ABSTRACT
BACKGROUND: The combination of ledipasvir plus sofosbuvir was recently approved for treatment of adolescent (12-17 years) HCV genotype 1, 4, 5 & 6 patients. However, few clinical trials have been performed in genotype 1 patients. AIM: To investigate the effectiveness and safety of ledipasvir plus sofosbuvir in chronic HCV adolescent patients with genotype 4 in the real world. METHODS: This prospective multicentre (six centres) open-label study included 144 adolescent chronic HCV patients with genotype 4 (mean age 14 ± 2, 69% males). All patients received a combination tablet containing 400 mg sofosbuvir and 90 mg ledipasvir once daily for 12 weeks. Laboratory and virological markers were evaluated at baseline, week 4, week 8 and week 12 (EOT), and 12 weeks after end of treatment (SVR12). RESULTS: SVR12 was observed in 142/144 patients (99%). The relapsers occurred in previous naïve patients (n = 2/128, 2%), while the experienced patients showed 100% SVR12. SVR12 was 98% in F0/F1 patients in comparison to 100% in F2 patients (P = 0.552). No serious side effects were observed, nor was treatment discontinuation or death. Headache was the most common side effect in all patients (20%). In experienced patients, pruritus (31%, P = 0.007), diarrhoea (44%, P < 0.001) and skin rash (19%, P = 0.002) were higher than in naïve patients. CONCLUSIONS: A ledipasvir plus sofosbuvir regimen is well tolerated and effective, and can be used safely in treating adolescent patients with chronic hepatitis C genotype 4.
