What this trial studies

This clinical trial aims to assess the effectiveness of Semaglutide and Empagliflozin, both individually and in combination, when added to Automated Insulin Delivery (AID) systems for improving time-in-range in adults with Type 1 Diabetes (T1D). The study employs a 2x2 factorial, randomized, placebo-controlled, double-blind, crossover design, allowing participants to receive all treatment combinations. The primary focus is to determine if the combination therapy enhances diabetes control compared to placebo and to evaluate the safety of these medications in this context.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 or older with a clinical diagnosis of Type 1 Diabetes for at least one year who have been using an Automated Insulin Delivery system for a minimum of three months.

Not a fit: Patients who have recently used GLP1-RA or SGLT2i medications, are pregnant or breastfeeding, or have severe renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve diabetes management and quality of life for patients with Type 1 Diabetes by increasing time-in-range.

How similar studies have performed: Other studies have shown promising results with similar combination therapies in diabetes management, indicating potential for success in this approach.
