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, today announced further presentation of PROMISE Study data evaluating the next generation Eversense CGM System at the American Diabetes Association Virtual 81^st Annual Scientific Sessions.

The data evaluating the safety and accuracy of the next generation Eversense system was presented by Satish Garg, MD, Professor of Medicine at the Barbara Davis Center of the University of Colorado, Denver, and the PROMISE study group Principal Investigator (PI). The Company presented previously released information demonstrating performance matching that of the current 90-day sensor available in the United States, with reduced calibration, down to one per day, with duration extended to 180 days. Accuracy measurements discussed in the oral presentation include a mean absolute relative difference (MARD) of 9.1% for the primary sensor and confirmed hypoglycemia alert detection rates at 60 mg/dL of 87% and at 70 mg/dL of 93%. For the subset of 43 modified sensors (referred to as the SBA sensor), the MARD was 8.5% and the confirmed hypo alert detection rates at 60 mg/dL and 70 mg/dL were 90% and 94%, respectively.

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 for high and low glucose and can be removed, recharged and re-attached to the skin without discarding the sensor.

More information on the Eversense system is available at www.eversensediabetes.com and physicians, nurse practitioners or physician assistants interested in learning more about the Eversense CGM System for their patients can contact 844-SENSE4U (844-736-7348).

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 is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions in the US. Fingerstick BG measurements are still 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/.
