Overview
Brief Summary
The purpose of this phase 2 dose-ranging trial is to investigate the effects of FE 999302 on parameters influencing pregnancy rates in women undergoing Controlled Ovarian Stimulation (COS) with follitropin delta in a long gonadotropin releasing hormone (GnRH) agonist protocol.
Furthermore, the study intends:
- To investigate the safety of FE 999302 in women undergoing COS with follitropin delta in a long GnRH agonist protocol.
- To investigate the potential immunogenicity of FE 999302 in subjects undergoing COS with follitropin delta in a long GnRH agonist protocol.
- To estimate the impact of body weight on FE 999302 exposure in subjects undergoing COS with follitropin delta in a long GnRH agonist protocol.

Eligibility Criteria
Inclusion Criteria
- •Informed consent documents signed prior to screening evaluations.
- •In good physical and mental health as judged by the investigator.
- •Anti-Müllerian hormone (AMH) levels at screening of 5.0-35.0 pmol/L (as measured by Elecsys® AMH Plus Immunoassay \[Roche Diagnostics\] at central laboratory).
- •Pre-menopausal women between the ages of 30 and 42 years. The subjects must be at least 30 years (including the 30th birthday) and no more than 42 years (up to the day before the 43rd birthday) when they sign the informed consent.
- •Infertile women diagnosed with tubal infertility, unexplained infertility, endometriosis stage I/II or with partners diagnosed with male factor infertility, eligible for in vitro fertilisation and/or intracytoplasmic sperm injection using fresh or frozen ejaculated sperm from male partner or sperm donor.
- •Infertility for at least 1 year before screening for subjects less than 35 years or for at least 6 months for subjects greater than equal to (≥)35 years (not applicable in case of tubal or severe male factor infertility).
Exclusion Criteria
- •Known polycystic ovary syndrome (PCOS) associated with anovulation or known endometriosis stage III-IV (defined by the revised American Society for Reproductive Medicine \[ASRM\] classification, 1996).
- •One or more follicles ≥10 mm (including cysts) observed on the transvaginal ultrasound after down-regulation prior to randomisation on stimulation day 1 (puncture of cysts is allowed prior to randomisation).
- •Pregnancy (negative pregnancy tests must be documented at screening and prior to start of down-regulation) or contraindication to pregnancy.

Outcomes
Primary Outcomes
Number of good-quality blastocysts on Day 5 after oocyte retrieval
Time Frame: On Day 5 after oocyte retrieval
Quality of blastocysts was assessed by blastocyst expansion and hatching status, blastocyst inner cell mass grading, and trophectoderm grading. The scoring was based on the classification system by Gardner and Schoolcraft, with additional categories for inner cell mass (degenerative or no inner cell mass) and trophectoderm (degenerative or very large cell).
Secondary Outcomes
- Total number of stimulation days(At end-of-stimulation (up to 20 stimulation days))
- Clinical pregnancy rate(5-6 weeks after blastocyst transfer)
- Number of fertilised 2 pronuclei (2PN) oocytes(On day 1 after insemination)
- Number and size of follicles on stimulation Day 6(On stimulation Day 6)
- Total gonadotropin dose(At end-of-stimulation (up to 20 stimulation days))
- Incidence and intensity of injection site reactions after FE 999302 administration (redness, pain, itching, swelling and bruising) assessed by the subject during the stimulation period(Immediately after injection of FE 999302 or placebo, 30 minutes after injection, and 24 hours after injection)

- Number and size of follicles at end-of-stimulation(At end-of-stimulation (up to 20 stimulation days))
- Number of oocytes retrieved(On the day of oocyte retrieval)
