The primary objective of this study is to assess the increase in clinical pregnancy rate after administration of a range of single oral doses of OBE001, an oral oxytocin antagonist, compared to placebo.
The study is a prospective, dose-finding, randomised, parallel group, double-blind, placebo-controlled study investigating the efficacy and the safety of the oxytocin receptor antagonist OBE001 in 240 women undergoing embryo transfer following IVF or ICSI.

The four-arm study (OBE001 dose 1, dose 2, dose 3, and placebo) design will allow evaluation of a possible dose-dependent pattern of action of OBE001 and, simultaneously, comparison of active compound with placebo with regard to both efficacy and safety.
