Trial Outcomes & Findings for Research Study to Look at Fast-acting Insulin Aspart With the Insulin Pump System 'iLet™' in Adults With Type 1 Diabetes (NCT NCT03816761)

NCT ID: NCT03816761

Last Updated: 2020-06-11

Results Overview

Interstitial glucose: glucose measured in interstitial fluid. Time in low interstitial glucose (defined as below 54 mg/dL \[3 mmol/L\]) from initiation of treatment (day 1) to end of treatment (day 7). Time spent in low interstitial glucose is calculated as the percentage of available interstitial glucose values below the threshold.

Cohort 1: t65 First, Then t50
iLet™ is a new insulin pump that is programmed to work with a Continuous Glucose Monitoring (CGM) device. Participants received fast-acting insulin aspart with the iLet™ having default tmax in the algorithm settings (t65 = 65 minutes) for 7 days. After 7 days they received fast-acting insulin aspart with the iLet™ having non-default tmax in the algorithm settings (t50 = 50 minutes) for 7 days. The total treatment duration for each cohort was 14 days.

SECONDARY outcome

Timeframe: Day 1 to day 7

Population: Safety analysis set (SAS): included all subjects receiving treatment. Number of participants analysed=participants with available data.

Number of treatment emergent severe hypoglycaemic episodes from initiation of treatment (day 1) to end of treatment (day 7). Treatment emergent is defined as an episode that has onset in the period from initiation of treatment to end of treatment. Severe hypoglycaemia: An episode requiring assistance of another person to actively administer carbohydrate, glucagon or take other corrective actions. Plasma glucose (PG) concentrations may not be available during an event, but neurological recovery following the return of PG to normal is considered sufficient evidence that the event was induced by a low PG concentration.

Mean number of self-manageable (able to self-treat) treatment emergent hypoglycaemic episodes that require oral carbohydrate intervention per day. Self-manageable (able to self-treat) hypoglycaemic episodes that require oral carbohydrate intervention per day is calculated as the sum of all hypoglycaemic episodes where the subject is able to self-treat and that require oral carbohydrate intervention divided by the actual duration of the treatment period in days. Treatment emergent is defined as an episode that has onset in the period from initiation of treatment to end of treatment.

ADA classification of hypoglycaemia: 1. Severe hypoglycaemia: An episode requiring assistance of another person to actively administer carbohydrate, glucagon or take other corrective actions. 2. Asymptomatic hypoglycaemia: An episode not accompanied by typical symptoms of hypoglycaemia, but with a measured PG concentration ≤3.9 mmol/L (70 mg/dL). 3. Documented symptomatic hypoglycaemia: An episode during which typical symptoms of hypoglycaemia are accompanied by a measured PG concentration ≤ 3.9 mmol/L (70 mg/dL). 4. Pseudo-hypoglycaemia: An episode during which the person with diabetes reports any of the typical symptoms of hypoglycaemia with a measured PG concentration \> 3.9 mmol/L (70 mg/dL) but approaching that level. 5. Probable symptomatic hypoglycaemia: An episode during which symptoms of hypoglycaemia are not accompanied by a PG determination but that was presumably caused by a PG concentration ≤ 3.9 mmol/L (70 mg/dL).

Population: Safety analysis set (SAS): included all subjects receiving treatment. Number of participants analysed=participants with available data.

ADA classification of hypoglycaemia: 1. Severe hypoglycaemia: An episode requiring assistance of another person to actively administer carbohydrate, glucagon or take other corrective actions. 2. Asymptomatic hypoglycaemia: An episode not accompanied by typical symptoms of hypoglycaemia, but with a measured PG concentration ≤3.9 mmol/L (70 mg/dL). 3. Documented symptomatic hypoglycaemia: An episode during which typical symptoms of hypoglycaemia are accompanied by a measured PG concentration ≤ 3.9 mmol/L (70 mg/dL). 4. Pseudo-hypoglycaemia: An episode during which the person with diabetes reports any of the typical symptoms of hypoglycaemia with a measured PG concentration \> 3.9 mmol/L (70 mg/dL) but approaching that level. 5. Probable symptomatic hypoglycaemia: An episode during which symptoms of hypoglycaemia are not accompanied by a PG determination but that was presumably caused by a PG concentration ≤ 3.9 mmol/L (70 mg/dL).

Participants received fast-acting insulin aspart with the iLet™ having non-default tmax in the algorithm settings (t30 = 30 minutes) in cohort 3. The total treatment duration for each cohort was 14 days with each cross-over period of the 2 tmax settings being 7 days.
t65 Faster Aspart Cohort 3
n=7 Participants
Participants received fast-acting insulin aspart with the iLet™ having default tmax in the algorithm settings (t65 = 65 minutes) in cohort 3. The total treatment duration for each cohort was 14 days with each cross-over period of the 2 tmax settings being 7 days.

SECONDARY outcome

Timeframe: Day 1 to day 7

Population: Full analysis set: Included all randomised subjects receiving treatment. Number of participants analysed=participants with available data.

Total insulin dose (U/kg) per day from initiation of treatment (day 1) to end of treatment (day 7). Total daily insulin dose is calculated as the sum of all insulin doses delivered by the iLet™ divided by the actual duration of the treatment period in days.
