Timeframe: Day 1 to Day 15

Population: The safety set includes all participants who received at least 1 dose of study drug.

An AE was defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it did not necessarily have to have a causal relationship with this treatment. The different categories of intensity (severity) were characterized as follows: Mild: The event was transient and easily tolerated by the participant. Moderate: The event causes the participant discomfort and interrupted usual activities. Severe: The event causes considerable interference with the participant's usual activities.
