Mechanism of action

Filgrastim and pegylated filgrastim work by binding to and activating the granulocyte colony-stimulating factor receptor (G-CSFR), which triggers a signaling cascade that leads to the release of neutrophils from the bone marrow into the bloodstream. Pegylated filgrastim has a longer half-life than filgrastim due to the addition of polyethylene glycol (PEG) chains, allowing for less frequent dosing.
