Number of Participants With Adverse Events (AEs) and Treatment Related AEsUp to 6 yearsAn AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, regardless of causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
