About Gestational Diabetes
Gestational diabetes develops during pregnancy when the body cannot make enough insulin to meet the extra needs. It can increase risks for both mother and baby if not managed. Treatment includes blood sugar monitoring, dietary changes, exercise, and sometimes insulin.
Clinical trials are advancing new treatments for gestational diabetes. Currently, 35 studies are recruiting a combined 12,726 participants across the United States. Research is being conducted by 20 organizations including Jaeb Center for Health Research, Ohio State University, Indiana University and 17 others.

CGM for the Early Detection and Management of Hyperglycemia in Pregnancy
The goal of this clinical trial is to use continuous glucose monitoring (CGM) to quickly detect and manage high blood sugar in pregnant women, early in pregnancy. The main questions it aims to answer are: (1) any problems for the baby, such as being too large for their age, shoulder injuries (like broken bones), high bilirubin levels needing light treatment, low blood sugar, or needing to stay in...
DECIDE: A Comparative Effectiveness Trial of Metformin Versus Insulin for the Treatment of Gestational Diabetes
This is a non-inferiority patient-centered and pragmatic comparative-effectiveness pregnancy randomized controlled trial (RCT) with postpartum maternal and child follow-up through 2 years of 1,572 individuals with gestational diabetes mellitus (GDM) randomized to oral metformin versus injectable insulin. This study will determine if metformin is not inferior to insulin in reducing adverse pregnan...
