CONSORT Randomized Controlled Trial in Assisted Reproductive Technology

Phase 4
Completed
Conditions
Infertility
Interventions
Drug: GONAL f® prefilled pen
Registration Number
NCT00829244
Lead Sponsor
Merck KGaA, Darmstadt, Germany
Brief Summary

The overall objective of this trial is to compare the ovarian response in assisted reproductive technology (ART) subjects administered GONAL f® according to the 'Consistency in recombinant follicle stimulating hormone \[r-FSH\] starting doses for individualized treatment' (CONSORT) calculator versus given a standard GONAL f® dose of 150 International Unit (IU) per day.

Target Recruitment

Inclusion Criteria
  1. Female subjects justifying an in-vitro fertilization (IVF)/embryo transfer (ET) treatment
  2. Have a male partner with semen analysis within the past 6 months prior to randomization considered adequate to proceed with regular insemination or intracytoplasmic sperm injection (ICSI) according to the center's standard practice. If these criteria are not met, the subject can only be entered if donor sperm will be used
  3. Between her 18th and 35th birthday (35 not included) at the time of the randomization visit
  4. Body mass index (BMI) lower than 30 kilogram per square meter (kg/m^2) where the BMI is calculated according to the formula
  5. Have a regular spontaneous ovulatory menstrual cycle between 21 and 35 days in length
  6. Have an early follicular phase (Day 2-4) serum level of basal FSH lower than or equal to 12 International Unit per Liter (IU/L) measured in the center's local laboratory during the screening period (i.e. within 2 months prior to down-regulation start)
  7. Presence of both ovaries
  8. Normal uterine cavity, which in the investigator's opinion is compatible with pregnancy
  9. Have a negative cervical papanicolaou (PAP) test within the last 6 months prior to randomization
  10. Have at least 1 wash-out cycle (defined as greater than or equal to 30 days since the last dose of clomiphene citrate or gonadotrophin treatment) since the last ART cycle and/or clomiphene citrate or gonadotrophin treatment prior to starting gonadotropin releasing hormone (GnRH) agonist therapy
  11. Willing and able to comply with the protocol for the duration of the trial
  12. Have given written informed consent, prior to any trial-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to her future medical care
Exclusion Criteria
  1. Have greater than or equal to 2 previous ART cycles with a poor response to gonadotrophin stimulation (defined as lower than or equal to 5 mature follicles and/or lower than or equal to 3 oocytes collected) or have greater than or equal to 2 previous ART cycles with a hyper response (defined as greater than or equal to 25 oocytes retrieved)
  2. 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
  3. Have previous severe ovarian hyperstimulation syndrome (OHSS)
  4. Polycystic ovary syndrome (PCOS; Rotterdam criteria) to reduce the risk of the occurrence of OHSS
  5. Presence of endometriosis requiring treatment
  6. Uterine myoma requiring treatment
  7. Any contraindication to being pregnant and/or carrying a pregnancy to term
  8. Extra-uterine pregnancy within the last 3 months prior to screening
  9. History of 3 or more miscarriages (early or late miscarriages) due to any cause
  10. Tumors of the hypothalamus and pituitary gland
  11. Ovarian enlargement or cyst of unknown etiology
  12. Ovarian, uterine or mammary cancer
  13. A clinically significant systemic disease
  14. Known infection with Human Immunodeficiency Virus (HIV), Hepatitis B or C virus in the trial subject or her male partner,
  15. Abnormal gynecological bleeding of undetermined origin
  16. Known allergy or hypersensitivity to human gonadotrophin preparations,
  17. Any active substance abuse or history of drug medication or alcohol abuse in the past 5 years prior to the screening visit
  18. Entered previously into this trial or simultaneous participation in another clinical trial

CONSORT DosingGONAL f® prefilled penGONAL-f® dose based on subject baseline characteristics determined according to the CONSORT calculator
Standard DosingGONAL f® prefilled penGONAL-f® at a standard dose of 150 IU per day
Primary Outcome Measures
NameTimeMethod
Number of Oocytes Retrieved Per Participant34-38 hours post-recombinant human choriogonadotropin (hCG) (OPU)

Mean number of oocytes retrieved on the day of ovum pick up (OPU) was calculated. Oocyte retrieval is a technique used in in-vitro fertilization in order to remove oocytes from the ovary of the female, enabling fertilization outside the body.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Biochemical PregnanciesStart of treatment until Day 15-20 Post-hCG

Biochemical pregnancy was defined as a pregnancy diagnosed only by the detection of hCG in serum and that does not develop into a clinical pregnancy.

Total GONAL-f® DoseStart of treatment until end of stimulation cycle (approximately 28 days)
Mean GONAL-f® Daily DoseStart of treatment until end of stimulation cycle (approximately 28 days)
Total Number of GONAL-f® Stimulation Treatment DaysStart of treatment until end of stimulation cycle (approximately 28 days)
Number of Participants With Cancelled Cycles Due to Excessive or Inadequate Response to TreatmentStart of treatment until Day 15-20 post-hCG

Number of participants with cancelled cycles due to excessive or inadequate response was evaluated. An excessive response: greater than or equal to 25 oocytes which could put the participant at risk of OHSS; An inadequate response: defined as 3 or less follicles of greater than or equal to 12 millimeter (mm) developing following at least 7 days of GONAL-f® treatment.

Number of Participants With Fetal Sacs and Fetal HeartsDay 35-42 Post-hCG

Number of participants with fetal sacs and fetal hearts (with activity) as seen on an ultrasound scan to confirm clinical pregnancy.

Implantation RateDay 35-42 Post-hCG

Implantation rate was measured as the number of gestational sacs observed divided by the number of embryos transferred multiplied by 100.

Number of Participants With Multiple PregnanciesDay 35-42 Post-hCG

Multiple pregnancy was defined as 2 or more fetal hearts with activity.

Serum Progesterone (P4) LevelsEnd of stimulation cycle (approximately 28 days)
Pregnancy Outcome - Number of Participants With Pregnancy and Their Outcomeup to 9 month (following the end of treatment)

Pregnancy outcomes are live outcome (live infant) and non-live outcome (non-live infant) or unknown outcome (subject lost to follow-up).

Percentage of Participants With Clinical PregnancyDay 35-42 Post-hCG

Clinical pregnancy is defined by the number of sacs and hearts with activity per ultrasound scan performed on Day 35-42 post-hCG.

Number of Participants With OHSSStart of treatment until Day 15-20 Post-hCG

OHSS is a syndrome which can manifest with enlarged ovaries, advanced ascites with increased vascular permeability, pleural fluid accumulation, hemoconcentration, and increased blood clotting.
