Amish volunteers help unlock genetic secrets of diabetes drug
NCT ID NCT02891954
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a person's genes can predict how their body responds to canagliflozin, a drug used for type 2 diabetes. About 700 healthy Amish adults will take the drug for five days, and researchers will measure changes in urine sugar and other markers. The goal is to find genetic variations that could help personalize diabetes treatment in the future.
