Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In pregnancies associated with diabetes, lowering glucose to the recommended targets to prevent adverse health outcomes often leads to significant hypoglycemia. Hybrid closed-loop (HCL) therapy, automated insulin delivery using an insulin pump getting feedback from a continuous glucose monitor (CGM), may improve outcomes. This exploratory, novel pilot feasibility randomized clinical trial will evaluate pregnant women with type 1 diabetes (T1D) on HCL therapy or Sensor-Augmented Pump Therapy (SAPT, non-communicating pump and CGM) from the 2nd trimester, throughout pregnancy, and 4-6 weeks post-partum. Comparisons will be made on safety (Specific Aim \[SA\] 1), indices of glycemic variability and fear of hypoglycemia (SA 2), and quality of life and device satisfaction (SA 3) between groups. Exploratory SA 4 will compare maternal and fetal outcomes between groups. Safety data will include episodes of severe hypoglycemia requiring 3rd party assistance, diabetic ketoacidosis, and skin reactions. Glycemic control will be measured by CGM time spent in glucose ranges (\<63, 63-140, \>140 mg/dL) and other measures of glycemic variability. Subjects will fill out surveys (Fear of Hypoglycemia, a quality of life survey, and 2 questionnaires about device satisfaction) at baseline, throughout gestation, and early post-partum. Data on maternal and fetal outcomes will be collected. Findings will reveal the safety profile and glucose control with a novel therapy for pregnant women with type 1 diabetes.
