Summary

Individuals with diabetes secondary to pancreatectomy experience impaired quality of life, partly due to the challenges of managing highly variable blood glucose levels. Hybrid closed-loop (HCL) automated insulin delivery (AID) systems, widely evaluated in type 1 diabetes, may improve both metabolic outcomes and quality of life in this population. A review of the literature identified a few observational studies reporting promising results with HCL systems in the context of post-pancreatectomy diabetes. Only one randomized trial has evaluated AID in this population, showing excellent outcomes, but using a complex bihormonal system that is not yet commercially available worldwide. Consequently, there remains a lack of confirmatory evidence regarding the efficacy of commercially available monohormonal HCL systems in individuals with diabetes secondary to pancreatectomy, evidence that is crucial to support broader access to this technology. The intervention will consist in a 3-month AID treatment combining MiniMed 780 and Simplera. The control period will consist in 3 months using the Simplera for continuous glucose monitoring, alongside participant usual diabetes treatment. The primary outcome is the percentage of time that interstitial glucose levels remain within the target range (70-180 mg/dL), as measured by continuous glucose monitoring (CGM, Simplera), over a 3-month period using the MiniMed 780 hybrid closed-loop system, compared to a 3-month period under the participant's usual diabetes treatment.

Detailed description

The MiniMed 780G system comprises an external insulin pump with a subcutaneous infusion catheter inserted by the participant using a dedicated insertion kit. The infusion set is placed in the abdomen, buttocks, thighs, or upper arms, following standard hygiene procedures. The Simplera system consists of an all-in-one external continuous glucose sensor inserted subcutaneously in the back of the upper arm via a dedicated insertion device.
