The purpose of the present study is to analyse if corifollitropin alfa, an agent for prolonged ovarian stimulation, administered from day 4 can be clinically used instead of day 2 onwards for a controlled ovarian hyperstimulation (COH) in an antagonist protocol.

Primary Outcome Measures:
  • Consumption of rFSH at the end of the follicular phase [ Time Frame: up to 9 months ] [ Designated as safety issue: No ]
    The purpose is to assess the additional need for recFSH in each treatment group

Secondary Outcome Measures:
  • Pregnancy rate [ Time Frame: Up to 9 months ] [ Designated as safety issue: No ]
    The purpose is to study the pregnancy rate in each treatment group

Estimated Enrollment: 50
Study Start Date: December 2011
Estimated Study Completion Date: February 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Day 2 group
Patients undergo a standard treatment with a classical start of corifollitropin alfa in a GnRH antagonist protocol.
Drug: corifollitropin alfa
long acting FSH
Active Comparator: Day 4 group
Patients undergo an ovarian stimulation, but start on day 4 with corifollitropin alfa
Drug: corifollitropin alfa
long acting FSH

Detailed Description:

Corifollitropin alfa is a new recombinant gonadotrophin with sustained follicle-stimulating activity. It offers novel and effective treatment option for potential normal responder patients undergoing ovarian stimulation with GnRH antagonist co-treatment for IVF or in vitro fertilisation resulting in a high ongoing pregnancy rate, equal to that achieved with daily rFSH. Normally, this medication is started on day 2 of the cycle. In the present randomised trial, we want to evaluate whether this agent can be clinically used when started on day 4 of the cycle.
