Reduction of Nocturnal Hypoglycemia and Hyperglycemia in the Home Using Predictive Algorithms

Objective: to gain experience with in-home use of a modified algorithm that will dose insulin to minimize projected hyperglycemia overnight in addition to suspending the pump if hypoglycemia is projected overnight and to obtain feasibility, safety, and initial efficacy data.

Study Design: randomized controlled trial, with randomization on a night level within subject.

Major Eligibility Criteria: clinical diagnosis of type 1 diabetes, daily insulin therapy for at least one year and an insulin infusion pump for at least 6 months; 15.0 to <46.0 years of age; HbA1c < 10.0%; no DKA in last 6 months; no hypoglycemic seizure or loss of consciousness in last 6 months; Living with a significant other or family member ("companion") committed to participating in all study activities, and being present and available to provide assistance when the system is being used at night.

Sample Size: 30 subjects.

Study Duration and Visit Schedule: duration approximately 3 months, with preliminary run-in activities followed by up to 90 days spent in clinical trial phase of study; clinic visits at enrollment, following CGM and system assessment run-in phases, at start of clinical trial phase, at 21-day point of clinical trial phase, and after 42 nights of successful system use.

Major Efficacy Outcomes:

- Primary: time in range (70-180 mg/dl, 3.9-10.0 mmol/L) overnight.

- Secondary: time spent in hypoglycemia (≤70 mg/dl, 3.9 mmol/L) and time spent in hyperglycemia (>180 mg/dl, 10.0 mmol/L) overnight.

Major Safety Outcomes: CGM measures of hypo- and hyperglycemia, including morning blood glucose and mean overnight sensor glucose; adverse events including severe hypoglycemia and diabetic ketoacidosis.
