Is this trial a fit for you?

Likely a good fit

Ideal participants are adults with type II diabetes requiring insulin, between 24 and 28 weeks of gestation, who can use a continuous glucose monitor and understand English.

Probably not a fit

Participants not meeting inclusion criteria or those with contraindications to insulin glargine or CGM may not benefit.

What this trial studies

This interventional Phase 4 trial randomizes adult pregnant participants with pregestational diabetes to receive either once-daily or twice-daily insulin glargine. Continuous glucose monitoring is used to track glucose levels and determine time in range. The goal is to see if split dosing improves glycemic control during the second and third trimesters. The study compares two regimens to identify potential differences in fetal and maternal glucose management.

Why it matters

Potential benefit: If successful, dosing twice daily could improve blood sugar control and potentially reduce complications related to diabetes in pregnancy.

How similar studies have gone: Previous work in diabetes management has explored dosing strategies; this study applies similar concepts specifically to pregnant patients with pregestational diabetes.
