Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years to 85 years (ADULT, OLDER_ADULT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Unified Dyskinesia Rating Scale (UDysRS)
Time Frame: 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.
up to 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient diaries
Time Frame: 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.
up to 12 weeks
Unified Parkinson's Disease Rating Scale (MDS-UPDRS)
Time Frame: 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.
up to 12 weeks
Clinical Global Impression
Time Frame: 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
up to 12 weeks
