ListOutcomeTime frameDescription
PrimaryChange From Baseline in Unified Parkinsons Disease Rating Scale (UPDRS) Parts II+III Score at Week 18Baseline and week 18
UPDRS total score ranges from 0 (best) to 160 (worst) and was calculated as the sum of Part II (activities of daily living, ranges from 0 to 52) and Part III (motor examination, ranges from 0 to 108). Reduction over time represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Percentage Off-time During Waking Hours at Week 18Baseline and week 18
Percentage off-time during waking hours based on patient diary data, percentage ranging from 0 (best case) to 100 (worst case). Off-time describes a period when the patient experiences increased parkinsonian symptoms (e.g. immobility or inability to move with ease). Reduction over time represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Duration of Off-time During Waking Hours at Week 18Baseline and week 18
Duration of off-time during waking hours based on patient diary data. Off-time describes a period when the patient experiences increased parkinsonian symptoms (e.g. immobility or inability to move with ease). Reduction over time represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryResponder in Percentage Off-time During Waking Hours at Week 18Baseline and week 18
Percentage off-time based on patient diary data, percentage ranging from 0 (best case) to 100 (worst case). Off-time describes a period when the patient experiences increased parkinsonian symptoms (e.g. immobility or inability to move with ease). Reduction over time represents an improvement. Responders were defined as patients with at least a 20 percent improvement relative to baseline.
SecondaryChange From Baseline in Percentage On-time Without Dyskinesia at Week 18Baseline and week 18
Percentage on-time without Dyskinesia based on patient diary data, percentage ranging from 0 (worst case) to 100 (best case). On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Increase in the percentage represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Percentage On-time With Non-troublesome Dyskinesia at Week 18Baseline and week 18
Percentage on-time with non-troublesome Dyskinesia based on patient diary data, percentage ranging from 0 (worst case) to 100 (best case). On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Dyskinesia qualified as non-troublesome if it did not interfere with function or did not cause meaningful discomfort. Increase in the percentage represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Percentage On-time Without or With Non-troublesome Dyskinesia at Week 18Baseline and week 18
Percentage on-time without or with non-troublesome Dyskinesia based on patient diary data, percentage ranging from 0 (best case) to 100 (worst case). On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Dyskinesia qualified as non-troublesome if it did not interfere with function or did not cause meaningful discomfort. Increase in the percentage represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Percentage On-time With Troublesome Dyskinesia at Week 18Baseline and week 18
Percentage on-time with troublesome Dyskinesia based on patient diary data, percentage ranging from 0 (best case) to 100 (worst case). On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Dyskinesia qualified as troublesome if it interfered with function or caused meaningful discomfort. Decrease in the percentage represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Duration of On-time Without Dyskinesia at Week 18Baseline and week 18
Duration of on-time without Dyskinesia based on patient diary data. On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Increase in the duration represents an improvement. Means are adjusted for treatment, centre and baseline.
SecondaryChange From Baseline in Duration of On-time With Non-troublesome Dyskinesia at Week 18Baseline and week 18
Duration on-time with non-troublesome Dyskinesia based on patient diary data, percentage ranging from 0 (worst case) to 100 (best case). On-time describes a period during which a patient was relatively free of Parkinsons symptoms (e.g. mobile or capable of moving with relative ease and independence). Dyskinesia qualified as non-troublesome if it did not interfere with function or did not cause meaningful discomfort. Increase in the duration represents an improvement. Means are adjusted for treatment, centre and baseline.
