Brief Summary

The primary objective of this study is to confirm the efficacy of a single oral 900 mg dose of nolasiban versus placebo to increase the ongoing clinical pregnancy rate at 10 weeks post-embryo transfer (ET) day.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

The study is a prospective, randomised, parallel group, double-blind, placebo-controlled, Phase 3 study to confirm the efficacy and the safety of nolasiban versus placebo to increase pregnancy and live birth rates in 820 women undergoing fresh single blastocyst transfer following in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI).

Outcome Measures

Primary Outcome Measures

  1. Ongoing pregnancy with fetal heart beat at 10 weeks [10 weeks post ET day]

    Ongoing pregnancy defined as an intra-uterine pregnancy with fetal heart beat at 10 weeks post embryo transfer day

Secondary Outcome Measures

  1. Live birth [24 to 40 weeks of gestation]

    Live birth after 24 weeks of gestation

  2. Clinical pregnancy at 6 weeks post ET day [6 weeks post ET]

    Clinical pregnancy defined as intra-uterine pregnancy with fetal heart beat at 6 weeks post-ET day

  3. Pregnancy rate at 14 days post Oocyte Pick-up (OPU) [14 days post OPU]

    Positive blood pregnancy test at 14 days post OPU day

  4. Pregnancy loss [6 weeks post ET to 24 weeks gestation]

    Pregnancy loss at 6 or 10 weeks after ET and before 24 weeks of gestation

  5. Plasma concentrations of nolasiban [3.5 hours, 5 hours and at 7 hours (latest 72 hours) after nolasiban administration]

    Plasma concentrations of nolasiban after administration

Other Outcome Measures

  1. Adverse events [Through study completion, up to 11 months]

    Treatment emergent adverse events frequency and severity

  2. Neonatal assessments [Birth of infant until 28 days]

    Incidence of any malformation or any significant morbidity during the neonatal period

  3. Ages and Stages Questionnaires® (ASQ-3™) 6 and 12 month Questionnaire [6 and 12 months after term]

    Screening questionnaire composed of 30 questions completed by the parent. Questions are divided into five areas: communication, gross motor, fine motor, problem solving and personal-social. Parents respond yes, sometimes and not yet to questions, these are converted to points 10, 5 and 0 for scoring and are totalled for each developmental area. These 5 area scores are compared with empirically derived cutoff points.
