This marks the first automated insulin delivery system to integrate the newly available Abbott FreeStyle Libre 2 Plus sensor. The FDA cleared the updated Abbott continuous glucose monitor (CGM) for use with automated insulin delivery in March 2023. For the first time, users of the leading CGM sensor can utilize a hybrid closed-loop system to manage their diabetes.
Integration of these technologies comes shortly after Tandem became the first to integrate with the next-generation Dexcom G7 CGM. The t:slim X2 insulin pump with Control-IQ technology previously worked with the Dexcom G6.
Tandem’s automated insulin delivery system now connects wirelessly to the FreeStyle Libre 2 Plus. The sensor sends automatic glucose readings every minute to the pump. Users can see their minute-to-minute glucose data on the pump and accompanying t:connect mobile app.
Control-IQ technology predicts glucose levels every 30 minutes into the future. It automatically adjusts insulin delivery every five minutes based on CGM readings. The technology can also deliver automatic correction boluses (up to one per hour) to help prevent hyperglycemia.
“Tandem’s leadership in AID innovation is underscored with this milestone of launching the first insulin pump to be compatible with Abbott’s CGM technology in the U.S.,” said John Sheridan, president and CEO of Tandem Diabetes Care. “This represents another step forward in our commitment to provide customizable solutions to help reduce burden and create new possibilities for people living with diabetes.”

Abbott modified the original FreeStyle Libre 2 for the purpose of integration with automated insulin delivery systems. The company says it’s the first and only CGM available in the U.S. with a wear time of 15 days for both adults and children.
FreeStyle Libre 2 Plus offers a MARD (a measure of accuracy in CGMs) of 8.2%. The small, discreet sensor also offers comfortability, according to the company.
Tandem plans to email instructions to all in-warranty t:slim X2 users in the U.S. The company intends to offer the option to add the new CGM integration at no cost through a remote software update. It already began shipping t:slim X2 pumps pre-loaded with updated software to new customers.
“Our FreeStyle Libre portfolio empowers people living with diabetes to have more control over their health and eases the burden of their condition by using a continuous glucose monitoring system with unsurpassed accuracy6that is simple, easy and affordable to use,” said Jared Watkin, EVP of Abbott’s diabetes care business. “Through the integration of Tandem’s t:slim X2 insulin pump with our FreeStyle Libre 2 Plus sensor, people only need two sensors a month, which ensures both a more convenient and more affordable experience.”
