Study summary

The purpose of this study is to assess the safety and efficacy of rhRlx for cervical ripening, when compared to a placebo.

Read the detailed description

A multicenter, randomized, double-blind, placebo-controlled, dose escalation study of healthy female subjects at ≥ 40 weeks gestation and who are scheduled for induction. A dose-escalation portion of the study is followed by a randomized, double-blind, placebo-controlled portion of the study. The endpoints include cervical ripening, as well as progression to labor and delivery.
