Senseonics Announces First Study Participant Implanted in the U.S. as Part of the PROMISE 180-Day Sensor Clinical Study and the Submission of Key PMA Supplements to the FDA to Advance Current 90-Day Product

GERMANTOWN, Md.--(BUSINESS WIRE)-- Senseonics Holdings, Inc. (NYSE-American: SENS), a medical technology company focused on the development and commercialization of a long-term, implantable continuous glucose monitoring (CGM) system for people with diabetes, today announced that the extended life Eversense® XL sensor that lasts up to 180 days has been implanted in the first U.S. study participant as part of the clinical trial for pre-market application submission to the Food and Drug Administration.

The PROMISE Clinical Study is intended to evaluate the safety and efficacy of the Eversense CGM system in people with diabetes over a 180-day period. Approximately 180 study participants at up to 15 locations across the United States are planned to enroll in the study. The Eversense XL sensor previously received the CE Mark and is currently marketed to patients across the European Union.

Senseonics also announced that the company has completed its submission of PMA supplements to the FDA to secure an insulin dosing claim and to remove the contraindication related to the Magnetic Resonance Imaging (MRI) exposure on the 90-day system which is currently available in the United States.

“I am thrilled to be able to offer a long term implantable sensor to my patients through the PROMISE 180-day Clinical Study,” said Dr. Mark Christiansen, Co-Medical Director of Diablo Clinical Research and the first physician to insert the extended life long-term sensor. “We are looking forward to providing patients six months of continuous sensing and the potential benefits of a long-term sensor.”

“We are pleased to have enrolled the first participant in this important study which demonstrates our continued progress in transforming CGM technology. This is the first study in the US in which participants are implanted with a single sensor designed to produce accurate continuous glucose measurements for half of a year,” said Tim Goodnow, President and Chief Executive Officer. “Our submission of the Supplements to secure the dosing claim and to remove the MRI contraindication for the current 90-Day Eversense system are significant step forward in reducing the burden of diabetes management and providing patients peace of mind.”
