FDA Clears New Dexcom G7 15 Day Continuous Glucose Monitoring System
Pharmacists have positive impacts on health outcomes for diabetes and patients using CGM devices, including reductions in A1c.
The FDA cleared the new Dexcom G7 15 Day Continuous Glucose Monitoring (CGM) System for patients 18 years and older with diabetes. The device builds on the performance of other Dexcom CGMs and has an overall mean absolute relative difference (MARD) of 8%, which increases the accuracy over other CGMs.1
“The approval of Dexcom G7 15 Day marks another major innovation for Dexcom,” Jake Leach, executive vice president and chief operating officer at Dexcom, said in a news release.1 “By listening to the needs of our users, we’re proud to offer the longest lasting wearable and most accurate CGM, giving people the knowledge to better control their diabetes with our best-in-class technology. This milestone sets a new standard in CGM and is a testament to our continued leadership in glucose biosensing.”
The newly cleared device lasts approximately 15.5 days of wear and includes features from the Dexcom G7, which include sensors connecting to an Apple Watch, is waterproof, has a 12-hour grace period to replace finished sensors, and has the ability to share data with caregivers.1
“Dexcom G7 15 Day makes managing diabetes even easier with its extended wear and greater accuracy,” Satish Garg, MD, from the Barbara Davis Center for Diabetes at the University of Colorado School of Medicine, said in a news release.1 “Data recently released during the 18th International Advanced Technologies and Treatments for Diabetes conference in Amsterdam supports that G7 15 Day is the most accurate CGM for adults.”
