Clinical Trial Summary

Clinical trial objective is to collect the outcome of Frozen-Thawed Embryo Transfer (FTET) cycles performed after the embryos are cryopreserved in the base study P05690 in order to estimate the cumulative pregnancy rate for each treatment group.

Description:

This is a follow-up protocol to collect the outcome of FTET cycles, performed after the embryos are cryopreserved in base study P05690 (NCT00702845), to enable estimation of the cumulative pregnancy rate for each treatment group.

Drug:
• corifollitropin alfa
Single injection of 100 µg corifollitropin alfa administered under protocol P05690

Biological:
• recFSH (follitropin alfa)
Daily recFSH administered under protocol P05690

Drug:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With an Ongoing Pregnancy (Cumulative Ongoing Pregnancy Rate)	Cumulative ongoing pregnancy rate was defined as 100 times the number of participants with an ongoing pregnancy either immediately after embryo transfer in base study P05690 (NCT00702845) or after one or more FTET cycles in follow up study P05711 following cryopreservation, divided by the total number of subjects that started treatment in base study P05690.	Up to 1 year after embryo transfer in base trial P05690 (NCT00702845), and FTET cycles in follow up study P05711
Secondary	Percentage of Participants in Follow up Study With a Miscarriage Per Clinical Pregnancy	Miscarriages were calculated per clinical pregnancy, defined as the presence of at least one gestational sac as assessed by USS or Doppler, or confirmed by live birth.	After one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)
Secondary	Percentage of Participants in Follow up Study With a Miscarriage Per Vital Pregnancy	Miscarriages were calculated per vital pregnancy, defined as the presence of at least one fetus with heart activity as assessed by USS or Doppler, or confirmed by live birth.	After one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)
Secondary	Percentage of Participants in Follow up Study With an Ecotopic Pregnancy	An ectopic pregnancy is where the embryo implants outside the uterus. Ectopic pregnancies were calculated per total number of participants started in FTET.	After one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)
Secondary	Percentage of Participants in Follow up Study With a Clinical Pregnancy	A clinical pregnancy is the presence of at least gestational sac or confirmed by live birth. Clinical pregnancies were calculated per attempt, meaning if any stage of in vitro fertilization (IVF) treatment was not achieved, zero values were imputed.	After one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)
Secondary	Percentage of Participants in Follow up Study With a Vital Pregnancy	A vital pregnancy is the presence of at least one fetus with heart activity. Vital pregnancies were calculated per attempt, meaning if any stage of IVF treatment was not achieved, zero values were imputed.	After one or more FTET cycles, assessed at least 10 weeks after embryo transfer (up to 1 year)
Secondary	Percentage of Participants With an Ongoing Pregnancy	An ongoing pregnancy is the presence of at least one fetus with heart activity at least 10 weeks after embryo transfer or confirmed at live birth. Ongoing pregnancies were calculated per attempt, meaning if any stage of IVF treatment was not achieved, zero values were imputed.	After one or more FTET, assessed at least 10 weeks after embryo transfer or at live birth (up to 1 year)
