Official title: Induction of Labor in Morbidly Obese Patients: Comparison of 50 mcg and 25 mcg Misoprostol - A Randomized Control Trial

Run by University of Maryland, Baltimore · NCT06199154 · Data updated 2026-11-12

This study is testing whether two different doses of Misoprostol can help morbidly obese women have a vaginal delivery instead of a cesarean section when inducing labor.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are morbidly obese pregnant women (BMI ≥ 40) who are at least 18 years old and scheduled for induction of labor after 34 weeks of gestation.

Probably not a fit

Patients with a history of cesarean delivery or contraindications to vaginal delivery will not benefit from this study.

What this trial studies

This randomized controlled trial aims to compare the effectiveness of two different doses of Misoprostol (25 mcg vs 50 mcg) for inducing labor in morbidly obese patients with a BMI greater than 40. The study focuses on patients scheduled for induction of labor after 34 weeks of gestation, assessing their ability to achieve vaginal delivery and reduce the need for cesarean delivery. Participants will be randomly assigned to receive one of the two doses of Misoprostol every four hours, with the goal of improving delivery outcomes in this high-risk population.

Why it matters

Potential benefit: If successful, this study could lead to improved rates of vaginal delivery and reduced surgical complications for morbidly obese patients during labor.

How similar studies have gone: While there is limited research specifically on Misoprostol dosing in morbidly obese patients, similar studies have shown that optimizing labor induction methods can improve delivery outcomes.
