BEKEMV 300 mg concentrate for solution for infusion – patient leaflet, side effects, dosage

1. What BEKEMV is and what it is used for

What is BEKEMV

BEKEMV contains the active substance eculizumab and it belongs to a class of medicines called monoclonal antibodies. Eculizumab binds to and inhibits a specific protein in the body that causes inflammation and so prevents your body’s systems from attacking and destroying vulnerable blood cells or kidneys.

What is BEKEMV used for

Paroxysmal Nocturnal Haemoglobinuria

BEKEMV is used to treat adults and children with a certain type of disease affecting the blood system called Paroxysmal Nocturnal Haemoglobinuria (PNH). In patients with PNH, their red blood cells can be destroyed which can lead to low blood counts (anaemia), tiredness, difficulty in functioning, pain, dark urine, shortness of breath, and blood clots. Eculizumab can block the body’s inflammatory response, and its ability to attack and destroy its own vulnerable PNH blood cells.

Atypical Haemolytic Uraemic Syndrome

BEKEMV is also used to treat adults and children with a certain type of disease affecting the blood system and kidney called atypical Haemolytic Uraemic Syndrome (aHUS). In patients with aHUS, their kidney and blood cells, including platelets, can be inflamed which can lead to low blood counts (thrombocytopenia and anaemia), reduced or lost kidney function, blood clots, tiredness and difficulty in functioning. Eculizumab can block the body’s inflammatory response, and its ability to attack and destroy its own vulnerable blood and kidney cells.

2. What you need to know before you use BEKEMV

Do not use BEKEMV

• If you are allergic to eculizumab or any of the other ingredients of this medicine (listed in section 6).
• In babies and young children below 2 years of age hereditary fructose intolerance (HFI) may not yet be diagnosed and may be fatal, thus, they must not receive this medicine (see “BEKEMV contains sorbitol”).
• If you have not been vaccinated against meningococcal infection unless you take antibiotics to reduce the risk of infection until 2 weeks after you have been vaccinated.
• If you have a meningococcal infection.

Warnings and precautions

Meningococcal and other Neisseria infections alert

BEKEMV treatment may reduce your natural resistance to infections, especially against certain organisms that cause meningococcal infection (severe infection of the linings of the brain and sepsis) and other Neisseria infections including disseminated gonorrhoea.

Consult your doctor before you take BEKEMV to be sure that you receive vaccination against Neisseria meningitidis, an organism that causes meningococcal infection, at least 2 weeks before beginning therapy, or that you take antibiotics to reduce the risk of infection until 2 weeks after you have been vaccinated.

Ensure that your current meningococcal vaccination is up to date. You should also be aware that vaccination may not prevent this type of infection. In accordance with national recommendations, your doctor might consider that you need supplementary measures to prevent infection.

If you are at risk of gonorrhoea, ask your doctor or pharmacist for advice before using this medicine.

Meningococcal infection symptoms

Because of the importance of rapidly identifying and treating certain types of infection in patients who receive BEKEMV, you will be provided a card to carry with you, listing specific trigger symptoms. This card is named: “Patient Card”.

If you experience any of the following symptoms, you should immediately inform your doctor:

• headache with nausea or vomiting
• headache with a stiff neck or back
• fever
• rash
• confusion
• severe muscle aches combined with flu-like symptoms
• sensitivity to light

Treatment for meningococcal infection while travelling

If you are travelling in a remote region where you are unable to contact your doctor or in which you find yourself temporarily unable to receive medical treatment, your doctor can make arrangements to issue, as a preventive measure, a prescription for an antibiotic to counter Neisseria meningitidis that you keep with you. If you experience any of the symptoms amongst those cited above, you should take the antibiotics as prescribed. You should bear in mind that you should see a doctor as soon as possible, even if you feel better after having taken the antibiotics.

Infections

Before starting BEKEMV, inform your doctor if you have any infections.

Allergic reactions

BEKEMV contains a protein and proteins can cause allergic reactions in some people.

Children and adolescents

Patients less than 18 years of age must be vaccinated against Haemophilus influenzae and pneumococcal infections.

Older people

There are no special precautions needed for the treatment of patients aged from 65 years and over.

Other medicines and BEKEMV

Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines.

Pregnancy, breast-feeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Women of childbearing potential

The use of effective contraception during treatment and up to 5 months after treatment should be considered in women who are able to get pregnant.

Driving and using machines

BEKEMV has no or negligible influence on the ability to drive and use machines.

BEKEMV contains sorbitol

This medicine contains 50 mg sorbitol in each mL.

Sorbitol is a source of fructose. If you (or your child) have hereditary fructose intolerance (HFI), a rare genetic disorder, you (or your child) must not receive this medicine. Patients with HFI cannot break down fructose, which may cause serious side effects.

You must tell your doctor before receiving this medicine if you (or your child) have HFI or if your child can no longer take sweet foods or drinks because they feel sick, vomit or get unpleasant effects such as bloating, stomach cramps or diarrhoea.

BEKEMV contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per dose, that is to say essentially “sodium free”.

BEKEMV contains polysorbate 80

This medicine contains 3.0 mg of polysorbate 80 in each vial (30 mL vial), which is equivalent to 0.3 mg/kg or less at the maximum dose for adult patients and paediatric patients with body weight more than 10 kg, and is equivalent to 0.6 mg/kg or less at the maximum dose for paediatric patients with body weight 5 to < 10 kg. Polysorbates may cause allergic reactions. Tell your doctor if you/your child has any known allergies.

3. How to use BEKEMV

At least 2 weeks before you start treatment with BEKEMV, your doctor will administer a vaccine against meningococcal infection if it was not previously administered or if your vaccination is outdated. If your child is below the age of vaccination or if you are not vaccinated at least 2 weeks before you start treatment with BEKEMV, your doctor will prescribe antibiotics to reduce the risk of infection until 2 weeks after you have been vaccinated.

Your doctor will administer a vaccine to your child aged less than 18 years against Haemophilus influenzae and pneumococcal infections according to the national vaccination recommendations for each age group.

Instructions for proper use

The treatment will be given by your doctor or other health care provider by infusing a dilution of the BEKEMV vial from a drip bag through a tube directly into one of your veins. It is recommended that the beginning of your treatments, called the initial phase, will extend over 4 weeks, followed by a maintenance phase.

If you use this medicine to treat PNH

For adults:

• Initial phase:

Every week for the first four weeks, your doctor will administer an intravenous infusion of diluted BEKEMV. Each infusion will consist of a dose of 600 mg (2 vials of 30 mL) and will take 25 - 45 minutes (35 minutes ± 10 minutes).

• Maintenance phase:
• In the fifth week, your doctor will administer an intravenous infusion of diluted BEKEMV at a dose of 900 mg (3 vials of 30 mL) over a 25 – 45 minute (35 minutes ± 10 minutes) period.
• After the fifth week, your doctor will administer 900 mg of diluted BEKEMV every two weeks as a long-term treatment.

If you use this medicine to treat aHUS

For adults:

• Initial phase:

Every week for the first four weeks, your doctor will administer an intravenous infusion of diluted BEKEMV. Each infusion will consist of a dose of 900 mg (3 vials of 30 mL) and will take 25 – 45 minutes (35 minutes ± 10 minutes).
