研究概览
简要总结
The purpose of this study is to evaluate the pharmacokinetics (PK), safety, and tolerability of aprepitant for the prevention of post-operative nausea and vomiting (PONV) in pediatric participants.
Post-operative aprepitant plasma concentrations will be evaluated with a non-compartmental analysis (NCA) at each dose and for each age cohort. Full PK profiles analyzed using population PK modeling and simulation will be described in a separate report.
详细描述
Because the opportunity to collect specimens for PK analyses in children will be limited, a flexible sparse sampling scheme using ranges of collection times will be utilized which will limit the burden to participants.

盲法说明
This study will be conducted as a partially blinded study. PK samples will not be collected from participants in the control group. To maintain a partial blind, approximately 3 participants randomly selected from each age group in each of the aprepitant treatment groups will not have PK sampling. All participants will remain blinded to the study treatment. The investigator and Sponsor will be blinded to the study medication in participants not providing PK samples. The investigator and Sponsor will remain blinded to the aprepitant dose given to participants from whom PK samples will be collected.

Percentage of Participants Discontinuing Study Due to an AE
时间窗: From pre-operative phase up to Follow-up (Day 1 to Day 15)
An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product. Any worsening of a pre-existing condition which is temporally associated with the use of the SPONSOR's product, was also an AE. Changes resulting from normal growth and development which did not vary significantly in frequency or severity from expected levels were not to be considered adverse events. Vomiting and retching were not defined as AEs during the period of data collection (24 hours following the end of surgery) unless they met the definition of an SAE. The percentage of participants discontinuing study due to an AE was reported by dose group.
