“…10,12,[40][41][42][43][44] Pegfilgrastim-jmdb has been shown to have high analytical and functional similarity to pegfilgrastim, with similar structure, molecular mass, physicochemical characteristics, and G-CSF receptor binding affinity. 45,46 A phase I randomized equivalence trial concluded that pegfilgrastim-jmdb demonstrated similar pharmacokinetics, pharmacodynamics, and safety to pegfilgrastim in healthy volunteers. 40 In a multicenter randomized phase III efficacy and safety trial, patients with breast cancer receiving myelosuppressive chemotherapy with pegfilgrastim-jmdb support showed no difference in duration of severe neutropenia, time to absolute neutrophil count (ANC) nadir, duration of postnadir recovery, or treatment-related adverse events compared with patients receiving reference pegfilgrastim.…”
