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.

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.

Inclusion Criteria:

1. Is aged ≥2 years old at time of screening.
2. Has a clinical diagnosis of Type 1 or Type 2 diabetes for ≥ 6 months prior to screening as determined via medical record by an individual qualified to make a medical diagnosis.
3. Is on MiniMed™ 780G with Simplera Sync sensor for at least 3 months before screening.
4. Has a glycosylated hemoglobin (HbA1c) <11% (97 mmol/mol) at time of screening visit as processed at Point of Care (PoC) or local lab.
5. Must have a minimum daily insulin requirement (Total Daily Dose) of ≥ 6 units and a maximum of 250 units
6. Willing to switch to approved insulin per insulin pump labeling.
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.
11. For Israel only: Subject, Parents(s)/legal guardian(s) is fluent in English.

Exclusion Criteria:

1. Has Addison's disease, growth hormone deficiency, hypopituitarism or definite gastroparesis, uncontrolled coeliac disease, uncontrolled thyroid disorder, or poorly controlled asthma, per investigator judgment.
2. For subjects with Type 1 Diabetes only: Is using any anti-diabetic medication other than insulin 6 months before screening or plan on using during the study (e.g., pramlintide, DPP-4 inhibitor, GLP-1 and GIP agonists/mimetics, metformin, SGLT2 inhibitors).
3. Has taken any oral, injectable, or intravenous (IV) glucocorticoids within 8 weeks from time of screening visit, or plans to take any chronically oral, injectable, or IV glucocorticoids during the course of the study, per investigator judgement
4. Has had renal failure defined by creatinine clearance <30 ml/min, as assessed by local lab test ≤ 6 months before screening or performed at screening at local lab, as defined by the creatinine-based Cockcroft, CKD-EPI or MDRD equations.
5. Has active or severe retinopathy in the last 6 months before screening
6. Has any unresolved adverse skin conditions in the area of sensor placement (e.g. psoriasis, dermatitis herpetiformis, rash, Staphylococcus infection).
7. Has any other disease or condition that may preclude the patient from participating in the study, per investigator judgment.
8. History of 2 or more DKA events in the last 3 months before screening.
9. Has had Hyperosmolar Hyperglycemic State (HHS) in the last 6 months before screening.
10. Is using hydroxyurea at time of screening or plans to use it during the study
11. Women of child-bearing potential who have a positive pregnancy test at screening or plan to become pregnant during the course of the study.
12. Women who are breastfeeding.
13. Is actively participating in an investigational study (drug or device) wherein he/she has received treatment from an investigational study drug or device in the last 2 weeks before screening, as per investigator judgment.
14. Subject is currently abusing illicit drugs, marijuana, alcohol or prescription drugs (other than nicotine), per investigator judgment.
15. Subject, Parent(s)/legal guardian(s) are part of research staff involved with the study.
16. Subject, Parent(s)/legal guardian (s) are legally incompetent, illiterate, or vulnerable.
