Number of Participants Experiencing Treatment-emergent Adverse Events Secondary · Day 1 through Day 6

An adverse event (AE) was any untoward medical occurrence in a participant that occurred either before dosing or once an investigational medicinal product (IMP) had been administered, including occurrences which were not necessarily caused by or related to that product. Treatment-emergent adverse events were AEs that commenced during/after the first administration of IMP or commenced before first administration of IMP, that is, a pre-dose AE or existing medical condition, but worsened in intensity during exposure to IMP.
