Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange From Baseline in the Total "On" Time Without Troublesome Dyskinesia Based on the 2-day Average of the Self-completed Home Diary for Motor Function Status (Hauser Diary)Week 26
The Hauser diary assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total "on" time without troublesome dyskinesia will be assessed and reported at endpoint.
SecondaryChange From Baseline in Total Daily "Off" Time Based on the 2-Day Average of the Self-Completed Home Diary for Motor Function Status (Hauser Diary)Week 26
The Hauser diary assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total daily "Off" time will be assessed and reported at endpoint.
SecondaryChange From Baseline in the Total "On" Time Without Troublesome Dyskinesia Based on the 2-day Average of the Self-completed Home Diary for Motor Function Status (Hauser Diary)Week 2, 5, 8, 11, 14, 18, 22, and 26
The Hauser diary assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total "on" time without troublesome dyskinesia will be assessed and reported at different time points.
SecondaryChange From Baseline in Total Daily "Off" Time Based on the 2-Day Average of the Self-Completed Home Diary for Motor Function Status (Hauser Diary)Week 2, 5, 8, 11, 14, 18, 22, and 26
The Hauser diary assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone). The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep. The total daily "Off" time will be assessed and reported at different time points.
SecondaryChange From Baseline in the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Parts I, II and III Individual ScoreWeek 26
The MDS-UPDRS rating tool was used to follow longitudinal course of Parkinson's Disease. It was made up of 4 parts: Part 1: Non-motor aspects of experiences of daily living (13 items. Score range: 0-52); Part 2: Motor aspects of experiences of daily living (13 items. Score range: 0-52); Part 3: Motor examination (18 items. Score range: 0-132); Part 4: Motor complications (6 items. Score range: 0-24. Part 4 was not collected in this trial). Each item has 0-4 rating on scale from 0 (normal) to 4 (severe). Higher values represent a worse outcome.
