Abstract
Chronic Hepatitis C (HCV) infection occurs in more than 130 to 150 million individuals world wide. Twenty percent of patients chronically infected with HCV progress to cirrhosis. Other than cirrhosis, Chronic HCV infection is strongly associated with liver cancer and end-stage liver disease requiring transplantation. However, as with the approval of the fisrt generation protease inhibitors telaprevir and boceprevir, we see significant progress in the treatment of chronic hepatitis c infection. However this has benefited many but not all patients with HCV infection as protease inhibitors have never been approved for genotype 2 and 3. No direct acting antiviral agents have ever been approved until recently. Very recently sofosbuvir, a direct acting antiviral agent which is a nucleotide polymerase inhibitor, has been approved for genotypes 2, 3, (and genotypes 1 and 4), where as multiple direct acting agents are approved and used for genotype 1 which includes but is not limited to Simeprevir. Now patients with genotype 3 have emerged among the hardest to treat. The reason behind this treatment failure of genotype 3 infections is that genotype 3 still remains a challenge to the efficacy of even newer regimen Also genotype 3 is associated with a more rapid progression of the disease. In addition, genotype 4 is increasing in Europe. Thus we want to emphasize the ongoing need for new, simpler therapeutics using direct –acting antivirals that target various stages of the HCV lifecycle to eradicate HCV without concomitant INF.
