Phase 3
Completed
Conditions
Infertility, Female
Interventions
Combination Product: Early follicular phase stimulation with recombinant-human FSH
Combination Product: Late follicular phase stimulation with recombinant-human FSH
Registration Number
NCT03767218
Lead Sponsor

Brief Summary

A randomised controlled open-label clinical trial to compare the outcome parameters after ovarian stimulation using recombinant-human FSH (follicle stimulating hormone), starting on day 2 of the cycle versus start in the late follicular phase of the cycle.

Detailed Description

Objective: To determine whether late follicular stimulation using recombinant-human FSH has comparable outcomes to treatment using recombinant-human FSH in early follicular phase in a flexible GnRH (Gonadotropin-releasing hormone) antagonist protocol, in oocyte donor patients.

Design: Open label, phase 3 randomized trial using a two-arm design with 1:1 allocation ratio

Patients: Oocyte donors (aged 18-36 years)

Intervention(s): Reference group: Start of ovarian stimulation with recombinant-human FSH (Bemfola 225 IU daily) from day 2 of follicular phase onwards. Initiation of GnRH antagonist (ganirelix, 0.25mg/day) on stimulation day 6 till day of trigger.

Investigational group: Start of ovarian stimulation with recombinant-human FSH (Bemfola 225 IU daily) from the late follicular phase of the menstrual cycle (evaluation trough ultrasound and hormonal assessment) onwards. Start of GnRH antagonist (ganirelix 0.25mg/day) when serum LH (Luteinizing Hormone) \> 10 IU/L, till day of trigger.

Oocyte maturation trigger with GnRH agonist (0.2mg Gonapeptyl) in both groups.
