Study summary

The purpose of this follow-up study is to collect the outcome and safety of FTET cycles after the embryos are cryopreserved in P06029 (NCT01144416). P06029 was a study in which a single injection of corifollitropin alfa (SCH 900962) was compared with daily recombinant follicle stimulating hormone (recFSH) injections in women aged 35 to 42 years undergoing controlled ovarian stimulation (COS) prior to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

Study arms

  • Experimental
    Corifollitropin alfa 150 μg

    Participants in Base Study P06029 received a single injection of 150 ug corifollitropin alfa on Stimulation Day 1 and daily injections of placebo-recFSH from Stimulation Days 1 through 7. No medication or investigational product was administered in Follow-Up Study P06031.

    Biological: Corifollitropin alfa

  • Active comparator
    recFSH 300 IU

    Participants in the reference group in Base Study P06029 received a single injection of placebo for corifollitropin alfa on Stimulation Day 1 and daily injections of 300 IU recFSH on Stimulation Days 1 through 7. No medication or investigational product was administered in Follow-Up Study P06031.

    Biological: recFSH (follitropin beta)

What researchers measure

Primary outcomes

  1. Percentage of Participants With ≥1 Vital Pregnancy (Cumulative Vital Pregnancy Rate)

    The cumulative vital pregnancy rate was defined as the number of participants with at least 1 vital pregnancy in a controlled ovarian stimulation (COS) cycle in Base Study P06029 or a frozen-thawed embryo transfer (FTET) in Follow Up Study P06031, divided by the total number of participants in each Full Analysis Set (FAS) treatment group. A vital pregnancy was defined as an intrauterine pregnancy with fetal heart tones assessed at least 35 days (≥5 weeks) after embryo transfer (ET).

    Time frame: Assessed at least 35 days after ET in COS cycle in Base Study P06029 or an FTET cycle in Follow-Up Study P06031 (up to 2 years)

Secondary outcomes

  1. Percentage of Participants With ≥1 Live Birth (Cumulative Live-Birth Rate)

    The cumulative live-birth rate was defined as the number of participants with at least 1 live birth after ET in a COS cycle in Base Study P06029 or an FTET in Follow-Up Study P06031, divided by the total number of participants in each FAS treatment group.

    Time frame: From approximately 10 weeks after ET in Base Study P06029 or FTET in Follow-Up Study P06031 up to time of delivery (up to 2 years)
