Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Cumulative Ongoing Pregnancy Rate After the Fresh Cycle and Cryopreserved Cycles Initiated Within 12 Months From the Start of COS | 8-9 weeks after transfer (up to approximately 16 months after start of stimulation) | Defined as at least one intrauterine viable fetus 8-9 weeks after transfer. Data in this endpoint are presented for the fresh cycle and the cryopreserved cycles. |
| Secondary | Ongoing Pregnancy Rate in the Fresh Cycle and in the Cryopreserved Cycles | 8-9 weeks after transfer (up to approximately 16 months after start of stimulation) | Defined as at least one intrauterine viable fetus 8-9 weeks after transfer. Data in this endpoint are presented for the fresh cycle and the cryopreserved cycles. |
| Secondary | Time From Start of COS to Ongoing Pregnancy Across the Fresh and Cryopreserved Cycles | 8-9 weeks after transfer (up to approximately 16 months after start of stimulation) | Time from start of COS to ongoing pregnancy, including both the fresh and cryopreserved cycles. In the placebo group, no participants achieved an ongoing pregnancy either after 12 calendar months or after 12 study months. |
| Secondary | Time From Start of COS to Ongoing Pregnancy Across the Fresh and Cryopreserved Cycles, Measured in Number of Cycles Before Achieving Ongoing Pregnancy | 8-9 weeks after transfer (up to approximately 16 months after start of stimulation) | Time from start of COS to ongoing pregnancy, including both the fresh and cryopreserved cycles, measured in number of cycles before achieving ongoing pregnancy. In the placebo group, no participants achieved an ongoing pregnancy either after 12 calendar months or after 12 study months. |
| Secondary | Ongoing Implantation Rate in the Fresh Cycle, the Cryopreserved Cycles and Cumulatively | 8-9 weeks after transfer (up to approximately 16 months after start of stimulation) | Defined as the number of intrauterine viable fetuses 8-9 weeks after transfer divided by number of blastocysts transferred. Data in this endpoint are presented for the fresh cycle, the cryopreserved cycles, and all cycles. One participant can contribute with a range from zero to multiple blastocysts. Data is not shown for placebo arm because no blastocyst transfer was performed in the fresh cycle or cryopreserved cycles. '%' in the unit of measure refers to 'percentage'. |
| Secondary | Clinical Pregnancy Rate in the Fresh Cycle, the Cryopreserved Cycles and Cumulatively | 5-6 weeks after transfer (up to approximately 15 months after start of stimulation) | Defined at least one gestational sac 5-6 weeks after transfer. Data in this endpoint are presented for the fresh cycle, the cryopreserved cycles, and all cycles. |
| Secondary | Vital Pregnancy Rate in the Fresh Cycle, the Cryopreserved Cycles and Cumulatively | 5-6 weeks after transfer (up to approximately 15 months after start of stimulation) | Defined at least one intrauterine gestational sac with fetal heart beat 5-6 weeks after transfer. Data in this endpoint are presented for the fresh cycle, the cryopreserved cycles, and all cycles. |
| Secondary | Implantation Rate in the Fresh Cycle, the Cryopreserved Cycles and Cumulatively | 5-6 weeks after transfer (up to approximately 15 months after start of stimulation) | Defined as the number of gestational sacs 5-6 weeks after transfer divided by number of blastocysts transferred. Data in this endpoint are presented for the fresh cycle, the cryopreserved cycles, and all cycles. One participant can contribute with a range from zero to multiple blastocysts. Data is not shown for placebo arm because no subjects underwent blastocyst transfer in the fresh cycle or cryopreserved cycles. '%' in the unit of measure refers to 'percentage'. |
| Secondary | Positive Beta Human Chorionic Gonadotropin (βhCG) Rate in the Fresh Cycle, the Cryopreserved Cycles and Cumulatively | 10-14 days after transfer (up to approximately 14 months after start of stimulation) | Defined as positive serum βhCG test 10-14 days after transfer. Data in this endpoint are presented for the fresh cycle, the cryopreserved cycles, and all cycles. |
| Secondary | Proportion of Subjects in the Fresh Cycle With Triggering of Final Follicular Maturation (hCG, With GnRH Agonist, and in Total), Cycle Cancellation and Transfer Cancellation | Up to 5 days after oocyte retrieval (up to 27 days after start of stimulation) | Data in this endpoint are presented for the fresh cycle. |
