All negative changes in health during the study will be treated and recorded during the study.

AE: any untoward medical occurrence in a participant that does not necessarily have a causal relationship with this treatment. SAE: an event that results in the death of a subject, is life threatening, results in hospitalization or prolongation of hospitalization, is a congenital anomaly, results in persistent or significant disability/incapacity, or other important medical event. Severity was rated as mild, moderate, or severe. AEs of special interest included: device-associated gastrointestinal disorders; cardiovascular fatalities; aspiration including aspiration pneumonia; a diagnosis of peripheral polyneuropathy (axonal, demyelinating or mixed type); possible symptoms of peripheral polyneuropathy; clinically significant weight loss. 'AEs at least possibly related' are defined as those that were assessed by investigator as probably related or possibly related.

High potentially clinically significant Bazett's heart rate-corrected QT interval (QTcB) values were: 450 msec for males / 470 msec for females.

Participants were video recorded a total of 10 times for 1 to 2 minutes every 60 minutes while performing a standardized sequence of motor tasks: rest, finger taps, rapid alternating movement of hands, arising from chair and gait, including confirmation of postural stability. Based on these video recordings, a Video Evaluation Committee consisting of 3 neurologists individually evaluated the following Video Assessment and Treatment Response Scale (TRS) under blinded conditions: Finger Taps, Rapid Alternating Movement of Hands, Arising from Chair, Gait, Body Bradykinesia and Hypokinesia, Dyskinesia. The average of the neurologists' evaluations was calculated as a percentage of ratings in the "Normal" state (ie, "mild OFF" to "ON with mild dyskinesia") on the TRS I (total 10 assessments per day).
