Change From Baseline in the Unified Dyskinesia Rating Scale (UDysRS) Score at Week 12 [ Time Frame: Baseline to Week 12 ]
The UDysRS is a dyskinesia rating scale from 0-104; it evaluates involuntary movements associated with PD. A higher score indicates more severe PD. The UDysRS was measured at Baseline and Weeks 2, 8, 12, 18, and 24.

  • Change From Baseline in the Unified Dyskinesia Rating Scale (UDysRS) Score at Week 24 [ Time Frame: Baseline to Week 24 ]
    The UDysRS is a dyskinesia rating scale from 0-104; it evaluates involuntary movements associated with PD. A higher score indicates more severe PD. The UDysRS was measured at Baseline and Weeks 2, 8, 12, 18, and 24.
  • Change in the Standardized PD Home Diary (ON Time Without Troublesome Dyskinesia, ON Time With Troublesome Dyskinesia, OFF Time) [ Time Frame: Baseline (BL) to Week 12 (W12) and Week 24 (W24) ]
    A PD home diary was used to score 5 different conditions in 30-minute intervals: ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia. The results were based on 2 consecutive 24-hour diaries taken prior to the day of randomization and prior to the Week 2, 8, 12, 18, and 24 visits.
  • Change in the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Combined Score (Parts I, II, and III) [ Time Frame: Baseline (BL) to Week 12 (W12) and Week 24 (W24) ]
    The MDS-UPDRS Parts I, II, and III examined non-motor experiences of daily living, motor experiences of daily living, and motor examination, respectively. Each Part contains items or questions that were each rated on a scale from 0 (normal) to 4 (severe). The Combined Parts I, II, and III (representing the sum of the individual scores from Parts I, II, and III) has a scale range of 0-236. Higher scores, whether for individual Parts or the sum of the combined Parts, indicate more severe PD.
  • Clinician's Global Impression of Change (CGI-C) in Overall PD Symptoms [ Time Frame: Baseline to Week 12 and Week 24 ]
    The CGI-C consisted of a single question that assessed the investigator's global impression of the subject's change from Baseline in overall PD symptoms, including but not limited to LID. The CGI-C required that the investigator rate the extent to which the subject's PD had improved or worsened (from marked worsening to marked improvement). The CGI-C was assessed at Baseline and Weeks 2, 8, 12, 18, and 24.
  • Change in the standardized PD home diary (ON time without dyskinesia, ON time with troublesome dyskinesia, OFF time) [ Time Frame: Baseline to week 12 ]
  • Change in the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) [ Time Frame: Baseline to week 12 ]
  • Clinician's Global Impression of Change in overall PD symptoms [ Time Frame: Baseline to week 12 ]

ADS-5102 for the Treatment of Levodopa Induced Dyskinesia (EASE LID Study)
Efficacy and Safety of ADS-5102 (Amantadine HCl) Extended Release Capsules for the Treatment of Levodopa Induced Dyskinesia in Parkinson's Disease Patients (EASE LID Study)

This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance.

In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.
