Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized cross-over trial assessing glycemic control on Automated insulin delivery as Adaptive Network (AIDANET) algorithm when used in three modes: AIDANET-Fully Closed Loop (FCL), AIDANET-Hybrid Closed Loop (HCL) and AIDANET allowing a mix between FCL and HCL. There will be an Automated Insulin Delivery (AID) phase with participants using their home devices and/or study continuous glucose monitor (CGM) and study-provided commercial Mobi system without AIDANET.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a randomized cross-over trial comparing AIDANET used in three different modalities to currently available AID systems (usual care). For two 4-week phases the participants will first use the system in predetermined modality (HCL or FCL) in random order. The AIDANET system is designed to work both in full closed loop (no meal information) and in hybrid closed-loop, with carbohydrate announcement (standard bolus calculator) or easy bolus (announce timing but not carbohydrate amount), as requested by the user. During a third 4-week long phase, all participants will continue to use the system as befits their preferences (no modality will be imposed, and the user is free to go back and forth between modalities). In addition, the participant will spend 4 weeks using a usual care AID system either before the first AIDANET phase (randomization Group A) or after the last AIDANET phase (randomization Group B).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A

Group A: AID first followed by AIDANET-FCL, AIDANET-HCL and then AIDANET-FCL-HCL mix

Group Type EXPERIMENTAL

AIDANET + FCL

Intervention Type DEVICE

All participants will use AIDANET in fully closed loop (FCL) mode with instructions to avoid announcing meal boluses whenever possible during the four weeks.

AIDANET + HCL

Intervention Type DEVICE

All participants will use AIDANET in hybrid closed loop (HCL) mode with instructions to announce all meal boluses using carbohydrate counting or easy bolus during the four weeks. All components of AIDANET will remain active during this phase but BPS in particular is expected to be triggered less often due to meal announcements.

AIDANET in FCL-HCL-mixed mode

Intervention Type DEVICE

All participants will use AIDANET with instructions to choose whether to use fully closed loop (FCL) or hybrid closed loop (HCL) mode with meal announcements (carb counting or easy bolus) per their discretion each day.

Automated Insulin Delivery (AID) (usual care)

Intervention Type OTHER

Participants will manage their diabetes as they normally do at home.

Group B

Group B: AIDANET-FCL first followed by AIDANET-HCL, AIDANET- FCL-HCL mix and AID

Group Type EXPERIMENTAL

AIDANET + FCL

Intervention Type DEVICE

All participants will use AIDANET in fully closed loop (FCL) mode with instructions to avoid announcing meal boluses whenever possible during the four weeks.

AIDANET + HCL

Intervention Type DEVICE

All participants will use AIDANET in hybrid closed loop (HCL) mode with instructions to announce all meal boluses using carbohydrate counting or easy bolus during the four weeks. All components of AIDANET will remain active during this phase but BPS in particular is expected to be triggered less often due to meal announcements.

AIDANET in FCL-HCL-mixed mode

Intervention Type DEVICE

All participants will use AIDANET with instructions to choose whether to use fully closed loop (FCL) or hybrid closed loop (HCL) mode with meal announcements (carb counting or easy bolus) per their discretion each day.

Automated Insulin Delivery (AID) (usual care)

Intervention Type OTHER

Participants will manage their diabetes as they normally do at home.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age ≥18.0 years old at time of consent
2. Clinical diagnosis, based on investigator assessment, of Type 1 Diabetes for at least one year.
3. Having used an Food and Drug Administration (FDA) approved AID system within the last six months (can be intermittent use).
4. Currently using insulin for at least six months.
5. Willingness to switch to use an FDA-approved personal insulin for the study pump (e.g., lispro or aspart, or biosimilar FDA-approved products) as directed by the study team.
6. Has one or more supportive companions knowledgeable about emergency procedures for severe hypoglycemia and able to contact emergency services and study staff who either lives with participant or located within approximately 30 minutes of participant and able to locate participant in the event of an emergency.
7. Participant not currently known to be pregnant or breastfeeding.
8. If participant capable of becoming pregnant, must agree to use a form of contraception to prevent pregnancy while a participant in the study (e.g. hormonal contraception, abstinence from heterosexual intercourse). A negative serum or urine pregnancy test will be required for all participants of childbearing potential. Participants who become pregnant will be discontinued from the study. Also, participants who during the study develop and express the intention to become pregnant within the timespan of the study will be discontinued.

10. Willingness to use the study AIDANET system (CGM, pump, and phone) during the relevant study periods.

Exclusion Criteria

1. Plans to start a new non-insulin glucose-lowering agent (e.g. glucagon-like peptide-1 (GLP-1) receptor agonists, Symlin, (DPP-4 inhibitors, also known as dipeptidyl peptidase 4). Participants may be on a stable dose of such an agent for at least the past month.
2. Current use of sulfonylurea medications.
