News Release

SAN DIEGO--(BUSINESS WIRE)--Jun. 17, 2020-- 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 an expanded pediatric indication for the t:slim X2™ insulin pump with Control-IQ™ technology to children age six and older. The product was previously approved for ages 14 and older. Control-IQ technology is an advanced hybrid closed-loop feature designed to increase time in range (70-180 mg/dL).¹

Control-IQ technology helps simplify diabetes management for younger patients by adjusting insulin delivery to help prevent highs and lows, automatically delivering correction boluses up to once per hour, and offering exercise and sleep-specific features. Integrated with Dexcom G6 continuous glucose monitoring (CGM), Control-IQ technology requires no fingersticks for calibration or diabetes treatment decisions.²

In a recent six-month study of children age 6 to 13 using the t:slim X2 pump with Control-IQ technology, sensor time in range (TIR) increased to 67 percent from 53 percent compared to those in the control group using sensor-augmented pump (SAP) alone (p<0.001). Overnight, children using Control-IQ technology in the same study stayed in range an average of 80 percent of the time, compared to 54 percent in the control group. This data from the International Diabetes Closed Loop Protocol-5 (DCLP5) study, funded by the National Institutes of Health (NIH), was presented earlier this year at the 13^th International Conference on Advanced Technologies and Treatments for Diabetes (ATTD) in Madrid, Spain.³

“Nearly 40,000 t:slim X2 users have updated their pump with our revolutionary Control-IQ technology,” said John Sheridan, president and CEO of Tandem Diabetes Care. “The overwhelmingly positive benefits that people report experiencing can now be offered to a broader group of children with diabetes, which is particularly important as younger people often struggle with their glucose control.”

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. 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 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.⁴

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,⁵ and the ability to share real-time CGM data with up to 10 followers.⁶

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 pumps,⁷ 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.

Important Safety Information for the t:slim X2 insulin pump with Control-IQ technology

Caution: 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 an alternate controller enabled (ACE) pump that 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 t:slim X2 pump is indicated for use in individuals 6 years of age and greater. Control-IQ technology: Control-IQ technology is intended for use with a compatible integrated continuous glucose monitor (iCGM, sold separately) and ACE pump 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 six years of age and greater.

BOXED WARNING: Control-IQ technology should not be used by anyone under the age of six 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.

Control-IQ technology is not indicated for use in pregnant women, people on dialysis, or critically ill patients. Do not use Control-IQ technology if using hydroxyurea. Users of the t:slim X2 pump and Control-IQ technology must: use the insulin pump, CGM, and all other system components in accordance with their respective instructions for use; test blood glucose levels as recommended by their healthcare provider; demonstrate adequate carb-counting skills; maintain sufficient diabetes self-care skills; see healthcare provider(s) regularly; and have adequate vision and/or hearing to recognize all functions of the pump, including alerts, alarms, and reminders. The t:slim X2 pump, transmitter, and sensor must be removed before MRI, CT, or diathermy treatment. Visit tandemdiabetes.com/safetyinfo for additional important safety information.

Insulin Pump Use and Diabetes

Diabetes is a chronic, life-threatening disease that affects more than 30 million people in the United States, or nearly 1 in 10 Americans. Tandem estimates that more than three million people in the United States require daily administration of insulin and are candidates for pump therapy. More than 500,000 Americans with type 1 diabetes use an insulin pump, or approximately 30 percent of the type 1 diabetes population. In addition, approximately 100,000 Americans with type 2 diabetes use an insulin pump, which is less than 10 percent of the type 2 diabetes population using intensive insulin therapy management.
