In the International Diabetes Closed Loop Trial (IDCL), Protocol 3, time in range (70-180 mg/dL)* for participants using Control-IQ™ (CIQ) technology for six months was 71% per day compared to 59% when using sensor-augmented pump (SAP) therapy alone. During the overnight period, time in range was 76% compared to 59%.1View Study Overview

Real-world use (n=2,712) of the t:slim X2 insulin pump with Basal-IQ technology demonstrated an even greater reduction in time spent in hypoglycemia compared to outcomes observed in the PLGS for Reduction of Low Glucose (PROLOG) Study (n=102).4View Results
Time Spent <70 mg/dL (%)
Time Spent <60 mg/dL (%)
In the IDCL Trial, using a 5-point scale, Control-IQ participants rated the technology a 4.7 for ease of use, 4.6 for usefulness, and 4.5 for trust.1 In the PROLOG Study, 97% of participants indicated that they felt confident using the Basal-IQ system, and 97% indicated that the system was easy to use.3

Important Safety Information
Caution: Federal (USA) law restricts the t:slim X2 insulin pump, the t:slim X2 pump with Basal-IQ technology, and Control-IQ technology to sale by or on the order of a physician. The t:slim X2 pump, the t:slim X2 pump with Basal-IQ technology, and Control-IQ technology are intended for single patient use. The t:slim X2 pump, the t:slim X2 pump with Basal-IQ technology, 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 integrated 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 pump is indicated for use in individuals 6 years of age and greater. t:slim X2 insulin pump with Basal-IQ technology: When used with a compatible integrated continuous glucose monitor (iCGM), the t:slim X2 insulin pump with Basal-IQ technology can be used to suspend insulin delivery based on CGM sensor readings. The t:slim X2 pump with Basal-IQ technology 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 14 years of age and greater. Control-IQ technology is intended for single patient use. Control-IQ technology is indicated for use with NovoLog or Humalog U-100 insulin.
|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 and the t:slim X2 pump with Basal-IQ technology are not indicated for use in pregnant women, people on dialysis, or critically ill patients. Users of the t:slim X2 pump, the t:slim X2 pump with Basal-IQ technology, and Control-IQ technology must: be able and willing to 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. For additional important safety information, visit www.tandemdiabetes.com/safetyinfo.
