Measure Type Other Pre-specified
Measure Title UPDRS Part III OFF
Measure Description The UPDRS (Unified Parkinson's Disease Rating Scale) is a clinical rating scale that assesses the symptomatic burden of Parkinson's Disease. The scale has four main sections, and each item is scored from a 0 to a 4 (higher number is more severe manifestation). Part III is a subsection devoted to motor function, has 14 questions, resulting in a score range of 0 (unaffected) to 56 (severely affected). The scale is administered by a trained clinician, and patients were assessed in a practically defined "off" condition, 12 hours or more after the last administration of medication.
Time Frame Change from Baseline to 18 Month Visit

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Subjects who completed the 12-month double-blind posttreatment period of the study continued to undergo double-blind assessments every 3 months until the last subject had completed the end-of-study visit at month 12. The LOCF method was used to impute data at month 18 for the subjects who had blinded data through month 15.
