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.

Filgrastim Hexal is a solution for injection or infusion (drip into a vein) in a prefilled syringe. It contains the active substance filgrastim (30 or 48 million units).
Filgrastim Hexal is a ‘biosimilar medicine'. This means that Filgrastim Hexal 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 Filgrastim Hexal is Neupogen.
Filgrastim Hexal is used to stimulate the production of white blood cells in the following situations:
Filgrastim Hexal can also be used in people 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.
Filgrastim Hexal 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. Filgrastim Hexal 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.
The active substance in Filgrastim Hexal, 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 the same way as naturally produced G-CSF by encouraging the bone marrow to produce more white blood cells.
Filgrastim Hexal was studied to show that it is comparable to the reference medicine, Neupogen.
Four studies looked at the levels of neutrophils in the blood in a total of 146 healthy volunteers who received Filgrastim Hexal or Neupogen. The studies looked at the effects of single and repeated administration of various doses of the medicines, either injected under the skin or infused into a vein. The main measure in these studies was the neutrophil count over the first 10 days of treatment.
Filgrastim Hexal and Neupogen brought about similar increases in blood neutrophil counts in healthy volunteers over the course of the studies. This was considered sufficient to demonstrate that the benefits of Filgrastim Hexal are comparable to those of the reference medicine.
The most common side effect with Filgrastim Hexal (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 Filgrastim Hexal is being used for. For the full list of all side effects reported with Filgrastim Hexal, see the package leaflet.
Filgrastim Hexal should not be used in people who may be hypersensitive (allergic) to filgrastim or any of the other ingredients.
The Committee for Medicinal Products for Human Use (CHMP) decided that, in accordance with EU requirements, Filgrastim Hexal 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 Filgrastim Hexal be given marketing authorisation.
The European Commission granted a marketing authorisation valid throughout the EU for Filgrastim Hexal to Hexal AG on 6 February 2009.
