Evaluation of Two Levels of Health Care Interactions in Adolescents With Type 1 Diabetes on Advanced Hybrid Closed Loop System MiniMed 780G/ Zeus Sensor
In Brief
A clinical study evaluating Regular Protocol with advanced carbohydrate counting and Simplified Protocol with fixed carbohydrate content for Diabetes type1. Completed, enrolled 34 participants across 1 site.
Detailed Summary
Background and Aim. The new and advanced hybrid closed loop (AHCL) system MiniMed 780G automatically adjusts basal insulin delivery in addition to automated bolus corrections, based on continuous glucose monitoring (CGM) readings, to offer protection against both hyperglycemia and hypoglycemia. The objective of this study is to evaluate whether a simplified approach for patients' follow up using preset of pump settings and a simplified meal announcement, followed by minimal interaction can achieve similar glycemic control of AHCL system MiniMed 780G with Guardian Sensor 4 than a regular protocol that is currently used in adolescents with Type 1 Diabetes (T1D). Methods. This study is Randomized Clinical Trial, two arm, single-center, clinical investigation in subjects with type 1 diabetes on AHCL insulin pump in a period of 3 months. A total of 34 individuals (age 12-18 years) will be enrolled to reach 30 individuals who will complete the 3 months study. Participants will be randomized in two groups: Group 1, Regular Clinical Protocol, 17 participants and Group 2, Simplified Clinical Protocol, 17 participants. All patients will be recruited during the regular clinic visits to the outpatient Endocrine Clinics at Sidra Medicine in Doha. Patients will be chosen on a first-come first-served basis. Inclusion criteria: Clinical diagnosis of type 1 diabetes, , Age 12-18 years, Basal Bolus therapy \>8.0 units per day. Exclusion criteria: Diabetic Ketoacidosis (DKA) in the 6 months prior to screening visit. The initiation protocol consists of four stages: HCL system compatibility assessment, HCL system training, Manual Mode Start and Auto Mode start. Patients will have 7 visits in a period of 3 months after initiation of insulin pump therapy. Pump initiation: Group 1, Finetune ICR, Target 100 or 110 mg/dl and AIT: 2-3 hour and Group 2, Carb Ratio by formula 360 / TDD, ICR 8-10 (TDD 40-60), ICR 5-7 (TDD \>60), Target 100 mg/dl, AIT: 2 hours with fixed meals Results. No group difference in Time in Range (TIR) (70-180mg/dl) \> 70% and HbA1c \< 7.5% in a period of 3 months after initiation of AHCL. Conclusion. Conclusions will be drawn on completion of the study and evaluation of the results.

Timeline
Interventions
* Review 3 Days CGM data in Manual Mode * Carb Ratio by formula 360 / TDD * Finetune ICR * Target 100 or 110 mg/dl * AIT: 2-3 hour * Insulin Bolus for meal (advanced carb counting) * The parameters will be set using clinical assessment and fine-tuned if needed on F-up visits. * Follow up visits will be scheduled Day 7, 14,28, 56 and 84 after enabling SmartGuard (AHCL use).
* Review 3 Days CGM data in Manual Mode * Carb Ratio by formula 360 / TDD ICR 8-10 (TDD 40-60) ICR 5-7 (TDD \>60) * Target 100 mg/dl * AIT: 2 hours * Insulin Bolus for meal (Thee sets of meal set of meals announcement carbs will be provided) Regular meal: Total Carbs per Day x 0.6 / 3 Large meal: Total Carbs per Day x 0.6 / 3 x 1.5 Small (Snack) meal: Total Carbs per Day x 0.6 / 3 x 1.5 * Total carbs per day will be calculated as average on 7-days Food Logbook diary, provided by participant, one week before AHCL initiation. * The parameters will be fixed and fine-tuned only in case of hypoglycemia on F-up visits.
