Synergistic Effect of Biejia-Ruangan on Fibrosis Regression in Patients With Chronic Hepatitis B Treated With Entecavir: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial

Background Long-term nucleos(t)ide analogue (NA) treatment can reverse liver fibrosis in chronic hepatitis B (CHB), but its effect on fibrosis regression remains limited. Biejia-Ruangan (BR) has been approved in China as an antifibrotic traditional Chinese medicine drug in patients with chronic liver diseases. A multicenter randomized controlled trial aims to evaluate the effect of BR on fibrosis regression in CHB patients treated with NAs. Methods CHB patients with histologically confirmed advanced fibrosis or cirrhosis were randomly assigned to receive entecavir (ETV) (0.5 mg per day) plus BR (2 g 3 times a day) or placebo for 72 weeks. Liver fibrosis regression was defined as a reduction of >= 1 point by the Ishak fibrosis stage (IFS). Results Overall, 500 patients were enrolled in each group as the intention-to-treat population. The rate of fibrosis regression after 72 weeks of treatment was significantly higher in the ETV + BR group (40% vs 31.8%; P = .0069). Among 388 patients with cirrhosis (ie, IFS >= 5) at baseline, the rate of cirrhosis reversal (ie, IFS <= 4) was significantly higher in the ETV + BR group (41.5% vs 30.7%; P = .0103). Conclusions Addition of BR to the current standard treatment with NAs in CHB patients with advanced fibrosis or cirrhosis can improve liver fibrosis regression. In this multicenter randomized controlled trial of 1000 patients with chronic hepatitis B and advanced fibrosis or cirrhosis, Biejia-Ruangan as an add-on therapy to entecavir significantly increased rates of fibrosis regression and cirrhosis reversal.

Automated summary

Addition of Biejia-Ruangan (BR) to the current standard treatment with entecavir (ETV) can significantly increase rates of fibrosis regression in patients with chronic hepatitis B and advanced fibrosis or cirrhosis.
