- Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) [ Time Frame: Up to 12 months ]TEAEs were defined as those adverse events (AEs) that occurred from the first day of study drug to the last day of study drug + 2 days inclusive. An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product.AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
