Primary Outcome Measures
NameTimeMethod
Change in off time per day compared with the baseline value derived from the three-consecutive-day patient diary card information completed prior to visit 1 and prior to visits 5 and 6 during the At-Home dosing period and the maximum change in total UPDRS III score from pre-dose to post-dose during the In-Clinic dosing titration period.
Secondary Outcome Measures
NameTimeMethod
1. Proportion of off events per day aborted by study treatment<br>2. Interval between dose administration and onset of on state<br>3. Period from onset of on state to return to an off state<br>4. Mean daily duration in on without dyskinesias<br>5. Mean daily duration in on with non-troublesome dyskinesias<br>6. Mean daily duration in on with troublesome dyskinesias<br>7. Time taken for the study medication to start working and the period of time when the study medication was working<br>8. Mean number of off episodes per day<br>9. Mean daily period in off state<br>10. Mean daily period in any on state<br>11. Mean daily period asleep<br><br>Safety parameters:<br>12. Incidence of treatment-emergent AEs<br>13. Changes in laboratory tests and physical examination<br>14. Changes in vital signs, ECG, forced vital capacity (FVC)/FEV1 <br><br>All measured from screening to the end-of-treatment or close out visit.
