Simplified Meal Approach Using Hybrid Closed-loop Insulin Delivery in Youth and Young Adults With Type 1 Diabetes — SMASH  

Type 1 Diabetes Clinical Trial

Official title:
Simplified Meal Approach Study Using Hybrid Closed-loop Insulin Delivery in Youth and Young Adults With Type 1 Diabetes - a Randomised Controlled Two-centre Crossover Trial

Clinical Trial Summary

The purpose of the study is to examine whether a simplified meal approach (as compared to exact carbohydrate counting) can alleviate the need of carbohydrate counting without worsening postprandial control in youth and young adults with type 1 diabetes using hybrid closed-loop insulin delivery with the Cambridge Artificial Pancreas FX System (CamAPS FX system).

Clinical Trial Description

Optimal glycaemic control is the aim of diabetes care and critical in the prevention of diabetes-related complications. Despite advances in diabetes technologies and medications, many current youth and young adults (YYA) with type 1 diabetes (T1D) are not meeting desired glycaemic targets, representing a missed opportunity for improving lifetime outcomes. A variety of factors including peer group influences, importance of body image, less parental oversight, greater risk-taking, and performance pressure challenge daily self-management in YYA with T1D. Disengagement from care and barriers for optimal glycaemic management in YYA have been mainly shown to be substantially influenced by perceived burden of daily tasks. Although the recently introduced closed-loop systems, which link insulin delivery to sensor glucose levels, offer promising opportunities to improve glucose control in YYA with T1D, they still require the user to estimate carbohydrates. The perceived burden of exact carbohydrate counting (ECC), the limited evidence supporting its glycaemic benefit and corrective potential of algorithm-driven background insulin titration question its necessity during hybrid-closed loop insulin treatment. Instead, a simplified meal approach (SMA), which only requires the user to select the meal carbohydrate category (small/medium/large), has the potential to alleviate the burden of ECC during hybrid closed-loop insulin therapy whilst resulting in similar glycaemic benefits. The investigators therefore hypothesize that a simplified meal approach (SMA) using the CamAPS FX system would achieve comparable glucose control compared with the use of the CamAPS FX system with ECC in YYA with T1D. ;
