Background: To evaluate the effectiveness and safety of ledipasvir/sofosbuvir (LDV/SOF)±ribavirin (RBV) regimen in a real-world setting.
Methods: Patients received a fixed-dose combination tablet containing LDV and SOF with or without RBV, for 8, 12 or 24 weeks. Patients were assessed at baseline, end of treatment, and 12 weeks after the end of treatment. The primary effectiveness endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12).
Results: Of the 86 patients, aged 20-80 years, 82.6% were HCV genotype 1b-infected and 50.0% were cirrhotic. More than half (52.3%) had previously followed pegylated interferon-containing (PEG-IFN) treatment regimens, and 38.5% were null-responders. SVR12 was achieved by 94.2% of patients. All non-responders were cirrhotic: two demonstrated virologic breakthrough and the remaining three relapsed. All patients treated with an 8-week regimen achieved SVR12 despite having high viral load at baseline (HCV RNA of >1 million IU/mL in 8/10 patients, including one with a viral load of >6 million IU/mL). Adverse events were generally mild and transient. Most frequently, fatigue (22.1%), headache (15.1%), and arthralgia (7.0%) were observed. Laboratory abnormalities included anemia and hyperbilirubinemia.
Conclusions: Treatment with LDV/SOF±RBV is an effective and safe option for patients with HCV, including those with advanced liver disease or a history of non-response to PEG-IFN-based therapy.
