Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include reproductive-aged women with type 1 diabetes who have regular menstrual cycles and are using the Medtronic Minimed 780G closed-loop system.
✕Probably not a fit
Patients who are pregnant, using hormonal contraceptives, or have serious health conditions may not benefit from this study.

What this trial studies
This observational study aims to evaluate how automatic insulin infusion responds to changes in insulin sensitivity across different phases of the menstrual cycle in reproductive-aged women with type 1 diabetes. Utilizing an advanced closed-loop system, the study seeks to identify both the limitations and effectiveness of this technology in managing glycemic control. Insights gained will inform improvements in control algorithms and learning strategies within closed-loop systems, addressing unique challenges faced by women in diabetes management.
Why it matters
Potential benefit: If successful, this study could enhance insulin management for women with type 1 diabetes, leading to better glycemic control during their menstrual cycles.
How similar studies have gone: While there is ongoing research in diabetes management, this specific focus on menstrual cycle effects in women using closed-loop systems is relatively novel.
