What Ocrevus is and what it is used for

What Ocrevus is 

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.

What Ocrevus is used for

Ocrevus is used to treat adults with:

  • Forest Multiple Sclerosis (RMS)
  • Early Primary Progressive Multiple Sclerosis (PPMS)

What is multiple sclerosis

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 defense system) malfunctions and attacks the protective layer (called the myelin sheath) around the nerve cells, and causes inflammation. Degradation of the myelin sheath prevents the nerves from functioning properly.

The symptoms of MS depend on which part of the central nervous system is affected and may include problems with walking and balance, weakness, numbness, double vision, blurred vision, coordination difficulties, and problems with the bladder.

  • In relapsing-remitting MS , the patient has repeated attacks with symptoms ( relapses ). The symptoms may appear suddenly, within a few hours or slowly over several days. The symptoms disappear or improve between relapses , but injuries can build up and lead to permanent disability.
  • In primary progressive MS , the symptoms usually worsen continuously after the onset of the disease.

How does Ocrevus work?

Ocrevus attaches to specific B cells, which are a type of white blood cell that is part of the immune system and is important in MS. Ocrevus seeks out and removes these specific B cells. This reduces inflammation and attacks on the myelin sheath, reduces the risk of having a relapse, and delays the development of your disease.

  • In relapsing- remitting MS (RMS) , Ocrevus helps to significantly reduce the number of attacks ( relapses ) and significantly delays the rate of development of the disease. Ocrevus also significantly increases the possibility that a patient has no signs of disease activity (changes in the brain, relapses and worsening of disability).
  • In primary progressive MS (PPMS) , Ocrevus helps to slow the rate of disease progression and reduce the deterioration of walking speed.

What you need to know before you get Ocrevus 

You must not be given Ocrevus:

  • if you are allergic to ocrelizumab or any of the other ingredients of this medicine (listed in section 6).
  • if you have an ongoing 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 taking Ocrevus.

Warnings and cautions

Talk to your doctor before receiving Ocrevus if any of the following apply to you. Your doctor may decide to postpone treatment with Ocrevus or you may not be able to get Ocrevus if:

  • you have an infection . Your doctor will wait until infection one has passed before receiving 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 starting treatment with Ocrevus, your doctor will check if you are at risk of getting hepatitis B infection . Patients who have had a hepatitis B‑ infection or are carriers of the hepatitis B‑ virus will be given a blood test and the doctor will monitor for signs of a hepatitis B‑ infection .
  • you have cancer or have had cancer before. Your doctor may decide to postpone treatment with Ocrevus.

Effect on the immune system:

  • Diseases that affect your immune system : if you have another disease that affects the immune system. Then maybe you can not get Ocrevus.
  • Medicines that affect your immune system : if you have ever taken, are taking or plan to take medicines that affect the immune system, such as cytotoxic drugs, medicines that weaken the immune system or other medicines used to treat MS. Your doctor may decide to postpone treatment with Ocrevus or to ask you to stop taking such medicines before starting treatment with Ocrevus. For further information, see below under the heading “Other medicines and Ocrevus”.

Reactions associated with infusion one

  • Reactions associated with infusion are the most common side effect of treatment with Ocrevus.
  • Tell your doctor or nurse immediately if you get any reaction in connection with infusion one (see section 4 for a list of reactions associated with infusion ). Reactions associated with infusion one may occur during infusion one or up to 24 hours after infusion one.
  • To reduce the risk of reactions associated with infusion one, your doctor will give you other medicines before each infusion of Ocrevus (see section 3) and you will be closely monitored during infusion one and for at least one hour after the end of the infusion .

Infection is

  • Tell your doctor before taking Ocrevus if you think you may have an infection . Your doctor will wait until infection has receded before receiving Ocrevus.
  • You can more easily get your infection when you are treated with Ocrevus. This is because the immune cells that Ocrevus attacks also help fight infection .
  • Before starting treatment with Ocrevus and before giving you a subsequent infusion , your doctor may ask you to take a blood test to check your immune system as your infection is more common in severe problems with your immune system.
  • If you are being treated with Ocrevus for primary progressive multiple sclerosis and you have difficulty swallowing, Ocrevus may increase the risk of severe pneumonia .
  • Tell your doctor or nurse immediately if you experience any of these signs of infection during or after treatment with Ocrevus:
    • fever or chills
    • cough that does not go away
    • herpes (such as cold sores, shingles or genital herpes).
  • Tell your doctor or nurse immediately if you think your MS is getting worse or if you are experiencing new symptoms . The reason for this is a very rare and life-threatening infection in the brain, so-called progressive multifocal leukoencephalopathy (PML) which can cause symptoms similar to those in MS. PML can occur in patients taking medicines similar to Ocrevus and other medicines used to treat MS.
  • Tell your partner or caregiver about your treatment with Ocrevus. They may notice symptoms of PML that you do not, e.g. memory gaps, difficulty thinking, difficulty walking, vision loss, changes in the way you speak, which your doctor may need to examine.

Vaccinations

  • Tell your doctor if you have recently received a vaccine or are likely to receive a vaccine in the near future.
  • During treatment with Ocrevus, you should not receive live or live attenuated vaccines (eg BCG tu vaccine against tuberculosis or vaccine against yellow fever).
  • Your doctor may recommend that you be vaccinated against seasonal flu.
  • Your doctor will check if you need any vaccinations before starting treatment with Ocrevus. All vaccinations should be given at least 6 weeks before starting treatment with Ocrevus.

Children and young people

Ocrevus is not intended for use in children and adolescents under 18 years of age. This is because the drug has not been studied in this age group.

Other medicines and Ocrevus

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

You must tell your doctor about:

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

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

Pregnancy

  • Tell your doctor if you are pregnant, think you may be pregnant or are planning to have a baby, before you are given Ocrevus. This is because Ocrevus can pass 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 weigh the benefits of the treatment against the risks to your child.
  • Talk to your doctor before vaccinating your baby.
