Overview
Pelmeg is a medicine used in cancer patients to help with neutropenia (low levels of neutrophils, a type of white blood cell), which is a common side effect of cancer treatment and can leave patients vulnerable to infections.
It is given specifically to reduce the duration of neutropenia and prevent febrile neutropenia (when neutropenia is accompanied by fever).
Pelmeg is not intended for use in patients with the blood cancer chronic myeloid leukaemia or with myelodysplastic syndromes (conditions in which large numbers of abnormal blood cells are produced, which can develop into leukaemia).
Pelmeg is a ‘biosimilar medicine’. This means that Pelmeg is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Pelmeg is Neulasta.
Pelmeg can only be obtained with a prescription and treatment should be started and supervised by a doctor who has experience in the treatment of cancer or blood disorders. It is available as a prefilled syringe containing a solution for injection under the skin. Pelmeg is given as a single dose of 6 mg injected under the skin at least 24 hours after the end of each cycle of chemotherapy (treatment with cancer medicines). Patients can inject themselves if they have been trained appropriately.
For more information about using Pelmeg, see the package leaflet or contact your doctor or pharmacist.
The active substance in Pelmeg, pegfilgrastim, is a form of filgrastim, which is very similar to a human protein called granulocyte-colony-stimulating factor (G-CSF). Filgrastim works by encouraging the bone marrow to produce more white blood cells, increasing white blood cell counts and so treating neutropenia.
Filgrastim has been available in other medicines in the European Union (EU) for a number of years. In Pelmeg, filgrastim has been ‘pegylated’ (attached to a chemical called polyethylene glycol). This slows down the removal of filgrastim from the body, allowing the medicine to be given less often.
Laboratory studies comparing Pelmeg with Neulasta have shown that the active substance in Pelmeg is highly similar to that in Neulasta in terms of structure, purity and biological activity. Studies have also shown that giving Pelmeg produces similar levels of the active substance in the body to giving Neulasta.
Because Pelmeg is a biosimilar medicine, the studies on effectiveness and safety of pegfilgrastim carried out with Neulasta do not all need to be repeated for Pelmeg.
The safety of Pelmeg has been evaluated, and on the basis of all the studies carried out the side effects of the medicine are considered to be comparable to those of the reference medicine Neulasta. The most common side effect with Pelmeg (which may affect more than 1 in 10 people) is pain in the bones. Pain in muscles is also common. For the full list of side effects and restrictions with Pelmeg, see the package leaflet.
The European Medicines Agency decided that, in accordance with EU requirements for biosimilar medicines, Pelmeg has a highly similar structure, purity and biological activity to Neulasta and is distributed in the body in the same way.
All these data were considered sufficient to conclude that Pelmeg will behave in the same way as Neulasta in terms of effectiveness and safety in its authorised uses. Therefore, the Agency’s view was that, as for Neulasta, the benefit of Pelmeg outweighs the identified risk and it can be authorised for use in the EU.
Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Pelmeg have been included in the summary of product characteristics and the package leaflet.
As for all medicines, data on the use of Pelmeg are continuously monitored. Side effects reported with Pelmeg are carefully evaluated and any necessary action taken to protect patients.
Pelmeg received a marketing authorisation valid throughout the EU on 20 November 2018.
