BACKGROUND AND AIM: In this study, we investigated the real-world data of the first approved interferon-free regimen in Japan: daclatasvir and asunaprevir in chronic hepatitis C patients with severe fibrosis.
METHODS: Among 924 patients registered in our multicenter study, 535 patients were defined as having severe fibrosis with Fib-4 index ≧ 3.25 and were included in this study. We investigated antiviral effect and factors associated with sustained viral response 12 (SVR12), and the additional effects on serum α-fetoprotein and albumin levels by eradicating virus in patients who attained SVR were investigated. In statistical analysis, P < 0.05 was considered as significant levels.
RESULTS: Antiviral effect was lower in patients with severe fibrosis at 8 and 12 weeks after start of the treatment (96.3%, 97.1% with severe fibrosis vs 99.5%, 99.2% without severe fibrosis, P = 0.002 and P = 0.036, respectively), and more early relapse (SVR4; 90.4% with severe fibrosis vs 95.4% without fibrosis, P = 0.008) was seen in patients with severe fibrosis; however, there were no differences in SVR12 and SVR24. In the safety profiles, discontinuation rate due to liver injury (2.8% with severe fibrosis vs 3.3% without severe fibrosis) or other causes of discontinuation was not different between two groups. Serum α-fetoprotein significantly decreased, and serum albumin levels significantly increased as early as 4 weeks after the start of treatment.
CONCLUSION: Although the antiviral effect was slightly lower in patients with severe fibrosis compared with those without, treatment with daclatasvir and asunaprevir is basically an effective and well-tolerable treatment in these populations.
