Senseonics Publishes Positive Longitudinal Performance Over Multiple Sensor Insertions and Removal Cycles of the Eversense® CGM System

November 21, 2019 GMT

GERMANTOWN, Md.--(BUSINESS WIRE)--Nov 21, 2019--

Senseonics Holdings, Inc. (NYSE American: SENS) 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.

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.

About Eversense

The Eversense ® Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels in persons age 18 and older with diabetes for up to 90 days. The system will be used to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements will still be required for calibration twice per day, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense CGM System is a prescription device; patients should talk to their health care provider to learn more. For important safety information, see https://eversensediabetes.com/safety-info/.

About Senseonics

Senseonics Holdings, Inc. is a medical technology company focused on the design, development and commercialization of transformational glucose monitoring products designed to help people with diabetes confidently live their lives with ease. Senseonics’ CGM Systems, Eversense ® and Eversense ® XL, include a small sensor inserted completely under the skin that communicates with a smart transmitter worn over the sensor. The glucose data are automatically sent every 5 minutes to a mobile app on the user’s smartphone.
