Tandem Diabetes Care Announces t:slim X2™ Insulin Pump Compatibility with Abbott's FreeStyle Libre® 3 Plus Sensor in the United States
Tandem continues to build its technology ecosystem to expand choice and personalization for people living with diabetes
Tandem Diabetes Care, Inc. (NASDAQ:TNDM), a leading insulin delivery and diabetes technology company today announced the Tandem t:slim X2™ insulin pump with Control-IQ+ automated insulin delivery (AID) technology now works with Abbott's FreeStyle Libre® 3 Plus continuous glucose monitoring (CGM) sensor. The Company has initiated an early access program in the United States (U.S.), and intends to scale availability in the second half of 2025.
"Diabetes management is not one-size-fits-all and it is critical for people living with diabetes to be able to personalize their AID systems to fit their unique healthcare and lifestyle needs," said Dr. Jordan Pinsker, chief medical officer of Tandem Diabetes Care. "The American Diabetes Association recommends AID systems as the preferred insulin delivery method in people with type 1 and other types of insulin-deficient diabetes, and this integration with Abbott's latest generation sensor allows even more CGM users to access the life-changing benefits of our Control-IQ+ technology."
The FreeStyle Libre 3 Plus sensor has an extended 15-day wear time, transmitting automatic glucose readings every minute directly to the pump. This data is also available to view on the Tandem t:slim mobile app, providing users with multiple, convenient ways to access their current glucose trend.
The t:slim X2 insulin pump is powered by Control-IQ+ technology, the latest generation of Tandem's advanced hybrid closed-loop algorithm, which adjusts insulin every 5 minutes based on predicted glucose values. It's the only system with the unique AutoBolus™ feature that calculates and delivers a correction bolus to help with missed meal boluses.* Control-IQ+ is easy to start, use, and personalize, and this latest integration works with the FreeStyle Libre 3 Plus sensor and extends its benefits to even more people with diabetes.
"This is an exciting first step in our strategy to connect Tandem's portfolio of insulin pumps to Abbott's FreeStyle Libre 3 Plus sensors worldwide," said John Sheridan, president and chief executive officer of Tandem Diabetes Care. "We look forward to expanding access to our t:slim X2 users outside of the U.S. beginning later this year."
When available, Tandem will email eligible users in the U.S. with more information.†

Important Safety Information – Tandem Diabetes Care
RX ONLY. The t:slim X2 pump with interoperable technology (the pump) and Control-IQ+ technology (Control-IQ+) are intended for single patient use. The pump and Control-IQ+ are indicated for use with NovoLog or Humalog U-100 insulin. t:slim X2 insulin pump: The pump is intended for the subcutaneous delivery of insulin, at set and variable rates, for the management of diabetes mellitus in persons requiring insulin. The pump is able to reliably and securely communicate with compatible, digitally connected devices, including automated insulin dosing software, to receive, execute, and confirm commands from these devices. The pump is indicated for use in persons 2 years of age and greater. Control-IQ+ technology: Control-IQ+ technology is intended for use with compatible integrated continuous glucose monitors (iCGM, sold separately) and alternate controller enabled (ACE) pumps to automatically increase, decrease, and suspend delivery of basal insulin based on iCGM readings and predicted glucose values. It can also deliver correction boluses when the glucose value is predicted to exceed a predefined threshold. Control-IQ+ technology is intended for the management of Type 1 diabetes mellitus in persons 2 years of age and greater and of Type 2 diabetes mellitus in persons 18 years of age and greater.
WARNING: Control-IQ+ should not be used in anyone under the age of 2 years old with Type 1 diabetes or under the age of 18 years old with Type 2 diabetes. It should also not be used in patients who require less than a total daily insulin dose of 5 units of insulin per day or who weigh less than 20 pounds (9 kilograms), as those are the required minimum values needed for Control-IQ+ to operate safely.
Users of the pump and Control-IQ+ must: use the insulin pump, iCGM, and all other system components in accordance with their respective instructions for use. Failure to follow these instructions for use could result in an over delivery or under delivery of insulin. This can cause hypoglycemia (low BG) or hyperglycemia (high BG) events.
