What this trial studies

This clinical trial evaluates the effectiveness of a hybrid automated insulin delivery (AID) system in managing glucose levels and gastrointestinal symptoms in patients with type 1 diabetes complicated by gastroparesis. Participants will undergo a 2-week run-in period before being randomized to either a control group or the AID intervention using the 780G system for a total of 12 weeks. The study includes a combination of face-to-face and remote visits, as well as telephone consultations, to monitor outcomes and ensure participant engagement throughout the trial. The primary focus is on assessing improvements in glucose control and patient-reported outcomes related to gastrointestinal function.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with type 1 diabetes for over a year and experiencing symptoms of gastroparesis.

Not a fit: Patients who are currently using an automated insulin delivery system or have severe renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve glucose management and quality of life for patients with type 1 diabetes and gastroparesis.

How similar studies have performed: While automated insulin delivery systems have shown promise in other studies, this specific application for patients with gastroparesis is relatively novel.
