About

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.

Full 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.

150 µg Corifollitropin Alfa

Experimental group

Description:

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.
