Brief summary:
To investigate the efficacy and safety of a single injection of 150 μg Corifollitropin Alfa (Organon 36286) to induce multifollicular development for controlled ovarian stimulation using daily recombinant FSH (recFSH) as a reference. The primary hypothesis is that a single injection of Corifollitropin Alfa is non-inferior to daily treatment with recFSH in initiating multifollicular growth.

Detailed description:
This is a randomized, double-blind, active-controlled, non-inferiority clinical trial investigating the efficacy and safety of a new treatment regimen with Corifollitropin Alfa, a recombinant gonadotropin applied to initiate and sustain follicular stimulation in controlled ovarian stimulation for Assisted Reproductive Technology (ART). For this regimen, participants receive a single injection of Corifollitropin Alfa and one week later, treatment is continued with daily recFSH up to the day of triggering final oocyte maturation. In the reference group participants receive daily injections of recFSH up to the day of triggering final oocyte maturation. Non-inferiority in ongoing pregnancy rates (assessed at least 10 weeks after embryo transfer) will be the primary endpoint for this trial. The number of oocytes retrieved will be analyzed as co-primary endpoint.

Arms: arm 1: Participants received a single subcutaneous (SC) injection of 150 µg Corifollitropin Alfa (org 36286) on day 2 or 3 of the menstrual cycle (Stimulation Day 1); 7 daily SC injections from Stimulation Days 1 to 7 with placebo-recFSH; followed by daily SC injections with 200 IU recFSH up to the day of hCG. Daily SC injections of Ganirelix were administered from Stimulation Day 5 to the day of hCG; at which time a single dose of hCG was given when 3 follicles \>= 17 mm. On the day of oocyte pick up (OPU) daily doses of progesterone were started and continued for up to 6 weeks or menses. arm 2: Participants received a single SC injection of placebo Corifollitropin Alfa on day 2 or 3 of the menstrual cycle (Stimulation Day 1); 7 daily SC injections with 200 IU recFSH from Stimulation Days 1 to 7; followed by daily SC injections with 200 IU recFSH up to the day of hCG. Daily SC injections of Ganirelix were given from Stimulation Day 5 to the day of hCG; at which time a single dose of hCG was administered when 3 follicles \>= 17 mm. On the day of OPU daily doses of progesterone were started and continued for up to 6 weeks or menses.
Interventions: intervention 1: Corifollitropin alfa intervention 2: RecFSH / Follitropin beta (Days 1 to 7) intervention 3: Placebo Corifollitropin alfa intervention 4: Placebo RecFSH / follitropin beta intervention 5: RecFSH / Follitropin beta (Days 8 to hCG) intervention 6: Ganirelix intervention 7: hCG intervention 8: Progesterone
Intervention descriptions: intervention 1: On the morning of day 2 or 3 of the menstrual cycle (Stimulation Day 1), a single SC injection of 150 μg (0.5 mL) Corifollitropin Alfa was administered in the abdominal wall. intervention 2: Daily SC injections with 200 IU fixed dose recFSH were started on Stimulation Day 1 and continued up to and including Stimulation Day 7. intervention 3: Pre-filled syringe containing an identical solution when compared to Corifollitropin Alfa. On the morning of day 2 or 3 of the menstrual cycle (Stimulation Day 1), a single SC injection was administered in the abdominal wall. intervention 4: Identical ready-for-use solution, but without the active ingedient, supplied in cartridges for SC injection with the Follistim Pen. Daily SC injections were started on Stimulation Day 1 and continued up to and including Stimulation Day 7. intervention 5: From Stimulation Day 8 onwards a daily SC dose of 200 IU recFSH was administered up to and including the Day of hCG. intervention 6: On Stimulation Day 5 a daily SC injection of 0.25 mg was started, which continued up to and including the day of hCG intervention 7: When 3 follicles \>= 17 mm were observed by USS, a single dose of 10,000 IU/USP hCG was administered; or, for those at risk for Ovarian Hyperstimulation Syndrome (OHSS), a lower dose of 5,000 IU/USP intervention 8: On the day of OPU, luteal phase support was started by administering micronized progesterone of at least 600 mg/day vaginally, or at least 50 mg/day intramuscular (IM), which continued for at least 6 weeks, or up to menses.
