Primary Outcome Measures:
  • Percent Change From Baseline to the End of Treatment Period on the Action Myoclonus Score (Unified Myoclonus Rating Scale (UMRS) Section 4) [ Time Frame: From Baseline to End of Treatment Period (Week 14 or Early Discontinuation Visit) ] [ Designated as safety issue: No ]
    The range for Action Myoclonus Score (centrally read) is 0 (best) - 160 (worst). Percent change from Baseline = 100 X ((Baseline UMRS4 - Treatment UMRS4) / Baseline UMRS4). Baseline is defined as the last non-missing value prior to or on Randomization Visit.


Secondary Outcome Measures:
  • Percent Change From Baseline to the End of Treatment Period on the Functional Disability Score (Unified Myoclonus Rating Scale (UMRS) Section 5) [ Time Frame: Baseline to End of Treatment Period (Week 14 or Early Discontinuation Visit) ] [ Designated as safety issue: No ]
    The range for Functional Disability Score is 0 (best) to 28 (worst). Percent change from Baseline = 100 X ((Baseline UMRS5 - Treatment UMRS5) / Baseline UMRS5). Baseline is defined as the last non-missing value prior to or on Randomization Visit.

  • Percent Change From Baseline to the End of Treatment Period on the Stimulus Sensitivity Score (Unified Myoclonus Rating Scale (UMRS) Section 3) [ Time Frame: Baseline to End of Treatment Period (Week 14 or Early Discontinuation Visit) ] [ Designated as safety issue: No ]
    The range for Stimulus Sensitivity Score is 0 (best) to 17 (worst). Percent change from Baseline = 100 X ((Baseline UMRS3 - Treatment UMRS3) / Baseline UMRS3). Baseline is defined as the last non-missing value prior to or on Randomization Visit.

  • Percent Change From Baseline to the End of Treatment Period on the Myoclonus Patient Questionnaire (Unified Myoclonus Rating Scale (UMRS) Section 1) [ Time Frame: Baseline to End of Treatment Period (Week 14 or Early Discontinuation Visit) ] [ Designated as safety issue: No ]
    The range for Myoclonus Patient Questionnaire is 0 (best) to 44 (worst). Percent change from Baseline = 100 X ((Baseline UMRS1 - Treatment UMRS1) / Baseline UMRS1). Baseline is defined as the last non-missing value prior to or on Randomization Visit.

  • Global Evaluation Score (Investigator) at the End of Treatment Period [ Time Frame: End of Treatment Period (Week 14 or Early Discontinuation Visit) ] [ Designated as safety issue: No ]
    The Global Evaluation Scale Score (Investigator) ranges from 1 (Marked worsening) to 7 (Marked improvement).
