The battle to claim the continuous glucose monitor with the longest wear time continues with Dexcom Inc.’s G7 15 Day continuous glucose monitor gaining U.S. FDA clearance on April 10 for adults with diabetes. The company said it now takes the lead with the 15-day duration, but Abbott Laboratories also offers 15 days of useful life for its Freestyle Libre 3 plus.

For people with type 1 or type 2 diabetes and the companies developing technologies to help them, the International Conference on Advanced Technologies & Treatments for Diabetes delivered an abundance of good news. On the type 1 diabetes front, Insulet Corp.’s RADIANT study demonstrated massive improvement in time in range as well as lower glycemic levels for patients switching from multiple injections to the Omnipod 5 automated insulin delivery system.
