Change in modified AIMS (Abnormal Involuntary Movement Scale) total score from baseline to Week 12
Tidsramme: 12 weeks
|
The modified AIMS is a scale used to assess dyskinesia. It focuses on six different parts of the body and rates abnormal movements from 0 (absence of dyskinesia to 4 (severe) (maximal score, 24). Change from baseline to Week 12 will be analyzed using the mixed effect repeated measures model (MMRM) including treatment, pooled center, week, treatment by week interaction as fixed effects and baseline total score as covariate with an unstructured covariance structure. |

|
The incidence rate of adverse events
Tidsramme: Monitored for the duration of the study which is 13 weeks
|
The occurrence of adverse events would be sought by non-directive questioning of the patient. Adverse events may also be detected when they are volunteered by the patient or through physical examination, laboratory test, or other assessments. AEs will be summarized by presenting, for each treatment group the number and percentage of patients having any adverse event, having an adverse event in each system organ class and having each individual adverse event by system organ class and preferred term. |

The change in total score and sub-score of UDysRS Parts I, II, III, and IV from baseline to Week 12
Tidsramme: 12 weeks
|
The UDysRS captures dyskinesia and has 4 parts: I: Historical Disability of On-Dyskinesia impact (max 44 pts); II: Historical Disability of Off-Dystonia impact (max 16 pts); III: Objective Impairment dyskinesia (max 28 pts); IV: Objective Disability based on Part III activities (max 16 pts). Higher scores mean greater severity. Change from baseline to Week 12 will be analyzed using mixed-effect repeated measure model (MMRM) including treatment, pooled center, week, treatment by week interaction as fixed effects and baseline total score as covariate with an unstructured covariance structure. |

|
Change in Lang-Fahn Activities of Daily Living Dyskinesia Scale (LFADLDS) total score from baseline to Week 12
Tidsramme: 12 weeks
|
The LFADLDS assesses the degree of dyskinesia interfering with activities of daily living. Specific definitions for severity rating codes (range, 0-4 for each task) will be provided for reproducibility of results. A higher score indicates more severe impairment. A patient and caregiver version of the revised LFADLDS will be used in this study. Change from baseline to Week 12 will be analyzed using MMRM including treatment, pooled center, week, treatment by week interaction as fixed effects and baseline total score as covariate with an unstructured covariance structure. |

Change in clinician-rated global impression of change (CGIC) score from baseline to Week 12
Tidsramme: 12 weeks
|
The CGIC provides investigator-rated assessment of change from baseline to assess disability due to dyskinesia. Change from baseline will be rated on a 7-point, Likert-type scale where 1 = markedly improved, 2 = moderately improved, 3 = minimally improved, 4 = unchanged, 5 = minimally worse, 6 = moderately worse, and 7 = markedly worse. The CGIC score at week 12 last observation carried forward (LOCF) will be analyzed using analysis of covariance (ANCOVA) model with treatment group, pooled center, and baseline CGIS (Clinical Global Impression of Severity) score as factors. |

A patient home diary developed and validated for use in PD patients will be used to record whether the patient is asleep, OFF, ON without dyskinesia, ON with troublesome dyskinesias, and ON with non-troublesome dyskinesia. Change from baseline to Week 12 will be analyzed using MMRM including treatment, pooled center, week, treatment by week interaction as fixed effects and baseline total score as covariate with an unstructured covariance structure. |

UPDRS assesses the disease state of PD. Question 32 assesses length of dyskinesias in percentage of the day. Question 33 assesses disability during the previous week (not disabling, mildly disabling, moderately disabling, severely disabling, completely disabling). Question 34 assesses painfulness of dyskinesias from 0 (no painful dyskinesias) to 4 (marked). The change will be analyzed using MMRM including treatment, pooled center, week, treatment by week interaction as fixed effects and baseline total score as covariate with an unstructured covariance structure. |

The MMSE is a test of cognitive dysfunction consisting of orientation, registration, attention-calculation, recall, and language administered by a health care professional. The MMSE results in total possible score of 30, with higher scores meaning better function. The change from baseline to endpoint at Week 12 in MMSE total score will be analyzed using LOCF ANCOVA with treatment group and pooled center as factors and the baseline score as a covariate. Treatment differences in the change from baseline for scores with 90% CI will be reported as descriptive statistics. |
