Observational Deka Research and Development · NCT07356089

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
