Shortened 8-Week Course of Sofosbuvir/Ledipasvir Therapy in Adolescents with Chronic Hepatitis C Infection

: Treatment-naive, noncirrhotic adults with chronic hepatitis C virus genotype 1 infection and with viremia levels <6 million IU/mL could be effectively treated with sofosbuvir/ledipasvir for 8 weeks. The aim of this pilot, prospective, open-label, multicenter study was to evaluate the efficacy and safety of this shortened treatment course in adolescents (≥12 years). The efficacy endpoint was sustained virological response 12 weeks after the end of treatment. Safety was assessed by adverse events and clinical/laboratory data. Fourteen consecutive adolescents (median age 16.5 years, Q1 14.1-Q3 17.4; female 57.1%), vertically infected, were enrolled and treated (June 2018-January 2019). Overall, the end of treatment response and sustained virological response 12 weeks after the end of treatment were 100%. No grade 3 to 4 adverse event or a serious adverse event was observed. Further studies are needed to confirm the optimal efficacy of the shortened 8-week treatment with sofosbuvir/ledipasvir for treatment-naive, noncirrhotic adolescents with chronic hepatitis C virus genotype 1 infection and pretreatment viremia level < 6 million IU/mL.
