Can a smart sensor beat finger sticks for diabetes control?
NCT ID NCT05944432
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This study compares continuous glucose monitoring using the FreeStyle Libre 3 sensor to standard finger-stick testing in 470 adults with type 2 diabetes whose blood sugar is not well controlled. Participants continue their usual medications (basal insulin plus SGLT2 inhibitor and/or GLP-1). The main goal is to see if the sensor improves HbA1c levels over 16 weeks. This is a management study, not a cure, as diabetes requires ongoing care.
