About

This is a prospective, single arm, open-label, interventional, pilot study to evaluate the accuracy and precision of the continuous glucose monitoring (CGM) system of i-SENS, Inc., CareSens Air 3, in adult patients with type 1 diabetes.

Full description

Participants will wear two CareSens Air 3 and one Libre 3 Plus for 16 days without access to glucose values from the CareSens Air 3 devices while maintaining their original diabetes mellitus treatment. The participants will draw capillary blood at least 8 times a day using the SMBG system between study visits.

Between insertion and removal of the CareSens Air 3 the participants will be in the clinic 4 times to obtain accurate glucose reading from the reference device under carefully controlled circumstances including induction of low and high blood glucose.
