“We are very pleased that we received a prompt approval to extend the study to gather valuable data,” said Tim Goodnow, Ph.D., President, and CEO of Senseonics. “The scientific, clinical and technical data we will obtain will be critical to further extend sensor longevity. We’re very grateful to the FDA for the green light, for the tireless clinical investigators, and particularly, to the devoted study participants for giving us this opportunity.”
The goal of the PROMISE Clinical Study is to evaluate the safety and efficacy of the Eversense CGM System in people with diabetes over a 180-day period for the pre-market application submission to the U.S. Food and Drug Administration. One hundred and eighty-one (181) study participants at 8 sites across the United States had the Eversense CGM System inserted subcutaneously as part of the study, which is completing the 180-day duration in March. Now, a sub-set of more than 35 participants who all had a sensor with the modified chemistry will be left undisturbed for 365 days with the goal of measuring accuracy and longevity over the full 365 days.
“Extending this study is really a critical step in developing a 365-day product. Information gathered from this cohort will allow us to characterize the improved sensor design and optimize our glucose algorithm for the extended, 365-day use period,” explained Mukul Jain, Ph.D., Chief Operating Officer at Senseonics. “This addition is an exciting extension phase of the PROMISE study and we look forward to evaluating the first multi-clinic investigation of a one-year implantable glucose sensor.”
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. Eversense users now have the freedom to make treatment decisions based on their Eversense readings. The sensor is inserted subcutaneously in the upper arm by a health care provider via a brief in-office procedure.
