The PRECISE II (U.S.) Trial¹
The second study (PRECISE II), performed in the United States, investigated the efficacy and safety of the Eversense CGM System during 90 days of continuous sensor wear. A total of 90 adults with Type 1 or Type 2 diabetes at 8 clinical centers were enrolled. Accuracy and safety endpoints were similar to those in the previous PRECISE study. This study also included an exercise session and durations of sensor compression.
Overall MARD value was 8.5%* (95% confidence interval: 8.1-9.3%). 91% percent of sensors were functional through day 90. Accuracy was not impacted by exercise or sensor compression. No infections or adhesive skin reactions were reported, and one related serious adverse event (1.1%) occurred during removal of a sensor.
The Eversense System detected 90% of hypoglycemic excursions detected (70mg/dL) and 98% of hyperglycemic excursions detected (180mg/dL).

*The MARD demonstrated in the PRECISE II study was 8.8% using the study software. The algorithm that calculates glucose values was updated after the completion of the PRECISE II study. When the updated “Software 602” algorithm was applied to the raw sensor data of the PRECISE II study, the primary endpoint was met with a demonstrated MARD of 8.5%.
The advanced sensor technology and under-the-skin sensor help patients reach unprecedented levels of wear time, leading to improved clinical outcomes.
