结局指标
主要结局
Unified Parkinson's Disease Rating Score (UPDRS) Part 3 Sum Score
时间窗: baseline, 16 weeks after dosing
Mean change (LOCF) from baseline in UPDRS Part 3 sum score (on state) at 16 weeks after dosing. UPDRS is a scale for monitoring Parkinson's Disease-related disability and impairment. The UPDRS consists of the following four sub-scales. Part 1: Mentation, Part 2: Activities of Daily Living, Part 3: Motor, Part 4: Complications. Part 3 assesses 14 items. Each item is scored from 0 (normal) to 4 (severe). The sum score serves as the sub-scale score. A higher score indicates a greater severity of symptoms. Thus a decrease in the scores means improvement.
