Glecaprevir/pibrentasvir therapy is effective and well tolerated in patients aged > 75 years with hepatitis C virus (HCV) infection, according to a retrospective study published in Geriatrics & Gerontology International.1

Because of an increasingly longer lifespan, the number of older patients with HCV infection has also increased; however, these patients are less likely to receive antiviral treatments especially those containing interferon, due to comorbidities and poor tolerability.1 Studies have shown that direct-acting antivirals (DAAs) are effective and safe in older patients with HCV infection.2-4 Glecaprevir/pibrentasvir is a pangenotypic DAA combination therapy that has demonstrated high sustained virologic response rates with favorable safety in patients with chronic HCV infection infection.5-8

Few studies have evaluated this therapy in patients with HCV infection aged > 75 years, therefore researchers in Japan compared 43 HCV patients aged > 75 years with 88 HCV patients < 75 years, all of whom received treatment with glecaprevir/pibrentasvir.1

Among patients aged > 75 years, researchers found the presence of cirrhosis in 27.9%, a history of hepatocellular carcinoma in 23.3%, and comorbidities in 88.4%; compared with 12.5%, 2.3% and 69.5%, respectively. In the intention-to-treat population, 86.0% in the aged > 75 years group and 78.4% in < 75 years group demonstrated sustained virologic response at 12 weeks after treatment (P = .30); this demonstrated a nonsignificant difference in treatment effectiveness between the 2 group.

Overall, 27.5% of the study cohort experienced adverse events, the most frequent of which was pruritus; adverse events occurred significantly more commonly among women, in the presence of hemodialysis, and serum albumin at baseline < 4.0 g/dL.
