Patient leaflet - Kevzara 150 mg solution for injection in Pre-filled pen

1. What Kevzara is and what it is used for

What Kevzara is

Kevzara contains the active substance sarilumab. It is a type of protein - called a “monoclonal antibody”.

What Kevzara is used for

Kevzara is used to treat adults with moderately to severely active rheumatoid arthritis (RA) if previous therapy did not work well enough or was not tolerated. Kevzara can be used alone or together with a medicine called methotrexate (MTX).

It may help you by:

  • slowing down damage to joints
  • improving your ability to perform daily activities.

Kevzara is used to treat adults with polymyalgia rheumatica after corticosteroids have been used and did not work well or if you experience a relapse while decreasing the dose of corticosteroids (taper). Kevzara can be used alone or together with a medicine called corticosteroid.

How Kevzara works

  • Kevzara attaches to another protein called interleukin-6 (IL-6) receptor and blocks its action.
  • IL-6 plays a major role in the symptoms of RA such as pain, swollen joints, morning stiffness, and fatigue.

2. What you need to know before you use Kevzara

Do not use Kevzara:

  • if you are allergic to sarilumab or any of the other ingredients of this medicine (listed in section 6).
  • if you have an active severe infection.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse if:

  • you have any infection or, you get a lot of infections. Kevzara can lower your body's ability to fight infection and this means it can make you more likely to get infections or make your infection worse.
  • you have tuberculosis (TB), symptoms of TB (persistent cough, weight loss, listlessness, mild fever), or have been in close contact with someone with TB. Before you are given Kevzara, your doctor will check you for TB.
  • you have had viral hepatitis or other liver disease. Before you use Kevzara, your doctor will do a blood test to check your liver function.

    • you have had diverticulitis (a condition of the lower bowel) or ulcers in your stomach or intestines, or develop symptoms such as fever and stomach (abdominal) pain that does not go away.
    • you have ever had any type of cancer.
    • you have recently had any vaccination or are going to have a vaccination.

If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before using Kevzara.

You will have blood tests before you are given Kevzara. You will also have the tests during your treatment. This is to check if you have a low blood cell count, liver problems, or changes in your cholesterol levels.

Every time you get a new pack of Kevzara, it is important you note down the name of the medicine, the date of the administration and the batch number (which is on the packaging after “Lot”) and keep this information in a safe place.

Children and adolescents

The Kevzara pre-filled pen has not been studied in children 2 years of age and older with polyarticular juvenile idiopathic arthritis (pJIA) and is not

intended for use in children. Kevzara is not recommended in children under 2 years of age. Kevzara must not be given to children with pJIA weighing less than 10 kg.

Other medicines and Kevzara

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

This is because Kevzara can affect the way some other medicines work. Also some other medicines can affect the way Kevzara works.

In particular, do not use

Kevzara and tell your doctor or pharmacist if you are using:

  • a group of medicines called “Janus kinase (JAK) inhibitors” (used for diseases like

    rheumatoid arthritis and cancer)

  • other biological medicines used in the treatment of RA. If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist.

    Kevzara can affect the way some medicines work: this means the dose of other medicines may need changing. If you are using any of the following medicines, tell your doctor or pharmacist before using Kevzara:

    • statins, used to reduce cholesterol level
    • oral contraceptives
    • theophylline, used to treat asthma
    • warfarin, used to prevent blood clots

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist.

Pregnancy and breast-feeding

Talk to your doctor before using Kevzara if you are pregnant or breast feeding, think you may be pregnant or are planning to have a baby.

  • Do not take Kevzara if you are pregnant – unless your doctor specifically recommends it.
  • The effects of Kevzara on an unborn baby are not known
  • You and your doctor should decide if you should use Kevzara if you are breast-feeding.

Driving and using machines

The use of Kevzara is not expected to affect your ability to drive or use machines. However, if you are feeling tired or unwell after you use Kevzara, you should not drive or use machines.

Kevzara contains polysorbate 20

This medicine contains 2.28 mg of polysorbate 20 in each 1.14 mL of solution for injection which is equivalent to 2 mg/mL. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

3. How to use Kevzara

Treatment should be started by a doctor experienced in the diagnosis and treatment of RA or polymyalgia rheumatica. Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Adult Patients

The recommended dose is one 200 mg injection every two weeks.
