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.

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
Computer Based Objective Cognition Testing (CogState) Detection Speed
Time Frame: Baseline
Detection speed: a cognitive test which assessed psychomotor function. A playing card was presented face up in the center of the screen. As soon as this happened, the participant was to press the 'Yes' key. The outcome measure was speed of performance; mean of the log10 transformed reaction time for correct responses [measured in log10 milliseconds (MS)]. Lower scores meant a better performance.
Baseline
Change From Baseline in Computer Based Objective Cognition Testing (CogState) Detection Speed on Day 6
Time Frame: Baseline and Day 6
Detection speed: a cognitive test which assessed psychomotor function. A playing card was presented face up in the center of the screen. As soon as this happened, the participant was to press the 'Yes' key. The outcome measure was speed of performance; mean of the log10 transformed reaction time for correct responses [measured in log10 milliseconds (MS)]. Lower scores meant a better performance.
Baseline and Day 6

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
CogState Identification Speed
Time Frame: Baseline
Identification speed: a cognitive test which assessed visual attention. A playing card was presented face up in the center of the screen. As soon as this happened, the participant had to decide whether the card was red or not. The outcome measure was speed of performance; mean of the log10 transformed reaction time for correct responses (measured in log10 MS). Lower scores meant a better performance.
Baseline
Change From Baseline in CogState Identification Speed on Day 6
Time Frame: Baseline and Day 6
Identification speed: a cognitive test which assessed visual attention. A playing card was presented face up in the center of the screen. As soon as this happened, the participant had to decide whether the card was red or not. The outcome measure was speed of performance; mean of the log10 transformed reaction time for correct responses (measured in log10 MS). Lower scores meant a better performance.
Baseline and Day 6
CogState One Card Learning
Time Frame: Baseline
One card learning: a cognitive test which assessed visual learning. Participants were to remember which cards were previously shown in a task. The outcome measure was accuracy of performance; arcsine transformation of the square root (sqrt) of the proportion of correct responses. Higher scores meant a better performance.
Baseline
Change From Baseline in CogState One Card Learning on Day 6
Time Frame: Baseline and Day 6
One card learning: a cognitive test which assessed visual learning. Participants were to remember which cards were previously shown in a task. The outcome measure was accuracy of performance; arcsine transformation of the square root (sqrt) of the proportion of correct responses. Higher scores meant a better performance.
Baseline and Day 6
CogState Continuous Paired Associate Learning (CPAL)
Time Frame: Baseline
CPAL: a cognitive test which assessed visual episodic learning. Participant was to learn and remember picture locations on the screen and was to tap the target on the central location to begin. As each picture was revealed, the participant was to remember where the picture was located and tap that location. The outcome measure was the number of errors made in correctly placing each of the 4 patterns in their location 4 times. Lower scores meant a better performance.
Baseline
Change From Baseline in CogState CPAL on Day 6
Time Frame: Baseline and Day 6
CPAL: a cognitive test which assessed visual episodic learning. Participant was to learn and remember picture locations on the screen and was to tap the target on the central location to begin. As each picture was revealed, the participant was to remember where the picture was located and tap that location. The outcome measure was the number of errors made in correctly placing each of the 4 patterns in their location 4 times. Lower scores meant a better performance.
Baseline and Day 6
CogState Groton Maze Learning Task (GMLT)
Time Frame: Baseline
GMLT: a cognitive test which assessed executive function. Participant was shown a 10 x 10 grid of tiles on a computer touch screen. A 28-step pathway was hidden among 100 possible locations. The participant was instructed to move 1 step from the start location and then continue 1 tile at a time, toward the end to find the pathway. The outcome measure was total number of errors made in attempting to learn the same hidden pathway on 5 consecutive trials at a single session. Lower scores meant a better performance.

The outcome measure was total number of errors made in attempting to learn the same hidden pathway on 5 consecutive trials at a single session. Lower scores meant a better performance.
Baseline and Day 6
Rey Auditory Verbal Learning Test (RAVLT)
Time Frame: Baseline
RAVLT evaluates a wide diversity of functions: short-term auditory-verbal memory, rate of learning, learning strategies, retroactive, and proactive interference, presence of confabulation of confusion in memory processes, retention of information, and differences between learning and retrieval. Assessment of RAVLT is between 10 to 15 minutes; Performance variable: the sum of the number of words recalled successfully on the delayed recall trial. Higher score meant a better performance.
