Summary

This study is checking if a new insulin pump (NMX8) and continuous glucose monitor (DS5/Simplera Sync) are safe for people with type 1 or type 2 diabetes. About 400 participants, ages 7 to 85, will first wear the sensor for up to 40 days, then use the pump for about 90 days while logging meals and exercise. The goal is to see how well the system keeps blood sugar in a healthy range and avoids dangerously low levels.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MiniMed™ NMX8-AID insulin pump with DS5™/Simplera Sync™ continuous glucose monitor
What this could lead to
If successful, this could lead to a safer, more convenient insulin pump system that helps people with diabetes better manage their blood sugar levels.
What could go wrong
This is an early safety study, not a large-scale effectiveness trial. The device may not improve outcomes for everyone, and there are always risks like pump malfunction or skin reactions.

Is willing to wear the system continuously throughout the study. 6. Has results of a retinal eye examination on record prior to enrollment, per guidelines by the American Diabetes Association according to age, duration of diabetes and type of diabetes: 1. T1D adults (Age 18-85 years): I. Initial retinal eye exam within 5 years of diagnosis. II. If the duration of type 1 diabetes is longer than 5 years, a retinal examination should have been performed within the last 12-18 months. 2. T2D adults (Age 18-85 years): I. Results of a retinal eye exam, performed within the last 12-18 months, should be on record. 3. T1D pediatric (Age 7-17 years): I. No exam is required if under the age of 10 years unless the duration of diabetes is more than 3 years. II. For children over the age of 10, a retinal exam should have been performed within 24 months of enrollment in the study. Per the investigator's discretion: If a potential participant is deemed to be at high risk, a retinal eye exam, performed within the last 12 months prior to screening, should be on record. 7. Is willing to upload study pump data via an app or computer. 8. Is willing to take one of the following insulins and can financially support the use of insulin preparations as required by the study: 1. Humalog™\* (insulin lispro injection) 2. NovoLog™\* (insulin aspart solution for injection) or an interchangeable biosimilar (for example, Kirsty™\*) 3. NovoRapid™\* (insulin aspart solution for injection) 4. Admelog™\* (insulin lispro injection) 5. Merilog™\* (insulin aspart) 6. Fiasp™\* (ultra-rapid-acting insulin aspart) 7. Lyumjev™\* (ultra-rapid-acting insulin lispro) 8.
