Effectiveness and safety of ledipasvir/sofosbuvir for genotype 2 chronic hepatitis C infection: Real-world experience from Taiwan.

Background/purpose: Genotype 2 (GT2) hepatitis C virus infection is the second common genotype in Taiwan. Real-world experience of ledipasvir/sofosbuvir (LDV/SOF) for GT2 infection is limited. The aim of this study is to evaluate the effectiveness and safety of LDV/SOF in patients with GT2 chronic hepatitis C (CHC) infection.
Methods: CHC patients with GT2 infection receiving 12 weeks LDV/SOF from three hospitals were enrolled. HCV RNA was checked at baseline, end-of-treatment and 12 weeks after completing treatment. Demographic data, adverse events, renal function and metabolic profiles were recorded.
Results: Among 392 enrolled patients, 33 patients (8.4%) were cirrhotic. Sustained virological response (SVR) rate was 96.7% (379/392) by intention-to-treat analysis and 97.2% (379/390) by per-protocol analysis. The SVR rate was lower in cirrhotic patients than in non-cirrhotic patients (90.6% vs 97.8%, p = 0.053). Two cirrhotic patients who took LDV/SOF plus ribavirin both achieved SVR. Neither drug-related severe adverse events nor discontinuation due to drug-related adverse event were reported. The estimated glomerular filtration rate (eGFR) remained stable in patients with chronic kidney disease 3a/3b.
Conclusion: Twelve weeks of LDV/SOF treatment provided an excellent and safe regimen for GT2 CHC infection, particularly in non-cirrhotic patients.
