Patient leaflet - Otulfi 45 mg solution for injection in Pre-filled pen

1. What Otulfi is and what it is used for

What Otulfi is

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

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

What Otulfi is used for

Otulfi administered using pre-filled pen is used to treat the following inflammatory diseases:

  • Plaque psoriasis - in adults
  • Psoriatic arthritis - in adults
  • Moderate to severe Crohn’s disease - in adults
  • Moderate to severe ulcerative colitis - in adults

Plaque psoriasis

Plaque psoriasis is a skin condition that causes inflammation affecting the skin and nails. Otulfi will reduce the inflammation and other signs of the disease.

Otulfi administered using pre-filled pen is used in adults with moderate to severe plaque psoriasis, who cannot use ciclosporin, methotrexate or phototherapy, 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 Otulfi 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 Otulfi 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 Otulfi to reduce the signs and symptoms of your disease

2. What you need to know before you use Otulfi

Do not use Otulfi

  • 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 Otulfi.

Warnings and precautions

Talk to your doctor or pharmacist before using Otulfi. 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 Otulfi. If your doctor thinks you are at risk of tuberculosis, you may be given medicines to treat it.

Look out for serious side effects

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

Before you use Otulfi 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 Otulfi 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 have ever had an allergic reaction to Otulfi injection –See ‘Look out for serious side effects’ in section 4 for the signs of an allergic reaction. • 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 Otulfi 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 Otulfi 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 Otulfi.

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

The Otulfi pre-filled pen is not recommended for use in children and adolescents under 18 years of age with psoriasis or Crohn’s disease because it has not been studied in this age group. The pre-filled syringe or vial should be used instead for children 6 years of age and older and adolescents with psoriasis. The solution for infusion, pre-filled vial or syringe should be used instead for children weighing at least 40 kg with Crohn’s disease.

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

Other medicines, vaccines and Otulfi

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 Otulfi. • If you received Otulfi while pregnant, tell your baby’s doctor about your Otulfi 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 Otulfi 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

    Otulfi in pregnancy.

  • If you are a woman of childbearing potential, you are advised to avoid becoming pregnant and must use adequate contraception while using Otulfi and for at least 15 weeks after the last Otulfi treatment.
  • Ustekinumab can pass across the placenta to the unborn baby. If you received Otulfi 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 Otulfi 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 Otulfi 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 Otulfi - do not do both.

Driving and using machines

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

Otulfi contains polysorbate 80

This medicine contains 0.02 mg of polysorbate 80 in each pre-filled pen of 0.5 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 Otulfi

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

      Preparing for your injection Step 1

      • Choose a clean, flat surface, such as a

        table or countertop, in a well-lit area.

      • Gather the following supplies (not

        included) (see Figure A):

        • a sterile cotton ball or gauze
        • an alcohol pad
        • a sharps disposal container

          (see Step 9)

      • Remove the carton containing the OTULFI pre-filled pen from the

        refrigerator.

Before you start, check the carton to make sure that it is the right medicine and dose. You will have either a 45 mg dose or 90 mg dose as prescribed by your doctor.

  • If your dose is 45 mg, you will receive one 45 mg OTULFI pre-filled pen. - If your dose is 90 mg, you will receive either one 90mg OTULFI pre-

    filled pen or two 45 mg OTULFI pre-filled pens.

If you receive two 45 mg OTULFI pre-filled pens for a 90 mg dose:

  • Follow Steps 1 through 7 for both injections.
  • Choose two different sites for these injections (for example one

    injection in the right thigh and the other injection in the left thigh) and give the injections one right after the other.

  • Check the carton to make sure that it

    is the medicine and dose that you are

    prescribed.

  • Check the expiration date (EXP) on the

    carton to make sure the date has not

    passed (see Figure B).

  • Check the carton for any signs of

    damage.

Do not use the OTULFI pre-filled pen if it looks

like the carton has been opened.

  • Let the carton sit on the chosen surface

    for 45 minutes before use to allow the

    medicine in the OTULFI pre-filled pen to

    reach room temperature (see Figure C).

Do not warm OTULFI pre-filled pen in any

other way, such as in a microwave, hot water, or direct sunlight.

  • Remove the OTULFI pre-filled pen from carton.

Do not remove the clear cap from the OTULFI pre-filled pen until you are ready to inject to avoid injury.

Check your OTULFI pre-filled pen Step 2

  • Check the OTULFI pre-filled pen to make

    sure it is not cracked or damaged (see

    Figure D).

    Note: It is normal to see the purple

    indicator partially visible in the viewing

    window.

    Do not use if the OTULFI pre-filled pen shows signs of damage or if it has been dropped.

  • Check the OTULFI pre-filled pen label to make sure that:

    • The name on the pre-filled pen says OTULFI. - The dose on the OTULFI pre-filled pen

      is what you are prescribed.

    • The expiration date (EXP) on the

      OTULFI pre-filled pen has not passed

      (see Figure E).

Do not use the pre-filled pen if the name

on the label is not OTULFI, the dose is not what you are prescribed, or the expiration date on the label has passed.

  • Look at the medicine in the viewing

    window. Make sure it is clear and

    colourless to slightly brown-yellow

    and does not contain any particles (see

    Figure F).

    Note: Air bubbles in the medicine are

    normal.

    Do not inject OTULFI if the medicine is frozen, cloudy, discoloured, or has lumps or particles in it because it may not be safe to use. Call your doctor or pharmacist for instructions.

    Wash your hands Step 3

  • Wash your hands well with soap and

    water, then dry them with a clean towel

    (see Figure G).

    Choose the injection site Step 4

  • If you are giving yourself the injection,

    you can use:

    • The front of your upper thigh.
    • The belly (abdomen), except within

      5 cm around the belly button (navel).

    • If a caregiver is giving the injection,

      they can also use the outer area of

      the upper arm (see Figure H).

Note: Rotate to a different injection site

(such as other leg, other side of the belly,

etc.) for every injection.

Do not inject into skin that is sore (tender), bruised, red, or hard.

Do not inject through clothing.

Clean the injection site Step 5

  • Wipe the skin where you want to inject

    with an alcohol pad to clean it (see

    Figure I). Let the skin dry.

    Do not blow on or touch the site after

    cleaning.

    Give your injection Step 6

    When you are ready to inject, position the

    OTULFI pre-filled pen in your hand so you can

    clearly see the viewing window

    Using your other hand, firmly pull the clear cap

    straight off without twisting (see Figure J).

    Note: A few drops of medicine may come out

    of the needle, this is normal.

    Note: Use the OTULFI pre-filled pen within 3 minutes after removing the clear cap to avoid contamination.

    Do not try to put the clear cap back on the OTULFI pre-filled pen at any time, even at the end of the injection.

    Do not touch the needle cover (the purple-coloured part located at the tip of the OTULFI pre-filled pen) because this might cause an accidental needle stick.

    • Throw away the clear cap in a sharps disposal container

      (see Step 9).

Read all of the remaining instructions in Step 6 before you start injecting to make sure you give the full dose.

  • Place the purple needle cover of the

    OTULFI pre-filled pen straight against

    your skin at a 90-degree angle. Make sure

    that you can see the viewing window (see

    Figure K).

    Note: To make sure you inject under the

    skin (into the fatty tissue) do not tilt the

    OTULFI pre-filled pen.

  • In a single motion, push and hold the

    OTULFI pre-filled pen firmly against your

    skin until you hear a first click. This

    means the injection has started (see

    Figure L).

  • Look at the viewing window to make sure

    that the purple indicator is moving during

    the injection.

  • Continue pushing the OTULFI pre-filled

    pen down on the injection site and listen

    for a second click which means that the

    injection is almost complete. This may

    take between 5 to 20 seconds (see

    Figure M).

    Do not lift the OTULFI pre-filled pen from

    the skin when you hear the second click

    because the medicine may not be fully

    injected.

  • After you hear the second click, continue

    holding the OTULFI pre-filled pen in place

    and slowly count to 5 (see Figure N).

  • While holding the OTULFI pre-filled pen

    in place, check to make sure the purple

    indicator has fully appeared in the viewing

    window and has stopped moving (see

    Figure O).

    Do not try to repeat the injection with

    a new OTULFI pre-filled pen if the purple indicator did not come all the way down during the injection or you believe you did not get a full injection. Call your doctor or pharmacist if this happens.

    Remove the OTULFI pre-filled pen from your skin

    Step 7

    • When the injection is complete, lift the

      OTULFI pre-filled pen straight away from your skin (see Figure P).

      Note: The purple needle cover will slide down and cover the needle.

      Do not put the clear cap back on the

      OTULFI pre-filled pen.

    • If you see blood on the injection site, press gauze or a cotton ball on the skin until the bleeding stops (see Figure Q).

      Do not rub the injection site.

    • Throw away your used OTULFI pre-filled pen as described in Step 9 and Figure R.

      If a second 45 mg injection is needed for a 90 mg dose, repeat Steps 1 through 7 Step 8
