UMIN ID: UMIN000000595

Registered date:01/08/2007

Basic Information

• Health condition(s) or Problem(s) studied: chronic hepatitis B
• Date of first enrollment: 2006/11/01
• Target sample size: 170
• Countries of recruitment: Japan
• Study type: Interventional

Intervention(s)

Interferon-entecavir sequential therapy arm:A single dose of 6 mega units of recombinant interferon-alpha2b (brand name: intron A) or natural IFN-alpha (brand name: Sumiferon) is administered subcutaneously 3 times per week for 24 weeks. Administration of entecavir (brand name: Baraclude), given orally every day in a daily dose of 0.5mg before retiring at night, is started at the first day of the 21st week and continued for 13 months. Afterwards, the course is observed without anti-viral medications until the end of the 24th month.
Interferon monotherapy arm: A single dose of 6 mega units of recombinant interferon-alpha2b (brand name: intron A) or natural IFN-alpha (brand name: Sumiferon) is administered subcutaneously 3 times per week for 24 weeks. Afterwards, the course is observed until the end of the 56th week without anti-viral medications. If HBeAg and HBV DNA is positive and ALT is abnormal at the 52th week, administration of entecavir (brand name: Baraclude), given orally every day in a daily dose of 0.5mg before retiring at night, is started at the 56th week. If not, the course observation is continued.

Outcome(s)

• Primary Outcome: (1)Change of HBV DNA level from baseline (2)Fall of HBV DNA to less than 2.6 log copies/ml (3)HBeAg clearance (4)HBeAg seroconversion (5)Emergence of entecavir-resistance
• Secondary Outcome: (1)ALT (2)Albumin (3)Prothrombin time(%) (4)Total Bilirubin (5)Platelet count (6)Ascites (7)Hepatic encephalopathy (8)Child-Pugh score (9)Development of hepatocellular carcinoma (10)HBV precore mutation (11)HBV core promoter mutation
