1.Primary Outcome
Title Change in Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) Level From Baseline to Week 12.
Hide Description Baseline HBV DNA is defined as the last pre-dose assessment of HBV DNA. Serum HBV DNA determinations were performed at a central laboratory through use of the COBAS TaqMan™ HBV DNA assay (Roche Molecular Systems, Pleasanton, CA, USA) which utilized the Real-time polymerase chain reaction (PCR) method and automated extraction by Cobas Ampliprep (threshold for detection 12 IU/mL). The Screening serum HBV DNA values must be ≥ 7 log10 copies/mL by COBAS TaqMan™ HBV DNA assay.

Title Percentage of Patients Who Achieve Hepatitis B "e" Antigen (HBeAg) Loss and HBeAg Seroconversion at Week 12
Hide Description HBeAg loss is defined as the loss of detectable serum HBeAg in a patient who was HBeAg positive at baseline. HBeAg seroconversion is defined as HBeAg loss with detectable Hepatitis B 'e' antibody (HBeAb). HBeAg stands for hepatitis B "e" antigen. This antigen is a protein from the hepatitis B virus that circulates in infected blood when the virus is actively replicating. The presence of HBeAg suggests that the person is infectious and is able to spread the virus to other people.

Title Characterization of Very Early Viral Kinetics Through Rate of Infected Cell Loss
Hide Description

The underlying bi-phasic model of viral kinetics can be described as follows:

V(t) (1 )pI(t) cV(t)I(t) (1 ) (T I(t))V(t) I(t)where V denotes serum viral load, I productively infected cells, ε the efficiency factor of blocking virus production, p the viral production rate, c the viral clearance rate, η the efficiency factor of blocking de novo infection, β the de novo infection rate, Tg comprise all infected and uninfected target cells, and δ the rate of infected cell loss

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The terms and conditions of Novartis' agreements with its investigators may vary. However, Novartis does not prohibit any investigator from publishing. Any publications from a single-site are postponed until the publication of the pooled data (i.e., data from all sites) in the clinical trial.
