Peginterferon alfa-2a 40KD and Ribavirin
Peginterferon alfa-2a 40KD and Ribavirin is a Interferon alpha with nucleoside analog Small molecule drug developed by NORDynamIC Study Group. It is currently FDA-approved for Chronic hepatitis C virus infection (genotype-dependent, now largely superseded by direct-acting antivirals).
Peginterferon alfa-2a activates interferon-alpha receptors to enhance antiviral immunity, while ribavirin inhibits viral RNA synthesis, together suppressing hepatitis C virus replication.

Mechanism of action
Peginterferon alfa-2a is a long-acting interferon that binds to type I interferon receptors, triggering JAK-STAT signaling to induce antiviral and immunomodulatory responses. Ribavirin is a nucleoside analog that inhibits viral RNA-dependent RNA polymerase and may enhance T-cell responses. Together, this combination was the standard-of-care treatment for chronic hepatitis C before direct-acting antivirals became available.
