Using closed-loop insulin delivery to achieve remission of type 2 diabetes

Targeting Beta-cell Function to Achieve Remission of Type 2 Diabetes (REACTIVATE). An Open-label, Single-centre, Randomised, Parallel Study to Assess the Efficacy, Safety and Utility of Fully Closed-loop Insulin Delivery in Achieving Remission of Diabetes Compared to Standard Therapy With a Glucose Sensor in Adults With Recent Onset Type 2 Diabetes

Not applicable Interventional University of Cambridge · NCT06844539

This study tests if a new insulin delivery system, along with diet and lifestyle changes, can help adults with early type 2 diabetes go into remission and stop needing diabetes medications.

What this trial studies

This study investigates whether intensive insulin therapy using closed-loop technology, combined with diet and lifestyle education, can restore beta-cell function and achieve remission in adults with recent-onset type 2 diabetes. It is a single-centre, open-label, randomised, parallel design study comparing 12 weeks of closed-loop insulin delivery to standard care with a glucose sensor. The primary outcome is the number of participants achieving diabetes remission at 52 weeks, defined as HbA1c below 48mmol/mol after 12 weeks off all diabetes medications. Participants will also undergo mixed meal tolerance tests to assess key metabolic outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 years and older with recent-onset type 2 diabetes diagnosed within the last 6 months to 5 years.

Not a fit: Patients with type 1 diabetes or those currently using insulin pumps or closed-loop systems will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to a significant improvement in diabetes management and potentially allow some patients to achieve remission.

How similar studies have performed: Other studies have shown promise with similar closed-loop insulin delivery approaches, indicating potential for success in this novel application.
