This study will evaluate the effect of 150 mg MSDC-0160 taken daily for 90 days compared to the effect of placebo on changes in brain glucose utilization using FDG-PET and cognition in older persons with mild Alzheimer's disease.
Safety and tolerability of MSDC-0160 in this population will also be studied. These results will be used to design larger studies of MSDC-0160 in persons with mild Alzheimer's disease.
Note: The only available location for this Phase 2 clinical trial is Rush Memorial University Medical Center, Chicago, Illinois, United States, 60612. The study is limited to approximately 40 participants so if you are interested you should make contact now. Raj C. Shah, MD, Rush Memorial University Medical Center is the principal investigator.

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.
