Hybrid Closed-Loop Insulin Delivery After Pancreatectomy (HCL PP)

May 26, 2026 updated by: Centre Hospitalier Sud Francilien

Metabolic Effects of Hybrid Closed-loop Insulin Delivery in People With Diabetes After Pancreatectomy: a Randomized Cross-over Controlled Trial

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
