Trial Outcomes & Findings for A Study to Assess the Cognitive Effects of Fesoterodine in Elderly Subjects (NCT NCT01161472)

Last Updated: 2012-06-28

Results Overview

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.

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.

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.

Timeframe: 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.

Timeframe: 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.

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.
