Senseonics Holdings, Inc. has announced the FDA approval of its Eversense E3 CGM System. The company currently offers a 90-day capable continuous glucose monitor (CGM) but the Eversense E3 system will double that amount to 180 days. In addition, fewer fingerstick blood glucose measurements will be required.

People with diabetes who use a CGM system will be interested to learn about the FDA approval of Senseonics’ Eversense E3 unit. The firm already has the Eversense 90-Day CGM System and has taken a considerable leap forward with the third-generation E3 iteration. Not only will the latter system last for up to 6 months without needing to be replaced but after an initial probation period of 21 days users will also only require a single fingerstick blood glucose (BG) measurement for the purpose of calibration per day. The current Eversense CGM system requires two fingersticks just for daily calibration.  

The Eversense E3 CGM system comprises of a sensor, a transmitter, and a mobile app. The sensor is inserted under a patient’s skin usually on the upper arm in a swift procedure, and it relies on “sacrificial boronic acid (SBA) technology” to offer precise blood glucose readings over the 180-day period. The transmitter, which vibrates to alert the user to “high and low glucose excursions” (hypo or hyperglycemic events), is positioned over the area where the sensor has been inserted and uses a silicone adhesive to stay in place. It is water resistant, and it can be easily removed and replaced as required.

The company expects the Eversense E3 6-month CGM system to become available to the public at the start of the second quarter of 2022. No specific cost is detailed for the upcoming glucose monitor; however, the 90-day model is believed to cost around US$533 per month or US$6,400 a year and the E3 unit is likely to be priced at a similar scale. Insurance coverage is available, and the Eversense E3 will be made available to people who have been diagnosed with diabetes for at least six months and are aged 18 or over.

Senseonics Announces FDA Approval of the Eversense® E3 Continuous Glucose Monitoring System for Use for Up to 6 months; Provides 2022 Business Outlook

The world’s first and only long-term implantable CGM system now offers patients exceptional accuracy for 6 months

<time itemprop="dateModified" datetime="2022-02-11T12:00:00Z">February 11, 2022 07:00 AM Eastern Standard Time</time>

GERMANTOWN, Md.--()--Senseonics Holdings, Inc. (NYSE American: SENS), a medical technology company focused on the development and manufacturing of long-term, implantable continuous glucose monitoring (CGM) systems for people with diabetes, today announced the approval of the next-generation Eversense® E3 CGM System by the Food and Drug Administration (FDA). The Eversense E3, including proprietary sacrificial boronic acid (SBA) technology to extend longevity to 6 months, is planned to be available to patients in the U.S. through Ascensia Diabetes Care, Senseonics’ global commercial partner, beginning in the second quarter of 2022.

“The Eversense E3 CGM System is an exciting advancement in diabetes management”

“We repeatedly hear from our patients with diabetes that what they desire is a long-lasting sensor that is also highly accurate,” said Satish Garg, M.D., Professor of Medicine and Director of the Adult Diabetes Program at the Barbara Davis Center of the University of Colorado, and the Principal Investigator of the PROMISE Study1, which formed the basis for the FDA approval. “The next generation Eversense E3 System delivers on both. Patients will appreciate the excellent accuracy of the system and the ability of the sensor to last 6 months. This is another step forward for patients who desire to manage their diabetes with all the advantages of the Eversense CGM with the fully implantable sensor.”

The Eversense E3 CGM System offers patients:

  • Fully implantable third generation sensor, with proprietary SBA technology to enhance sensor longevity, demonstrating a mean absolute relative difference (MARD) of 8.5% in the PROMISE Study.
  • Industry leading 6 month sensor wear duration, making Eversense the longest lasting CGM system available, with essentially two sensor insertion and removal procedures per year.
  • Removable smart transmitter, held in place with a mild silicone-based adhesive, providing discreet on-body vibratory alerts and data transmission to a mobile app where glucose values, trends, and alerts are displayed.

“Further extending the duration of the longest lasting CGM system to 6 months represents a massive leap forward for patients and towards our mission of transforming lives in the global diabetes community,” said Tim Goodnow, PhD, President and Chief Executive Officer of Senseonics. “The review was delayed by one year due to COVID-19 priorities and now together with our partner Ascensia, we can execute our launch plan to deliver the Eversense E3 CGM System to U.S. patients beginning in the second quarter. We look forward to initiating Eversense E3 sales and believe that, with Ascensia’s newly dedicated CGM commercial organization, the launch of the new 6-month product will establish the foundation for growth in our installed base later in 2022 and beyond.”

After the extended review during COVID-19, and with its next generation product now having been approved in the U.S., the Company concurrently is providing its 2022 financial outlook. The Company expects full year 2022 global net revenue to be in the range of $14.0 million to $18.0 million. The Company expects the majority of its expenses for 2022 to be for research and development for ongoing feasibility and pivotal clinical trials for additional products in its product pipeline, including the start of its 365-day pivotal trial, subject to IDE approval. Additionally, the Company currently expects to report unaudited revenues of approximately $4.0 million for the fourth quarter of 2021 and approximately $13.7 million for the full year ended December 31, 2021. The unaudited balance of cash, cash equivalents and marketable securities at December 31, 2021 was approximately $182 million. The Company expects to report its full fourth quarter and fiscal year 2021 financial results after the market close on Tuesday, March 1, 2022. The preliminary financial results described herein have not been audited and are subject to adjustment based on the Company’s completion of year-end financial close processes.

“The Eversense E3 CGM System is an exciting advancement in diabetes management,” said Francine Kaufman, M.D., Chief Medical Officer of Senseonics. “We believe patients and providers are waiting for this step forward. I want to take this opportunity to thank the PROMISE Study investigators, study participants, and the Senseonics team for helping us reach this important milestone, and the diligence of the FDA reviewers in this difficult environment. We are excited to begin making this next generation product available in the U.S. to people with diabetes.”

The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are still required for calibration 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 trained and certified 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
