Summary
This research study is being conducted at over 12 pregnancy research centers in the US. The
study will compare an investigational treatment with a placebo (a treatment without
medication). Neither the investigators nor the patients in the trial will know which
treatment has been assigned. All study medications will be given vaginally once a day.
Treatment will begin before pregnancy week 23 and will continue until the end of pregnancy
week 36.
