Terms & Properties

Preferred Name: Peginterferon Alfa-2b

Definition: A covalent conjugate of recombinant interferon alpha, subtype 2b, and polyethylene glycol (PEG), used as an antiviral and antineoplastic agent. The biological activity of this agent is derived from its interferon alpha-2b protein moiety. Interferons alfa bind to specific cell-surface receptors, leading to the transcription and translation of genes whose protein products mediate antiviral, antiproliferative, anticancer, and immune-modulating effects. The PEG moiety lowers the clearance of interferon alpha-2b, thereby extending the duration of its therapeutic effects, but may also reduce the interferon-mediated stimulation of an immune response. (NCI04)

NCI-GLOSS Definition: A drug used to treat hepatitis C infections. It is also being studied in the treatment and prevention of cancer. It is a cytokine that is modified in the laboratory. It is a type of biological response modifier.
