Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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
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
Other Names:
  • SCH 503034
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

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
