NCT07011147 | RECRUITING | Type 1 Diabetes (T1D)

Primary Care Pragmatic, Real World Experience for Automated Insulin Delivery
Sponsor:

University of Colorado, Denver

Brief Summary:

The goal of this randomized controlled trial is to compare the efficacy and safety of the iLet Bionic Pancreas (BP) System in adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes) compared to standard of care when ordered by primary care providers. The main question it aims to answer is: Can the iLet BP by deployed in primary care settings to adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes)? Researchers will compare 13-weeks of iLet BP use to routine care to see if iLet BP use has a greater reduction in HbA1c compared to13-weeks of routine care. Participants will: Use the iLet BP for 13-weeks or continue their routine care Be trained to use the study devices or continue their routine care Complete a virtual screening visit, mid-period follow up calls and a final visit Complete baseline CGM collection Complete surveys and fingerstick a1c blood tests Routine care participants will have the option to complete an observational extension phase where they will wear the iLet BP for 13-weeks

Acceptable methods of contraception include: i. Combined estrogen and progestogen containing hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal).
    • ii. Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable).
    • iii. Placement of an intrauterine device or intrauterine hormone-releasing system.

    • v. Has a vasectomized or sterile partner (where partner is sole partner of participant) and where vasectomy has been confirmed by medical assessment.
    • vi. Exercises true sexual abstinence. Sexual abstinence is defined as refraining from heterosexual intercourse during the entire period of risk associated with the study.

    Exclusion Criteria
    • 1. Unable to safely comply with study procedures and reporting requirements (e.g. impairment of vision or dexterity that prevents safe operation of the bionic pancreas, impaired memory)
    • 2. Unable to speak and read English, as iLet BP support materials and device menus are currently available in English only
    • 3. Diagnosis of maturity-onset diabetes of the young (MODY)
    • 4. Plan to change usual diabetes regimen between screening and study randomization
