Treatment and study plan

Rotigotine

Drug

Transdermal patch; Dose: 1 mg/24 h, 2 mg/24 h or 3 mg/24 h once daily depending on optimal dose; maximal dose is 3 mg/24 h.

Subjects start with a Rotigotine dose of 1 mg/24 h for 1 week. The dose can be increased weekly during Up-Titration Period until either the optimal or the maximal dose of 3 mg/24 h has been reached. Subjects will maintain the optimal/maximal dose during the 2-week Maintenance Period. Following the Maintenance Period, subjects will be de-escalated from their optimal dose by decreasing the dose by 1 mg/24 h every other day during Taper Period until complete withdrawal.

Other names: Neupro

Placebo

Drug

Transdermal patch; Patches matching to active treatment patches in size and appearance.

Up to 3 weeks of Titration,

2 weeks of Maintenance,

Up to 4 days of Taper Period.

Primary outcomes

  1. Ratio From Baseline to the End of the 2-week Maintenance Period in Periodic Limb Movement Index (PLMI)

    Time frame: From Baseline over the Up-Titration Period (up to 3 Weeks) to the end of the 2-Week Maintenance Period

    The PLMI is defined as Periodic Limb Movements (PLMs)/ total time in bed in hours. PLMs are measured by Polysomnography (PSG).

    The reduction of the PLMI is reflected in terms of the ratio from Baseline to the end of the Maintenance Period and was calculated as [PLMI at end of Maintenance Period (MP)] / [PLMI at Baseline].

    A PLMI Ratio <1 indicates an improvement from Baseline to the end of the 2-week MP.
