Conditions
Brief summary

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Unified Dyskinesia Rating Scale (UDysRS) | up to 12 weeks | The change from baseline to day 84 of treatment in the sum of the items comprising the Unified Dyskinesia Rating Scale (UDysRS). The UDysRS is administered to assess dyskinesia. The scoring range is 0-104, where higher score means more dyskinesia. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient diaries | up to 12 weeks | Change in daily OFF-time as assessed with patient diaries from run-in to day 84. This is a self administered diary where patients assess their motor state every half hour during 24 hours. |
| Unified Parkinson's Disease Rating Scale (MDS-UPDRS) | up to 12 weeks | Change in Unified Parkinson's Disease Rating Scale (MDS-UPDRS) total score of part III from Baseline (Day 1) to day 84. The part III of the MDS-UPDRS assess motor function in best on phase. The score range is 0-132, where a higher score means more severe motor impairment. |
| Clinical Global Impression | up to 12 weeks | Change score is an ordinal measure of change with a range of 0 (not assessed) to 7 (very much worse). A score of 4 is associated with no change |
