Timeline
Interventions
Apokyn will be titrated to an optimum dose which reproduces 90% of the subjects' "best on" UPDRS score during the Initiation Period. During the APOKYN Treatment Period, subjects will inject the dose identified in the initiation period once daily at the time of their normal scheduled L-Dopa dose (L-Dopa will be delayed by 40 minutes).
Subjects on a stable L-Dopa regimen will be entered into the study. For the L-Dopa Baseline Period through the Initiation Period, subjects will continue their normal L-Dopa dosing regimen. During the APOKYN Treatment Period, subjects will replace their normally scheduled first morning L-Dopa dose with an APOKYN injection, and then administer their normal first morning L-Dopa dose 40 minutes later.
Following the L-Dopa Baseline Period, subjects will initiate trimethobenzamide treatment TID for a minimum of 3 days during a Anti-Emetic Pretreatment Period. Subjects will continue trimethobenzamide therapy TID through the duration of the APOKYN Initiation Period and APOKYN Treatment Period.
