NCT ID NCT05806554
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed trial tested how accurately the True Vie I3 continuous glucose monitor measures blood sugar levels in 159 adults with type 1 or type 2 diabetes. Participants wore the device while researchers compared its readings to standard lab measurements. The goal was to see if the device meets FDA accuracy standards for integrated continuous glucose monitors.
