Richter Announces Withdrawal of its Marketing Authorisation Application for Efgratin (biosimilar pegfilgrastim)


Gedeon Richter Plc. (“Richter”) announced today that it has withdrawn its Application for a Marketing Authorisation (MAA) from the European Medicines Agency (EMA) for Efgratin, its biosimilar pegfilgrastim.

This withdrawal occurred subsequent to a MAA resubmission, which was based on completion of an additional clinical study.

The decision to withdraw the MAA was taken because Richter could not address the CHMP concerns within the given timeframe.

The Company reserves the right to make further submissions at a future date in this or other therapeutic indication(s).


About biosimilars

A biosimilar is a biological medicine similar to another biological medicine (the 'reference medicine') that is already authorised in the EU. The biosimilar medicines do not have any significant differences from the reference medicine in terms of quality, safety or efficacy.

About pegfilgrastim

Pegfilgrastim, a pegylated recombinant, human granulocyte-colony stimulating factor is 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 (neutropenia accompanied by fever).
