NCT Number: NCT00308711
The purpose of this study is to determine whether the misoprostol vaginal insert (50 mcg and 100 mcg) can safely and effectively speed time to vaginal delivery compared to Cervidil (R) in women who need to have cervical ripneing and induction of labor.

Induction of labor is required in approximately 20% of pregnant women. Although contractions can be brought on by oxytocin ("pitocin"), some women need help in softening the cervix, or mouth of the womb (uterus), before oxytocin can be started. Prostaglandins have been shown to ripen, or soften, the cervix; at present, the only prostaglandin approved for marketing by FDA for this purpose is dinoprostone. Dinoprostone can be delivered in several ways; one method is to use a polymer vaginal insert that slowly releases the dinoprostone directly to the cervical tissues. This product is called Cervidil (R) and has been marketed for more than 10 years in the United States. Misoprostol is another form of prostaglandin that is approved for protecting the stomach and intestinal lining for patients taking NSAIDs. Misoprostol has also been used by many obstetricians for cervical ripening and inducing contractions, but, it is not approved by FDA for this purpose.
The same company that makes the Cervidil polymer insert has made an insert that will slowly release misoprostol. This study will determine whether this investigational insert containing misoprostol will decrease time to vaginal delivery compared to Cervidil. Two different doses of misoprostol will be tested (50 micrograms and 100 micrograms); each vaginal insert will gradually release a small, controlled amount of misoprostol over up to 24 hours.
Comparator: The Cervidil (R) vaginal insert containing dinoprostone will be the comparator in this study.

Inclusion criteria
Exclusion criteria
Hydrogel polymer intravaginal insert with retrieval system. One insert is to remain in the posterior fornix of the vagina until removed for one of the following conditions: onset of active labor; maternal/fetal complication, e.g. non-reassuring fetal heart rate. Record if the insert falls out prior to meeting one of the first two criteria. In no case is the insert to remain in place longer than 24h.
Other names: Misopess(TM)
Hydrogel polymer intravaginal insert with retrieval system. One insert is to remain in the posterior fornix of the vagina until removed for one of the following conditions: onset of active labor; maternal/fetal complication, e.g. non-reassuring fetal heart rate. Record if the insert falls out prior to meeting one of the first two criteria. In no case is the insert to remain in place longer than 24h.
Other names: Misopess(TM)
Hydrogel polymer intravaginal insert with retrieval system. One insert is to remain in the posterior fornix of the vagina until removed for one of the following conditions: onset of active labor; maternal/fetal complication, e.g. non-reassuring fetal heart rate. Record if the insert falls out prior to meeting one of the first two criteria. In no case is the insert to remain in place longer than 24h.
Other names: Propess(R), 10 mg dinoprostone vaginal insert
Time frame: 2880 minutes
Interval between time/date of insertion of study drug and time/date of neonate birth. This is a time-to-event analysis, there is no set time for the assessment. The endpoint occurs when the baby is born. 48 hours can be used as an approximate interval by which time most of the babies have been delivered.
Time frame: 2880 minutes
Percentage of participants with cesarean delivery after study drug was administered. There is no set assessment time or date as the woman's labor may last hours or days.
Time frame: 96 hours
This outcome reports the percentage of adverse events in each treatment arm spontaneously reported or observed during the study. The intrapartum period (mother is still pregnant) is called the "Maternal/Fetal" period; once the baby has been born, adverse events are assessed separately for the mother (Post Partum) and the baby (Neonatal). The number of adverse events was assessed separately for each of the three periods.
Time frame: 2880 minutes
Incidence in each treatment group of need for oxytocin for pre-delivery induction or augmentation of labor.
Time frame: 12 hours
Measured the percentage of participants who achieved success on the mBS. This composite score is based on the mBS and vaginal delivery and it is measured 12 hours after insertion of the study drug. The mBS has a score of 0 when the cervix is not ripe and a score of 12 when completely ripened. The 12 hour score is compared to baseline. Using the mBS, assess at 12 hours whether each subject has met any of the following three criteria: 1) has improved (increased) the mBS by at least 3 points from baseline; 2) has reached a score of at least 6 on the mBS; or 3) has acheived a vaginal delivery.
Time frame: 2880 minutes
Interval from insertion of study drug to onset of active labor, defined as at least three contractions in a ten-minute period of at least moderate intensity and resulting in cervical change such as dilatation or effacement; OR at least 4 cm cervical dilatation achieved after progressive change in dilatation.
Time frame: 2880 minutes
Interval from study drug insertion to ROM.
Time frame: 5760 minuts
Minutes in Labor and Delivery (L & D) suite starting from insertion of the study drug to discharge from L & D to post partum care.
Time frame: 10 days
Duration of stay in hospital for mother and neonate starting with insertion of the study drug and ending with discharge from the hospital.
