摘要

Lipegfilgrastim is a granulocyte colony-stimulating factor (G-CSF). In the European Union, it is authorised by subcutaneous administration for the prevention of neutropenia in patients receiving cytotoxic chemotherapy. In France, it has been available since the beginning of 2020. Proprietary medicinal products based on filgrastim (Neupogen° and other brands) or on pegfilgrastim (Neulasta° and other brands) were already available for use in this setting (1,2). Lipegfilgrastim and pegfilgrastim are pegylated forms of filgrastim, i.e. they are obtained by attaching a molecule of polyethylene glycol (PEG) to the filgrastim molecule (hence the addition of -peg- or peg- to their name). Pegylation reduces the rate of elimination of the drug by the body, hence prolonging its action (see also "Liposomal forms of drugs: now specified in the brand name, but no improvement to the INN" p. 48). This allows the number of injections of pegylated forms to be reduced compared to filgrastim, while having a similar effect (1,3,4). In lipegfilgrastim, the PEG molecule is attached to filgrastim via a glycan moiety, in contrast to pegfilgrastim. This slight difference in chemical structure led to the granting of a new international non-proprietary name (INN) for lipegfilgrastim, with the addition of the invented prefix li- to distinguish the two substances (1,4,5).
