Trial information
A Study of PEGASYS (Peginterferon alfa-2a (40KD)) Plus Entecavir in Treatment-Naive Patients With HBeAg-Positive Chronic Hepatitis B.
Status: Recruiting
Protocol number: ML20742
Sponsor: Hoffmann-La Roche
Company division: Pharmaceutical
Official Scientific Title: A randomized, open label study of the effect of Peginterferon alfa-2a (40KD) (PEGASYS®) plus entecavir (Baraclude®) combination therapy on quantitative changes in HBeAg in treatment-naive patients with HBeAg positive chronic hepatitis B
Brief summary: This 3 arm study will assess the efficacy and safety of PEGASYS + entecavir combination therapy in treatment-naive patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms s.c./week for 48 weeks, 2)PEGASYS 180 micrograms s.c./week for 48 weeks + entecavir 0.5mg p.o. once daily from week 13 to week 36 or 3) entecavir 0.5mg p.o. once daily for 24 weeks + PEGASYS 180 micrograms s.c./week from week 21 to 68. Treatment will be followed by 24 weeks treatment-free follow up. The anticipated time on study treatment is 3-12 months for groups 1 and 2, and 1-2 years for group 3, and the target sample size is 100-500 individuals. Target sample size is 210.
