Change From Baseline (W0) in Mean ADAS-Cog Total Score at W24 as a Function of APOE e4 Status in Apolipoprotein epsilon4 (APOE e4) Negative Cohort
Baseline (W0) and W24

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. The adjusted means were presented. 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.

Baseline (Week 0) and Week 48

The CDR-SB was a validated clinical assessment of global function in patients with AD. Impairment was scored in each of 6 cognitive categories on a scale in which none = 0, questionable = 0.5, mild = 1, moderate = 2, and severe = 3. The 6 individual category ratings, or "box scores", can be added together to give the CDR-Sum of Boxes which ranges from 0 to 18 (severe impairment). Change from Baseline was calculated as value at scheduled time point minus Baseline value. Baseline was defined as value a t Week 0. Estimated value was calculated by Active treatment minus Placebo. The adjusted means were presented. Primary inference will be based on the week 48 treatment differences obtained from the MMRM model.

CV death was defined as any death for which an unequivocal non-CV cause could not be established. CV death included death following heart failure, death following acute myocardial infarction (MI), sudden death, death due to acute vascular events, and other CV causes.

Baseline through End of Study (up to 7.5 years)

Par. with a stroke (fatal or non-fatal) event as determined by independent re-adjudication using the original RECORD endpoint definitions was recorded. A stroke event=hospitalization plus rapidly developed clinical signs of focal (or global) disturbance of cerebral function lasting more than 24 hours (unless interrupted by thrombolysis, surgery, or death), with no apparent cause other than a vascular origin, including par. presenting clinical signs/symptoms suggestive of subarachnoid haemorrhage/intracerebral haemorrhage/cerebral ischemic necrosis or cause of death adjudicated as stroke.

Number of Participants With Adverse Events (AE's)
From start of study medication (Wk 0) to Wk 50

An AE was defined as any untoward medical occurrence or clinical investigation in a participant, temporally associated with the use of a medicinal product, whether or not, considered related to the medicinal product. For marketed medicinal products, this also included failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. The number of participants with all AEs, drug related AEs, serious adverse events (SAEs), AE leading to permanent (prm) discontinuation (disc) of study drug or withdrawal were reported.

Change From Baseline (Day 1) in Global and Regional Indices of Cerebral Metabolic Rate of Glucose (CMRglu) at Month 12
Baseline (Day 1) and Month 12

Global CMRGlu index was related to grey matter of brain. Regional CMRGlu index was related to assessment of different regions of brain namely posterior cingulate gyrus, frontal lobe, parietal lobe, posterior temporal lobe, cerebellum, and medial temporal lobe. Evaluation of medial temporal lobe CMRGlu included assessment of medial anterior temporal lobe, paraHippocampal Ambiens gyrus, amygdala, and hippocampus. The regional CMRGlu index is directly proportional to the true metabolic rate of glucose. Baseline was defined as Day 1 of the 12 months treatment period. Change from Baseline is the value at indicated time point minus the Baseline value. Data has been presented for arithmetic mean; however, statistical analysis has been presented for adjusted or least square (LS) mean.
