Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with type 1 diabetes who are prescribed GLP-1RA or SGLT inhibitors as part of usual care and use CGM with available data.

Probably not a fit

Patients not using GLP-1RA or SGLT inhibitors as part of usual care or without CGM data may not experience the potential benefits studied.

What this trial studies

This multicenter, registry-based study will observe adults with type 1 diabetes who are already prescribed GLP-1RA or SGLT inhibitors in addition to insulin. Data from patients using continuous glucose monitoring will be collected for at least one month before enrollment and throughout the study to evaluate safety and potential efficacy. The analysis will focus on real-world outcomes, including glycemic control and adverse events, in a non-interventional setting. Leading institutions in Indiana, California, and Florida will collaborate with the Jaeb Center to aggregate data across sites. The study does not specify a formal intervention beyond usual care adjunct therapies.

Why it matters

Potential benefit: If successful, findings could inform how GLP-1RA or SGLTi adjuncts to insulin might improve diabetes management for some adults with type 1 diabetes.

How similar studies have gone: Previous observational work has explored adjunctive therapies in type 1 diabetes, but randomized evidence remains limited, making this registry a relatively novel data source.
