Scientific title

Efficacy, safety and tolerability of XM17 compared to Gonal-f® in women undergoing assisted reproductive technologies: a multinational, multicentre, randomised, controlled, assessor-blind, parallel group phase III study including follow-up periods


Study hypothesis

The primary objective is to show equivalent efficacy of XM17 (human recombinant follicle-stimulating hormone) compared to Gonal-f® in infertile women undergoing assisted reproductive technologies (ART).

After checking the suitability of the patient, the patients will be down-regulated with a gonadotropin releasing hormone agonist. After successful down-regulation the patients will be randomised to a treatment with 150 IU/d XM17 (human recombinant FSH) or 150 IU/d Gonal-f® (follitropin alpha). During the first 5 days the dose is fixed to 150 IU/d and thereafter the dose of follicle stimulating hormone (FSH) can be adapted. After successful ovarian stimulation human chorionic gonadotropin will be administered. The cumulus oocyte complexes will be retrieved. Embryo transfer will be performed. A pregnancy test will be done about 16 - 19 days after oocyte retrieval. Clinical pregnancy (foetal heart beat, gestational sacs) will be evaluated by ultrasound examination about 5 - 7 weeks after oocyte retrieval. Patients being pregnant will be followed up until they give birth (follow-up part A). Patients not being pregnant can be treated for a second or third cycle with XM17 as stimulating drug (follow-up part B).
