What is being measured

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

  1. The primary endpoint is viral AUC as calculated in cell culture of nasal swabs (quantitation of nasal swabs for viral infectivity by cell culture), from initiation of VX-787 treatment

    Measured: up to 11 days

Secondary outcomes (12)
  1. Safety and tolerability based on assessment of adverse events, clinical laboratory assessments, 12-lead electrocardiograms (ECGs), and vital signs.

    Measured: up to 33 days

  2. Total tissue count and total mucus weight after viral inoculation

    Measured: up to 10 days

  3. Sequence analysis of the relevant target region of influenza

    Measured: up to 8 days

  4. Pharmacokinetic (PK) parameters of VX-787

    As measured by AUC, Cmax, tmax

    Measured: 8 days

  5. Composite symptom score AUC

    Measured: up to 8 days

  6. Viral AUC calculated by RT-PCR of nasal swabs, from initiation of VX-787 treatment

    Measured: up to 8 days

  7. Duration of viral shedding by cell culture and/or RT-PCR

    Measured: up to 8 days

  8. Peak viral shedding titer by cell culture and/or RT-PCR

    Measured: up to 8 days

  9. Time to resolution from peak viral shedding by cell culture and/or RT-PCR

    Measured: up to 8 days

  10. Time to peak of composite sympton score, duration, and time to resolution of composite score from peak

    Measured: up to 8 days

  11. Peak severity of symptoms after viral inoculation

    Measured: up to 8 days

  12. Duration of influenza-like illness after viral inoculation

    Measured: up to 8 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VX-787 in people with Influenza Virus, run by Vertex Pharmaceuticals Incorporated at 1 site in United Kingdom.

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 2 inclusion and 11 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 2 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The primary endpoint is viral AUC as calculated in cell culture of nasal swabs (quantitation of nasal swabs for viral infectivity by cell culture), from initiation of VX-787 treatment (time frame: up to 11 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Sep 2016; AzTrials last refreshed its copy on 8 Nov 2026.
