Mechanism of action

Double filtration plasmapheresis (DFPP) is an extracorporeal blood purification technique that selectively removes large molecular weight substances including immune complexes and immunoglobulins. When combined with pegylated interferon-alpha (Peg-IFN), which activates innate immunity and has direct antiviral effects, and ribavirin (RBV), a nucleoside analog that inhibits viral RNA synthesis, this triple modality targets hepatitis C virus through multiple mechanisms: reducing viral load, clearing immune-mediated damage, and enhancing interferon-based antiviral immunity.
