Patient leaflet - Omvoh 100 mg solution for injection in Pre-filled syringe

1. What Omvoh is and what it is used for

Omvoh contains the active substance mirikizumab, a monoclonal antibody. Monoclonal antibodies are proteins that recognise and bind specifically to certain target proteins in the body. Omvoh works by attaching to and blocking a protein in the body called IL-23 (interleukin-23), which is involved in inflammation. By blocking the action of IL-23, Omvoh reduces inflammation and other symptoms associated with ulcerative colitis.

Ulcerative colitis

Ulcerative colitis is a chronic inflammatory disease of the large bowel. If you have ulcerative colitis, you will first be given other medicines. If you do not respond well enough or cannot tolerate these medicines, you may be given Omvoh to reduce signs and symptoms of ulcerative colitis such as diarrhoea, abdominal pain, urgency and rectal bleeding.

2. What you need to know before you use Omvoh

Do not use Omvoh

  • if you are allergic to mirikizumab or any of the other ingredients of this medicine (listed in section 6). If you think you may be allergic, ask your doctor for advice before using Omvoh.
  • If you have important active infections (active tuberculosis).

Warnings and precautions

  • Talk to your doctor or pharmacist before using this medicine.
  • Your doctor will check how well you are before treatment.
  • Make sure you tell your doctor about any illness you have before treatment.

Infections

  • Omvoh can potentially cause serious infections. Treatment with Omvoh should not be started if you have an active infection until the infection is gone.
  • After starting the treatment, tell your doctor right away if you have any symptoms of an infection such as:

    • fever o shortness of breath
    • chills o runny nose
    • muscle aches o sore throat
    • cough o pain during urination
  • Also tell your doctor if you have recently been near anyone who might have tuberculosis.
  • Your doctor will examine you and may do a test for tuberculosis before you have Omvoh.
  • If your doctor thinks you are at risk of an active tuberculosis, you may be given medicines to treat it.

Vaccinations

Your doctor will check to see if you need any vaccinations before starting treatment. Tell your doctor, pharmacist or nurse if you have recently had or are going to have a vaccination. Some types of vaccines (live vaccines) should not be given while using Omvoh.

Allergic reactions

  • Omvoh can potentially cause serious allergic reactions.
  • Stop using Omvoh and get emergency medical help right away if you develop any of the following symptoms of a serious allergic reaction:

    • rash o low blood pressure
    • fainting o swelling of the face, lips, mouth, tongue or throat, trouble breathing
    • dizziness o sensation of throat tightening or chest tightness.

Liver blood test

Your doctor will conduct blood tests before starting and during treatment with Omvoh to check if your liver is functioning normally. If blood tests are abnormal, your doctor might interrupt therapy with Omvoh and do additional tests on your liver to determine the cause.

Children and adolescents

Omvoh is not recommended for children and adolescents under 18 years of age because it has not been studied in this age group.

Other medicines and Omvoh

Tell your doctor, pharmacist or nurse

  • if you are using, have recently used or might use 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 Omvoh.

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 using this medicine. It is preferable to avoid the use of Omvoh in pregnancy. The effects of Omvoh in pregnant women are not known. If you are a woman of childbearing potential, you are advised to avoid becoming pregnant and should use effective contraception while using Omvoh and for at least 10 weeks after the last Omvoh dose.

If you are breast-feeding or are planning to breast-feed, talk to your doctor before using this medicine.

Driving and using machines

Omvoh is unlikely to influence your ability to drive and use machines.

Omvoh contains sodium

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

Omvoh contains polysorbate

This medicine contains 0.3 mg/mL of polysorbate 80 in each syringe which is equivalent to 0.6 mg for the maintenance dose to treat ulcerative colitis. Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.

3. How to use Omvoh

Always use this medicine exactly as your doctor or nurse has told you. Check with your doctor, nurse or pharmacist if you are not sure how to use this medicine.

How much Omvoh is given and for how long

Your doctor will decide how much Omvoh you need and for how long. Omvoh is for long-term treatment. Your doctor or nurse will regularly monitor your condition to check that the treatment is having the desired effect.

Ulcerative colitis

  • Treatment start: The first dose of Omvoh is 300 mg and will be given by your doctor by intravenous infusion (drip in a vein in your arm) over at least 30 minutes. After the first dose, you will receive another dose of Omvoh 300 mg 4 weeks later and again after an additional 4 weeks.

    If you do not have adequate therapeutic response after these 3 infusions, your doctor might consider continuing intravenous infusions at weeks 12, 16 and 20.

  • Maintenance therapy: 4 weeks after the last intravenous infusion, a maintenance dose of Omvoh 200 mg will be given by an injection under the skin (‘subcutaneously’) and then every 4 weeks. The maintenance dose of 200 mg will be given by using 2 injections each containing 100 mg of Omvoh.

    If you lose response after receiving the maintenance dose of Omvoh, your doctor may decide to give you 3 doses of Omvoh by intravenous infusions.

    Your doctor or nurse will tell you when to switch to subcutaneous injections. During maintenance therapy you and your doctor or nurse should decide if you should inject Omvoh yourself after training in subcutaneous injection technique. It is important not to try to inject yourself until you have been trained by your doctor or nurse. Your doctor or nurse will offer the necessary training.

    A caregiver may also give you your Omvoh injection after proper training. Use a reminder method such as notes in a calendar or diary to help you remember when to take your next dose so that you avoid missing or repeating doses.

If you receive more Omvoh than you should

If you have received more Omvoh than you should or the dose has been given sooner than prescribed, inform your doctor.

If you forget to use Omvoh

If you have forgotten to inject a dose of Omvoh, inject as soon as possible. Thereafter, resume dosing every 4 weeks.

If you stop using Omvoh

You should not stop using Omvoh without speaking to your doctor first. If you stop treatment, symptoms of ulcerative colitis may come back.

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