What are telaprevir and boceprevir?
Both boceprevir and telaprevir are NS3/4A protease inhibitors. The NS3 protease is an enzyme that catalyzes the post-transcriptional processing of proteins important for viral replication. NS4A is a cofactor that works with NS3 to expedite this process.

What is NS5A inhibitor?
What are NS5A inhibitors? Non-structural protein 5A (NS5A) inhibitors are a direct-acting antiviral agent used to treat hepatitis C virus (HCV). The NS5A protein has a substantial role in viral replication, packaging, assembly and complex interactions with cellular functions.
Can boceprevir cure HCV?
It was approved in Europe in July 2011 for treatment of adults with genotype 1 chronic hepatitis C in combination with pegylated interferon and ribavirin. Overall, boceprevir triple therapy cures about two-thirds of people who take it, but it works better for some groups than others.
