Recruitment & Eligibility

Status: COMPLETED

Sex: Female

Target Recruitment: 373

Inclusion Criteria

Informed Consent Documents signed prior to any trial-related procedures.
In good physical and mental health.
Japanese females between the ages of 20 and 40 years.
Infertile women diagnosed with tubal infertility, unexplained infertility, endometriosis stage I/II (defined by the revised American Society for Reproductive Medicine (ASRM) classification) or with partners diagnosed with male factor infertility, eligible for in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI) treatment using ejaculated sperm from male partner.
Infertility for at least 1 year before randomization (not applicable in case of tubal or severe male factor infertility).
The trial cycle will be the participant's first controlled ovarian stimulation cycle for IVF/ICSI.
Hysterosalpingography, hysteroscopy, saline infusion sonography or transvaginal ultrasound documenting a uterus consistent with expected normal function (e.g. no evidence of clinically interfering uterine fibroids defined as submucous 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) within 1 year prior to screening. This also includes women who have been diagnosed with any of the above medical conditions but have had them surgically corrected within 1 year prior to screening.
Transvaginal ultrasound documenting presence and adequate visualization of both ovaries, without evidence of significant abnormality (e.g. no endometrioma greater than 3 cm or enlarged ovaries which would contraindicate the use of gonadotropins) and fallopian tubes and surrounding tissue without evidence of significant abnormality (e.g. no hydrosalpinx) within 1 year prior to screening. Both ovaries must be accessible for oocyte retrieval.
Early follicular phase (cycle day 2-4) serum levels of follicle stimulating hormone (FSH) between 1 and 15 IU/L (results obtained within 3 months prior to screening).
Body mass index (BMI) between 17.5 and 32.0 kg/m^2 (both inclusive) at screening.

Exclusion Criteria

Known endometriosis stage III-IV (defined by the revised ASRM classification).
One or more follicles >10 mm (including cysts) observed on the transvaginal ultrasound prior to start of stimulation on stimulation day 1 (puncture of cysts prior randomization is allowed).
Known history of recurrent miscarriage (defined as three consecutive losses after ultrasound confirmation of pregnancy (excl. ectopic pregnancy) and before week 24 of pregnancy).
Known abnormal karyotype of participant or of her partner. In case the sperm production is severely impaired (concentration <1 million/mL), normal karyotype, including no Y chromosome microdeletion, must be documented.
Active arterial or venous thromboembolism or severe thrombophlebitis, or a history of these events.
Any known clinically significant systemic disease (e.g. insulin-dependent diabetes).
Any known endocrine or metabolic abnormalities (pituitary, adrenal, pancreas, liver or kidney) which can compromise participation in the trial with the exception of controlled thyroid function disease.
Known tumours of the ovary, breast, uterus, adrenal gland, pituitary or hypothalamus which would contraindicate the use of gonadotropins.

Arm && Interventions

Group	Intervention	Description
Follitropin delta	Follitropin delta	FE 999049 was administered as single daily subcutaneous injections in the abdomen. Participants randomized to FE 999049 had their individual dose determined on the basis of their anti-Müllerian hormone (AMH) level at screening and their body weight at randomization. The daily FE 999049 dose was fixed throughout the stimulation period. The minimum allowed daily FE 999049 dose was 6 μg and maximum allowed daily dose was 12 μg. Dosing continued until the criterion for triggering of final follicular maturation was met. Participants could be treated for a maximum of 20 days.
Follitropin beta	Follitropin beta	FOLLISTIM was administered as single daily subcutaneous injections in the abdomen. The starting dose of FOLLISTIM was 150 IU and fixed for the first five stimulation days, after which it could be adjusted by 75 IU based on the individual response. The maximum allowed daily dose was 375 IU. Dosing continued until the criterion for triggering of final follicular maturation was met. Participants could be treated for a maximum of 20 days.
