Primary Outcome Measures

Number of Participants With Serious Adverse Events (SAE) and Discontinuations Due to Adverse Events (AEs) - On Treatment
AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Medical Dictionary for Regulatory Activities (MedDRA) version 16.0 was used.

Secondary Outcome Measures

Mean Maximum Observed Plasma Concentration (Cmax) and Mean Trough Observed Plasma Concentration (Cmin) of Entecavir in LVD-naive and LVD-experienced Participants, by Age Cohort
Cmax and Cmin were derived from plasma concentration of ETV versus time and measured in nanograms per milliliters (ng/mL). Blood samples were obtained before study drug administration and at 0.5, 1, 2, 4, 8, and 24 hours after study drug administration on Day 14 (+/- 4 days) for the PK assessment. Plasma samples were analyzed for ETV with a validated method using liquid chromatography-tandem mass spectrometry detection. Note: PK parameters were summarized for only Groups A and B. PK assessment was optional for Group C participants (NA-experienced participants who were included with the September 2011 country-specific protocol amendment). No Group C participants chose to participate in the PK assessment.
Median Time of Maximum Observed Plasma Concentration (Tmax) in LVD-naive and LVD-experienced Participants, by Age Cohort

Mean Area Under the Concentration-Time Curve in One Dosing Interval [AUC(TAU)] of Entecavir in LVD-naive and LVD-experienced Participants, by Age Cohort
Area under the Curve (AUC) was derived from plasma concentration of ETV versus time. AUC(TAU) was calculated by log- and linear trapezoidal summations, TAU = 24 hours, and was measured in nanograms*hours per milliliter (ng*h/mL). Blood samples were obtained before study drug administration and at 0.5, 1, 2, 4, 8, and 24 hours after study drug administration on Day 14 (+/- 4 days) for the PK assessment. Plasma samples were analyzed for ETV with a validated method using liquid chromatography-tandem mass spectrometry detection.
