A Phase IIIB, Multicentre, Multinational, Randomized, Open-label Trial to Compare the Efficacy and Safety of Ovarian Stimulation With GONAL-f® Day 1 to Day 5 Followed by Pergoveris® Starting Day 6 to Pergoveris® Starting Day 1 in Women Between 36 and 40 Years of Age Undergoing Assisted Reproductive Technique (ART)

Detailed Summary

This is a multicenter, multi-national, randomized, open-label comparative trial. After screening, the subjects will start down-regulation treatment on Day 21-22 of the cycle. Down-regulation treatment will start within 2 months following the screening visit. The routine long luteal phase protocol for gonadotropin-releasing hormone (GnRH) agonist treatment will be followed. Once down-regulation has been confirmed, a pregnancy test will be performed just before randomization and start of recombinant human follicle-stimulating hormone (r-hFSH) treatment to rule out any pre-existing pregnancy. If the result is negative, the subject will be randomly assigned to one of the two treatment arms of the trial: * GONAL-f®: (Liquid Pen; 300 international unit \[IU\] of per day) stimulation Day 1-5 followed by Pergoveris® (vial/powder, 300 IU per day) from stimulation Day 6 and until required recombinant human chorionic hormone (r-hCG) criterion is met. The dose can be adjusted from stimulation Day 6 (increased or decreased) based upon the subject's ovarian response and according to the center's standard practice. * Pergoveris®: (vial/powder, 300 IU per day) from stimulation Day 1 and until required r-hCG criterion is met. The dose can be adjusted from stimulation Day 6 (increased or decreased) based upon the subject's ovarian response and according to the center's standard practice. Randomization across the two treatment arms will be kept balanced in a 1:1 ratio. Follicular development will be monitored according to the center's standard practice by ultrasound (US) and/or estradiol (E2) levels, until the protocol r-hCG requirement is met (i.e., at least one follicle greater than or equal to \[\>=\] 18 millimeter \[mm\] and two follicles \>=16 mm). After this, a single injection of r-hCG will be administered in order to induce final oocyte maturation. At a time of 34-38 hours after r-hCG administration, oocytes will be recovered vaginally under US monitoring. Oocytes will then be fertilized in vitro and embryos replaced 2-5 days after oocyte recovery. Ovum pick up (OPU), in vitro fertilization (IVF), embryo transfer (ET) and luteal support will be performed as per center's standard practice. A post-treatment safety visit will be performed for all subjects who received r-hCG (pregnant and non- pregnant) on Day 15-20 post-hCG. For subjects who have withdrawn from treatment (i.e. after starting Pergoveris® or Gonal-f® but before hCG is given) this visit will take place 20-30 days after their first Pergoveris® or Gonal-f® treatment injection (excluding pregnancy testing).
