The specific objective is to examine the feasibility of conducting future large scale studies on the efficacy of MSDC-0160 in persons with mild Alzheimer's disease. Efficacy and safety will be assessed as follows:
- Estimate the effect size of 150 mg daily MSDC-0160 versus placebo on 3-month change in brain glucose utilization using FDG-PET pre-specified regions of interest analysis. The a priori regions of interest (ROI) will include five bilateral regions: posterior cingulate, parietal cortex (angular gyrus), lateral temporal cortex, medial temporal cortex, and anterior cingulate-medial frontal cortex.
- Estimate the effect size of MSDC-0160 versus placebo on 3-month change in brain glucose utilization, using FDG-PET voxel-based analysis.
- Estimate the effect size of MSDC-0160 treatment versus placebo on 3-month change in cognitive function as determined by global cognitive function on a neuropsychological battery of 19 tests.
- Estimate the effect size of MSDC-0160 versus placebo on 3-month change in cognitive function as determined by the ADAS-Cog subscale.
- Estimate the effect of 3-months of MSDC-0160 treatment versus placebo on a 9-item executive function scale.
- Explore whether baseline levels of peripheral inflammatory biomarkers (HMW adiponectin, TNFα, IL-6, hsCRP, and FFA) or genotypes including, but not limited to, the apolipoprotein ε4 allele explain the heterogeneity in baseline level of brain glucose utilization and, in MSDC-0160 users, 3-month brain glucose utilization.
- Explore whether changes in peripheral inflammatory biomarkers correlate with changes in 3-month brain glucose utilization in MSDC-0160 users.
- Investigate the safety of MSDC-0160 versus placebo using reports of early study termination and adverse events.

- Effects of MSDC-0160 on Cerebral Metabolic Glucose Rate or Placebo Over 12 Weeks in Pre-specified Regions of Interest Analysis Referenced to Cerebellum [ Time Frame: Days 1(baseline) and 91 ]Investigate the effect of 150 mg daily MSDC-0160 vs placebo on 3-month change in brain glucose utilization using FDG-PET pre-specified regions of interest analysis referenced to cerebellum, including five bilateral regions: posterior cingulate, parietal cortex (angular gyrus), lateral temporal cortex, medial temporal cortex, and anterior cingulate-medial frontal cortex. Results are reported as Standardized Uptake Value Ratios. A change from baseline in the metabolic rate of glucose that is ≥0 indicates maintenance of brain glucose utilization, whereas values <0 indicate a decline in brain glucose utilization.
- Change From Baseline in Global Cognitive Function Tests [ Time Frame: Days 1 (baseline) and 91 ]Change from baseline in cognitive function, as determined by global cognitive function on a neuropsychological battery of 19 tests, following 3 months treatment with MSDC-0160 versus placebo. A summary measure of global cognitive function was constructed by converting raw scores from 19 individual tests into z-scores as described by Bennett DA, et al., The Rush Memory and Aging Project: study design and baseline characteristics of the study cohort, Neuroepidemiology. 2005;25(4):163-175.
- Change From Baseline in Cognitive Function as Determined by the ADAS-Cog Subscale [ Time Frame: Days 1 (baseline) and 91 ]Alzheimer's Disease Assessment Scale - Cognitive Subscale, an assessment of cognitive ability. Scores on 11 individual tasks were summed to produce the reported total score, with a possible range of 0 (no impairment) to 70 (severe impairment).
- Change From Baseline in Cognitive Function as Estimate With the Executive Function Scale [ Time Frame: Days 1 (baseline) and 91 ]Estimate of the effect of 3-months of MSDC-0160 treatment versus placebo on a 9-item executive function scale. A summary measure of executive function was constructed by converting raw scores from 9 individual tests into z-scores as described by Bennett DA, et al., The Rush Memory and Aging Project: study design and baseline characteristics of the study cohort, Neuroepidemiology. 2005;25(4):163-175.
- Change From Baseline in HMW Adiponectin of MSDC-0160 or Placebo Over 12 Weeks [ Time Frame: Days 1(baseline) and 91 ]Estimate the effect of 150 mg daily MSDC-0160 versus placebo on levels of high molecular weight adiponectin. Increases in HMW adiponectin suggest improved insulin sensitivity.
