Comparing insulin pump therapy to multiple daily insulin injections for young adults with type 1 diabetes

Official title: Effects of Insulin Pump Versus Multiple Daily Injections of Insulin on Glycemic and Metabolic Control in Type 1 Diabetic Patients Transitioned to the Adult Center: the Management and Technology for Transition Study (METRO)

Run by University of Campania Luigi Vanvitelli · NCT03463564 · Data updated 2026-11-12

This study tests whether using an insulin pump works better than daily insulin shots for young adults with type 1 diabetes who have trouble controlling their blood sugar.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are young adults with type 1 diabetes for at least 12 months, experiencing persistent high HbA1c levels and significant glucose variability.

Probably not a fit

Patients who have previously used an insulin pump or have severe chronic diseases may not benefit from this study.

What this trial studies

This study evaluates the effects of continuous subcutaneous insulin infusion (CSII) therapy compared to multiple daily injections (MDI) on glycemic and metabolic control in young adults transitioning from pediatric to adult diabetes care. It targets individuals with type 1 diabetes who have struggled to maintain glycemic control despite optimized education and therapy. The study aims to determine which method of insulin delivery is more effective in managing blood sugar levels and reducing variability during this critical transition phase.

Why it matters

Potential benefit: If successful, this study could provide insights into the most effective insulin delivery method for improving glycemic control in young adults with type 1 diabetes.

How similar studies have gone: While insulin pump therapy and multiple daily injections are both established methods for managing type 1 diabetes, this specific comparison during the transition phase has not been extensively studied, making it a novel approach.
