Percentage of Participants With Loss of Hepatitis B Envelope Antigen at Week 48
Periodo de tiempo: At Week 48
|
Loss of Hepatitis B Envelope Antigen (HBeAg) is defined as the absence of HBeAg.
|
At Week 48
|
|
Percentage of Participants With Hepatitis B Virus - Deoxyribonucleic Acid <1000 Copies/ Millilitre at Week 48
Periodo de tiempo: At Week 48
|
Blood was collected for Hepatitis B Virus - Deoxyribonucleic Acid (HBV -DNA) and was analysed at the central laboratories using the Roche approved polymerase chain reaction (PCR) methodology at Week 48.
Percentage of participants with HBV-DNA < 1000 copies/mL was reported.
|
At Week 48
|
|
Percentage of Participants With Hepatitis B Surface Antigen Loss at Week 48
Periodo de tiempo: At Week 48
|
Loss of Hepatitis B Surface Antigen (HBsAg) was defined as change of detectable HBsAg from positive to negative.
|
At Week 48
|
|
Percentage of Participants With Hepatitis B Surface Antigen Seroconversion at Week 48
Periodo de tiempo: At Week 48
|
Hepatitis B Surface Antigen (HBsAg) seroconversion was defined as loss of HBsAg and presence of anti-HBs .(antibody to Hepatitis B surface antigen)
|
At Week 48
|
|
Percentage of Participants With Normalized Alanine Aminotransferase at Week 48
Periodo de tiempo: At Week 48
|
Normalized Alanine Aminotransferase (ALT) is defined as having a baseline ALT value > upper limit of normal (ULN), and a decrease in ALT value to ≤ ULN at the given time point.
|
At Week 48
|
|
Quantitative Change in Mean Hepatitis B Envelope Antigen Over Time
Periodo de tiempo: Up to Week 48
|
Quantitative hepatitis B envelope antigen (HBeAg) results were analyzed in central lab.
Values that were less than lower limit of quantification (LLOQ) had been replaced by LLOQ when analyzed, e.g.
<1000 was replaced by 1000 and <0.2 was replaced by 0.2.
Quantitative HBeAg value unit was calculated using 'Paul Ehrlich Institute units per millilitre' (PEIU/ml).
Change in HBeAg was analysed at Weeks 0, 8, 12, 24, 36, and 48.

|
Quantitative Change in Mean Hepatitis B Surface Antigen Change Over Time
Periodo de tiempo: Up to Week 48
|
Quantitative Hepatitis B Surface Antigen (HBsAg) results were analyzed in central lab.
Values that were less than LLOQ had been replaced by LLOQ when analyzed, e.g.
<1000 was replaced by 1000 and <0.2 was replaced by 0.2.
Quantitative HBsAg calculated using 'International Units Per Millilitre' (IU/mL).
Change in HBsAg was analysed at Weeks 0, 8, 12, 24, 36, and 48.
|
Up to Week 48

|
Number of Participants With Incidence of Adverse Events and Serious Adverse Events
Periodo de tiempo: Up to Week 48
|
An adverse event (AE) was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started.
An adverse event was therefore any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug.
A Serious Adverse Events (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.
|
Up to Week 48
|
|
Number of Participants With Laboratory Abnormalities Which Were Captured as an Adverse Event
Periodo de tiempo: Up to Week 48
|
Participants with clinically significant laboratory abnormalities which were captured as an AE (at the >=5% threshold) were presented.
|
Up to Week 48
