Fully closed-loop control with ultra-rapid versus standard insulin lispro: A randomised crossover study simulating missed meal boluses.

ABSTRACT:

Aims

Ultra-rapid insulin lispro (URIL) is associated with faster insulin absorption and earlier offset than standard insulin lispro (IL). This study evaluated whether URIL improves glucose control in a fully closed-loop setting over an 8-h period compared to IL under conditions simulating a missed meal bolus.

Methods

In this open-label, randomised crossover trial, 18 adults with type 1 diabetes using insulin pump therapy [12 females, age 39.1 (14.2) yrs., HbA1c 57.9 (8.7) mmol/mol] completed two 8-h inpatient sessions (09:00 to 17:00 h). Glucose levels were managed using the CamAPS FX closed-loop system with either URIL or IL, in random order. Participants received a standardised meal at 11:00 h without a meal bolus. The primary endpoint was the percentage of time in range (
