Oxymatrine therapy for chronic hepatitis B:A randomized doubleblind and placebo-controlled multi-center trial

AIM: To evaluate the efficacy and safety of capsule oxymatrine in the treatment of chronic hepatitis B.METHODS: A randomised double-blind and placebocontrolled multicenter trial was conducted. Injection of oxymatrine was used as positive-control drug. A total of 216 patients with chronic hepatitis B entered the study for 24 weeks, of them 108 received capsule oxymatrine, 36 received injection of oxymatrine, and 72 received placebo.After and before the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reaction were observed.RESULTS: Among the 216 patients, six were dropped off,and 11 inconsistent with the standard were excluded.Therefore, the efficacy and safety of oxymatrine in patients were analysed. In the capsule treated patients, 76.47 % became normal in ALT level, 38.61% and 31.91% became negative both in HBV DNA and in HBeAg. In the injection treated patients, 83.33 % became normal in ALT level,43.33 % and 39.29 % became negative both in HBV DNA and in HBeAg. In the placebo treated patients, 40.00 % became normal in ALT level, 7.46 % and 6.45 % became negative both in HBV DNA and in HBeAg. The rates of complete response and partial response were 24.51% and 57.84 % in the capsule treated patients, and 33.33 % and 50.00 % in the injection treated patients, and 2.99 % and 41.79 % in the placebo treated patients, respectively.There was no significance between the two groups of patients, but both were significantly higher than the placebo. The adverse drug reaction rates of the capsule,injection and placebo were 7.77 %, 6.67 % and 8.82 %,respectively. There was no statistically significant difference among them.CONCLUSION: Oxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

Capsule oxymatrine in treatment of hepatic fibrosis due to chronic viral hepatitis:A randomized,double blind,placebo-controlled,multicenter clinical study

AIM: To evaluate the efficacy and safety of oxymatrine capsule in treatment of hepatic fibrosis in patients with chronic viral hepatitis. METHODS: It was a randomized, double blind, placebocontrolled, multicenter clinical study. One hundred and fortyfour patients were divided into oxymatrine capsule group (group A) and placebo group (group B). The course was 52wk. Patients were visited once every 12wk and the last visit was at 12wk after cessation of the treatment. All patients had liver biopsy before treatment, part of them had a second biopsy at the end of therapy. Clinical symptoms, liver function test, serum markers of hepatic fibrosis were tested. Ultrasound evaluation was performed before, during and at the end of therapy. RESULTS: One hundred and forty-four patients enrolled in the study. Of them 132 patients completed the study according to the protocol, 49 patients had liver biopsy twice (25 patients in group A and 24 in group 13). At the end of therapy, significant improvements in hepatic fibrosis and inflammatory activity based on Semi-quantitative scoring system (SSS) were achieved in group A. The total effective rate of the treatment was 48.00%, much higher than that of 4.17% in group B (P<0.05). Significant improvement in serum markers of hepatic fibrosis such as hyaluronic acid (HA) and type Ⅲ procollagenic peptide (PⅢ P) in group A was seen (P<0.05). The total effective rate of serum markers at the end of therapy in group A was 68.19%, much higher than that of 34.85% in group B (P<0.05). The total effective rate of noninvasive markers at the end of therapy in group A was 66.67%, much higher than that of 30.30% in group B (P<0.05). The rate of adverse events was similar in two groups. CONCLUSION: Oxymatrine capsule is effective and safe in treatment of hepatic fibrosis due to chronic viral hepatitis.
