This trial is active, not recruiting.
|Treatments||dietary: saccharin, estimate glucose absorptions|
|Sponsor||Translational Research Institute for Metabolism and Diabetes, Florida|
|Collaborator||Sanford-Burnham Medical Research Institute|
|Start date||August 2014|
|End date||January 2017|
|Trial size||20 participants|
|Trial identifier||NCT02835859, TRIMD FH 607060|
The purpose of this study is to collect data that will help researchers better understand the various causes of obesity and diabetes; particularly to understand how consumption of NCASs affects the way the body uses nutrients.
|Endpoint classification||pharmacokinetics study|
|Intervention model||single group assignment|
