Using hybrid closed-loop insulin pumps to improve diabetes management in diverse adults

Starting Technology in At Risk Type 1 Diabetes (STAR-T1D) Study

NA · University of California, Los Angeles · NCT06453928

This study is testing if a new type of insulin pump can help adults with poorly controlled Type 1 Diabetes manage their condition better, especially those from different backgrounds who usually have trouble accessing diabetes technology.

What this trial studies

This pilot study aims to evaluate the feasibility of using hybrid closed-loop insulin pump therapy in a diverse group of adults with poorly controlled Type 1 Diabetes, specifically those with an HbA1c greater than 8.5%. The study will include 40 participants from various racial and ethnic backgrounds, focusing on those who have historically faced barriers to accessing diabetes technology. By expanding the participant pool beyond typical demographics, the researchers hope to identify facilitators and barriers to effective use of this technology. The study will take place in major health systems in the Los Angeles area, including UCLA and Harbor-UCLA Medical Center.

Who should consider this trial

Good fit: Ideal candidates are adults with Type 1 Diabetes, an HbA1c greater than 8.5%, who are not currently using an insulin pump and have medical insurance.

Not a fit: Patients with significant comorbidities affecting A1c accuracy, cognitive or physical impairments, or those with a limited life expectancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diabetes management and health outcomes for underserved populations with Type 1 Diabetes.

How similar studies have performed: While there have been studies on diabetes technology, this approach focusing on diverse and underserved populations is relatively novel.
