“This study demonstrated that in school-aged children with type 1 diabetes, who often struggle with diabetes management for a variety of reasons, use of Control-IQ technology led to improved glucose control during both the day and night,” said Dr. Wadwa. “We are thrilled with these results and are hopeful that this system will ultimately offer a valuable treatment option to benefit children with type 1 diabetes.”
The DCLP5 study is a 16-week closed-loop study that included a dedicated control group, increasing the clinical significance of the study results. There were no exclusion criteria based on hemoglobin A1c (HbA1c), history of acute complications, or previous experience using an insulin pump or CGM. Following a two to eight-week run-in period, the length of which was determined based on previous pump and CGM experience, 101 patients with type 1 diabetes ages 6 to 13 were randomized 3:1 to Control-IQ technology (n=78) or sensor-augmented pump (SAP) therapy (n=23) and followed for 16 weeks. The entry HbA1c for participants in the study ranged from 5.7 to 10.1 with a mean of 7.9 in the SAP group and 7.6 in the Control-IQ technology group. Approximately 20 percent of participants were new to pump therapy and the large majority were already using a CGM. All participants completed the study.
Time in range (70 mg/dL – 180 mg/dL)1 for children using Control-IQ technology for 6 months increased from 53 percent to 67 percent, compared to those in the control group who increased from 51 percent to 55 percent using SAP alone (p<0.001). During the overnight period, sensor time in range with Control-IQ technology was 80 percent compared to 54 percent in the control group.
Time spent with sensor glucose values above 180 mg/dL was 31 percent in those using Control-IQ technology compared to 43 percent in the control group (p<0.001). Sensor time spent below 70 mg/dL was very low at baseline (<2 percent in both treatment groups) and not different between groups at the 16-week follow up interval. These results were demonstrated in people with and without prior experience with insulin pump therapy. The treatment effect was evident in the first month and appeared consistent over 4 months. In addition to sensor time in range, those using Control-IQ technology also saw statistically significant reductions in mean sensor glucose.
No severe hypoglycemia or diabetic ketoacidosis (DKA) was reported in the study. The system operated in active closed-loop 93 percent of the 4-month time period.
International Diabetes Closed Loop Protocol-3 (DCLP3) Study Results
A review of the evolution of Control-IQ technology, and a summary of available Control-IQ clinical data was presented by Dr.
The NIH-funded DCLP3 study was the first large-scale, 6-month closed-loop study that included a dedicated control group. There were no exclusion criteria based on hemoglobin A1c (HbA1c), history of acute complications, or previous experience using an insulin pump or CGM. Time in range (70 mg/dL – 180 mg/dL)1 for participants using Control-IQ technology for 6 months averaged 71 percent compared to 59 percent for participants in the control group using SAP alone (p<0.0001). During the overnight period, sensor time in range with Control-IQ technology averaged 76 percent compared to 59 percent in the control group (p<0.0001). Time spent with sensor glucose values above 180 mg/dL was 27 percent in those using Control-IQ technology compared to 39 percent in the control group (p<0.001). Sensor time spent below 70 mg/dL was 1.4 percent with Control-IQ technology compared to 1.9 percent in the control group (p<0.001), and sensor time spent below 54 mg/dL was 0.21 percent compared to 0.24 percent in the control group (p=0.02). These results were demonstrated in participants with and without prior insulin pump therapy experience. In addition to sensor time in range, those using Control-IQ technology also saw statistically significant improvements in HbA1cand reductions in mean glucose. One report of diabetic ketoacidosis (DKA) was reported in the Control-IQ study arm due to an infusion set issue. No severe hypoglycemia was reported in the study.

About Control-IQ Advanced Hybrid Closed Loop Technology
The t:slim X2 insulin pump with Control-IQ technology uses Dexcom G6 CGM values, in conjunction with other variables such as insulin on board, to predict sensor glucose levels 30 minutes ahead and adjust insulin delivery accordingly2,3,4. 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 and delivers a correction bolus with a target of 110 mg/dL once an hour as needed. Control-IQ technology also offers optional settings for sleep and exercise that will change treatment values to better match the different physiologic needs during these activities.
About Basal-IQ Predictive Low Glucose Suspend Technology
The simple-to-use t:slim X2 insulin pump with Basal-IQ predictive low glucose suspend technology uses glucose values from an integrated Dexcom G6 continuous glucose monitor to predict and help prevent lows with zero fingersticks2,3,4. Basal-IQ technology uses CGM values to help reduce the frequency and duration of low-glucose events by predicting glucose levels 30 minutes ahead and suspending insulin if they are expected to drop below 80 mg/dL or if a CGM reading falls below 70 mg/dL. Insulin delivery resumes as soon as sensor glucose values begin to rise.
Important Safety Information:
Caution: Federal (
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 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.
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 tandemdiabetes.com/safetyinfo.
