What this trial studies

This multicenter randomized clinical trial involves 828 overweight and obese pregnant women diagnosed with gestational diabetes. The study aims to compare the effects of intensive glycemic targets against standard glycemic targets on perinatal outcomes. Participants will be monitored throughout their pregnancy to assess the impact of these glycemic control strategies on complications associated with gestational diabetes. The trial is conducted across four medical centers in the U.S. with high obesity rates, ensuring a diverse participant pool.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 18-45 with a singleton gestation and diagnosed with gestational diabetes while being overweight or obese.

Not a fit: Patients with significant fetal anomalies or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pregnancy outcomes for overweight and obese women with gestational diabetes.

How similar studies have performed: Previous studies have shown promising results with intensive glycemic control in similar populations, suggesting potential for success in this trial.
