Mechanism of action

IVIG-PEG combines standard intravenous immunoglobulin (IVIG) with polyethylene glycol (PEG) conjugation to prolong circulating half-life and reduce dosing frequency. The PEG modification allows for less frequent administration while maintaining therapeutic antibody levels. This approach is intended to improve patient convenience and compliance in immunodeficiency and autoimmune conditions.
