The treatment landscape for hepatitis C virus (HCV) infection has transformed over the past few decades, evolving from the limited efficacy of interferon (IFN) monotherapy to the highly successful pan-genotypic direct-acting antivirals (DAAs) used today. Initially, alpha-interferon monotherapy, introduced in the 1990s, was the standard treatment, yet it provided low sustained virological response (SVR) rates and caused significant adverse effects, limiting its utility. The development of pegylated interferon (peg-IFN) improved the pharmacokinetic profile of IFN, allowing for less frequent dosing and modestly improved response rates. When combined with ribavirin, peg-IFN achieved higher SVR rates, especially in non-genotype 1 HCV infections, but the combination also brought additional side effects, such as anemia and depression. The advent of the first-generation DAAs, such as telaprevir and boceprevir, marked a significant milestone. Combined with peg-IFN and ribavirin, these protease inhibitors boosted response rates in patients with genotype 1 HCV. However, high rates of adverse effects and drug resistance remained challenges. Second-generation DAAs, like sofosbuvir and ledipasvir, introduced IFN-free regimens with improved safety profiles and efficacy. The most recent advances are pan-genotypic DAAs, including glecaprevir-pibrentasvir and sofosbuvir-velpatasvir, which offer high SVR rates across all genotypes, shorter treatment durations, and fewer side effects. Current pan-genotypic regimens represent a cornerstone in HCV therapy, providing an accessible and effective solution globally.
