Today is the first World Patient Safety Day worldwide. In order to protect the safety and the best interests of patients in clinical studies, we implement the highest ethical standards and the appropriate regulations in all our studies. This is how we gain the trust of our customers and patients, even when conducting clinical studies with children. Recently, MEDIACC submitted a comprehensive ethical application for a study with an innovative medical device with professional athletes. By carefully choosing the endpoints and intensively training the study centres we can make sure that the study conduct will be performed according to the highest safety standards.
