About this study

Official title: MK0869 and MK0517 Time-on-Target PET Study

This study will evaluate if the mean value of brain neurokinin 1 (NK1)-receptor occupancy of participants treated with aprepitant is similar to that of participants treated with fosaprepitant at certain timepoints.

Read the detailed description

The third arm of the study (Aprepitant 250 mg) will only be conducted if the real-time assessment of the NK1-receptor occupancy data between fosaprepitant 150 mg \& aprepitant 165 mg reveals that the primary hypothesis will not be supported.

Being tested
Fosaprepitant 150 mg, Aprepitant 165 mg, Aprepitant 250 mg, Dexamethasone (12-8-16-16 mg), Dexamethasone (12-8-8-16 mg)

  • OndansetronDrug

    The intravenous (I.V.) infusion of ondansetron 32 mg will begin 30 minutes after the start of fosaprepitant dimeglumine or 30 minutes after aprepitant on Day 1 and will be administered as a 15-minute infusion

  • MK0999Drug

    I.V. infusion of MK0999 containing ~100 MBq (~3 mCi) containing ≤ 5 ug of MK0999)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Brain NK1-receptor Occupancy at 24 Hours Post Dose

    Measured: 24 hours post dose

  2. Brain NK1-receptor Occupancy at 48 Hours Post Dose

    Measured: 48 hours post dose

Secondary outcomes (2)
  1. Brain NK1-receptor Occupancy at the Time of the Maximum Concentration (Tmax)

    Measured: 30 minutes after the end of the 20-minute infusion of fosaprepitant or at 4 hours after oral dosing of aprepitant

  2. Brain NK1-receptor Occupancy at 120 Hours Post Dose

    Measured: 120 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Fosaprepitant 150 mg, Aprepitant 165 mg and Aprepitant 250 mg in people with Chemotherapy-Induced Nausea and Vomiting (CINV), run by Merck Sharp & Dohme LLC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 3 Nov 2011). 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?

Brain NK1-receptor Occupancy at 24 Hours Post Dose (time frame: 24 hours post dose). The study lists 2 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 NCT01111851, 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 Feb 2015.
