Part 1: Percentage of SAD Participants With Adverse Events (AEs) |
An AE is any untoward medical occurrence in a clinical investigation healthy volunteer (HV)/participant administered a pharmaceutical product, regardless of causal attribution. 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, any new disease or exacerbation of an existing disease (a worsening in the character, frequency, or severity of a known condition and recurrence of an intermittent medical condition (e.g., headache) not present at baseline. |
