About

This is a summary of the European public assessment report (EPAR) for Blitzima. It explains how the Agency assessed the medicine to recommend its authorisation in the EU and its conditions of use. It is not intended to provide practical advice on how to use Blitzima.

For practical information about using Blitzima, patients should read the package leaflet or contact their doctor or pharmacist.

What is Blitzima and what is it used for?

Blitzima is a medicine used in adults to treat the following blood cancers and inflammatory conditions:

  • follicular lymphoma and diffuse large B cell non-Hodgkin’s lymphoma (two types of non-Hodgkin’s lymphoma, a blood cancer);
  • chronic lymphocytic leukaemia (CLL, another blood cancer affecting white blood cells);
  • granulomatosis with polyangiitis (GPA or Wegener’s granulomatosis) and microscopic polyangiitis (MPA), which are inflammatory conditions of the blood vessels.

Depending on the condition it is used to treat, Blitzima may be given with chemotherapy (other cancer medicines) or medicines used for inflammatory disorders (corticosteroids). Blitzima contains the active substance rituximab.

Blitzima is a ‘biosimilar medicine’. This means that Blitzima is highly similar to a biological medicine (also known as the ‘reference medicine’) that is already authorised in the European Union (EU).

How is Blitzima used?

Blitzima can only be obtained with a prescription. It is available as a concentrate for making a solution that must be given by infusion (drip) into a vein. Before each infusion, the patient should be given an antihistamine (to prevent allergic reactions) and an anti-pyretic (a medicine to reduce fever). Blitzima should be given under the close supervision of an experienced healthcare professional and in a place where facilities for resuscitating patients are immediately available.

For further information, see the package leaflet.

How does Blitzima work?

The active substance in Blitzima, rituximab, is a monoclonal antibody (a type of protein) designed to recognise and attach to a protein called CD20 present on the surface of B cells (types of white blood cells). When rituximab attaches to CD20, it causes the death of B cells, which helps in lymphoma and CLL, where B cells have become cancerous. In GPA and MPA, destroying the B cells lowers the production of antibodies thought to play an important role in attacking the blood vessels and causing inflammation.

What benefits of Blitzima have been shown in studies?

Laboratory studies comparing Blitzima with MabThera have shown that the active substance in Blitzima is highly similar to that in MabThera in terms of structure, purity and biological activity. Studies have also shown that giving Blitzima produces similar levels of the active substance in the body to giving MabThera.

In addition, Blitzima has been compared with MabThera given into a vein in a main study involving 372 patients with active rheumatoid arthritis (an inflammatory disease). The study showed that Blitzima and MabThera had comparable effects on arthritis symptoms: after 24 weeks, the proportion of patients with a 20% improvement in symptom score (called ACR20) was 74% (114 of 155 patients) with Blitzima and 73% (43 of 59 patients) with MabThera.

Further evidence came from supportive studies, including one involving 121 patients with advanced follicular lymphoma, where adding Blitzima to chemotherapy medicines was at least as effective as adding Rituxan, the US version of MabThera. In this study improvement was seen in 96% of cases (67 of 70 patients) with Blitzima and 90% (63 of 70 patients) with Rituxan.

Because Blitzima is a biosimilar medicine, the studies on effectiveness and safety of rituximab carried out with MabThera do not all need to be repeated for Blitzima.

What are the risks associated with Blitzima?

The most common side effects with rituximab are reactions related to the infusion (such as fever, chills and shivering) which occur in most cancer patients and in more than 1 in 10 GPA or MPA patients at the time of the first infusion. The risk of such reactions decreases in subsequent infusions. The most common serious side effects are infusion reactions, infections and, in cancer patients, heart-related problems. Other serious side effects include hepatitis B reactivation (return of previous active liver infection with hepatitis B virus) and a rare and severe brain infection known as progressive multifocal leukoencephalopathy (PML). For the full list of side effects reported with Blitzima, see the package leaflet.

Blitzima must not be used in people who are hypersensitive (allergic) to rituximab, mouse proteins or any of the other ingredients. It must also not be used in patients with a severe infection or a severely weakened immune system. Patients with GPA or MPA must also not receive Blitzima if they have severe heart problems.

Why is Blitzima approved?

The European Medicines Agency decided that, in accordance with EU requirements for biosimilar medicines, Blitzima has a highly similar structure, purity and biological activity to MabThera and is distributed in the body in the same way. In addition, a study comparing Blitzima to MabThera in patients with rheumatoid arthritis (which can support its use in other inflammatory disorders such as GPA and MPA) showed that both medicines are similarly effective, and a supportive study in follicular lymphoma showed effectiveness in cancer. Thus, all these data were considered sufficient to conclude that Blitzima will behave in the same way in terms of effectiveness as MabThera in its approved indications. Therefore, the Agency’s view was that, as for MabThera, the benefit outweighs the identified risk and it recommended that Blitzima be given marketing authorisation.

What measures are being taken to ensure the safe and effective use of Blitzima?

The company that markets Blitzima will provide doctors and patients using the medicine for non-cancer conditions with educational material including information on the need to give the medicine where facilities for resuscitation are available and on the risk of infection, including PML. Patients are also to receive an alert card to carry at all times, instructing them to contact their doctor immediately if they have any of the listed symptoms of infection.

Doctors prescribing Blitzima for cancer will be provided with educational material reminding them of the need to use the medicine only by infusion into a vein.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Blitzima have also been included in the summary of product characteristics and the package leaflet.
