Primary outcome measure(s)
Incidence of treatment-emergent adverse events (TEAEs) during the study — From Entry Visit up to the Safety Visit (up to 3 years) An adverse event (AE) is defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory finding) in study participants, users, or other persons, whether or not related to the investigational medicinal product (IMP).
