What is Avelumab and why am I having it?
Avelumab is a treatment which helps your immune system to attack and destroy cancer cells. Avelumab is used to treat your type of cancer, but it is not a chemotherapy drug.
How often will I receive Avelumab?
For this treatment to be most effective, it is given at specific time intervals. Avelumab is given every 2 weeks. Your doctor will discuss with you how long you will have to continue having the treatment.
How often will I see the specialist team?
You will need to be seen in the outpatient clinic before each treatment. At each outpatient clinic the medical team who prescribes your Avelumab will check how you are feeling and discuss any problems you may have.
You will have regular blood tests and we will check how you are feeling and discuss any problems you may have. This is so we can check how the treatment is affecting you. If your blood results are satisfactory, your treatment will be given.
How is Avelumab given?
Avelumab is given through a drip into a vein in the back of your hand or arm.
Where will my treatment be given?
The treatments will be given in the day case treatment areas at Velindre.
How long will I be in the hospital?
The Avelumab treatment is given over 1 hour, however please allow approximately 2 hours for your appointment.
Can I bring relatives and friends with me?
You are welcome to bring someone to stay with you during your treatment. Space is limited so there is not usually room for more than one person. Treatment areas are not suitable for young children.
Reactions during the treatment
If you experience any of the following during the treatment please tell your nurse straight away:
If any of these occur we will slow down or stop the Avelumab until you feel better. The treatment can then start again, usually without any further problems.
What are the possible side effects?
Some people have very few side effects whilst others may experience more. Most of the side effects happen because Avelumab affects the immune system causing inflammation of other parts of the body such as the skin, the bowels and hormone producing glands. Most, if not all severe side effects can be controlled by the use of steroid medication immediately either as tablets or through a drip. Hospital admission may become necessary sometimes, however, for severe immune related reactions.
Mostly side effects are mild and can be easily managed at home. But it is important that if you have more severe side effects that you contact Velindre Cancer Centre. The telephone number is at the end of the leaflet. Further details of when to contact Velindre are included in the individual side effects listed below.
Effects on the bowels
This treatment has been known to cause either constipation or diarrhoea.
Please note:
If you have any of the symptoms below you must inform Velindre Cancer Centre immediately, the telephone numbers are at the end of the leaflet.
There is a risk of inflammation of the bowel (colitis) or rupture of the bowel (perforation) in a small minority of patients.
Loss of appetite and weight loss
You may experience a loss of appetite and some people may feel sick whilst taking Avelumab but this can usually be well controlled with anti sickness medication. If you are sick more than once in 24 hours despite taking regular anti-sickness medicine, you should contact Velindre Cancer Centre for advice. The telephone number is at the end of the leaflet. You may experience weight loss with Avelumab.
Tiredness and fatigue
Avelumab can make you feel more tired than usual. It is important to listen to your body and rest if you need to, but carry out your normal activities if you feel able. Some people find it beneficial to take gentle exercise as well as taking rest. If you are sleeping more than 50% during the daytime you need to contact Velindre Cancer Centre on the treatment helpline. The telephone number is at the end of the leaflet.

Avelumab can cause you to become anaemic. Your team will monitor your bloods to check for anaemia. If you experience fatigue or shortness of breath on exertion, inform your team.

Blood Clots
A diagnosis of cancer can increase your risk of developing a blood clot (thrombosis), and having cancer treatment may increase this risk further. It is important to tell your doctor immediately if you have symptoms such as pain, redness and swelling in your leg, or breathlessness and chest pain.
Blood clots can be very serious. However, most clots can usually be successfully treated with drugs to thin the blood. Your doctor or nurse can give you more information.
Other information
It is important you do not become pregnant, breastfeed or father a child whilst having Avelumab treatment and for at least 1 month after treatment is completed.
Side effects may continue for up to 6 months after treatment. If you have any side effects contact your consultant. If you are admitted to hospital or see your GP during this period, inform the doctor you have had Avelumab, an immune therapy.
Sometimes cancer drugs can have very serious side effects which can be life threatening. It is important to inform Velindre cancer centre if you are concerned about any side-effects.
