1. what elonva is and what it is used for

Elonva contains the active ingredient corifollitropin alfa and belongs to the group of medicines called gonadotropic hormones. Gonadotropic hormones play an important role in human fertility and reproduction. One of these gonadotropic hormones is Follicle Stimulating Hormone (FSH), which is needed in women for the growth and development of follicles (small round sacs in your ovaries that contain the eggs).

Elonva is used to help achieve pregnancy in women having infertility treatment, such as in vitro fertilisation (IVF). IVF involves collecting the eggs from the ovary, fertilising them in the laboratory, and transferring the embryos into the uterus a few days later. Elonva causes the growth and development of several follicles at the same time by a controlled stimulation of the ovaries.

2. what you need to know before you use elonva

Do not use Elonva if you:

• - are allergic (hypersensitive) to corifollitropin alfa or any of the other ingredients of this medicine (listed in section 6)

• - have cancer of the ovary, breast, uterus, or brain (pituitary gland or hypothalamus)

• - have recently had unexpected vaginal bleeding, other than menstrual, without a diagnosed cause - have ovaries that do not work because of a condition called primary ovarian failure

• - have ovarian cysts or enlarged ovaries

• - have malformations of the sexual organs which make a normal pregnancy impossible

• - have fibroid tumours in the uterus which make a normal pregnancy impossible

• - have risk factor of OHSS (OHSS is a serious medical problem that can happen when the ovaries are overly stimulated. See below for further explanation.): o have polycystic ovarian syndrome (PCOS)

o have had ovarian hyperstimulation syndrome (OHSS)

o have previously had a treatment cycle of controlled stimulation of the ovaries that

resulted in the growth of more than 30 follicles with a size of 11 mm or larger

o have a basal antral follicle count (the number of small follicles present in your ovaries at the beginning of a menstrual cycle) higher than 20

Warnings and precautions

Talk to your doctor before using Elonva.

Ovarian hyperstimulation syndrome (OHSS)

Treatment with gonadotropic hormones like Elonva may cause ovarian hyperstimulation syndrome (OHSS). This is a serious medical condition where the ovaries are overly stimulated and the growing follicles become larger than normal. In rare cases, severe OHSS may be life-threatening. Therefore, close supervision by your doctor is very important. To check the effects of treatment, your doctor will do ultrasound scans of your ovaries. Your doctor may also check blood hormone levels. (See also section 4.)

OHSS causes fluid to build up suddenly in your stomach and chest areas and can cause blood clots to form. Call your doctor right away if you have:

• - severe abdominal swelling and pain in the stomach area (abdomen)

• - feeling sick (nausea)

• - vomiting

• - sudden weight gain due to fluid build up

• - diarrhoea

• - decreased urine output

• - trouble breathing

You may use Elonva only once during the same treatment cycle, otherwise, the chance of having OHSS may increase.

Before starting to use this medicine, tell your doctor if you have ever had ovarian hyperstimulation syndrome (OHSS).

Ovarian torsion

Ovarian torsion is the twisting of an ovary. Twisting of the ovary could cause the blood flow to the ovary to be cut off.

Before starting to use this medicine, tell your doctor if you:

• - have ever had ovarian hyperstimulation syndrome (OHSS).

• - are pregnant or think that you may be pregnant.

• - have ever had stomach (abdominal) surgery.

• - have ever had a twisting of an ovary.

• - have past or current cysts in your ovary or ovaries.

Blood clot (Thrombosis)

Treatment with gonadotropic hormones like Elonva may (just as pregnancy) increase the risk of having a blood clot (thrombosis). Thrombosis is the formation of a blood clot in a blood vessel.

Blood clots can cause serious medical conditions, such as:

• - blockage in your lungs (pulmonary embolus)

• - stroke

• - heart attack

• - blood vessel problems (thrombophlebitis)

• - a lack of blood flow (deep venous thrombosis) that may result in a loss of your arm or leg.

Please discuss this with your doctor, before starting treatment, especially if:

• - you know you already have an increased chance of having a thrombosis

• - you, or anyone in your immediate family, have ever had a thrombosis

• - you are severely overweight.

Multiple births or birth defects

There is an increased chance of having twins or even more than two babies, even when only one embryo is transferred into the uterus. Multiple pregnancies carry an increased health risk for both the mother and her babies. Multiple pregnancies and specific characteristics of couples with fertility problems (e.g., a woman’s age, certain sperm problems, genetic background of both parents) may also be associated with an increased chance of birth defects.

Pregnancy complications

If treatment with Elonva results in pregnancy, there is a higher chance of pregnancy outside the uterus (an ectopic pregnancy). Therefore, your doctor should perform an early ultrasound examination to exclude the possibility of pregnancy outside the uterus.

Ovarian and other reproductive system tumours

There have been reports of ovarian and other reproductive system tumours in women who have had infertility treatment. It is not known if treatment with fertility medicines increases the risk of these tumours in infertile women.

Other medical conditions

In addition, before starting to use this medicine, tell your doctor if you:

• - have kidney disease.

• - have uncontrolled pituitary gland or hypothalamic problems.

• - have an underactive thyroid gland (hypothyroidism).

• - have adrenal glands that are not working properly (adrenocortical insufficiency).

• - have high prolactin levels in the blood (hyperprolacti­nemia).

• - have any other medical conditions (for example, diabetes, heart disease, or any other long-term disease).

• - have been told by a doctor that pregnancy would be dangerous for you.

Other medicines and Elonva

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

If you do a pregnancy test during your infertility treatment with Elonva, the test might wrongly suggest that you are pregnant. Your doctor will advise you at what time you can start performing pregnancy tests. In case of a positive pregnancy test, contact your doctor.

Pregnancy and breast-feeding

You should not use Elonva if you are already pregnant, or think that you might be pregnant, or if you are breast-feeding.

Ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Elonva may cause dizziness. If you feel dizzy, you should not drive or use machines.

Elonva contains sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per injection, that is to say essentially ‘sodium-free’.

3. how to use elonva

Always use Elonva exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Elonva is used in women having infertility treatment like in vitro fertilisation (IVF). During this treatment, Elonva is used in combination with a medicine (so called GnRH-antagonist) to prevent your ovary from releasing an egg too early. Treatment with the GnRH-antagonist usually starts 5 to 6 days after the injection of Elonva.

The use of Elonva in combination with a GnRH agonist (another medicine to prevent your ovary from releasing an egg too early) is not recommended.

Dose

In the treatment of women of reproductive age, the dose of Elonva is based on weight and age.

- A single 100-microgram dose is recommended in women who weigh less than or equal to

60 kilograms and who are 36 years of age or younger.

- A single 150-microgram dose is recommended in women:

• – who weigh more than 60 kilograms, regardless of age.

• – who weigh 50 kilograms or more and who are older than 36 years of age.

Women older than 36 years of age who weighed less than 50 kilograms were not studied.

During the first seven days after the injection with Elonva, you should not use (recombinant) Follicle Stimulating Hormone ((rec)FSH). Seven days after the injection of Elonva, your doctor may decide to continue your stimulation cycle with another gonadotropic hormone, like (rec)FSH. This may be continued for a few days until enough follicles of adequate size are present. This can be checked by ultrasound examination. Treatment with (rec)FSH is then stopped and the eggs are matured by giving hCG (human Chorionic Gonadotropin). The eggs are collected from the ovary 34–36 hours later.

How Elonva is given

Treatment with Elonva should be supervised by a physician experienced in the treatment of fertility problems. Elonva must be injected under the skin (subcutaneously) into a skin fold (that you pinch between your thumb and index finger), preferably just below the navel. The injection may be given by a healthcare professional (for example a nurse), your partner or yourself, if carefully instructed by your doctor. Always use Elonva exactly as your doctor has told you. You should check with your doctor or pharmacist if you are unsure. A step-by-step “instructions for use” is given at the end of this leaflet.

Do not inject Elonva into a muscle.

Elonva is supplied in pre-filled syringes that have an automatic safety system to help prevent needle stick injuries after use.

If you use more Elonva or (rec)FSH than you should

If you think you have used more Elonva or (rec)FSH than you should, contact your doctor immediately.

If you forget to use Elonva

If you forgot to inject Elonva on the day you should have, contact your doctor immediately. Do not inject Elonva without talking with your doctor.

If you have any further questions on the use of this medicine, ask your doctor.

4. possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Serious side effects

A possible complication of treatment with gonadotropic hormones like Elonva is unwanted overstimulation of the ovaries. The chance of having this complication can be reduced by carefully monitoring the number of maturing follicles. Your doctor will do ultrasound scans of your ovaries to carefully monitor the number of maturing follicles. Your doctor may also check blood hormone levels. The first symptoms of ovarian overstimulation may be noticed as pain in the stomach (abdomen), feeling sick or diarrhoea. Ovarian overstimulation may develop into a medical condition called ovarian hyperstimulation syndrome (OHSS), which can be a serious medical problem. In more severe cases this may lead to enlargement of the ovaries, collection of fluid in the abdomen and/or chest (which may cause sudden weight gain due to fluid buildup) or clots in the blood vessels.

Contact your doctor without delay if you have pain in the stomach (abdomen) or any of the other symptoms of ovarian hyperstimulation, even if they occur some days after the injection has been given.

The chance of having a side effect is described by the following categories:

Common (may affect up to 1 in 10 women)

• – Ovarian hyperstimulation syndrome (OHSS)

• – Pelvic pain

• – Feeling sick (nausea)

• – Headache

• – Pelvic discomfort

• – Breast tenderness

• – Tiredness (fatigue)

Uncommon ( may affect up to 1 in 100 women)

• – Twisting of an ovary (ovarian torsion)

• – Liver enzyme increases

• – Miscarriage

• – Pain after oocyte retrieval

• – Procedural pain

• – Releasing an egg too early (premature ovulation)

• – Abdominal distension

• – Vomiting

• – Diarrhoea

• – Constipation

• – Back pain

• – Breast pain

• – Bruising or pain at the injection site

• – Irritability

• – Mood swings

• – Dizziness

• – Hot flush

Not known (cannot be estimated from available data)

• – Allergic reactions (hypersensitivity reactions, both local and generalised, including rash).

Pregnancy outside the uterus (an ectopic pregnancy) and multiple pregnancies have also been reported. These side effects are not considered to be related to the use of Elonva, but to Assisted Reproductive Technology (ART) or subsequent pregnancy.

In rare instances, blood clots (thrombosis) that formed inside a blood vessel, broke off, and travelled inside the bloodstream to block another blood vessel (thromboembolism) have been associated with Elonva therapy as with other gonadotropins.
