FOR IMMEDIATE RELEASE
Tandem Diabetes Care Announces FDA Clearance of the t:slim X2 Insulin Pump with
Control-IQ Advanced Hybrid Closed-Loop Technology
Automated Insulin Dosing Software First to Receive New Classification by FDA
San Diego, CA - December 13, 2019 - Tandem Diabetes Care, Inc. (NASDAQ: TNDM), a leading insulin delivery and diabetes technology company, today announced U.S. Food and Drug Administration (FDA) clearance of the t:slim X2™ insulin pump with Control-IQ™ technology, an advanced hybrid-closed loop feature designed to help increase time in range (70-180 mg/dL)1, and the first system cleared to deliver automatic correction boluses in addition to adjusting insulin to help prevent high and low blood sugar. The system integrates with Dexcom G6 continuous glucose monitoring (CGM), which requires no fingersticks for calibration or diabetes treatment decisions.2,3,4 Control-IQ technology for the t:slim X2 insulin pump is the first automated insulin dosing software in a new interoperable automated glycemic controller category that automatically adjusts insulin delivery to a person with diabetes by connecting to an alternate controller-enabled insulin pump (ACE pump) and integrated continuous glucose monitor (iCGM). This is the third category classified by the FDA for the interoperability of devices as a complete automated insulin dosing (AID) system.
All in-warranty t:slim X2 pump users in the United States will have the option to add the new feature free of charge via remote software update.5 The update is expected to be available by the end of January 2020, and new pumps with Control-IQ technology will begin shipping to customers in the same timeframe. The Company will continue to offer the t:slim X2 pump with Basal-IQ® predictive low glucose suspend technology as an option for people who prefer a system designed specifically to help prevent lows.
The t:slim X2 insulin pump with Control-IQ technology uses CGM values, in conjunction with other variables such as insulin on board, to predict glucose levels 30 minutes ahead and adjust insulin delivery accordingly. If glucose values are predicted to drop below 112.5 mg/dL, basal insulin delivery is reduced, and when predicted to be below 70 mg/dL, basal insulin delivery is stopped. If glucose values are predicted to be above 160 mg/dL in the next 30 minutes, basal insulin will be increased. If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus with a target of 110 mg/dL, and delivers 60 percent of that value up to once an hour as needed. Control-IQ technology also offers optional settings for sleep and exercise that will change the treatment values to better match the different physiologic needs during these activities.
With the interoperable automated glycemic controller designation, the FDA establishes a new device class which includes special controls outlining requirements for this and future submissions in this category, as well as describes the reliability, device interoperability, cybersecurity, and clinical relevance data required to demonstrate acceptable performance. The t:slim X2 insulin pump was also the first to receive an ACE infusion pump classification in February 2019, and the first insulin pump designated as compatible with iCGM devices in June 2018.

“Not only do new closed-loop systems need to be effective at improving glycemic control, they must also be easy to understand and use so patients can experience the full benefits of the technology. The t:slim X2 insulin pump with Control-IQ technology successfully achieved both objectives in the clinical studies,” said Boris Kovatchev, PhD, Director of the Center for Diabetes Technology at the University of Virginia and principal investigator of the International Diabetes Closed Loop (iDCL) trials. “We are very proud of the extensive academic research that went into this effort, and we are thrilled to see this work has translated into an FDA-cleared device for clinical use so that more people can experience the benefits of this technology.”
“With this clearance, we will be launching the most advanced automated insulin dosing system commercially available in the world today,” said John Sheridan, president and CEO of Tandem Diabetes Care. “This is a testament to our commitment to improving the lives of people with diabetes by offering simple-to-use products that deliver superior performance.”
“The approval of the Control-IQ system with Dexcom G6 CGM brings together two incredible products to deliver a powerful automated insulin dosing solution for people with diabetes,” said Kevin Sayer, president and CEO of Dexcom. “Sensor accuracy is a critical component for automated insulin dosing, and we are excited that Dexcom G6 users can benefit from our collaborative effort to integrate this advanced hybrid closed loop system.”
Benefits of Control-IQ Advanced Hybrid Closed-Loop Technology:
Predicts and helps prevent lows and highs - Control-IQ technology uses CGM readings to predict glucose values 30 minutes ahead and can increase, decrease or stop basal insulin delivery to help keep glucose in range (70-180 mg/dL).1
Automatic Correction Boluses - If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus with a target of 110 mg/dL and delivers 60 percent of that value. It will do this up to once an hour as needed.
Accommodates for sleep and exercise - Control-IQ technology offers optional settings for sleep and exercise that change the treatment values to better match the different physiologic needs during these activities.
No fingersticks - With Dexcom G6 CGM integration, the Control-IQ feature works with no fingersticks required for mealtime dosing or calibration.2 Other benefits of the Dexcom G6 CGM include an extended 10-day wear, acetaminophen blocking6 ,and the ability to share real-time CGM data with up to 10 followers.7
Easy to use - The system has no complicated criteria to keep Control-IQ technology on. If the CGM signal is temporarily lost, the Control-IQ feature will resume automatically when the CGM is back in range. In the pivotal study, participants gave Control-IQ technology a 4.7 out of 5.0 for ease of use, and a 4.8 out of 5.0 for desire to continue use of the system.8
Standard Features of the t:slim X2 Insulin Pump:
Color touchscreen - The large color touchscreen on the t:slim X2 pump is easy to read, simple to learn, and intuitive to use for anyone familiar with a smartphone or tablet.
Small and discreet - The t:slim X2 pump is up to 38 percent smaller than other pumps9, yet can hold up to 300-units of insulin.
Can be used with or without the Control-IQ feature or CGM - When advanced features are turned off, the t:slim X2 pump removes the CGM chart from the screen and puts the Bolus and Option buttons front and center for easy access.
#1-rated customer support - Tandem Diabetes Care customer support has been consistently ranked number one by pump users in independent patient surveys since 2013.10

Control-IQ Technology - Clinical Outcomes
Data from the NIH-funded DCLP3 study, published by the New England Journal of Medicine in October 2019, compared use of a t:slim X2 insulin pump with Control-IQ technology and Dexcom G6 CGM integration (n=112) to a control group using a t:slim X2 pump with just Dexcom G6 CGM integration (n=56).8 This study was the first large-scale 6-month closed loop study to include a dedicated control group. There were no exclusion criteria based on hemoglobin A1c, history of acute complications, or previous experience using an insulin pump, and all participants completed the study. Those using Control-IQ technology experienced 71 percent time in range (70-180 mg/dL) per day on average compared to 59 percent in the control group.1 Sensor time spent above 180 mg/dL was 27 percent per day on average with Control-IQ technology and 39 percent in the control group. Sensor time spent below 70 mg/dL was 1.4 percent per day on average with Control-IQ technology and 1.9 percent in the control group. The system remained connected to CGM with Control-IQ on and active an average of 92 percent of the 26-week study period. In a five-point survey at the end of the study, users overwhelmingly rated the Control-IQ system as simple to use, giving it a 4.5 for trust, a 4.7 for ease of use, and a 4.8 for desire to continue using the system.
