Tandem Diabetes Care Gets FDA Ok For t:slim X2 Insulin Pump with Control-IQ Technology

Tandem Diabetes Care, Inc. received U.S. Food and Drug Administration (FDA) clearance of the t:slim X2™ insulin pump with Control-IQ™ technology last week.

The system features an advanced hybrid-closed loop 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.

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.

What About Existing t:slim X2 Pump Users?

All in-warranty t:slim X2 pump users in the U.S. will have the option to add the new feature free of charge via remote software update.

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.

Tandem 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.

How Does the Pump Work?

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, the 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.

What Does the Designation Mean?

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.

More information on the new interoperable automated glycemic controller classification can be found in the press release issued by the FDA.

“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,” said Dr. Boris Kovatchev, director of the Center for Diabetes Technology at the University of Virginia and principal investigator of the International Diabetes Closed Loop (iDCL) trials. “The t:slim X2 insulin pump with Control-IQ technology successfully achieved both objectives in the clinical studies,”

With this clearance, John Sheridan, president, and CEO of Tandem Diabetes Care said the company will be launching the most advanced automated insulin dosing system commercially available in the world.

“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,” he said.
