This is a summary of the European public assessment report (EPAR). It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the studies performed, to reach its recommendations on how to use the medicine.

- What is Tevagrastim?
Tevagrastim is a solution for injection or for infusion (drip into a vein). It contains the active substance filgrastim.
Tevagrastim is a ‘biosimilar’ medicine. This means that Tevagrastim is similar to a biological medicine that is already authorised in the European Union (EU) and contains the same active substance (also known as the ‘reference medicine’). The reference medicine for Tevagrastim is Neupogen.
- What is Tevagrastim used for?
Tevagrastim is used to stimulate the production of white blood cells in the following situations:
- to reduce the duration of neutropenia (low levels of neutrophils, a type of white blood cell) and the occurrence of febrile neutropenia (neutropenia with fever) in patients receiving chemotherapy (cancer treatment) that is cytotoxic (cell-killing);
- to reduce the duration of neutropenia in patients undergoing treatment to destroy bone-marrow cells before a bone-marrow transplant (such as in some patients with leukaemia) if they are at a risk of long-term, severe neutropenia;
- to increase levels of neutrophils and reduce the risk of infections in patients with neutropenia who have a history of severe, repeated infections;
- to treat persistent neutropenia in patients with advanced human immunodeficiency virus (HIV) infection, to reduce the risk of bacterial infections when other treatments are not appropriate.
Tevagrastim can also be used in patients who are about to donate blood stem cells for transplant, to help release these cells from the bone marrow.
The medicine can only be obtained with a prescription.
- How is Tevagrastim used?
Tevagrastim is given by injection under the skin or infusion into a vein. How it is given, the dose and the duration of treatment depend on why it is being used, the patient’s body weight and the response to treatment. Tevagrastim is usually given in a specialised treatment centre, although patients who receive it by injection under the skin may inject themselves once they have been trained appropriately. For more information, see the package leaflet.
- How does Tevagrastim work?
The active substance in Tevagrastim, filgrastim, is very similar to a human protein called granulocyte-colony-stimulating factor (G-CSF). Filgrastim is produced by a method known as ‘recombinant DNA technology’: it is made by a bacterium that has received a gene (DNA), which makes it able to produce filgrastim. The replacement acts in same way as naturally produced G-CSF by encouraging the bone marrow to produce more white blood cells.
- How has Tevagrastim been studied?
Tevagrastim was studied to show that it is comparable to the reference medicine, Neupogen.
Tevagrastim was compared to Neupogen and to placebo (a dummy treatment) in one main study involving 348 patients with breast cancer. The study looked at the duration of severe neutropenia during the patients’ first cycle of cytotoxic chemotherapy.
To study the safety of Tevagrastim, two further studies were carried out in patients with lung cancer and with non-Hodgkin’s lymphoma.
- What benefit has Tevagrastim shown during the studies?
Treatment with Tevagrastim and Neupogen brought about similar reductions in duration of severe neutropenia. During the first 21-day chemotherapy cycle, patients treated with either Tevagrastim or Neupogen had severe neutropenia for an average of 1.1 days, compared with 3.8 days in those receiving placebo. Therefore, the effectiveness of Tevagrastim was shown to be equivalent to that of Neupogen.
- What is the risk associated with Tevagrastim?
The most common side effect with Tevagrastim (seen in more than 1 patient in 10) is musculoskeletal pain (pain in the muscles and bones). Other side effects may be seen in more than 1 patient in 10, depending on the condition that Tevagrastim is being used for. For the full list of all side effects reported with Tevagrastim, see the package leaflet.
Tevagrastim should not be used in people who may be hypersensitive (allergic) to filgrastim or any of the other ingredients.
- Why has Tevagrastim been approved?
The Committee for Medicinal Products for Human Use (CHMP) decided that, in accordance with EU requirements, Tevagrastim has been shown to have a comparable quality, safety and efficacy profile to Neupogen. Therefore, the CHMP’s view was that, as for Neupogen, the benefit outweighs the identified risk. The Committee recommended that Tevagrastim be given marketing authorisation.

Tevagrastim is indicated for the reduction in the duration of neutropenia and the incidence of febrile neutropenia in patients treated with established cytotoxic chemotherapy for malignancy (with the exception of chronic myeloid leukaemia and myelodysplastic syndromes) and for the reduction in the duration of neutropenia in patients undergoing myeloablative therapy followed by bone-marrow transplantation considered to be at increased risk of prolonged severe neutropenia. The safety and efficacy of filgrastim are similar in adults and children receiving cytotoxic chemotherapy.
Tevagrastim is indicated for the mobilisation of peripheral blood progenitor cells (PBPC).
In patients, children or adults, with severe congenital, cyclic, or idiopathic neutropenia with an absolute neutrophil count (ANC) of 0.5 x 109/l, and a history of severe or recurrent infections, long term administration of Tevagrastim is indicated to increase neutrophil counts and to reduce the incidence and duration of infection-related events.
Tevagrastim is indicated for the treatment of persistent neutropenia (ANC less than or equal to 1.0 x 109/l) in patients with advanced HIV infection, in order to reduce the risk of bacterial infections when other options to manage neutropenia are inappropriate.
