Are You a Good Fit for This Trial?

The PROMMO Trial is for pregnant women over 18 with a single baby, between 34 and less than 42 weeks along, who have had their water break before labor starts and an unfavorable cervix for delivery. Women must not have had a previous C-section, bleeding disorders like von Willebrand's or hemophilia, recent anticoagulants use, or infection concerns.

Inclusion Criteria

Early Term to late term pregnancy (>37 weeks and 0 days and <42 weeks and 0 days)

Confirmed rupture of membranes by either sterile speculum exam or AmniSure

I am in my late preterm pregnancy stage (34-36 weeks).

Exclusion Criteria

The pregnancy cannot be accurately dated.

There is a worry about an infection inside the womb.

I received blood thinners within a day after giving birth.

What Are the Treatments Tested in This Trial?

Interventions

• Intravenous Oxytocin
• Misoprostol Oral Product

Trial Overview This study compares two ways to start labor when the water breaks early: swallowing Misoprostol pills versus getting Oxytocin through an IV. It aims to find out which method works best for women with a low Bishop score indicating the cervix isn't ready for birth.

How Is the Trial Designed?

Group I: intravenous oxytocin Active Control 1 Intervention

At time of delivery, participants randomly assigned to intravenous oxytocin, will be administered the drug per standard of labor and delivery titrations.

Group II: oral misoprostol Active Control 1 Intervention

At time of delivery, participants randomly assigned to either oral misoprostol will receive 50 mcg of Misoprostol every 4 hours up to 6 doses, OR until simplified Bishop score \>6 (whichever is achieved first).
