Senseonics has published the assessment of performance of multiple sequential cycles of Eversense 90 and 180-day CGM System use in the peer reviewed scientific journal Diabetes Technology and Therapeutics
Senseonics Holdings, a medical technology company focused on the development and commercialization of the first and only long-term, implantable continuous glucose monitoring (CGM) system for people with diabetes, announced the publication of an assessment of the performance of multiple sequential cycles of Eversense 90 and 180-day CGM System use in the peer reviewed scientific journal Diabetes Technology and Therapeutics. This real-world data of 945 adult users in the home-setting demonstrated that the performance of the sensor over four sensor cycles is stable and does not decrease over time. In addition, there was no degradation of patient glucose outcomes over the four sensor cycles.
“Our extensive real-world data shows that almost 1,000 Eversense users stayed in the target glucose range for 63-64%1 of the time, while other recent clinical studies show that patients using a sensor and pump only stayed in the target glucose range for 59%2 of the time. The Eversense real-world data demonstrates the difference an accurate, long-term CGM sensor can make when it is worn more than 80% of the time,” explained Francine R. Kaufman, MD, Endocrinologist, Chief Medical Officer and Board Member at Senseonics. “A significant proportion of Eversense users are also choosing to have a new sensor implanted at the end of each sensor cycle. This large real-world data set supports the clinical relevance and accuracy of the Eversense system to the healthcare provider and payer communities as we seek further expansion of coverage for Eversense as a clinically-proven choice for CGM therapy.”
For this study, the Eversense Data Management System (DMS) was evaluated for accuracy by comparing sensor glucose values (SG) with self-monitored blood glucose values (SMBG) during the time period from June 2016 through August 2019 in Eversense users in Europe and South Africa who had gone through at least four sensor cycles.
REAL-WORLD CLINICAL PERFORMANCE SUMMARY
Time in Range – 63-64% of time spent between 70-180 mg/dL demonstrating promising and durable time in range throughout multiple sensor wear cycles
Estimated A1c* – 7.0-7.1 over 4 sensor cycles demonstrating sustained real-world glycemic control
Wear Time – 83.2% to 85.8% median wear time across all 4 sensor cycles confirming patient adherence to the device over a multi-cycle wear periods including almost 1300 patient-years of real-world follow-up.
Sustained Excellent performance – demonstrating sustained accuracy from sensor 1 through sensor 4 with no deterioration over time. These data show the ability of Eversense to consistently perform over multiple cycles of sensor wear for up to 2 years duration.

The Eversense CGM System consists of a fluorescence-based sensor, a smart transmitter worn over the sensor to facilitate data communication, and a mobile app for displaying glucose values, trends and alerts. In addition to featuring the first long-term and first implantable CGM sensor, the system is also first to feature a smart transmitter that provides wearers with discreet on-body vibratory alerts when high or low glucose thresholds are crossed and can be removed, recharged and re-adhered without discarding the sensor. The sensor is inserted subcutaneously in the upper arm by a health care provider via a brief in-office procedure.
