Ocrevus contains the active substance ‘ocrelizumab’. It is a type of protein called a ‘monoclonal antibody’. Antibodies work by attaching to specific targets in your body.

Ocrevus is used to treat adults with:

• Relapsing forms of multiple sclerosis (RMS)
• Early primary progressive multiple sclerosis (PPMS)

Multiple Sclerosis (MS) affects the central nervous system, especially the nerves in the brain and spinal cord. In MS, the immune system (the body’s defence system) works incorrectly and attacks a protective layer (called myelin sheath) around nerve cells and causes inflammation. Breakdown of the myelin sheath stops the nerves working properly.

Symptoms of MS depend on which part of the central nervous system is affected and can include problems with walking and balance, weakness, numbness, double vision and blurring, poor coordination and bladder problems.

• In relapsing forms of MS, the patient has repeated attacks of symptoms (relapses). The symptoms can appear suddenly within a few hours, or slowly over several days. The symptoms disappear or improve between relapses but damage may build up and lead to permanent disability.
• In primary progressive MS, the symptoms generally continue to worsen from the start of the disease.

Ocrevus attaches to specific B cells, which are a type of white blood cells that are part of the immune system and play a role in MS. Ocrevus targets and removes those specific B cells. This reduces inflammation and attacks on the myelin sheath, reduces the chance of having a relapse and slows the progression of your disease.

• In Relapsing forms of MS (RMS), Ocrevus helps to significantly reduce the number of attacks (relapses) and significantly slow down the progression of the disease. Ocrevus also significantly increases the chance of a patient having no evidence of disease activity (brain lesions, relapses and worsening of disability).
• In Primary Progressive MS (PPMS), Ocrevus helps to slow down the progression of the disease and reduce deterioration in walking speed.

• if you are allergic to ocrelizumab or any of the other ingredients of this medicine (listed in section 6).
• if you currently have an infection.
• if you have been told that you have severe problems with your immune system.
• if you have cancer.

If you are not sure, talk to your doctor before you are given Ocrevus.

Talk to your doctor before you are given Ocrevus if any of the following apply to you. Your doctor may decide to delay your treatment with Ocrevus, or may decide you cannot receive Ocrevus if:

• you have an infection. Your doctor will wait until the infection is resolved before giving you Ocrevus.
• you have ever had hepatitis B or are a carrier of the hepatitis B virus. This is because medicines like Ocrevus can cause the hepatitis B virus to become active again. Before your Ocrevus treatment, your doctor will check if you are at risk of hepatitis B infection. Patients who have had hepatitis B or are carriers of the hepatitis B virus will have a blood test and will be monitored by a doctor for signs of hepatitis B infection.
• you have cancer or if you have had cancer in the past. Your doctor may decide to delay your treatment with Ocrevus.

• Diseases that affect your immune system: if you have another disease which affects the immune system. You may not be able to receive Ocrevus.
• Medicines that affect your immune system: if you have ever taken, are taking or are planning to take medicines that affect the immune system – such as chemotherapy, immunosuppressants or other medicines used to treat MS. Your doctor may decide to delay your treatment with Ocrevus or may ask you to stop such medicines before starting treatment with Ocrevus. See under ‘Other medicines and Ocrevus’, below for more information.

• Infusion-related reactions are the most common side effect of Ocrevus treatment.
• Tell your doctor or nurse straight away if you have any infusion-related reaction (see section 4 for a list of infusion-related reactions). Infusion-related reactions can happen during the infusion or up to 24 hours after the infusion.
• To reduce the risk of infusion-related reaction, your doctor will give you other medicines before each infusion of Ocrevus (see section 3) and you will be closely monitored during the infusion and for at least one hour after the infusion has been given.

• Talk to your doctor before you are given Ocrevus if you think you have an infection. Your doctor will wait until the infection is resolved before giving you Ocrevus.
• You might get infections more easily with Ocrevus. This is because the immune cells that Ocrevus targets also help to fight infection.
• Before you start treatment with Ocrevus and before subsequent infusions, your doctor may ask you to have a blood test to verify your immune system because infections may occur more frequently in case of severe problems with your immune system.
• If you are treated with Ocrevus for primary progressive multiple sclerosis, and you have swallowing difficulties, Ocrevus may increase the risk of severe pneumonia.
• Tell your doctor or nurse straight away if you have any of these signs of infection during or after Ocrevus treatment:
  • fever or chills
  • cough that does not go away
  • herpes (such as cold sore, shingles or genital sores).
• Tell your doctor or nurse straight away if you think your MS is getting worse or if you notice any new symptoms. This is because of a very rare and life-threatening brain infection, called ‘progressive multifocal leukoencephalopathy’ (PML), which can cause symptoms similar to those of MS. PML can occur in patients taking Ocrevus.
  Tell your partner or carer about your Ocrevus treatment. They might notice symptoms of PML that you do not, such as memory lapses, trouble thinking, difficulty walking, sight loss, changes in the way you talk, which your doctor may need to investigate.

• Tell your doctor if you have recently been given any vaccine or might be given a vaccine in the near future.
• While you are being treated with Ocrevus, you should not be given live or live attenuated vaccines (for example BCG for tuberculosis or vaccines against yellow fever).
• Your doctor may recommend that you are given a seasonal influenza vaccine.
• Your doctor will check if you need any vaccinations before you start treatment with Ocrevus. Any vaccinations should be given at least 6 weeks before you start treatment with Ocrevus.

Ocrevus is not intended to be used in children and adolescents under 18 years old. This is because it has not yet been studied in this age group.

Tell your doctor if you are taking, have recently taken or might take any other medicines.

In particular tell your doctor if:

• you have ever taken, are taking or are planning to take medicines that affect the immune system – such as chemotherapy, immunosuppressants or other medicines used to treat MS. The effect on the immune system of these medicines with Ocrevus could be too strong. Your doctor may decide to delay your treatment with Ocrevus or may ask you to stop such medicines before starting treatment with Ocrevus.
• you are taking medicines for high blood pressure. This is because Ocrevus may lower blood pressure. Your doctor may ask you to stop taking your blood pressure medicines for 12 hours before each Ocrevus infusion.

If any of the above apply to you (or you are not sure), talk to your doctor before you are given Ocrevus.

• If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. This is because Ocrevus may cross the placenta and affect your baby.
• Do not use Ocrevus if you are pregnant unless you have discussed this with your doctor. Your doctor will consider the benefit of you taking Ocrevus against the risk to your baby.
• Talk to your doctor before vaccinating your baby.

Women who could become pregnant must use contraception:

• during treatment with Ocrevus and
• for 12 months after your last infusion of Ocrevus.

Do not breast-feed while you are being treated with Ocrevus. This is because Ocrevus may pass into breast milk.

It is not known whether Ocrevus can affect your ability to drive or use tools or machines.

Your doctor will tell you whether your MS may affect your ability to drive or use tools and machines safely.

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

Before you are given Ocrevus, you will receive other medicines to prevent or reduce possible side effects such as infusion-related reactions (see sections 2 and 4 for information about infusion-related reactions).

You will receive a corticosteroid and an anti-histamine before each infusion and you may also receive medicines to reduce fever.

You will be given a total dose of 600 mg of Ocrevus every 6 months.

• The first 600 mg dose of Ocrevus will be given as 2 separate infusions (300 mg each), given 2 weeks apart. Each infusion will last about 2 hours 30 minutes.
• The next 600 mg doses of Ocrevus will be given as a single infusion. Depending on the rate of the subsequent infusion, each infusion will either last about 3 hours 30 minutes or 2 hours.

• Ocrevus will be given to you by a doctor or a nurse. It will be given as an infusion into a vein (intravenous infusion or IV infusion).
• You will be closely monitored while you are being given Ocrevus and for at least 1 hour after the infusion has been given. This is in case you have any side effects such as infusion-related reactions. The infusion may be slowed, temporarily stopped or permanently stopped if you have an infusion-related reaction, depending on how serious it is (see sections 2 and 4 for information about infusion-related reactions).

• If you miss an infusion of Ocrevus, talk to your doctor to arrange to have it as soon as possible. Do not wait until your next planned infusion.
• To get the full benefit of Ocrevus, it is important that you receive each infusion when it is due.

• It is important to continue your treatment for as long as you and your doctor decide that it is helping you.
• Some side effects can be related to having low B cells. After you stop Ocrevus treatment, you may still experience side effects until your B-cells return to normal. Your blood B-cells will gradually increase to normal levels. This can take from six months to two and a half years, or up to several years in rare cases.
• Before you start any other medicines, tell your doctor when you had your last Ocrevus infusion.

Infusion-related reactions

• Infusion-related reactions are the most common side effect of Ocrevus treatment (very common: may affect more than 1 in 10 people). In most cases these are mild reactions but some serious reactions can happen.
• Tell your doctor or nurse straight away if you experience any signs or symptoms of an infusion-related reaction during the infusion or up to 24 hours after the infusion.
  Symptoms can include, but are not limited to:
  • itchy skin
  • rash
  • hives
