Trial Outcomes & Findings for A Study of Entecavir in Pediatric Patients With Chronic Hepatitis B Virus (HBV)-Infection (NCT NCT00423891)
NCT ID: NCT00423891
Last Updated: 2018-05-02
Results Overview
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.

Participant Flow
64 enrolled. 48 treated. Participants received a minimum of 48 weeks study drug but depending on response to drug, could remain on treatment for up to a total of 120 weeks. Participants were to receive post dosing follow up after last dose, for a total of 5 years on-study (on and off study drug).

Lamivudine (LVD)-Naive (Group A)
Participants with less than (\<) 1 week of prior LVD therapy and with no LVD therapy within 24 weeks prior to enrollment were included in Group A. Prior to Pharmacokinetic (PK) assessment, Cohort 1 (age ≥ 2 years to ≤ 6 years) and Cohort 2 (\>6 years to ≤ 12 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, once a day (QD) and Cohort 3 (age \>12 years to ≤18 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, or ETV tablets, 0.5 mg, QD. Following PK analysis, those who met the specified dosing requirements (at least 0.5 mg/day) and could tolerate swallowing ETV tablets were allowed to choose either formulation. Entecavir (ETV) was administered for a maximum of 120 weeks.

Lamivudine (LVD)-Experienced (Group B)
Participants with greater than (\>) 12 weeks of prior LVD therapy were included in Group B. Prior to PK assessment, Cohort 1 (age ≥ 2 years to ≤ 6 years) and Cohort 2 (\> 6 years to ≤ 12 years) received ETV oral solution, 0.030 mg/kg up to 1.0 mg, QD and Cohort 3 (age \>12 years to ≤18 years) received ETV oral solution, 0.030 mg/kg up to 1.0 mg, or ETV tablets, 1.0 mg QD. Following PK analysis, those who met the specified dosing requirements (at least 1.0 mg/day) and could tolerate swallowing ETV tablets were allowed to choose either formulation. Entecavir (ETV) was administered for a maximum of 120 weeks.

Nucleoside/Tide Analog (NA) - Experienced (Group C)
Participants who failed previous treatment with any non-ETV nucleoside/tide analog (NA) were included in Group C, starting in 2011. PK assessment was optional to participants in Group C. All participants received ETV oral solution, 0.030 mg/kg up to 1.0 mg, or ETV tablets, 1.0 mg, QD. Participants who met the specified dosing requirements (at least 1.0 mg/day for NA-experienced participants) and could tolerate swallowing ETV tablets were allowed to choose either formulation. ETV was administered for a maximum of 120 weeks.

SECONDARY outcome
Timeframe: Day 14Population: Participants in Groups A and B who received study drug and had PK assessment.
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.

SECONDARY outcome
Timeframe: Day 14Population: Participants in Groups A and B who received study drug and had PK assessment.
Tmax was derived from plasma concentration of ETV versus time and measured in hours (h). 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. Age categories presented below: participants age as of first day of dosing. 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.

SECONDARY outcome
Timeframe: Day 14Population: Participants in Groups A and B who received study drug and had PK assessment.
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. 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.

SECONDARY outcome
Timeframe: Baseline through Week 96Population: The intent-to-treat method of Non-Completer = Failure was used through Week 48 in which all treated participants were analyzed, and participants with missing data at the analysis week were considered failures. After Week 48, the method of Non-Completer = Missing was used, in which participants with missing data at the analysis week were excluded.
Hepatitis B virus DNA by PCR was measured using the Roche COBAS TaqMan - HPS assay and was reported in IU/mL. LLQ = 29 IU/mL. Baseline was the last value measured prior to or on the date of the first dose of study therapy.

Lamivudine (LVD)-Naive (Group A)
n=24 Participants
Participants with less than (\<) 1 week of prior LVD therapy and with no LVD therapy within 24 weeks prior to enrollment were included in Group A. Prior to Pharmacokinetic (PK) assessment, Cohort 1 (age ≥ 2 years to ≤ 6 years) and Cohort 2 (\>6 years to ≤ 12 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, once a day (QD) and Cohort 3 (age \>12 years to ≤18 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, or ETV tablets, 0.5 mg, QD. Following PK analysis, those who met the specified dosing requirements (at least 0.5 mg/day) and could tolerate swallowing ETV tablets were allowed to choose either formulation. Entecavir (ETV) was administered for a maximum of 120 weeks.

Nucleoside/Tide Analog (NA) - Experienced (Group C)
n=5 Participants
Participants who failed previous treatment with any non-ETV nucleoside/tide analog (NA) were included in Group C, starting in 2011. PK assessment was optional to participants in Group C. All participants received ETV oral solution, 0.030 mg/kg up to 1.0 mg, or ETV tablets, 1.0 mg, QD. Participants who met the specified dosing requirements (at least 1.0 mg/day for NA-experienced participants) and could tolerate swallowing ETV tablets were allowed to choose either formulation.

Timeframe: Baseline to Week 96Population: The intent-to-treat method of Non-Completer = Failure was used through Week 48 in which all treated participants were analyzed, and participants with missing data at the analysis week were considered failures. After Week 48, the method of Non-Completer = Missing was used, in which participants with missing data at the analysis week were excluded.
Hepatitis B virus DNA by PCR was measured using the Roche COBAS TaqMan - HPS assay and was reported in IU/mL. Baseline was the last value measured prior to or on the date of the first dose of study therapy. Normalization in ALT= ALT ≤ 1.0\*ULN.

Lamivudine (LVD)-Naive (Group A)
n=24 Participants
Participants with less than (\<) 1 week of prior LVD therapy and with no LVD therapy within 24 weeks prior to enrollment were included in Group A. Prior to Pharmacokinetic (PK) assessment, Cohort 1 (age ≥ 2 years to ≤ 6 years) and Cohort 2 (\>6 years to ≤ 12 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, once a day (QD) and Cohort 3 (age \>12 years to ≤18 years) received ETV oral solution, 0.015 mg/kg up to 0.5 mg, or ETV tablets, 0.5 mg, QD. Following PK analysis, those who met the specified dosing requirements (at least 0.5 mg/day) and could tolerate swallowing ETV tablets were allowed to choose either formulation. Entecavir (ETV) was administered for a maximum of 120 weeks.
