Ethnopharmacological relevance: Antiviral therapy can alleviate liver fibrosis in chronic hepatitis B, but it has a limited effect on advanced liver fibrosis/cirrhosis. Traditional Chinese medicine (TCM), particularly FuZheng HuaYu (FZHY) tablet, appears to have an antifibrotic effect, but its improving resolution of hepatitis b virus (HBV) -associated advanced fibrosis and experienced anti-viral treatment has not been investigated.Aim of the study: To observe the safety and efficacy of adjunctive FZHY on the HBV-associated cirrhosis patients who received 2 years of entecavir but still with advanced fibrosis.Methods: An open-label, multicentre, single arm trial. 251 patients were included and treated with TCM consisted of FZHY tablets 1.6 g and granules, three times a day in addition to entecavir 0.5 mg daily for an additional 48 weeks. Primary outcome was regression of fibrosis (the proportion of patients with a 1-point decrease in the Ishak liver fibrosis score from baseline to week 48).Results: Fibrosis regression occurred in 94 of 184 patients with paired liver biopsy (51.09%, 95% CI: 43.9-58.0). In 132 compensated cirrhosis patients (Ishak score >= 5), 56.06% (74/132, 95% CI: 47.5-64.2) showed fibrosis regression and reached the goal of 54% (15% more than entecavir mono-therapy). 10 patients occurred adverse reaction, most of them were mild, and all recovered or achieved remission.Conclusions: The combination therapy of FZHY, TCM granules and ETV could regress the liver fibrosis in the patients with HBV cirrhosis, who experienced 2 years of ETV treatment, and it is safe and well tolerated.
