Postmarket monitoring of twiist automated insulin delivery for people with Type 1 diabetes
Official title: Twiist Postmarket Surveillance Study in Adults and Youth With Type 1 Diabetes
Run by Deka Research and Development · NCT07356089 · Data updated 2026-11-12
This project will collect real-world data from people age 6 and older with Type 1 diabetes who recently started using the twiist automated insulin delivery system to see how it works for them over 12 months.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are U.S. residents age 6 or older with a diagnosis of Type 1 diabetes who started using the twiist system within the prior 90 days, are willing to share device and support data, complete monthly surveys for 12 months, and are not pregnant or planning pregnancy.
✕Probably not a fit
People younger than 6, those not using twiist or who started twiist more than 90 days before enrollment, non-U.S. residents, or those unwilling to share device data or complete monthly surveys are unlikely to benefit from this surveillance.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a postmarket observational surveillance following youth and adults (≥6 years) with Type 1 diabetes who began using the twiist AID system within 90 days of enrollment. Participants will allow twiist device data and any customer-support reports to be used and will complete a baseline survey and monthly surveys for 12 months. The study may request medical records for any hospitalizations and requires U.S. residency and regular cellular or weekly Wi‑Fi access for uploads. Data collection is coordinated with Jaeb Center for Health Research and the device sponsor to characterize real-world safety, device use patterns, and clinical outcomes.
Why it matters
Potential benefit: If successful, this could show whether twiist helps people with Type 1 diabetes manage glucose control, is safe in everyday use, and is user-friendly.
How similar studies have gone: Other automated insulin delivery systems have shown improvements in time-in-range and fewer hypoglycemia events in clinical and real-world studies, but twiist-specific postmarket evidence is currently limited.
