Timeframe: Baseline to Week 24 (or early discontinuation)

Population: Modified intent-to-treat population: all participants who were randomized, received at least 1 dose of study drug and had at least 1 postbaseline MoCA assessment.

The MoCA assesses 8 cognitive areas: visuospatial/executive, naming, memory, attention, language, abstraction, delayed recall, and orientation. Scores range from 0 (worst) to 30 (best).

Population: Modified intent-to-treat population: all participants who were randomized, received at least 1 dose of study drug and had at least 1 postbaseline PDAQ assessment.

The PDAQ is a 15-item questionnaire that assesses the patient's difficulty with activities of daily living. The total score has a range of 0 (no impairment) to 60 (severe impairment).

SECONDARY outcome

Timeframe: Week 24 (or early discontinuation)

Population: Modified intent-to-treat population: all participants who were randomized, received at least 1 dose of study drug and had at least 1 postbaseline ADCS MCI-CGIC assessment. n=number of participants with the given assessment.

The ADCS MCI-CGIC score is generated in the context of a semi-structured interview and is an indication of the change in the participant's global status, cognition, behavior, and functional abilities (FA) on a 7-point scale, with the best score being 'marked improvement' and the worst being 'marked worsening.'

SECONDARY outcome

Timeframe: Baseline to Week 24 (or early discontinuation)

Population: Modified intent-to-treat population: all participants who were randomized, received at least 1 dose of study drug and had at least 1 postbaseline UPDRS Motor Subscale (Part 3) assessment.

UPDRS Part 3 (motor examination subscale) comprises 14 items assessing the motor disabilities of the patient at the time of the visit. The participant's speech, facial expressions, ability to arise from a chair (with arms folded), posture, gait, postural stability (retropulsion test), and body bradykinesia and hypokinesia are assessed. In addition, the following evaluations require assessment of the face, neck or extremities: tremor at rest, action or postural tremor of hands, rigidity, finger taps, hand movements (open and close), rapid alternating movements of hands (pronation and supination), and leg agility (tap heel on ground). This evaluation is performed while the participant is in the 'on' phase. Each item is assessed on a scale from 0 (normal, absent, or none) to 4 (severe impairment), which are summed to get the sub-scale score. The total scale is 0-57 with a higher score indicating more severe symptoms; a decrease in the scores indicates improvement.

SECONDARY outcome

Timeframe: Baseline to week 24 (or early discontinuation)

Population: Modified intent-to-treat population: all participants who were randomized, received at least 1 dose of study drug and had at least 1 postbaseline UPDRS ADL Subscale (Part 2) assessment.

UPDRS Part 2 (ADL subscale) comprises 13 items evaluating the impact of PD on patients' ADL (in both the on and off states) in the week prior to the visit. The following 13 ADL are assessed: speech, salivation, swallowing, handwriting, cutting food and handling utensils, dressing, hygiene, turning in bed and adjusting bed clothes, falling (unrelated to freezing), freezing when walking, walking, tremor, and sensory complaints related to Parkinsonism. Each item is assessed on a scale from 0 (normal, absent, or none) to 4 (severe impairment), which are summed to get the sub-scale score. The total scale is 0-52 with a higher score indicating more severe symptoms; a decrease in the scores indicates improvement.
