Trial Outcomes & Findings for Efficacy and Safety of Galantamine for Improving Dysfunction in People With Bipolar Disorder (NCT NCT00741598)

NCT ID: NCT00741598

Last Updated: 2017-05-02

Results Overview

CVLT is a test measuring verbal learning and verbal memory. Subjects are expected to remember a list of words. They are asked to repeat the words remembered 5 times (5 trials). Each of the words correctly remembered, in each trial, is marked as 1 point. The outcome measures presented are: CVLT Total Trials 1-5, Baseline = Number of total words remembered, sum of trials 1-5, at baseline CVLT Total Trials 1-5, Week 16 = Number of total words remembered, sum of trials 1-5, at week 16.

WCST (Wisconsin Card Sorting Test) is a neuropsychological test measuring the ability to display flexibility in the face of changing schedules of reinforcement. Subjects are presented with cards and requested to match them. Unbeknownst to the subject, the matching rules change while the test is delivered. The test measures subjects' ability to understand the new rules. The outcome measures presented are Total correct baseline = total correct card choices at baseline Total errors baseline = total erroneous card choices at baseline Total correct week 16 = total correct card choices at week 16 Total errors baseline = total erroneous card choices at week 16

Conner's CPT (Conner's Continuous Performance Task) is a neuropsychological test that measures a person's sustained and selective attention. Subjects are instructed to click the space bar when they are presented with any letter except the letter "X". The person must refrain from clicking if they see the letter "X" presented. Clicking to the letter "X" is a commission error, not clicking to other letters are omission errors. The outcome measures presented are Total number of errors = Total number of omission + commission errors This outcome measure is presented at each study visit (baseline, week 4, week 8, week 12, and week 16)

The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) is a self-report instrument designed to measure the degree of enjoyment and satisfaction experienced by subjects in various areas of daily functioning. There are 16 areas of functioning, each scored from 1 (very poor) to 5 (very good). The range of scores is 16-80, with lower scores representing lower functioning and satisfaction. The outcome measures presented are Q-LES-Q Total score = Sum of all scores from all 16 areas of functioning
