Tandem Diabetes Care’s t:slim X2™ Insulin Pump is the First Automated Insulin Delivery System to Integrate with Abbott’s New FreeStyle Libre® 2 Plus Sensor

• Abbott’s latest innovation, the FreeStyle Libre^® 2 Plus sensor, is available for the first time for t:slim X2^™ insulin pump users in the U.S.
• Tandem’s Control-IQ^™ hybrid closed-loop technology now integrates with the first and only 15-day continuous glucose monitoring (CGM) sensor in the U.S.¹

Abbott (NYSE: ABT), the global health care company, and Tandem Diabetes Care, Inc. (NASDAQ: TNDM), a leading insulin delivery and diabetes technology company, today announced that the t:slim X2 insulin pump with Control-IQ technology is the first automated insulin delivery (AID) system to integrate with the newly available FreeStyle Libre 2 Plus sensor, Abbott’s latest continuous glucose monitoring (CGM) technology. For the first time, FreeStyle Libre technology users in the United States are now able to experience the therapeutic benefits of a hybrid closed-loop system that helps predict and prevent high and low blood sugar.

Tandem’s t:slim X2 insulin pump connects wirelessly to the FreeStyle Libre 2 Plus sensor, which sends automatic glucose readings every minute^2,3 to the pump. Users can conveniently see their minute-to-minute glucose data on the pump and accompanying t:connect mobile app.⁴ The pump’s Control-IQ technology predicts glucose levels 30 minutes into the future, automatically adjusting insulin delivery every five minutes based on CGM readings and can deliver automatic correction boluses (up to one per hour) to help prevent hyperglycemia.⁵ When left untreated, hyperglycemia can lead to long-term diabetes complications, such as nerve and kidney damage or disease of the eyes.

“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 chief executive officer 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’s latest addition to the FreeStyle Libre portfolio is the FreeStyle Libre 2 Plus sensor, which is the modified FreeStyle Libre 2 sensor cleared in 2023 by the U.S. Food & Drug Administration for use with AID systems. It is the first and only CGM available in the United States with a wear time of 15 days¹ for both adults and children. Demonstrating proven accuracy in overall glucose readings with an 8.2% MARD⁶, the sensor is small, discreet⁷ and comfortable⁸ to wear.

“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 accuracy⁶ that is simple, easy and affordable to use,” said Jared Watkin, executive vice president 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.”

Tandem will email instructions to all in-warranty t:slim X2 users in the U.S. offering the option to add the new FreeStyle Libre 2 Plus sensor integration at no cost via remote software update. t:slim X2 pumps pre-loaded with the updated software are now shipping to new customers. Information about the software update process for existing in-warranty pump users, including system requirements, is available at tandemdiabetes.com/softwareupdate.

The FreeStyle Libre 2 Plus sensor is available now at participating durable medical equipment (DME) suppliers. Please contact Abbott’s Customer Care Team at 1-844-330-5535 for a list of the participating DMEs.

2. FreeStyle Libre 2 Plus sensor connects via Bluetooth to the Tandem t:slim X2 insulin pump. Glucose data is visualized on the t:connect mobile app and t:slim X2 insulin pump.

3. Not applicable to insulin delivery adjustment frequency. Refer to Tandem t:slim X2 pump User Guide for specific details about how the Control-IQ technology algorithm adjusts insulin delivery.

4. The information on the t:connect mobile app display may not be identical to the current status of your pump. Wireless uploads from the t:connect mobile app to the cloud-based t:connect web application require a compatible phone and an internet or wireless data connection. Uploads to the t:connect web application do not take place in real time and should not be relied upon by healthcare providers or caregivers for remote patient monitoring. Standard carrier data rates may apply.

5. If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus using the Personal Profile settings and a target of 110 mg/dL and delivers 60% of that value.

Important Safety Information – FreeStyle Libre Systems

Failure to use FreeStyle Libre systems as instructed in labeling may result in missing a severe low or high glucose event and/or making a treatment decision, resulting in injury. If glucose reading and alarms (if enabled) do not match symptoms or expectations, use a fingerstick value from a blood glucose meter for treatment decisions. Seek medical attention when appropriate or contact Abbott at 855-632-8658 or freestyle.abbott/us-en/safety-information.html for safety info.

Responsible use of Control-IQ technology

Control-IQ technology does not prevent all highs and lows. Users must still bolus for meals and actively manage their diabetes. Visit tandemdiabetes.com/safetyinfo for additional important safety information.

Important Safety Information – t:slim X2 Insulin Pump

RX ONLY. The t:slim X2 pump and Control-IQ technology are intended for single patient use. The t:slim X2 pump and Control-IQ technology are indicated for use with NovoLog or Humalog U-100 insulin. t:slim X2 insulin pump: The t:slim X2 insulin pump with interoperable technology is intended for the subcutaneous delivery of insulin, at set and variable rates, for the management of diabetes mellitus in people 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 individuals 6 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 6 years of age and greater.

WARNING: Control-IQ technology should not be used by anyone under the age of 6 years old. It should also not be used in patients who require less than 10 units of insulin per day or who weigh less than 55 pounds.
