Pyzchiva 90 mg solution for injection in Pre-filled syringe – patient leaflet, side effects, dosage

1. What Pyzchiva is and what it is used for

What Pyzchiva is

Pyzchiva contains the active substance ‘ustekinumab’, a monoclonal antibody. Monoclonal antibodies are proteins that recognise and bind specifically to certain proteins in the body.

Pyzchiva belongs to a group of medicines called ‘immunosuppressants’. These medicines work by weakening part of the immune system.

What Pyzchiva is used for

Pyzchiva is used to treat the following inflammatory diseases:

• Plaque psoriasis - in adults and children aged 6 years and older
• Psoriatic arthritis - in adults
• Moderate to severe Crohn’s disease - in adults and children who weigh at least 40 kg
• Moderate to severe ulcerative colitis – in adults

Plaque psoriasis

Plaque psoriasis is a skin condition that causes inflammation affecting the skin and nails. Pyzchiva will reduce the inflammation and other signs of the disease. Pyzchiva is used in adults with moderate to severe plaque psoriasis, who cannot use ciclosporin, methotrexate or phototherapy, or where these treatments did not work. Pyzchiva is used in children and adolescents aged 6 years and older with moderate to severe plaque psoriasis who are unable to tolerate phototherapy or other systemic therapies or where these treatments did not work.

Psoriatic arthritis

Psoriatic arthritis is an inflammatory disease of the joints, usually accompanied by psoriasis. If you have active psoriatic arthritis you will first be given other medicines. If you do not respond well enough to these medicines, you may be given Pyzchiva to:

• Reduce the signs and symptoms of your disease.
• Improve your physical function.
• Slow down the damage to your joints.

Crohn’s disease

Crohn’s disease is an inflammatory disease of the bowel. If you have Crohn’s disease you will first be given other medicines. If you do not respond well enough or are intolerant to these medicines, you may be given Pyzchiva to reduce the signs and symptoms of your disease.

Ulcerative colitis

Ulcerative colitis is an inflammatory disease of the bowel. If you have ulcerative colitis you will first be given other medicines. If you do not respond well enough or are intolerant to these medicines, you may be given Pyzchiva to reduce the signs and symptoms of your disease.

2. What you need to know before you use Pyzchiva

Do not use Pyzchiva:

• If you are allergic to ustekinumab or any of the other ingredients of this medicine (listed in section 6).
• If you have an active infection which your doctor thinks is important. If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Pyzchiva.

Warnings and precautions

Talk to your doctor or pharmacist before using Pyzchiva. Your doctor will check how well you are before each treatment. Make sure you tell your doctor about any illness you have before each treatment. Also tell your doctor if you have recently been near anyone who might have tuberculosis. Your doctor will examine you and do a test for tuberculosis, before you have Pyzchiva. If your doctor thinks you are at risk of tuberculosis, you may be given medicines to treat it.

Look out for serious side effects

Pyzchiva can cause serious side effects, including allergic reactions and infections. You must look out for certain signs of illness while you are taking Pyzchiva. See ‘Serious side effects’ in section 4 for a full list of these side effects.

Before you use Pyzchiva tell your doctor:

• If you ever had an allergic reaction to ustekinumab. Ask your doctor if you are not sure.
• If you have ever had any type of cancer – this is because immunosuppressants like ustekinumab weaken part of the immune system. This may increase the risk of cancer.
• If you have been treated for psoriasis with other biologic medicines (a medicine produced from a biological source and usually given by injection) – the risk of cancer may be higher.
• If you have or have had a recent infection.
• If you have any new or changing lesions within psoriasis areas or on normal skin.
• If you are having any other treatment for psoriasis and/or psoriatic arthritis – such as another immunosuppressant or phototherapy (when your body is treated with a type of ultraviolet (UV) light). These treatments may also weaken part of the immune system. Using these therapies together with ustekinumab has not been studied. However it is possible it may increase the chance of diseases related to a weaker immune system.
• If you are having or have ever had injections to treat allergies – it is not known if ustekinumab may affect these.
• If you are 65 years of age or over – you may be more likely to get infections. If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Pyzchiva.

Some patients have experienced lupus-like reactions including skin lupus or lupus-like syndrome during treatment with ustekinumab. Talk to your doctor right away if you experience a red, raised, scaly rash sometimes with a darker border, in areas of the skin that are exposed to the sun or with joint pains.

Heart attack and strokes

Heart attack and strokes have been observed in a study in patients with psoriasis treated with ustekinumab. Your doctor will regularly check your risk factors for heart disease and stroke in order to ensure that they are appropriately treated. Seek medical attention right away if you develop chest pain, weakness or abnormal sensation on one side of your body, facial droop, or speech or visual abnormalities.

Children and adolescents

Ustekinumab is not recommended for use in children with psoriasis under 6 years of age, children with Crohn's disease who weigh less than 40 kg or for use in children under 18 years of age with psoriatic arthritis, or ulcerative colitis because it has not been studied in this age group.

Other medicines, vaccines and Pyzchiva

Tell your doctor or pharmacist:

• If you are taking, have recently taken or might take any other medicines.
• If you have recently had or are going to have a vaccination. Some types of vaccines (live vaccines) should not be given while using Pyzchiva.
• If you received Pyzchiva while pregnant, tell your baby’s doctor about your Pyzchiva treatment before the baby receives any vaccine, including live vaccines, such as the BCG vaccine (used to prevent tuberculosis). Live vaccines are not recommended for your baby in the first twelve months after birth if you received Pyzchiva during the pregnancy unless your baby’s doctor recommends otherwise.

Pregnancy and breast-feeding

• If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
• A higher risk of birth defects has not been seen in babies exposed to ustekinumab in the womb. However, there is limited experience with ustekinumab in pregnant women. It is therefore preferable to avoid the use of ustekinumab in pregnancy.
• If you are a woman of childbearing potential, you are advised to avoid becoming pregnant and must use adequate contraception while using ustekinumab and for at least 15 weeks after the last ustekinumab treatment.
• Ustekinumab can pass across the placenta to the unborn baby. If you received Pyzchiva during your pregnancy, your baby may have a higher risk for getting an infection.
• It is important that you tell your baby’s doctors and other health care professionals if you received Pyzchiva during your pregnancy before the baby receives any vaccine. Live vaccines such as the BCG vaccine (used to prevent tuberculosis) are not recommended for your baby in the first twelve months after birth if you received Pyzchiva during the pregnancy unless your baby’s doctor recommends otherwise.
• Ustekinumab may pass into breast milk in very small amounts. Talk to your doctor if you are breast-feeding or are planning to breast-feed. You and your doctor should decide if you should breast-feed or use ustekinumab -do not do both.

Driving and using machines

Ustekinumab has no or negligible influence on the ability to drive and use machines. Pyzchiva contains polysorbate 80 (E433)

This medicine contains 0.04 mg of polysorbate 80 (E433) in each pre-filled syringe (1 ml) which is equivalent to 0.04 mg/ml. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

3. How to use Pyzchiva

Pyzchiva is intended for use under the guidance and supervision of a doctor experienced in treating conditions for which Pyzchiva is intended.

Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. Talk to your doctor about when you will have your injections and follow-up appointments.

How much Pyzchiva is given

Your doctor will decide how much Pyzchiva you need to use and for how long. Adults aged 18 years or older Psoriasis or Psoriatic Arthritis

• The recommended starting dose is 45 mg Pyzchiva. Patients who weigh more than 100 kilograms (kg) may start on a dose of 90 mg instead of 45 mg.
• After the starting dose, you will have the next dose 4 weeks later, and then every 12 weeks. The following doses are usually the same as the starting dose. Crohn’s disease or Ulcerative Colitis
• During treatment, the first dose of approximately 6 mg/kg Pyzchiva will be given by your doctor through a drip in a vein in your arm (intravenous infusion). After the starting dose, you will receive the next dose of 90 mg Pyzchiva after 8 weeks, then every 12 weeks thereafter by an injection under the skin (‘subcutaneously’).
• In some patients, after the first injection under the skin, 90 mg Pyzchiva may be given every 8 weeks. Your doctor will decide when you should receive your next dose. Children and adolescents aged 6 years or older

Psoriasis

• Pyzchiva is not indicated for paediatric plaque psoriasis patients who weigh less than 60 kg as Pyzchiva is only available as 45 mg and 90 mg pre-filled syringe for subcutaneous injection. Thus, if alternate dose is required, other ustekinumab products offering such an option should be used.
• The doctor will work out the right dose for you, including the amount (volume) of Pyzchiva to be injected to give the right dose. The right dose for you will depend on your body weight at the time each dose is given.
• If you weigh 60 kg to 100 kg, the recommended dose is 45 mg Pyzchiva.
• If you weigh more than 100 kg, the recommended dose is 90 mg Pyzchiva.
• After the starting dose, you will have the next dose 4 weeks later, and then every 12 weeks. Children who weigh at least 40 kg

Crohn’s disease

• During treatment, the first dose of approximately 6 mg/kg Pyzchiva will be given by your doctor through a drip in a vein in your arm (intravenous infusion). After the starting dose, you will receive the next dose of 90 mg Pyzchiva after 8 weeks, then every 12 weeks thereafter by an injection under the skin (‘subcutaneously’).
• In some patients, after the first injection under the skin, 90 mg Pyzchiva may be given every 8 weeks. Your doctor will decide when you should receive your next dose. How Pyzchiva is given
• Pyzchiva is given as an injection under the skin (‘subcutaneously’). At the start of your treatment, medical or nursing staff may inject Pyzchiva.
• However, you and your doctor may decide that you may inject Pyzchiva yourself. In this case you will get training on how to inject Pyzchiva yourself.
• For instructions on how to inject Pyzchiva, see ‘Instructions for administration’ at the end of this leaflet.

Talk to your doctor if you have any questions about giving yourself an injection. If you use more Pyzchiva than you should

If you have used or been given too much Pyzchiva, talk to a doctor or pharmacist straight away. Always have the outer carton of the medicine with you, even if it is empty. If you forget to use Pyzchiva

If you forget a dose, contact your doctor or pharmacist. Do not take a double dose to make up for a forgotten dose.

If you stop using Pyzchiva

It is not dangerous to stop using ustekinumab. However, if you stop, your symptoms may come back. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

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

Some patients may have serious side effects that may need urgent treatment. Allergic reactions – these may need urgent treatment. Tell your doctor or get emergency medical help straight away if you notice any of the following signs.

• Serious allergic reactions (‘anaphylaxis’) are rare in people taking ustekinumab (may affect up to 1 in 1,000 people). Signs include:

  • difficulty breathing or swallowing
  • low blood pressure, which can cause dizziness or light-headedness
  • swelling of the face, lips, mouth or throat.
• Common signs of an allergic reaction include skin rash and hives (these may affect up to 1 in 100 people).

In rare cases, allergic lung reactions and lung inflammation have been reported in patients who receive ustekinumab. Tell your doctor right away if you develop symptoms such as cough, shortness of breath, and fever.

If you have a serious allergic reaction, your doctor may decide that you should not use Pyzchiva again.

Infections – these may need urgent treatment. Tell your doctor straight away if you notice any of the following signs.

• Infections of the nose or throat and common cold are common (may affect up to 1 in 10 people)
• Infections of the chest are uncommon (may affect up to 1 in 100 people)
• Inflammation of tissue under the skin (‘cellulitis’) is uncommon (may affect up to 1 in 100 people)
• Shingles (a type of painful rash with blisters) are uncommon (may affect up to 1 in 100 people)

Ustekinumab may make you less able to fight infections. Some infections could become serious and may include infections caused by viruses, fungi, bacteria (including tuberculosis), or parasites, including infections that mainly occur in people with a weakened immune system (opportunistic infections). Opportunistic infections of the brain (encephalitis, meningitis), lungs, and eye have been reported in patients receiving treatment with ustekinumab.

You must look out for signs of infection while you are using ustekinumab. These include:

• fever, flu-like symptoms, night sweats, weight loss
• feeling tired or short of breath; cough which will not go away
• warm, red and painful skin, or a painful skin rash with blisters
• burning when passing water
• diarrhoea
• visual disturbance or vision loss
• headache, neck stiffness, light sensitivity, nausea or confusion.

Tell your doctor straight away if you notice any of these signs of infection. These may be signs of infections such as chest infections, skin infections, shingles or opportunistic infections that could have serious complications. Tell your doctor if you have any kind of infection that will not go away or keeps coming back. Your doctor may decide that you should not use ustekinumab until the infection goes away. Also tell your doctor if you have any open cuts or sores as they might get infected.

Shedding of skin – increase in redness and shedding of skin over a larger area of the body may be symptoms of erythrodermic psoriasis or exfoliative dermatitis, which are serious skin conditions. You should tell your doctor straight away if you notice any of these signs. Other side effects

Common side effects (may affect up to 1 in 10 people):

• Diarrhoea
• Nausea
• Vomiting
• Feeling tired
• Feeling dizzy

Instructions for administration

At the start of treatment, your healthcare provider will assist you with your first injection. However, you and your doctor may decide that you may inject Pyzchiva yourself. If this happens, you will get training on how to inject Pyzchiva. Talk to your doctor if you have any questions about giving yourself an injection.

• Do not mix Pyzchiva with other liquids for injection

• Do not shake Pyzchiva pre-filled syringes. This is because strong shaking may damage the medicine. Do not use the medicine if it has been shaken strongly. Figure 1 shows what the pre-filled syringe looks like.

  Figure 1

  1. 1. Check the number of pre-filled syringes and prepare the materials:

Preparing for use of the pre-filled syringe

• Take the pre-filled syringe(s) out of the refrigerator. Let the pre-filled syringe stand outside the box for about half an hour. This will let the liquid come to a comfortable temperature for injection (room temperature). Do not warm the pre-filled syringe in any other way (for example, do not warm it in a microwave or in hot water.) Do not remove the syringe’s needle cover while allowing it to reach room temperature
• Hold the pre-filled syringe by the body of the syringe with the covered needle pointing upward
• Do not hold by the plunger head, plunger, needle guard wings, or needle cover
• Do not pull back on the plunger at any time
• Do not remove the needle cover from the pre-filled syringe until instructed to do so

Check the pre-filled syringe(s) to make sure

• the number of pre-filled syringes and strength is correct

  • If your dose is 90 mg you will get one 90 mg pre-filled syringe of Pyzchiva.
• it is the right medicine
• it has not passed its expiry date
• the pre-filled syringe is not damaged
• the solution in the pre-filled syringe is clear and colourless to light yellow
• the solution in the pre-filled syringe is not discoloured or cloudy and does not contain any foreign particles
• the solution in the pre-filled syringe is not frozen.

Get everything together that you need and lay out on a clean surface. This includes antiseptic wipes, a cotton ball or gauze, and a sharps container.

1. 2. Choose and prepare the injection site:

Choose an injection site (see Figure 2)

• Pyzchiva is given by injection under the skin (subcutaneously)
• Good places for the injection are the upper thigh or around the belly (abdomen) at least 5 cm away from the navel (belly button)
• If possible, do not use areas of skin that show signs of psoriasis

• If someone will assist in giving you the injection, then he or she may also choose the upper arms as an injection site.

  *Areas in gray are recommended injection sites.

  Figure 2

Prepare the injection site

• Wash your hands very well with soap and warm water
• Wipe the injection site on the skin with an antiseptic wipe
• Do not touch this area again before giving the injection.

• Do not fan or blow on the clean area

  1. 3. Remove the needle cover (see Figure 3):
• The needle cover should not be removed until you are ready to inject the dose
• Pick up the pre-filled syringe, hold the body of the syringe with one hand

• Pull the needle cover straight off and throw it away. Do not touch the plunger while you do this

  Figure 3

• You may notice an air bubble in the pre-filled syringe or a drop of liquid at the end of the needle. These are both normal and do not need to be removed
• Do not touch the needle or allow it to touch any surface
• Do not use the pre-filled syringe if it is dropped without the needle cover in place. If this happens, please contact your doctor or pharmacist

• Inject the dose promptly after removing the needle cover.

  1. 4. Inject the dose:
• Hold the pre-filled syringe with one hand between the middle and index fingers and place the thumb on top of the plunger head and use the other hand to gently pinch the cleaned skin between your thumb and index finger. Do not squeeze it tightly
• Do not pull back on the plunger at any time

• In a single and swift motion, insert the needle through the skin as far as it will go (see Figure 4)

  Figure 4

  • Inject all of the medication by pushing in the plunger until the plunger head is completely between the needle guard wings (see Figure 5)

    Figure 5

  • When the plunger is pushed as far as it will go, continue to keep the pressure on the plunger head, take out the needle and let go of the skin (see Figure 6)

    Figure 6

  • Slowly take your thumb off the plunger head to allow the empty syringe to move up until the entire needle is covered by the needle guard, as shown by Figure 7:

    Figure 7

    1. 5. After the injection:
  • Press an antiseptic wipe over the injection site for a few seconds after the injection.
  • There may be a small amount of blood or liquid at the injection site. This is normal.
  • You can press a cotton ball or gauze over the injection site and hold for 10 seconds.

  • Do not rub the skin at the injection site. You may cover the injection site with a small adhesive bandage, if necessary.

    1. 6. Disposal:
  • Used syringes should be placed in a puncture-resistant container, like a sharps container (see Figure 8). Never re-use a syringe, for your safety and health and for the safety of others. Dispose of your sharps container according to your local regulations

  • Antiseptic wipes and other supplies can be disposed of in your garbage.
