Primary Outcome Measures
NameTimeMethod
Change From Baseline in the Percentage of "On" Time Without Dyskinesia Averaged Over Days 1 and 2 in Participants Treated With SUN N4057 and Those Treated With a PlaceboBaseline (Day-7) up to 2 days post-dose.

Improvement in motor complications associated with Parkinson's disease are measured as "on" (good medication response); OR "on with dyskinesia" (good medication response, but with superimposed involuntary movements that interfere with activities), OR "off" (poor medication response).

Secondary Outcome Measures
NameTimeMethod
Change From Baseline up to Day 2 in the Percentage of "on" Time Without Dyskinesia, as Assessed Over Hours 1 to 8 for Each Time Point in Participants Treated With SUN N4057 and Those Treated With a PlaceboBaseline (Day -7), Day 1, and Day 2 post-dose.

Improvement in motor complications associated with Parkinson's disease are measured as "on" (good medication response); OR "on with dyskinesia" (good medication response, but with superimposed involuntary movements that interfere with activities), OR "off" (poor medication response).

Percentage of "on" Time With Dyskinesia at Baseline up to Day 2, and the Change From Baseline in Participants Treated With SUN N4057 and Those Treated With a PlaceboBaseline (Day -7), Day 1, and Day 2 post-dose.

Improvement in motor complications associated with Parkinson's disease are measured as "on" (good medication response); OR "on with dyskinesia" (good medication response, but with superimposed involuntary movements that interfere with activities), OR "off" (poor medication response). Negative values indicate a decrease in "on" time from baseline to measured time point.

Change From Baseline up to Day 2 in the Average Abnormal Involuntary Movement Scale (AIMS) Total Score in Participants Treated With SUN N4057 and Those Treated With a PlaceboBaseline (Day -7), Day 1, and Day 2 post-dose.

The Abnormal Involuntary Movement Scale (AIMS) is an assessment of dyskinesia in patients with movement disorders. The AIMS was originally developed to assess neuroleptic-induced extrapyramidal symptoms but has also been applied to the assessment of dyskinesia in patients with Parkinson's disease. AIMS questions 1 to 7 rate the degree of dyskinesia on a 0 to 4 scale in the extremities, trunk, and face, where 0 is no dyskinesia (better outcome) and 4 is severe dyskinesia (worse outcome). The total score range is 0 (better outcome) to 28 (worse outcome). Higher scores indicate a worse outcome.

Mean SUN N4057 Plasma Pharmacokinetic Parameter of Observed Minimum Concentration (Cmin) Following Treatment With SUN N4057Day 1 pre-dose (Hour 0) up to Hour 24, and Hour 48 post-dose.

Cmin is the observed minimum concentration of SUN N4057 in the participant blood plasma sample after drug administration. Average of C24 and C48 \[ie, 24 hours after the initiation of infusion on Days 1 and 2. Cmin = average of (C24 and C48)

Mean SUN N4057 Plasma Pharmacokinetic Parameter of Observed Maximum Concentration (Cmax) Following Treatment With SUN N4057Baseline (Day 1 pre-dose) up to Hour 24, and Hour 48 post-dose.

Cmax is the observed maximum concentration of SUN N4057 in the participant blood plasma sample after drug administration.

Caverage is the mean concentration of SUN N4057 in the participant blood plasma sample obtained from the observed concentrations during the 2-day drug infusions (average of C1, C6, C12, C25, C30, and C36 \[ie, Hours 1, 6, 12, 25, 30, and 36 after the initiation of infusion on Day 1\]). Caverage = average of (C1, C6, C12, C25, C30, and C36)

AUCt is defined as the area under the drug concentration vs time curve from zero up to the last sampling point with a quantifiable drug concentration which is above the lower limit of quantification.

Treatment-Related Treatment-Emergent Adverse Events Reported Following Treatment With SUN N4057 or PlaceboBaseline up to Day 16 post-dose, up to approximately a total 12 months.

A treatment-emergent adverse event (TEAE) was defined as an Adverse Event (AE) that was new in onset or aggravated in severity or frequency following administration of the investigational agent. This included any change from the screening physical examination findings or results of diagnostic procedures (eg, laboratory test, ECG) that were clinically significant, eg, required diagnostic or therapeutic intervention beyond confirmation alone.
