There are about 4313 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.
Researchers are looking for a better way to treat people with atrial fibrillation and prevent stroke or systemic embolism (blood clots travelling through the blood stream to plug another vessel). Atrial fibrillation is a condition of having irregular and often rapid heartbeat. It can lead to the formation of blood clots in the heart which can travel through the blood stream to plug another vessel, and like this lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from atrial fibrillation can involve extensive areas of the brain, it is important to prevent them. Blood clots are formed in a process known as coagulation. Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs) including apixaban. OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding. The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care with regard to the risk of bleeding. The main purpose of this study is to collect more data about how well asundexian works to prevent stroke and systemic embolism and how safe it is compared to apixaban in people with atrial fibrillation and at high risk for stroke. To see how well the study treatment asundexian works researchers compare: - how long asundexian works well and - how long apixaban works well after the start of the treatment. Working well means that the treatments can prevent the following from happening: - stroke and/or - systemic embolism. The study will keep collecting data until a certain number of strokes or embolisms happen in the study. To see how safe asundexian is, the researchers will compare how often major bleedings occur after taking the study treatments asundexian and apixaban, respectively. Major bleedings are bleedings that have a serious or even life-threatening impact on a person's health. The study participants will be randomly (by chance) assigned to 1 of 2 treatment groups, A and B. Dependent on the treatment group, the participants will either take the study treatment asundexian by mouth once a day or apixaban by mouth twice a day for approximately 9 - 33 months. Each participant will be in the study for approximately 9 - 34 months. There will be visits to the study site every 3 to 6 months and up to 7 phone calls. Those participants who do not want or are unable to have visits to the study site may join the study remotely in selected locations. The location name contains the abbreviation - DCT in such cases. During the study, the study team will: - take blood samples - do physical examinations - examine heart health using an electrocardiogram (ECG) - check vital signs such as blood pressure and heart rate - do pregnancy tests - ask the participants questions about their quality of life - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
Rapid antigen detection (RAD) tests are used to perform rapid diagnosis of SARS-CoV-2 infection based on a qualitative approach. RAD tests detect the viral antigen by the immobilized coated SARS-CoV-2 antibody placed on the device. The results of these tests are available in a short time, reducing the workload in diagnostic hospitals and laboratories and improving the turn-around time. EuGeni SARS-CoV-2 Antigen Rapid Diagnostic Test is an in vitro Diagnostic (IVD) medical device intended to be used for the qualitative detection of SARS-CoV-2 nucleocapsid antigen. The result from this IVD test identifies the presence or absence of the SARS-CoV-2 antigen as an aid for the diagnosis of COVID-19 infection.
A Phase 2, Open-Label Extension study to evaluate the long-term safety and tolerability of daxdilimab in participants with Systemic Lupus Erythematosus completing the treatment period of the RECAST SLE clinical study.
The purpose of this study is to evaluate the safety, pharmacokinetics, and effect on cardiac function of intravenous APD418 in adult participants with heart failure with reduced ejection fraction (HFrEF).
The purpose of this study is to evaluate the effect of guselkumab on coronary flow reserve (CFR), measured by transthoracic doppler-echocardiography, in participants with moderate-to-severe psoriasis and intermediate cardiovascular risk.
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. CD may cause tiredness, loose stools with or without bleeding, abdominal pain, weight loss, and fever. This study evaluates how safe and effective ABBV-154 is in participants treated for moderately to severely active CD. Adverse events and change in the disease activity will be assessed. ABBV-154 is an investigational drug being evaluated for the treatment of CD. In the induction period, there is a 1 in 5 chance that participants will be assigned to placebo. Depending on the dose received in the induction period, there is a 1 in 2 or 1 in 3 chance that participants will be assigned to placebo in the maintenance period. Around 265 participants 18-75 years of age with moderately to severely active CD will be enrolled in the study at approximately 200 sites worldwide. The study is compromised of a 12-week double-blind, placebo-controlled induction period, followed by either a 12-week double-blind re-induction period for non-responders or a 40-week double-blind placebo-controlled maintenance period for responders. In the maintenance period, responders will be randomized to receive subcutaneous placebo or ABBV-154 in 2 different doses every other week. Participants in the placebo group who are initial responders will receive ABBV-154 in the maintenance period. There may be higher treatment burden for participants in this trial compared to their standard of care due to study procedures. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
This was a placebo controlled, phase 3 study designed to evaluate the efficacy and safety of ligelizumab in participants with chronic inducible urticaria who are inadequately controlled with H1-antihistamines
This is a multicenter, randomized, open-label, Phase 2/3 study that will evaluate the efficacy and safety of bempegaldesleukin (BEMPEG; NKTR-214) combined with pembrolizumab compared with pembrolizumab monotherapy in patients with recurrent or metastatic HNSCC with positive PD-L1 expression (CPS ≥ 1).
The purpose of this study is to evaluate the efficacy and safety of XAV-19 drug in patients with moderate-to-severe COVID-19.
EU SolidAct is a randomized, multifactorial, adaptive platform trial for COVID-19 and emerging infectious diseases and pandemics. The purpose of this study is to evaluate the effect of a range of interventions to improve outcome of patients admitted to hospital with COVID-19. The platform is designed for running phase 2 and phase 3 trials, and with modular data capture (end point/safety data, biobanking, add-on studies) depending on the capacity of participating sites. The study consists of two parts with different primary end points depending on disease stage: EU SolidAct part A includes hospitalized patients with moderate disease, whereas EU SolidAct part B includes hospitalized patients with severe and critical disease.
