Tandem Diabetes Care, Inc. (NASDAQ: TNDM), a leading insulin delivery and diabetes technology company, today announced Health Canada approval of the t:slim X2™ insulin pump with Control-IQ™ technology. Control-IQ technology is an advanced hybrid closed-loop feature designed to help increase time in range (3.9-10 mmol/L)1 and 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

All in-warranty t:slim X2 pump users in Canada will have the option to add Control-IQ technology to their existing pump beginning in March 2021 via remote software update. The update will be free of charge through December 31, 2021.5 Tandem expects to begin shipping t:slim X2 insulin pumps with Control-IQ technology in Canada in the first quarter of next year. The company will continue offering the t:slim X2 insulin pump with Basal-IQ™ predictive low glucose suspend technology for users seeking a system designed specifically to help prevent lows.

“The t:slim X2 insulin pump with Control-IQ technology is the most advanced automated insulin dosing system available in the world and is a testament to our commitment to improving the lives of people with diabetes,” said John Sheridan, president and CEO of Tandem Diabetes Care. “We are thrilled to be able to bring the benefits of this advanced hybrid closed-loop system to the Canadian diabetes community.”

Control-IQ technology uses Dexcom G6 CGM values to predict glucose levels 30 minutes ahead and adjust insulin delivery accordingly; including delivery of automatic correction boluses up to once per hour. If sensor glucose values are predicted to drop below 6.25 mmol/L, basal insulin delivery is reduced, and when predicted to be below 3.9 mmol/L, basal insulin delivery is stopped. If glucose values are predicted to be above 8.9 mmol/L, basal insulin delivery will be increased. If glucose values are predicted to be above 10 mmol/L, Control-IQ technology calculates an automatic correction bolus with a target of 6.1 mmol/L and delivers 60 percent of that value. It will do this up to once per 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.

Benefits of Control-IQ Advanced Hybrid Closed-Loop Technology

Predicts and helps prevent highs and lows – 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 (3.9-10 mmol/L).1

Automatic Correction Boluses – If glucose values are predicted to be above 10 mmol/L, Control-IQ technology calculates a correction bolus with a target of 6.1 mmol/L 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 blocking,6 and the ability to share real-time CGM data with up to 5 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

Colour touchscreen – The large colour 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 pumps,9 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.

Free Software Update for Current t:slim X2 Pump Users

All in-warranty t:slim X2 pump users in Canada will have the option to add the Control-IQ feature free of charge through December 31, 2021 via a software update using a personal computer. Current in-warranty t:slim X2 pump users in Canada will receive emails with more information about the process, including a link to a 30 to 45-minute online training module which must be completed prior to updating their pump. Internet and computer access are required for pump updates. Tandem Diabetes Care expects the Control-IQ technology software update to be available for current t:slim X2 pump users in March 2021.

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).6 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 (3.9-10 mmol/L) on average compared to 59 percent in the control group.1 Sensor time spent above 10 mmol/L was 27 percent per day on average with Control-IQ technology and 39 percent in the control group. Sensor time spent below 3.9 mmol/L 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 technology 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.8

Responsible Use of Predictive Technologies

Even with advanced systems such as the t:slim X2 insulin pump with Control-IQ technology, users are still responsible for actively managing their diabetes. Control-IQ technology does not prevent all high and low blood glucose events. The system is designed to help reduce glucose variability, but it requires accurate input of information, such as meals and periods of sleep or exercise. Control-IQ technology will not function as intended unless all system components are used as instructed, including CGM, infusion sets, and pump cartridges. Importantly, the system cannot adjust insulin dosing if the pump is not receiving CGM readings. Since there are situations and emergencies that the system may not be capable of identifying or addressing, users must always pay attention to symptoms and treat according to their healthcare provider’s recommendations.

Important Safety Information

The t:slim X2 insulin pump and the t:slim X2 insulin pump with Control-IQ technology are intended for single patient use. The t:slim X2 pump and the t:slim X2 pump with Control-IQ technology are indicated for use with NovoRapid or Humalog U-100 insulin.
