IMPLANT: OBE001 Phase 2 Dose-finding Study Versus Placebo in Women Undergoing Embryo Transfer in the Context of IVF-ICSI
Study Details
Study Description
Brief Summary
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.

Phase 2 |
Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- EFFICACY ENDPOINTS Percentage of women with an intra-uterine pregnancy with positive embryo heart-beat [about 6 weeks post ET day]

Secondary Outcome Measures
- EFFICACY ENDPOINTS Percentage of women with positive blood pregnancy test [14 days post OPU day]

Percentage of women with an intra-uterine pregnancy with positive embryo heart-beat at 10 weeks post OPU day.
- EFFICACY ENDPOINTS The embryo-implantation rate [6 weeks post ET day]
The embryo-implantation rate defined as the number of intra-uterine embryos with positive heart-beat at 6 weeks post ET day divided by the number of embryos transferred
- EFFICACY ENDPOINTS Change from baseline to the time of ET in the rate of uterine contractions [at 3.5 hours after dose administration]

- PHARMACOKINETIC ENDPOINTS Plasma levels of OBE001 [at 3.5 hours after dose administration]
Plasma levels of OBE001
- PHARMACOKINETIC-PHARMACODYNAMIC ENDPOINTS :Uterine contractions relationship to OBE001 plasma levels and pregnancy rate [up 10 weeks post OPU day]
Uterine contractions relationship to OBE001 plasma levels and pregnancy rate
