Overview

Pegylated interferon alfa-2a (pegylated with a branched 40 kDa PEG chain; commercial name Pegasys) is an antiviral drug discovered at the pharmaceutical company F. Hoffmann-La Roche; it has a dual mode of action - both antiviral and on the immune system. The addition of polyethylene glycol to the interferon, through a process known as pegylation, enhances the half-life of the interferon when compared to its native form.

Mechanism of Action

The mechanism by which Interferon alfa-2a, recombinant, or any other interferon, exerts antitumor or antiviral activity is not clearly understood. However, it is believed that direct antiproliferative action against tumor cells, inhibition of virus replication and modulation of the host immune response play important roles in antitumor and antiviral activity.
