Phase 3

Completed

Conditions: Assisted Reproductive Techniques
Reproductive Technology, Assisted

Interventions: Drug: Pergoveris®
Drug: Gonal-f®
Drug: Recombinant human chorionic gonadotropin (r-hCG)

Registration Number: NCT01297465

Lead Sponsor: Merck KGaA, Darmstadt, Germany

Brief 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).

Any medical condition, which in the judgment of the investigator may interfere with the absorption, distribution, metabolism or excretion of the drug. In case of doubt, the subject in question should be discussed with Merck Serono's medical responsible
Had previous severe ovarian Hyperstimulation Syndrome (OHSS)
Polycystic ovary syndrome (PCOS; Rotterdam criteria) to reduce the risk of the occurrence of OHSS
Any contraindication to being pregnant and/or carrying a pregnancy to term
History of 3 or more miscarriages (early or late miscarriages) due to any cause
A clinically significant systemic disease
Known infection with Human Immunodeficiency Virus (HIV), Hepatitis B or C virus in the trial subject or her male partner
Known allergy or hypersensitivity to human gonadotrophin preparations
Entered previously into this trial or simultaneous participation in another clinical trial.
Pregnancy and lactation period
Participation in another clinical trial within the past 30 days
Other protocol specified inclusion criteria could also apply.

Primary Outcome Measures

Name	Time	Method
Total Number of Oocytes Retrieved	OPU day (34-38 hours post r-hCG day [end of stimulation cycle {approximately 11 days}])	The total number of oocytes retrieved per reporting group on the day of ovum pick-up (OPU) (34-38 hours post r-hCG day) was calculated. Oocyte retrieval is a technique used in in-vitro fertilization (IVF) in order to remove oocytes from the ovary of the female participant, enabling fertilization outside the body.

Secondary Outcome Measures

Name	Time	Method
Total Dose and Mean Daily Dose of Follicle Stimulating Hormone (FSH)	Day 1 up to r-hCG day (end of stimulation cycle [approximately 11 days])
Implantation Rate	Days 35-42 post r-hCG day (end of stimulation cycle [approximately 11 days])	Implantation rate per reporting group was measured as the number of fetal sacs observed, divided by the number of embryos transferred multiplied by 100.
Clinical Pregnancy Rate	Days 35-42 post r-hCG day (end of stimulation cycle [approximately 11 days])	Clinical pregnancy was defined as pregnancy diagnosed by ultrasonographic visualization of one or more gestational sacs or definitive clinical signs of pregnancy. It includes ectopic pregnancy. Clinical pregnancy rate was reported as total clinical pregnancy rate, clinical pregnancy rate per cycle started and per embryo transfer \[ET\]).
Systolic and Diastolic Arterial Blood Pressure Assessments	Days 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])
Total Number of Stimulation Treatment Days	Day 1 up to r-hCG day (end of stimulation cycle [approximately 11 days])
Number of Fetal Sacs With Activity	Days 35-42 post r-hCG day [end of stimulation cycle {approximately 11 days}])	Number of fetal sacs with activity was evaluated by ultrasound scan
Number of Fetal Hearts With Activity	Days 35-42 post r-hCG day [end of stimulation cycle {approximately 11 days}])	Number of fetal hearts with activity was evaluated by ultrasound scan
Number of Participants With Cancelled Cycles Due to Excessive or Insufficient Ovarian Response to Treatment	S1 until Day 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])	An excessive ovarian response: greater than or equal to 25 oocytes which could put the participant at risk of OHSS; An insufficient ovarian response: defined as 3 or less follicles of greater than or equal to 12 millimeter developing following at least 7 days of treatment.
Biochemical Pregnancies Rate	Days 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])	Biochemical pregnancy was defined as the pregnancy diagnosed only by the detection of human chorionic gonadotropin (hCG) in serum or urine and that does not develop into a clinical pregnancy. Participants with beta- hCG concentration greater than 10 international units per liter (IU/L) were considered as biochemical pregnant.
Heart Rate Assessments	Days 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])
Number of Participants With Multiple Pregnancies	Days 35-42 post r-hCG day (end of stimulation cycle [approximately 11 days])	Multiple pregnancy was defined as the existence of more than one fetal sac with fetal heart activity.
Number of Participants With Treatment-emergent Adverse Events	Day 1 up to days 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])	An adverse event (AE) was defined as any untoward medical occurrence in the form of signs, symptoms, abnormal laboratory findings, or diseases that emerges or worsens relative to baseline during a clinical study with an Investigational Medicinal Product (IMP), regardless of causal relationship and even if no IMP has been administered.
Number of Participants With Early and Late Ovarian Hyper Stimulation Syndrome (OHSS)	Days 15-20 post r-hCG day (end of stimulation cycle [approximately 11 days])	Ovarian Hyper Stimulation Syndrome (OHSS) is a syndrome which can manifest with enlarged ovaries, advanced ascites with increased vascular permeability, pleural fluid accumulation, hemoconcentration, and increased blood clotting. Early OHSS was defined as the onset of OHSS occurring within 9 days after oocyte retrieval and late OHSS was defined as the onset of OHSS occurring on or after day 10 from oocyte retrieval.
