Outcome Measures

Primary Outcomes (1)

  • Change in Unified Parkinson's Disease Rating Scale (UPDRS) (Total Score (Sum of Parts I, II and III Ranges From 0 to 176))

    Outcome is defined as change in total Unified Parkinson's Disease Rating Scale (UPDRS) between the baseline visit and month 16 or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first. The UPDRS score has three components, each consisting of questions answered on a 0-4 point scale. Part I assesses mentation, behavior and mood; Part II assesses activities of daily living in the week prior to the designated visit; and Part III assesses motor abilities at the time of the visit. A total of 31 items are included in Parts I, II and III. Each item will receive a score ranging from 0 to 4 where 0 represents the absence of impairment and 4 represents the highest degree of impairment. Total score ranges from 0-176.

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

Secondary Outcomes (22)

  • Change in Modified Schwab & England Independence Scale From Baseline to 16 Months

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

  • Change in Modified Rankin Scale From Baseline to 16 Months

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

  • Change in PD Quality of Life Scale From Baseline to 16 Months

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

  • Change in Symbol Digit Modalities Test From Baseline to 16 Months

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

  • Change in Hoehn & Yahr Score From Baseline to 16 Months

    Baseline to 16 months or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first

  • +17 more secondary outcomes
