Study arms

  • Experimental
    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.

    Drug: Boceprevir

  • Experimental
    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.

    Drug: Boceprevir

  • Experimental
    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.

    Drug: Boceprevir

Interventions

  • Single dose of boceprevir powder prior to breakfast in a dosing vehicle of chocolate pudding (i.e., a mousse or custard), apple sauce, Nutella, fruit pudding such as strawberry, cherry, or raspberry pudding, or yogurt or a similar semi-solid product into which the boceprevir powder can be evenly stirred

  2. Maximum Plasma Concentration (Cmax) of Single Dose Boceprevir

    The maximum observed plasma concentration of boceprevir across sampling intervals was determined.

    Time frame: 0 (pre-dose), 0.5, 1, 2, 2.5, 4.5, 5.5, 8, and 10 hours post dose

  3. Time of Maximum Plasma Concentration (Tmax) of Single Dose Boceprevir

    The time at which the maximum plasma boceprevir concentration was observed.

    Time frame: 0 (pre-dose), 0.5, 1, 2, 2.5, 4.5, 5.5, 8, and 10 hours post dose

  4. Final Dose of Boceprevir By Age Group

Adverse events

Collected over Nonserious adverse events (AEs) and serious AEs (SAEs) were collected during the time of boceprevir administration until the final PK sample was collected on Day 1.. Non-serious events are listed at a 5% frequency threshold.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 11, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
