Continuous glucose monitoring versus finger‑stick checks in pregnancy with type 2 diabetes

Maternal Continuous Glucose Monitoring Surveillance Compared to Finger-stick Glucose Monitoring in Pregnancies With Type 2 Pregestational Diabetes

Not applicable Interventional Thomas Jefferson University · NCT07184775

This trial tests whether wearing a continuous glucose monitor helps pregnant people with type 2 diabetes keep up with blood sugar checks more than traditional finger‑stick testing.

What this trial studies

This randomized trial assigns pregnant people with pregestational type 2 diabetes to either standard finger‑stick glucose monitoring or to wearing a continuous glucose monitor during pregnancy. The main goal is to compare adherence to glucose monitoring between the two methods, with secondary analyses of maternal glycemic control and neonatal outcomes. Eligible participants are those with singleton pregnancies without fetal anomalies who begin prenatal care before 20 weeks; people with type 1 diabetes, insulin allergy, or inability to wear a CGM are excluded. Medication adjustments follow routine clinical care based on the glucose data collected from the assigned monitoring method.

Who should consider this trial

Good fit: Ideal candidates are pregnant people with singleton pregnancies and pregestational type 2 diabetes who start prenatal care before 20 weeks and can wear a continuous glucose monitor.

Not a fit: People with type 1 diabetes, those allergic to insulin, or those unable or unwilling to wear a CGM are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, CGMs could make it easier to track blood sugar during pregnancy and lead to better glucose control and healthier newborn outcomes.

How similar studies have performed: Previous studies in pregnancy and other diabetes populations have shown CGMs increase monitoring adherence and improve glycemic control, but randomized evidence specifically in pregestational T2DM pregnancies is limited.
