Primary Outcome Measures
NameTimeMethod
<p>The primary efficacy variable of this study is the proportion of patients who<br /><br>will achieve HBV DNA non-detectability by PCR at Week 52.<br /><br><br /><br>The proportion of patients (response rate) who will achieve HBV DNA<br /><br>non-detectability at Week 52 and ALT normalization after 52 weeks* treatment<br /><br>will be tested using the CMH test, stratified by country and/or baseline HBV<br /><br>DNA level. The ratio of the response rates and the difference of the response<br /><br>rates for combination therapy vs. peginterferon alfa-2a monotherapy will be<br /><br>provided along with a 95% confidence interval.</p><br>
Secondary Outcome Measures

<p>The proportion of patients (response rate) who will achieve HBV DNA<br /><br>non-detectability at Week 52 and ALT normalization after 52 weeks* treatment<br /><br>will be tested using the CMH test.</p><br>
