Among the six HCV genotypes, genotype 1 was significantly more aggressive when utilizing the combination of pegylated interferon and ribavirin, as genotype 1-infected patients had the lowest likelihood of achieving cure (40%–50%) and required twice as long duration of treatment, as compared to genotypes 2 and 3. Recently, however, significant advances have been made with the advent of all-oral direct-acting antiviral agents, which have significantly improved the safety, efficacy, and tolerability of the treatment of HCV genotype 1. Among the available treatments for HCV genotype 1, the combination therapy of ledipasvir/sofosbuvir provides several advantages compared to other regimens, including use of a single-pill regimen, possibility to shorten the duration of treatment to 8 weeks, efficacy in patients exposed to protease inhibitors, safety in decompensated cirrhosis, and potential to avoid ribavirin. In this review, we discuss the pharmacotherapy of the combination of ledipasvir/sofosbuvir therapy and summarize the results of the Phase III clinical trials for this treatment in HCV genotype 1 patients. We will also discuss the data for special populations, including decompensated cirrhosis, human immunodeficiency virus (HIV) coinfected patients, African-Americans, the elderly, and those who failed sofosbuvir-containing regimens.Keywords: pegylated interferon, ribavirin, cirrhosis, liver transplantation, direct-acting antiviral
