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.

Condition or Disease Intervention/Treatment Phase
  • Drug: OBE001 dose 1
  • Drug: OBE001 dose 2
  • Drug: OBE001 dose 3
  • Drug: 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

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

    Percentage of women with an intra-uterine pregnancy with positive embryo heart-beat at about 6 weeks post ET day.

Secondary Outcome Measures

  1. EFFICACY ENDPOINTS Percentage of women with positive blood pregnancy test [14 days post OPU day]

    Percentage of women with positive blood pregnancy test at 14 days post OPU day.

  2. EFFICACY ENDPOINTS Percentage of women with an intra-uterine pregnancy with positive embryo heart-beat [10 weeks post OPU day]

    Percentage of women with an intra-uterine pregnancy with positive embryo heart-beat at 10 weeks post OPU day.

  3. 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

  4. EFFICACY ENDPOINTS Change from baseline to the time of ET in the rate of uterine contractions [at 3.5 hours after dose administration]

    Change from baseline to the time of ET in the rate of uterine contractions (UC/min).

Other Outcome Measures

  1. SAFETY ENDPOINTS Treatment emergent adverse events frequency and severity [up to 10 weeks post OPU day]

    Treatment emergent adverse events frequency and severity

  2. SAFETY ENDPOINTS (Haematology and biochemistry assessments) [14 days post OPU day]

    Haematology and biochemistry assessments at screening and at visit V3 (14 days post OPU day)

  3. PHARMACOKINETIC ENDPOINTS Plasma levels of OBE001 [at 3.5 hours after dose administration]

    Plasma levels of OBE001

  4. 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
