Rebetron, a combination of injected recombinant interferon alfa-2b with oral ribavirin has been approved by the FDA for treatment of chronic hepatitis C virus infection.

Telaprevir (Incivek – Vertex) and boceprevir (Victrelis – Merck) have been approved by the FDA for oral use in combination with peginterferon and ribavirin for treatment of chronic hepatitis C virus (HCV) genotype 1 infection in adults with compensated liver disease. Both telaprevir and boceprevir were developed specifically to inhibit the NS3/4A proteases that cleave HCV encoded polyproteins of the genotype 1 virus.

The FDA has approved the nucleotide polymerase inhibitor sofosbuvir (Sovaldi – Gilead) for use in combination with other antiviral drugs for treatment of chronic hepatitis C virus (HCV) infection.

The FDA has approved Zepatier (Merck), a fixed-dose combination of two direct-acting antiviral agents — elbasvir, an NS5A inhibitor, and grazoprevir, an NS3/4A protease inhibitor — for oral treatment of chronic hepatitis C virus (HCV) genotype 1 or 4 infection.

Recombinant interferon alfa-2b conjugated to polyethylene glycol (PEG-Intron), the first "pegylated"alpha interferon, has been approved by the FDA for once-a-week monotherapy of chronic hepatitis C virus (HCV) infection in patients not previously treated with alpha interferon.

The FDA has approved Technivie (Abbvie), a fixed-dose combination of the direct-acting antiviral agents ombitasvir and paritaprevir and the pharmacokinetic enhancer ritonavir, for oral treatment of chronic hepatitis C virus (HCV) genotype 4 infection in patients without cirrhosis. It is indicated for use in combination with ribavirin. Ombitasvir/paritaprevir/ritonavir copackaged with dasabuvir, an HCV RNA polymerase inhibitor that has little activity against HCV genotype 4, is approved as Viekira Pak for treatment of HCV genotype 1 infection.1HCV genotype 4 is uncommon in the US and Canada. It...

The FDA has approved Epclusa (Gilead), a fixed-dose combination of sofosbuvir (Sovaldi) and velpatasvir, a new direct-acting antiviral agent, for oral treatment of chronic hepatitis C virus (HCV) infection. Epclusa is the first oral combination to be approved for treatment of all six major HCV genotypes.

The FDA has approved Viekira Pak (Abbvie), a fixed-dose combination of two new direct-acting antiviral agents (ombitasvir, paritaprevir) with the pharmacologic enhancer ritonavir in one tablet, co-packaged with a third new direct-acting antiviral agent (dasabuvir) in a second tablet, for oral treatment of chronic hepatitis C virus (HCV) genotype 1 infection. Genotype 1 is responsible for 70-80% of HCV infections in the US.

The FDA has recently approved 2 new drugs for treatment of chronic hepatitis C virus (HCV) infection. Simeprevir (Olysio – Janssen) is the third oral protease inhibitor to be approved for use in combination with peginterferon and ribavirin for treatment of chronic HCV genotype 1 infection in adults with compensated liver disease. Telaprevir (Incivek) and boceprevir (Victrelis) were approved in 2011 for the same indication. Sofosbuvir (Sovaldi – Gilead), a nucleotide analog polymerase inhibitor that has been approved for use with and without interferon for treatment of multiple HCV...

The FDA has approved recombinant interferon alfa-2a conjugated to polyethylene glycol (Pegasys - Roche) alone or with oral ribavirin (Copegus - Roche) for treatment of adults with chronic hepatitis C virus (HCV) infections not previously treated with interferon alpha. The standard of care for treatment of most patients with hepatitis C has been once-weekly injections of peginterferon alfa-2b (PEG-Intron -Schering) plus oral ribavirin (Rebetol - Schering) (Medical Letter 2001; 43:54).
