Rolvedon (eflapegrastim-xnst) is now available to decrease the incidence of infection, as manifested by febrile neutropenia, in adults with nonmyeloid malignancies receiving myelosuppressive anticancer drugs associated with clinically significant incidence of febrile neutropenia.

Rolvedon is a long-acting granulocyte colony-stimulating factor (G-CSF) comprised of 2 protein components, an analogue of G-CSF and an Fc antibody fragment. The approval was based on data from two phase 3 trials, ADVANCE ( Identifier: NCT02643420) and RECOVER ( Identifier: NCT02953340), which evaluated the safety and efficacy of eflapegrastim in 643 early-stage breast cancer patients who had neutropenia due to myelosuppressive cytotoxic chemotherapy.

Findings from both trials showed that the primary endpoint of noninferiority in the duration of severe neutropenia between eflapegrastim and pegfilgrastim was met. Additionally, no statistically significant differences in adverse events were observed between eflapegrastim and pegfilgrastim.
