Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)Primary· A1281201: Day 1 up to 35 days after last dose of study medication (maximum up to 31 Weeks)
An adverse event (AE) was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship to it. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/ incapacity; congenital anomaly. AEs included both serious and all non-serious AEs.

BMI z-score was reported using the Children's Hospital of Philadelphia z-score calculator. Z-score is a statistical measure to describe whether a mean was above or below the standard. A z-score of 0 is equal to the mean and is considered normal. Lower numbers indicate values lower than the mean and higher numbers indicate values higher than the mean. Higher values are indicative of higher BMI.

SARS: 10-item clinician rated instrument to assess parkinsonian symptoms and related extrapyramidal side effects. All 10 items were anchored on a 5-point scale: range 0 (absence of condition, normal) to 4 (the most extreme form of condition). Total score is sum of individual item scores, ranged from 0 (normal) to 40 (most extreme symptoms and effects); higher score indicates more affected. Rows with only non-zero data/values for change in SARS total score at specified time points, for at least 1 reporting arm, are reported below.
