12 week post-treatment follow-up period.
The researchers are doing the study to see if semaglutide may reduce the risk of having cardiovascular events in patients with overweight or obesity and with prior cardiovascular disease. The participant will either get semaglutide (active medicine) or placebo ("dummy" medicine). Which treatment the participants get is decided by chance. The participant's chance of getting semaglutide or placebo is the same. The participant will get the study medicine in a pen. The participants will need to use the pen to inject the study medicine in a skinfold once a week. The study will last for about 2.5 to 5 years. Participants will have up to 25 clinic visits with the study doctor.
Usage of osmotic agents is a standard practice in neuroanesthesia since cerebral edema is a very common situation for patients with pathology in the brain. Cerebral edema is defined as the accumulation of fluid in the intracellular or extracellular compartments of the brain. Among other situations that have nothing to do with the brain, a supratentorial pathology such as a tumor, traumatic injury or an aneurysm, will lead to disruption of blood-brain barrier, and energy crisis of the cells that will cause mainly vasogenic and cytotoxic cerebral edema. The most common monitoring method for "measuring" cerebral edema is ICP (intracranial pressure) in which normal values are (with differences in the bibliography) 10-15 mmHg. The osmotic agents used most in neuroanesthesia are mannitol 20% and hypertonic NaCl 7.5% or 3%. Their brain relaxation effectiveness is supposed to be quite the same between the two different agents. Their main difference is that mannitol induces diuresis. Also, electrolyte disorders are another possibility after mannitol infusion. On the other hand, NaCl 7.5% causes vasodilation, does not induce diuresis and hemodynamically, even though it reduces SBP, it raises CO because of its excessive vasodilation. But both reduce cerebral edema due to the change of osmotic pressure in the vessels, that leads to extracting water from brain cells. A supratentorial craniotomy is de facto worsening the oxygenation and metabolism condition of the surgical site, adding to the problem the intracranial pathology causes in the first place. So if oxygen provided is low and the metabolic rate is high, the rate of anaerobic metabolism will raise. Measuring the oxygen in the jugular bulb is the most reliable monitoring method of cerebral oxygenation and metabolism. It becomes evident that optimization of cerebral oxygenation during a craniotomy will possibly affect the outcome of a patient, by improving it. So, if any superiority of one osmotic agent over the other could be demonstrated this will be very helpful in the decision making in routine clinical practice.
The primary objective of this study is to assess the overall safety profile of idelalisib monotherapy in patients with refractory follicular lymphoma (FL).
Background: The exit strategy after ureteroscopy for stone treatment remains a topic for discussion. Current EAU guidelines on urolithiasis state that postoperative stenting is indicated in patients at increased risk of postoperative complications. Stenting is not considered necessary in all other cases, and after uncomplicated procedures. Objective: To analyse the postoperative ureteral stenting strategy in clinical practice looking at the indication, type of stents used and the duration of stenting after ureteroscopy for stone treatment. Furthermore, the investigators will examine in what setting the stents are being removed postoperatively. Study design: This study is a prospective, observational, international, multicentre registry study executed by uCARE. Study population: All patients >18 years with a ureter or renal stone who are planned for ureteroscopic treatment by semi-rigid and/or flexible ureteroscopy are eligible for this study.
To detect any changes in Quality of Life in patients with benign thyroid diseases who undergo thyroidectomy compared to patients with benign thyroid diseases and conservative treatment and healthy subjects.
The principal aim of the study is to determine whether the hemodynamic parameters measured with the two methods -impedance cardiography and applanation tonometry- can be predictive of the antihypertensive effect of two different classes of drugs, ATII antagonists and diuretics. The drugs that will be used in the study are olmesartan and chlorthalidone and the duration of the study is 12 months. The other basic aim of the study is to determine whether there is a difference (>6mmHg) between the two drugs regarding the reduction of the mean 24hour blood pressure and the effect of them on the hemodynamic parameters. The hemodynamic parameters that will be measured by applanation tonometry are augmentation index, central blood pressure and pulse wave velocity. The hemodynamic parameters that will be measured by impedance cardiography are cardiac index, thoracic fluid content index, systemic vascular resistance index and others.
This study is designed to evaluate the efficacy, safety, and pharmacokinetics of UTTR1147A compared with vedolizumab and with placebo in the treatment of participants with moderate to severe UC. This study will consist of two parts, Part A and Part B. Part A will test the induction of clinical remission and Part B will test the durability of clinical remission.
This study will look at the change in the participant's body weight from the start to the end of the study. This is to compare the effect on body weight in people taking semaglutide (a new medicine) and people taking "dummy" medicine. In addition to taking the study medicine, the participant will have talks with study staff about healthy food choices, how to be more physically active and what else the participant can do to lose weight. Overweight and obesity is associated with an increased risk of type 2 diabetes. Therefore, weight loss has shown to have a beneficial impact on the blood sugar levels. The participant will either get semaglutide or "dummy" medicine - which treatment the participant get is decided by chance. The participant will need to take 2 injections at the same time once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study will last for about 1.5 years
The main purpose of this study was to evaluate the impact on pyrexia-related outcomes of an adapted pyrexia adverse event (AE)-management algorithm, as well as safety, efficacy and health-related outcomes.
