Number of Participants With Treatment-emergent Adverse Events (AEs)
Délai: Up to Day 35
|
Participants were treated for 28 days with either SCH 39641 12 Amb a 1-U or placebo, and the number with treatment-emergent AEs were recorded.
An AE is any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Treatment-emergent AEs are new AEs that occur after participants have been randomized into the trial, or existing AEs that occurred during Screening that increase in severity after randomization.
