Brief summary

The purpose of the study is to compare safety and efficacy of a single dose of empegfilgrastimt a dose of 3 or 6 mg versus daily administration of filgrastim at a dose of 5 μg/kg/day.

Detailed description

BCD-017-2 is an open-label randomized phase II clinical study to compare the incidence of CTCAE grade 3/4 neutropenia after a single administration of recombinant human pegylated filgrastim empegfilgrastim (Extimia®) at a dose of 3 or 6 mg versus daily administration of filgrastim at a dose of 5 μg/kg/day for neutropenia prophylaxis in breast cancer patients receiving myelosuppressive chemotherapy.

Interventions

BIOLOGICALempegfilrastim

Empegfilgrastim is supplied as solution for injection 3 mg/ml. Empegfilgrastim is to be administered 24 h after the chemotherapy at dose of 3 or 6 mg.

BIOLOGICALfilgrastim

Filgrastim should be administered no earlier than 24 hours after the administration of cytotoxic chemotherapy. Filgrastim should be administered daily for up to 2 weeks until the ANC has reached 10 000/mm3 following the expected chemotherapy-induced neutrophil nadir.
