Percentage of Participants With HBeAg Loss at Week 72 (for HBeAg-positive Participants)
HBeAg is a hepatitis B viral protein. HBeAg loss = HBeAg-negative at the specified analysis week.
Time frame: At week 72
Population: HBeAg positive participants at baseline who received at least 1 month of ETV therapy. LOCF approach was used for participants with no measurement in the specified visit window.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Entecavir (ETV) | Percentage of Participants With HBeAg Loss at Week 72 (for HBeAg-positive Participants) | 100 percentage of participants |
Percentage of Participants With HBeAg Seroconversion at Week 72 (for HBeAg-positive Participants)
HBeAg is a hepatitis B viral protein. HBeAg Seroconversion = HBeAg Loss and Presence of Hepatitis B e Antibody (HBeAb).
Time frame: At week 72
Population: HBeAg-positive participants at baseline who received at least 1 month of ETV therapy. LOCF approach was used for participants with no measurement in the specified visit window.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Entecavir (ETV) | Percentage of Participants With HBeAg Seroconversion at Week 72 (for HBeAg-positive Participants) | 0 percentage of participants |
Percentage of Participants With HBsAg Loss at Week 72
HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBsAg loss = HBsAg-negative at the specified analysis week.
Time frame: At week 72
Population: Evaluable participants: Treated participants who received at least 1 month of ETV therapy. LOCF approach was used for participants with no measurement in the specified visit window.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Entecavir (ETV) | Percentage of Participants With HBsAg Loss at Week 72 | 96.7 percentage of participants |
Percentage of Participants With HBsAg Recurrence At Week 72
HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBsAg recurrence is defined as having detectable HBsAg among participants who have already experienced loss of HBsAg on-treatment. HBsAg recurrence = HBsAg-positive at the specified analysis week.
Time frame: At week 72
Population: Evaluable participants: Treated participants who received at least 1 month of ETV therapy. LOCF approach was used for participants with no measurement in the specified visit window.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Entecavir (ETV) | Percentage of Participants With HBsAg Recurrence At Week 72 | 3.3 percentage of participants |
Percentage of Participants With HBsAg Seroconversion at Week 72
HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBs seroconversion is defined as HBsAg loss with positive HBsAb.
Time frame: At week 72
Population: Evaluable participants: Treated participants who received at least 1 month of ETV therapy. LOCF approach was used for participants with no measurement in the specified visit window.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Entecavir (ETV) | Percentage of Participants With HBsAg Seroconversion at Week 72 | 80.3 percentage of participants |
Percentage of Participants With HBV DNA < 50 IU/mL (Approximately 300 Copies/mL) by PCR at the End of Post-dosing Follow-up
HBV DNA assessments were to be performed using the Roche COBAS® TaqMan AmpliPrep assay. HBV DNA \< 50 IU/mL = approximately 300 copies/mL.
Time frame: At 72 weeks + 24 weeks follow-up
Population: This analysis was planned if \> 10% of treated participants had HBV DNA measurements during the off-treatment follow-up period.
Prothrombin Time (PT) at Week 72
Prothrombin, a liver protein, plays an important role in the extrinsic pathway of clotting. Increased prothrombin time indicates abnormal liver functioning. Normal prothrombin time varies from laboratory to laboratory. Generally, normal prothrombin time varies between 10 to 13.2 seconds. Abnormal PT: \> 1.01 x ULN.
Time frame: At week 72
Population: Treated participants with measures available at week 72.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Entecavir (ETV) | Prothrombin Time (PT) at Week 72 | 13.32 seconds | Standard Error 0.305 |
Total Bilirubin at Week 72
Bilirubin measures are used to diagnose or monitor liver functioning or diseases that include hepatitis. Viral hepatitis is one of the condition in which bilirubin levels are elevated. Normal range varies from laboratory to laboratory. Bilirubin abnormality : =\> 1.1 x ULN mg/dL.
Time frame: At week 72
Population: Treated participants with measures available at week 72.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Entecavir (ETV) | Total Bilirubin at Week 72 | 0.79 mg/dL | Standard Error 0.079 |
