Diabeloop Control Algorithm Integrated In An External Device Improves Glycemic Control In Type 1 Diabetes Patients

A new study by Ana Chico and team showing a first real-world trial of the closed-loop system, Accu-Chek Insight with Diabeloop, found a substantial improvement in glycemic control without major side events and a high level of patient satisfaction.  The findings of this study were published in Diabetes Technology & Therapeutics.  This research examined persons with type I diabetes (T1D) in real-world settings to access the effectiveness, safety and satisfaction of the closed-loop system Accu-Chek® Insight with Diabeloop (DBLGI).

The Diabeloop control algorithm, which has the ability to self-learn, controls insulin administration using CGM data, carbohydrate consumption, and physical activity.

Participants were T1D patients who had been utilizing DBLGI for at least three (3) months.  At the beginning of DBLGI, as well as 1, 2, and 3 months later, glucometric parameters were examined.  HbA1c was assessed prior to and after three (3) months.  The patients answered a satisfaction survey, and technical problems and serious consequences were noted.

The key findings of this study were:

  1. There were 62 patients total (43 women; 44.2 11 years old; 24.6 12 years with diabetes; 40 using flash and 22 using continuous glucose monitoring (CGM); 45 using an insulin pump and 17 using numerous daily injections).
  2. Early in the first month, a considerable improvement was seen in the glucose measures collected from the CGM; Time within the range (%TBRI) 54-70 mg/dL; time below range level 2 (%TBR2) 54 mg/dL; %CV, median glucose, and %GMI.
  3. Additionally, HbA1c dramatically dropped.
  4. There were no major adverse effects or immediate problems.
  5. Regardless of previous therapy or the kind of glucose monitoring device utilized, the same improvement was seen.
  6. 21 patients had technical problems, and three (3) patients stopped using DBLG1.
  7. Patient satisfaction was good overall.
  8. Adjustments to the parameters were often made to make them more aggressive.

In conclusion, the administration of DBLG1 was safe and significantly improved glycemic control and patient satisfaction.
