- Regular menstrual cycles of 24-35 days (both inclusive).
- Hysterosalpingography, hysteroscopy or saline infusion sonography, documenting a uterus consistent with expected normal function (e.g. no evidence of clinically interfering uterine fibroids defined as submucous fibroids of any size or intramural fibroids larger than 3 cm in diameter, no polyps and no congenital structural abnormalities which are associated with a reduced chance of pregnancy) at screening or within 1 year prior to screening.
- Transvaginal ultrasound documenting presence and adequate visualization of both ovaries, without evidence of significant abnormality (e.g. enlarged ovaries which would contraindicate the use of gonadotropins) and normal adnexa (e.g. no hydrosalpinx) at screening. Both ovaries must be accessible for oocyte retrieval.
- Early follicular phase (cycle day 2-4) serum levels of FSH between 1 and 15 IU/L (results obtained within 3 months prior to randomization).

Exclusion Criteria:

In case partner sperm will be used and the sperm production is severely impaired (concentration less than 1 million/mL), normal karyotype, including no Y-chromosome microdeletion, must be documented.
- Any known clinically significant systemic disease (e.g. insulin-dependent diabetes).
- Known inherited or acquired thrombophilia.
- Active arterial or venous thromboembolism or severe thrombophlebitis, or a history of these events.
- Any known endocrine or metabolic abnormalities (pituitary, adrenal, pancreas, liver or kidney) with the exception of pharmacologically controlled sub-clinical hypothyroidism.
- Known tumors of the ovary, breast, uterus, adrenal gland, pituitary or hypothalamus which would contraindicate the use of gonadotropins.
- Known moderate or severe impairment of renal or hepatic function.
- Any abnormal finding of clinical chemistry, hematology, thyroid-stimulating hormone (TSH) or prolactin, or vital signs at screening, which is judged clinically significant by the investigator.
- Known abnormal cervical cytology of clinical significance observed within three years prior to randomization (unless the clinical significance has been resolved).
- Findings at the gynecological examination at screening which preclude gonadotropin stimulation or are associated with a reduced chance of pregnancy, e.g. congenital uterine abnormalities or retained intrauterine device.

- Known current active pelvic inflammatory disease.
- Use of fertility modifiers during the last menstrual cycle before randomization, including dehydroepiandrosterone (DHEA), metformin or cycle programming with oral contraceptives, progestogen or estrogen preparations.

Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
|
Placebo was administered as single daily subcutaneous injection dialed to the same value (dose) as FE 999049. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early OHSS with the exception of GnRH agonist for triggering of final follicular maturation, was not allowed. |
Experimental: FE 999049 (Follitropin Delta)
|
FE 999049 was administered as single daily subcutaneous injections in the abdomen at a starting dose of 15 μg daily that was fixed for the first four stimulation days. Based on ovarian response, the dose could be adjusted by 3 μg, with dose increases implemented not more frequently than once every 2 days and dose decreases implemented per investigator's judgement. The minimum daily dose was 6 μg, and the maximum daily dose was 24 μg. Participants could be treated for a maximum of 20 days. Coasting, use of dopamine agonist or any other drug to prevent early ovarian hyperstimulation syndrome (OHSS) with the exception of gonadotropin-releasing hormone (GnRH) agonist for triggering of final follicular maturation, was not allowed

The percentage of participants with biochemical pregnancy, spontaneous abortion, ectopic pregnancy (with and without medical/surgical intervention) and vanishing twins in the fresh cycle are presented. Data represents participants with positive βhCG. Data is not shown for placebo arm because no participants had a positive βhCG. '%' in the unit of measure refers to 'percentage'. Unit: % of participants with early pregnancy loss. |
