Study summary

A prospective, randomized, controlled study to explore the efficacy and safety of using either corifollitropin alfa 150 mcg or daily recombinant follicle stimulation hormone (FSH) 300 international unit (IU) for the stimulation treatment of subjects undergoing controlled ovarian stimulation prior to IVF.

The study is designed as a non-inferiority trial. The sample size for this trial of 400 subjects, in both groups, being treated for one IVF cycle is based upon the primary endpoint of the number of oocytes retrieved.

Read the detailed description

Stimulation regimen and assisted reproductive technology procedures

Corifollitropin Alfa Group: On day 2 or day 3 of the menstrual cycle, a single subcutaneous injection of corifollitropin alfa 150 mg/ 0.5 mL is administered (stimulation day 1).

FSH Group: Daily subcutaneous injections with recombinant FSH (Follitropin Beta) 300 international units (IU) is started on On day 2 or day 3 of the menstrual cycle (stimulation day 1) and continue up to and including stimulation day 7.

From stimulation day 8 onwards, subjects from both treatment groups will continue with a daily subcutaneous dose of FSH up to the day before human chorionic gonadotropin (hCG) administration or gonadotropin releasing hormone agonist administration day. The maximum FSH dose to continue treatment after the first 7 days is 300 IU, but the dose could be reduced when desired.

To prevent premature luteinizing hormone (LH) surges the gonadotropin releasing hormone (GnRH) antagonist (ganirelix acetate subcutaneous injection, 0.25 mg/ 0.5 mL) is administered, starting on stimulation day 5.

As soon as at least three follicles of 17 mm are observed by ultrasound, hCG or a GnRH agonist will be used for final oocyte maturation at the same day. hCG is used if 3-18 follicles and 0.2 mg triptorelin is administered if ≥ 19 follicles >11 mm are observed. About 34-36 hours thereafter, oocyte retrieval followed by IVF or intra-cytoplasmic sperm injection (ICSI) is performed. Three days after oocyte pick-up, 2 to 3 fresh embryos will be transferred. If patients have high progesterone level on day of trigger (progesterone level > 1,5 ng/ml), risk of OHSS and unfavorable endometrium, fresh transfers will be cancelled and freeze all will be recommended.

Patients using hCG for final oocyte maturation will receive luteal phase support with progestogen gel (90 mg once daily) intra-vaginally and estradiol (4 mg/day orally, twice daily) initiated on the day of oocyte retrieval or the day thereafter. Patients, using GnRH agonist for triggering, will have fresh transfer with intense luteal phase support of estradiol and progesterone (receive intense luteal phase support with estradiol and progesterone as the same dose mentioned above and progesterone 50 mg intramuscular injection per day).

Assessments

Patients will return to the clinic for pregnancy test 2 weeks after embryo transfers.

Local tolerance parameters (pain, itching, swelling and redness) are assessed by the clinical staff 30 min after injection for both corifollitropin alfa and FSH injection sites.

Clinical Outcome The primary objective is to show that the corifollitropin alfa regimen, in terms of the number of oocytes retrieved, is equivalent to the reference treatment (predefined equivalence range: -3 to +5 oocytes).

Other clinical parameters will also be evaluated: dose of FSH required, duration of stimulation, number and size of follicles (≥11mm and ≥14 mm), serum hormone levels, fertilization rate, number and quality of embryos obtained, implantation rate, miscarriage rate, and pregnancy rates.

At least 14 days after embryo transfer, a blood pregnancy test is performed. If the pregnancy test is positive, vaginal and/or abdominal ultrasonographic investigation is performed between 35 and 42 days ( 5 to 6 weeks) after embryo transfer to confirm a clinical pregnancy and at least 70 days (≥ 10 weeks) after embryo transfer to confirm an ongoing pregnancy.

Patients will be followed to one year after randomization.

All efficacy analyses will be based on the intent-to-treat (ITT) population, which included all randomized patients who will receive corifollitropin alfa or at least one dose of FSH

Safety endpoints

Occurrence of adverse events, including moderate and severe ovarian hyperstimulation syndrome (OHSS), outcome of local tolerance at injection site assessments will be evaluated as safety endpoints.

The percentage of patients with moderate or severe OHSS and local tolerance is compared between the treatment groups using Fisher's exact test.

Safety analyses will be performed on the all-subjects-treated group, which comprised all the patients who will receive either corifollitropin alfa or FSH.

Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Ran from Jun 2015 to primary completion in Aug 2016, 14 months.

Of 73 non-industry phase 4 interventional studies under Infertility, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 82. This study's 14 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 22, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
