PRIMARY outcome

Timeframe: End of 24-weeks follow-up (Week 72)

Population: Intent-to-treat (ITT) population included all participants who received at least one dose of study medication and had one subsequent post baseline assessment. Here, "number of participants analyzed" signified those participants who were evaluable for this outcome.

HBV-DNA was assessed in plasma samples using quantitative Roche polymerase chain reaction (PCR) or Taqman tests.

HBsAg seroconversion was defined as the absence of HBsAg (a negative result for HBsAg) and the presence of anti-HBs (a positive result for anti-HBs). Both HBeAg positive and negative participants were HBsAg positive at baseline and absence of HBsAg (seroconversion) was analyzed.

ALT is an enzyme found mainly in liver and is measured to check if the liver is damaged or diseased. In case of liver damage or disease, the liver releases ALT into the blood stream and the ALT level increases. Normal ALT level = less than upper limit of normal (40 units per liter).
