We are delighted that you are participating in our study. This App is designed to simplify the timely and accurate documentation of your symptoms (e.g., acute viral rhinosinusitis or grass pollen allergy) and provide the most accurate data possible for clinical research. In addition, the use of study medication as well as the use of medication for symptom control can be documented depending on the study. Clinical trials aim to test the efficacy and tolerability of medications or medical treatments and thereby improve patient treatments. They provide important evidence to answer scientific questions. Therefore, it is important that you regularly record your symptoms, the use of the study medication as well as the effects on your quality of life. The exact specifications will be explained to you by the investigator/study team and are study-specific. Daily entries into the App will take a maximum of 5 minutes and can be made by checking the applicable boxes. To make it easier for you to remember entering your symptoms and/or study medication, you can activate alarms/ reminders in this App. The results of the clinical trial will be communicated to you by your investigator. The CCC STUDY Diary App can only be used in the context of a clinical study. You will receive the login information and password from your investigator/ study team as soon as you participate in one of these studies.
