Primary Outcome Measures
NameTimeMethod
Change From Baseline to the End of Maintenance Period in Total of Each Sum Score of UPDRS Part 2 and Part 3baseline, end of maintenance period

Mean change (LOCF) from baseline to the end of maintenance period in total of each sum score of UPDRS Part 2 and Part 3.

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 2 assesses 13 items and 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.

Secondary Outcome Measures
NameTimeMethod
Efficacy Rate in Total of Each Sum Score of UPDRS Part 2 and Part 3baseline, end of maintenance period

Effective rate (percentage of subjects with 20% or 30% decrease) (LOCF) in total of each sum score of UPDRS Part 2 and Part 3 at the end of maintenance period

Mean Change in UPDRS Part 2 Sum ScoreBaseline, every two weeks

Mean change (LOCF) from baseline in UPDRS Part 2 sum score at every two weeks after dosing.

UPDRS sub-scale Part 2 assesses 13 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.

Efficacy Rate in UPDRS Part 2 Sum ScoreBaseline, every two weeks

Effective rate (percentage of subjects with 20% or 30% decrease) (LOCF) in UPDRS Part 2 sum score at every two weeks after dosing.

UPDRS Part 3 Sum ScoreBaseline, every two weeks

Mean change (LOCF) from baseline in UPDRS Part 3 sum score at every two weeks after dosing.

UPDRS sub-scale 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.

Efficacy Rate in UPDRS Part 3 Sum ScoreBaseline, every two weeks

Effective rate (percentage of subjects with 20% or 30% decrease) (LOCF) in UPDRS Part 2 sum score at every two weeks after dosing.

UPDRS Part 1 Sum ScoreBaseline, every two weeks

MMean change (LOCF) from baseline in UPDRS Part 1 sum score at every two weeks after dosing.

UPDRS sub-scale Part 1 assesses 4 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.

UPDRS Part 4 Sum ScoreBaseline, every two weeks

Mean change (LOCF) from baseline in UPDRS Part 4 sum score at every two weeks after dosing.

UPDRS sub-scale Part 4 assesses 11 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.

Total of Each Sum Score of UPDRS Part 1, 2, 3, and 4Baseline, every two weeks

Mean change (LOCF) from baseline to the end of maintenance period in total of each sum score of UPDRS Part 1, 2, 3 and 4.

UPDRS sub-scale Part 1, 2, 3, and 4 assess 4, 13, 14, and 11 items respectively. 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.

The Modified Hoehn and Yahr StageBaseline, end of maintenance period

Mean change (LOCF) from baseline in the Modified Hoehn and Yahr Severity of Illness at the end of maintenance period. The Modified Hoehn and Yahr criteria are measured on the following 8-point scale for staging: 0, No signs of disease; 1, Unilateral disease; 1.5, Unilateral plus axial involvement; 2, Bilateral disease without impairment of balance; 2.5, Mild bilateral disease with recovery on pull test; 3, Mild to moderate bilateral disease, some postural instability, physically independent 4, Severe disability, still able to walk or stand unassisted; and 5, Wheelchair bound or bedridden unless aided.
