Study Stopped
Upon review it was determined that the study terminated early due to lack of funding. Study never reached enrollment target and was administratively closed out by the Albert Einstein College of Medicine IRB.

Outcome Measures
Primary Outcomes (1)
Tissue Gene Expression Using RNA Sequencing (RNA-Seq)
Difference in gene expression in muscle and abdominal adipose tissue using RNA-Seq were to have been evaluated to assess the effects of absorbed metabolites on tissues. Muscle and adipose are key metabolic tissues that undergo significant age-related changes and play an active role in the pathogenesis of aging. Muscle and abdominal adipose tissue samples were obtained and homogenized with tissue homogenizer. Subsequent mRNA extraction and analysis of gene expression (RNA seq) was conducted using multiplexed 100bp single-end sequencing. Differential expression between samples and after acarbose and after placebo were to have been determined using a negative binomial model approach implemented in the DESeq package. Results were to have been summarized by study arm and subsequently analyzed.
10 weeks
Secondary Outcomes (2)
Serum microRNA (miRNA)
At the end of 10 week treatment period (Visit 4) and at 22 weeks (Visit 6) following enrollment
Fecal Microbiome for 16s Ribosomal DNA (rDNA) Gene Sequencing
At the end of 10 week treatment period (Visit 4) and at 22 weeks (Visit 6) following enrollment
Study Arms (2)
Acarbose first
OTHERParticipants will take acarbose three times daily for 10 weeks (titration over 4 weeks, maintenance 6 weeks). After a two week washout, participants will take placebo three times daily for a total of 10 weeks (titration over 4 weeks, maintenance 6 weeks).
Placebo first
OTHERParticipants will take placebo three times daily for 10 weeks (titration over 4 weeks, maintenance 6 weeks). After a two week washout, participants will take acarbose three times daily for a total of 10 weeks (titration over 4 weeks, maintenance 6 weeks).
