United Kingdom24 participantsStarted 2025-11-24

Plain-language summary

The purpose of this study is to assess the Pharmacokinetic (PK) of Recombinant human follicle-stimulating hormone (follitropin alfa) (r-hFSH) and Recombinant human luteinizing hormone (lutropin alfa) (r-hLH) following a single subcutaneous injection of Pergoveris in pituitary-suppressed healthy female participants of Japanese or Caucasian origin. Study details include: Study Duration: Approximately 9 weeks Treatment Duration: Approximately 4 weeks downregulation with Marvelon® and a single dose of Pergoveris. Visit Frequency: Once in the Screening period, twice in the Downregulation period, and 8 continuous days in the study site during the Confinement period.

Inclusion Criteria: * Participant who are overtly healthy, as determined by medical evaluation, including medical history, physical examination, laboratory tests, and cardiac monitoring * Participant who have a negative urine pregnancy test before starting Marvelon and on the day before the Pergoveris dose (Day -1) * Participant who have a normal baseline FSH (\< 12 IU/L) and E2 levels less than or equal (\<=) 100 picogram per mililiter (pg/mL) and follicles \<= 11 millimeter (mm) in diameter at Screening * Participant who have a normal ThinPrep® cytologic test (TCT) during Screening * Other protocol defined inclusion criteria may apply Exclusion Criteria: * Participant with any condition that, in the Investigator's opinion, constitutes an inappropriate risk or a contraindication for participation in the study or that could interfere with the study objectives, conduct, or evaluation * Participants with any clinically significant abnormalities of the genital organs as determined by gynecological examination and transvaginal ultrasound scan (TVUS) and based on the Investigator's judgment (e.g. ovarian tumors, nonfunctional ovarian cysts, and endometrial hyperplasia) * Participant with imminent planned major surgery * Participant with a History of tumors of the pituitary gland or hypothalamus * Other protocol defined exclusion criteria may apply

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
