• Registration Number: NCT07227805
• Lead Sponsor: Medtronic Diabetes

Brief Summary

This study will demonstrate the safety and performance of the Novel Medtronic Experimental Automated Insulin Delivery system named MiniMed™ NMX8 system in people living with insulin-requiring diabetes in comparison with the MiniMed™ 780G system.

Detailed Description

This study is a pre-market, interventional, prospective, open-label, multi-center and randomized controlled clinical study.

The study consists of a run-in phase and a study phase.

Run-in Phase:

The purpose of the run-in phase is to collect baseline CGM data while subjects are on 780G therapy in Auto Mode. All subjects will use the Simplera Sync sensor.

At the end of the run-in phase, subjects will be randomly allocated to one of the two study arms (Treatment arm or Control arm).

Study Phase:

During the 12-week study phase, subjects will either start using the MiniMed™ NMX8 system (Treatment arm) or will continue to use the MiniMed™ 780G in Auto Mode (Control arm). During the study phase, all subjects will use the Simplera™ Sync sensor.

7. Investigator has confidence that the subject, parent(s)/legal guardian(s) can successfully operate all study devices and is capable of adhering to study visit schedule per protocol.
8. Subject, Parent(s)/legal guardian(s) is willing to participate in all training sessions as directed by study staff.
9. Subject, Parent(s)/legal guardian(s) is willing and able to provide written informed consent.
10. For subject with Type 2 Diabetes only: Is on stable dose of anti-diabetic medication (other than insulin) (e.g., pramlintide, DPP-4 inhibitor, GLP-1 and GIP agonists/mimetics, metformin, SGLT2 inhibitors) for the last 3 months prior to screening. NB: Subject should not change type or dose of medication during the course of the study.
