BAVENCIO^®

Active ingredient: avelumab (rch)

Consumer Medicine Information (CMI)

This leaflet provides important information about using BAVENCIO. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using BAVENCIO.

Where to find information in this leaflet:

1. Why am I using BAVENCIO?

BAVENCIO contains the active ingredient, avelumab. BAVENCIO is a monoclonal antibody, which is a protein designed to recognise and attach to a specific target in the body to help the immune system attack and destroy cancer cells.

BAVENCIO is used to treat a rare type of skin cancer called metastatic Merkel cell carcinoma (mMCC) where the disease has spread; a type of cancer in the bladder or urinary tract called urothelial carcinoma, when the disease is advanced or metastatic but has not progressed with platinum-based chemotherapy; or a type of kidney cancer called renal cell carcinoma (RCC), when it is advanced, in combination with another medicine, axitinib. It is important that you also read the Consumer Medicine Information for axitinib. If you have any questions about axitinib, ask your doctor.

2. What should I know before I use BAVENCIO?

Warnings

Do not use BAVENCIO if:

• you are allergic to avelumab, or any of the ingredients listed at the end of this leaflet.
• Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

• have any other medical conditions, including an autoimmune disease (a condition where the body attacks its own cells) like Crohn's, Guillain- Barré, ulcerative colitis or lupus. If you already have an autoimmune disease, your risk of immune-mediated side effects may be higher as BAVENCIO may cause inflammation in parts of your body. You may also experience frequent flares of your autoimmune disease, which in the majority of cases are mild; human immunodeficiency virus (HIV) infection or acquired immune deficiency syndrome (AIDS); hepatitis B or hepatitis C; have had an organ transplant
• take any medicines for any other condition, including medicines that suppress your immune system

Once you are treated with BAVENCIO, your doctor may give you corticosteroids to reduce any possible side effects that you may have during your treatment.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Talk to your doctor or nurse before receiving BAVENCIO as it may cause:

• problems due to inflammation of your lungs (pneumonitis)
• problems with your liver (hepatitis or liver toxicity when used in combination with axitinib)
• problems with your intestines (colitis) or diarrhoea
• problems with your hormone producing glands (including the thyroid, pituitary, and adrenal glands)
• problems with your pancreas (pancreatitis)
• Type 1 diabetes, including a serious, sometimes life-threatening problem due to increased acid in the blood produced from diabetes (diabetic ketoacidosis).
• problems with your kidneys
• problems with your muscles (myositis, myasthenia gravis/myasthenic syndrome, polymyalgia rheumatica)
• problems with your bile ducts (sclerosing cholangitis)
• problems with your joints (arthritis)
• problems with your glands that make moisture for the body such as tears and saliva (Sjögren’s syndrome)
• problems with your heart (myocarditis or major adverse cardiovascular events such as trouble breathing, chest discomfort, or swelling of lower legs or hands when used in combination with axitinib)
• problems with your eyes (uveitis)
• an immune system disorder that can cause nerve inflammation (Guillain-Barré Syndrome)
• infusion-related reactions

In addition, autoimmune haemolytic anaemia (headaches, short of breath, looking pale, and yellowing of the skin and/or eyes) and systemic inflammatory response syndrome (redness and swelling in the affected parts of your body, pain, loss of function of parts of your body, fatigue, fast heart rate, abnormal breathing, fever or low body temperature, shaking or chills, warm or clammy/sweaty skin, rash, confusion, agitation or other mental changes, loss of consciousness) have been reported with BAVENCIO or other products in this class (PD-1/PD-L1 blocking antibodies).

Should any of the above occur, your doctor may give you other medicines in order to prevent complications and reduce your symptoms; withhold the next dose of BAVENCIO; or stop your treatment with BAVENCIO altogether.

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

BAVENCIO must not be used during pregnancy as it may cause harm to your unborn baby.

Make sure you maintain adequate contraception during treatment and for at least one month after your last dose.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

It is unknown if BAVENCIO is passed into your breast milk. A risk to the breast-fed infant cannot be excluded.

You should not breastfeed during treatment and for at least one month after your last dose.

Use in children

For mMCC, the effectiveness of BAVENCIO in children under the age of 12 years has not been established.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with BAVENCIO and affect how it works.

These include medicines that make your immune system weak, such as steroids.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect BAVENCIO.

4. How do I use BAVENCIO?

Prior to the first four infusions of BAVENCIO, you will be given paracetamol and an antihistamine. For subsequent infusions, these medicines will only be given if your doctor believe this is necessary. These premedications are given to help minimise potential reactions to the BAVENCIO infusion.

How much to use

• A doctor experienced in the use of medicines for cancer will supervise your treatment with BAVENCIO.
• Depending on your cancer, the recommended dose is either 10 mg per kg of your body weight or 800 mg of BAVENCIO.
• BAVENCIO has to be diluted with 0.9% or 0.45% saline solution before use.
• Your doctor will calculate the correct dose and dilution for you.

When to use BAVENCIO

• You will receive BAVENCIO as an infusion (a drip) into a vein (intravenously) over a period of 60 minutes, once every 2 weeks.
• Your doctor will decide how long you will receive BAVENCIO based on your response to the medicine and the type of cancer you have.

If you use too much BAVENCIO

As BAVENCIO is given to you under the supervision of your doctor, it is very unlikely that you will receive too much.

However, if you think that you have used too much BAVENCIO, you may need urgent medical attention.

You should immediately:

• phone the Poisons Information Centre
  (by calling 13 11 26), or
• contact your doctor, or
• go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using BAVENCIO?

Things you should do

Keep all appointments with your doctor so that your progress can be checked. Your doctor may do blood tests or other laboratory tests from time to time to prevent unwanted side effects during your treatment with BAVENCIO.

If you miss an appointment, talk to your doctor or nurse and arrange another visit as soon as possible.

Call your doctor straight away if you:

• Become pregnant while you are being treated with BAVENCIO

Remind any doctor, nurse, dentist or pharmacist you visit that you are using BAVENCIO.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how BAVENCIO affects you.

Treatment-related symptoms can affect your concentration and ability to react.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

Be aware of important symptoms of inflammation. BAVENCIO acts on your immune system and may cause inflammation in parts of your body. Inflammation may cause serious damage to your body and some inflammatory conditions may be life-threatening and need treatment or withdrawal of BAVENCIO.

Less serious side effects

Serious side effects

Tell your doctor or pharmacist if you notice anything else that may be making you feel unwell.

Other side effects not listed here may occur in some people.
