[Treatment of chronic hepatitis C by bicyclum, a randomized double-blind placebo controlled trial].
OBJECTIVE
To evaluate the efficacy and safety of bicyclum, a China made new hepatocyte protecting agent, in the treatment of chronic hepatitis C (CHC).


METHODS
Thirty-nine CHC patients matched demographically and clinically were randomized into two groups: bicyclum group (group A, n = 20) and placebo/bicyclum crossovergroup (group B, n = 19). Bicyclum 75mg/d or placebo was administered to these two groups respectively for 3 months. Then the patients in group A received bicyclum for further 3 months and were observed for 3 months after the treatment discontinued; and the patients in group B received bicyclum 75mg/d for six months and were observed for 3 months after the treatment discontinued. Investigation items included clinical manifestations,liver function, serum HCV RNA and anti-HCV.


RESULTS
In group A, the serum ALT was 120 +/- 43 U/L before treatment and was 57 +/- 32 U/L after treatment ( P < 0.01) In group B the baseline serum ALT was 126 U/L +/- 48 U/L. After the placebo administration the serum ALT was 127 U/L +/- 97 U/L (P > 0.05) and the clinical feature showed no improvement. After bicyclum treatment for 6 months, the serum ALT in group B was 68 +/- 45 U/L, significantly lower than that before bicyclum treatment ( P < 0.01) and clinical symptoms improved. The overall ALT normalization response rate were 64.1% and 48.7% at the end of bicyclum treatment and 3 months after the treatment discontinued respectively for the total 39 patients. The serum HCV-RNA became negative in 5 and 2 patients at end of treatment and 3 months after the treatment discontinued. Adverse drug reactions were mild and uncommon. Mild dizziness occurred in 1 patient in each group.


CONCLUSIONS
Bicyclum is effective in improving ALT and clinical manifestations of CHC patients. It is safe and well tolerated and shows few adverse reactions.
