New insulin pump system put to the test in 400-Person safety trial
NCT ID NCT07228117
First seen Jun 26, 2026 · Last updated Sep 03, 2026 · Updated 9 times
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.

Inclusion Criteria: 1. Age at time of screening according to diabetes type: 1. T1D: Age 7-85 years 2. T2D: Age 18-85 years 2. Has a clinical diagnosis of diabetes for a minimum per diabetes type below: 1. T1D (Age 7-85 years): Diagnosis of T1D for at least 6 months, as determined via medical record or source documentation by an individual qualified to make a medical diagnosis. 2. T2D (Age 18-85 years): Diagnosis of insulin-requiring T2D for 1 year or more, as determined via medical record or source documentation by an individual qualified to make a medical diagnosis 3. Is willing to provide informed consent/assent for participation. 4. Subject or parent/caregiver is literate and able to read the language (English or Spanish) offered in the study pump or study pump materials. 5. 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.
