Early Response to Interferon Combined Short-Term Nucleoside Analogue Therapy in HBeAg(+) Chronic Hepatitis B

March 11, 2009 updated by: Sun Yat-sen University
For HBeAg(+) patients, interferon is used for 12 weeks. On 12th week of treatment, If HBV DNA is undetectable (<1000 copies/ml), interferon is continued alone for one year. If HBV DNA is still positive, nucleoside analogue is added for 3 months. After nucleoside analogue is added for 3 months, HBV DNA is tested again. If negative, stop nucleoside analogue and use interferon alone for another 6 months or longer. If HBV DNA is still positive, change to another nucleoside analogue or add another nucleoside analogue.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 1
At the twelfth week of interferon α treatment, HBV DNA is detectable(>1000 copies/ml), or HBeAg is still positive. And nucleoside analogue is added for 12 weeks.
Drug: interferon α plus nucleoside analogue
Standard dose of interferon is used for 12 weeks. On 12th week of treatment, HBV DNA is still detectable (>1000 copies/ml), or HBeAg is still positive. And lamivudine is added for 3 months. After nucleoside analogue is added for 3 months, HBV DNA is tested again. If negative, stop nucleoside analogue and use interferon alone for another 6 months or longer. If HBV DNA is still positive, change to another nucleoside analogue or add another nucleoside analogue.
Active Comparator: 2
At the twelfth week of interferon α treatment, HBV DNA is detectable (>1000 copies/ml), or HBeAg is still positive. But no nucleoside analogue is added.
Drug: interferon α
Standard dose of interferon is used for 12 weeks.On 12th week of treatment, HBV DNA is still detectable (>1000 copies/ml), or HBeAg is still positive. But no nucleoside analogue is added.
Drug: interferon α
Standard dose of interferon is used for 12 weeks.On 12th week of treatment, HBV DNA is undetectable, or HBeAg is negative. And interferon is continued alone for another 9 months.
Active Comparator: 3
At the twelfth week of interferon α treatment, HBV DNA is undetectable (<1000 copies/ml), or HBeAg is negative. And interferon is continued for another 9 months.
Drug: interferon α
Standard dose of interferon is used for 12 weeks.On 12th week of treatment, HBV DNA is still detectable (>1000 copies/ml), or HBeAg is still positive. But no nucleoside analogue is added.
Drug: interferon α
Standard dose of interferon is used for 12 weeks.On 12th week of treatment, HBV DNA is undetectable, or HBeAg is negative. And interferon is continued alone for another 9 months.
