Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Mean Change From Baseline in Total Daily OFF Time (Hours) During Open-label Extension Study | Baseline, Week 0, Week 12, Week 24, Week 36, Week 52, Week 78, Week 104, Week 130, Week 156 | OFF state is when medication has worn off and is no longer providing benefits with regard to stiffness, slowness, and tremor. This outcome measure was based on data collected through use of a patient diary. |
| Secondary | Mean Change From Baseline in Total Daily ON Time (Without Dyskinesias or With Non-troublesome Dyskinesias) (Hours) During Open-label Extension Study | Baseline, Week 0, Week 12, Week 24, Week 36, Week 52, Week 78, Week 104, Week 130, Week 156 | ON state is when medication is providing benefits with regard to stiffness, slowness, and tremor. This outcome measure was based on data collected through use of a patient diary. |
| Secondary | Mean Change From Baseline in UPDRS Part III (Motor) Score in ON State (Hours) During Open- Label Extension Study | Baseline, Week 0, Week 12, Week 24, Week 36, Week 52, Week 78, Week 104, Week 130, Week 156 | Unified Parkinson's Disease Rating Scale (UPDRS) is a standardized assessment of the symptoms and signs of Parkinson's Disease. Part III assesses motor activity, based on 14 items, such as gait, facial expression, and rigidity. Participants receive a score of 0-4 points per item, with a higher score indicating more severe symptoms. Range of possible total scores, 0 to 56. ON state is when medication is providing benefits with regard to stiffness, slowness, and tremor. |
