About this study
Official title: A Phase IIb, Partially-Blinded, Randomized, Active Comparator-Controlled Study to Evaluate the Pharmacokinetics/Pharmacodynamics, Safety, and Tolerability of Aprepitant in Pediatric Patients for the Prevention of Post Operative Nausea and Vomiting
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.
Read the detailed description
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.
- Conditions
- Post-operative Nausea, Post-operative Vomiting
- Being tested
- Aprepitant, Placebo to Aprepitant, Ondansetron, Placebo to match ondansetron

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
Detailed description
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.

Percentage of Participants Experiencing at Least One Adverse Event (AE)
Time frame: 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 experiencing ≥1 AE was reported by dose group.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Concentration-time Curve of Aprepitant From Time 0 to the Last Measurable Concentration (AUC0-last) Following Administration of 125 mg Dose Equivalent in 12 to 17 Year Age Group (time frame: 30-60 minutes pre-administration, 2-4 hours post administration, 5-7 hours post administration, 8-10 hours post administration). The study lists 41 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01732458, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2018.
