Brief summary
This is a phase 1b clinical trial with Choriogonadotropin beta (FE999302) and Follitropin delta (Rekovelle). The trial is multicentre, randomized, partially double-blind, placebo-controlled, parallel-group investigating the effect of FE999302 on parameters influencing pregnancy rates in women undergoing controlled ovarian stimulation with a fixed dose of follitropin. The primary endpoint is the number of good-quality blastocysts on day 5 after oocyte retrieval. Secondary endpoints are number of follicles by size category and serum concentration of different hormones on stimulation day 6 and end-of stimulation, the number of stimulation days and oocytes retrieved, the number of metaphase II oocytes and fertilised oocytes, number of blastocysts on day 5, number of cryopreserved blastocysts, endometrial thickness at eos, positive bhcg rate, clinical pregnancy, vital pregnancy and ongoing pregnancy.
Interventions
The effect on parameters influencing pregnancy rates in women undergoing controlled ovarian stimulation with a fixed dose of follitropin.
To investigate the effect of FE 999302 on parameters influencing pregnancy rates in women undergoing controlled ovarian stimulation with a fixed dose of follitropin delta in a gonadotropin-releasing hormone (GnRH) antagonist protocol

Eligibility
Inclusion criteria
1. Subject informed consent form signed before any trial-related activities. 2. In good physical and mental health as judged by the investigator. 3. Serum anti-Müllerian hormone (AMH) levels of 15.0-35.0 pmol/L at screening (measured at central laboratory). 4. Pre-menopausal women between the ages of 18 and 40 years. The subjects must be at least 18 years (including the 18th birthday) and no more than 40 years (up to the day before the 41st birthday) when they sign the informed consent(s). 5. 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 (IVF) and/or intracytoplasmic sperm injection (ICSI) using fresh or frozen ejaculated sperm from male partner or sperm donor. 6. Infertility for at least 1 year before screening for subjects \<35 years or for at least 6 months for subjects ≥35 years (not applicable in case of tubal or severe male factor infertility). 7. No more than two controlled ovarian stimulation cycles initiated, regardless of outcome (taking
Exclusion criteria
2 and 3 into account) and the subject must be suitable for treatment with 10 or 15 µg/day follitropin delta (corresponding to 150 or 225 IU). 8. Regular menstrual cycles of 24-35 days (both inclusive), presumed to be ovulatory. 9. Early follicular phase (cycle day 2-5) serum levels of follicle-stimulating hormone (FSH) between 1 and 15 IU/L (measured at central laboratory). 10. Body mass index (BMI) between 18.0 and 30.0 kg/m2 (both inclusive) at screening.
