Efficacy and Safety of FE 999049 in Controlled Ovarian Stimulation in Japanese Women

A Randomised, Controlled, Assessor-blind, Parallel Groups, Multicentre Trial Assessing the Efficacy and Safety of FE 999049 in Controlled Ovarian Stimulation in Japanese Women Undergoing an Assisted Reproductive Technology Programme

To demonstrate non-inferiority of FE 999049 compared to FOLLISTIM with respect to number of oocytes retrieved in Japanese IVF/ICSI patients undergoing controlled ovarian stimulation.

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.
