Participant Flow

This study originally intended to enroll 3 age-based pediatric cohorts. However the study was terminated after the completion of Cohort 1. No participants were enrolled in either Cohorts 2 or 3. Only data from Cohort 1 was collected.

Measure
Cohort 1: Children 17 to ≥13 Years
Participants were administered a single dose of boceprevir powder mixed in a suitable vehicle such pudding or applesauce. The first 4 participants were treated with a 11.4 mg/kg dose of boceprevir powder. The dose/weight ratio may be adjusted for the next 12 participants based on the evaluation of the PK, safety, and tolerability data from the first 4 participants.
Cohort 2: Children <13 to ≥7 Years
Participants were administered a single dose of boceprevir powder mixed in a suitable vehicle such as pudding or applesauce. The first 4 participants were treated with boceprevir at a dose contingent on the PK and safety results in Cohort 1. The dose/weight ratio may be adjusted for the next 12 participants based on the evaluation of the PK, safety, and tolerability data from the first 4 participants.
Cohort 3: Children <7 to ≥3 Years
Participants were administered a single dose of boceprevir powder mixed in a suitable vehicle such as pudding or applesauce. The first 4 participants were treated with boceprevir at a dose contingent on the PK and safety results in Cohort 2. The dose/weight ratio may be adjusted for the next 12 participants based on the evaluation of the PK, safety, and tolerability data from the first 4 participants.
