Rosiglitazone (Extended Release Tablets) As Monotherapy In Subjects With Mild To Moderate Alzheimer's Disease

The 11-item ADAS-Cog assessed a range of cognitive abilities including memory, comprehension, orientation in time and place and spontaneous speech. Items were evaluated by tests and clinician ratings on a 5-point scale. Scores ranged from 0-70 with higher scores indicates more dysfunction. Change from Baseline was calculated as value at scheduled time point minus Baseline value. Baseline is defined as value at W0. Estimated value was calculated by Active treatment minus Placebo. A hierarchical testing procedure was used to control for the two rosiglitazone dose groups and the three genetic subgroups. There was no adjustment for the donepezil versus placebo comparisons, which were included to assess the sensitivity of the trial to detect a treatment effect.

The ACQLI was an assessment of caregiver quality of life. This instrument consists of 30 questions exploring various aspects of carer's quality of life. Each of the questions had a two point response and the 30 questions were summed to provide a total score. Items are assumed to be unidimensional (i.e., represent a single variable) and are scored 0/1 (false/true) before summation into a total score with a 0-30 range. To ease comparisons between scales, ACQLI scores were transformed to range between 0-100 (100: worse). The assessments was performed at Baseline, W12 and W24.

The NPI assessed behavioral disturbances comprises 10 dimensions: delusions, hallucinations, dysphoria, apathy, euphoria, disinhibition, aggressiveness and agitation, irritability, anxiety and aberrant motor activity. The par. caregiver asked about behavior in the par. If Yes, the informant then rates both the severity on a 3-point scale, 1: mild to 3: severe (total range: 0-36) and the frequency using a 4-point scale, 1: occasionally to 4: very frequently. The total domain score was frequency × severity. The distress was scored on 5-point scale, 0: no distress to 5 - very severe or extreme. A total NPI score can be calculated by adding all domain scores together; NPI total score: from 0-144 and NPI distress score: from 0-60, all with higher scores indicating more severe behavioral disturbance.
