A polemic in response to Hoggatt et al. (Int J Nanomedicine. 2015;10:2647-2652) is given.Hoggatt et al. described lipegfilgrastim as "lipegfilgrastim has an active substance that is similar to filgrastim, with similar pharmacokinetics, receptor binding affinity, safety and efficacy as pegfilgrastim" and did not give the correct indications for either filgrastim or lipegfilgrastim.However the authors believe lipegfilgrastim would be more accurately described as "glycopegylated, long-acting form of recombinant human filgrastim" and it is to be used for reducing the duration of neutropenia and the incidence of febrile neutropenia in adult patients treated with cytotoxic chemotherapy for malignancy.
