Diabetes Type 1 Closed Loop Insulin

ClinConnect Summary

The ACOLYTE Study is examining whether a new type of insulin called ultra-rapid acting lispro (Lyumjev) can help better control blood sugar levels in adults with type 1 diabetes compared to standard insulin lispro. This study is particularly interesting because it uses a fully automated system that adjusts insulin delivery based on real-time blood sugar readings. Participants will spend two separate days in a clinical facility, where they will receive controlled meals and have their glucose levels monitored to see how well each insulin type works under similar conditions.

To be eligible for this trial, participants must be at least 18 years old, have been diagnosed with type 1 diabetes for at least a year, and have been using an insulin pump for three months or longer. They should also have specific blood sugar levels (HbA1c) and be able to understand English. During the study, participants can expect to be closely monitored, and their safety will be a priority, with assessments for any low or high blood sugar episodes. This trial is currently recruiting participants at the Manchester Royal Infirmary and aims to include around 26 adults to complete the study.
