Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: LY03003
|
Drug: LY03003(Rotigotine,extended-release microspheres)
During the intervention, the initial dose was 14mg, and then was incremented in weekly units, 14mg each time, until the maximum dose of 56mg set in this study was reached 4 weeks after titration, the optimal therapeutic dose or the maximum tolerated dose was entered into the dosing maintenance period. After entering the maintenance period, no dose adjustment was performed, and the stable dose was maintained for 24 weeks
