About this study

Official title: Phase 1 Evaluation of the Safety and Immunogenicity of Live Influenza A Vaccine H7N9 (6-2) AA ca Recombinant (A/Anhui/1/2013 (H7N9) x A/Ann Arbor/6/60 ca), a Live Attenuated Virus Vaccine Candidate for Prevention of Influenza H7N9 Disease in 50 to 70 Year Olds in the Event of a Pandemic

H7N9 viruses have caused an outbreak of severe respiratory disease in 2013-2014 in China that affected many older adults. This study will evaluate the safety of and immune response to a live attenuated H7N9 vaccine in adults 50 to 70 years old.

Read the detailed description

H7N9 viruses caused an outbreak of severe respiratory disease in China in 2013-2014, which was associated with severe respiratory illness, acute respiratory distress syndrome (ARDS), intensive care unit (ICU) admissions, and death. The outbreak affected older adults and highlighted the need for a vaccine that is effective in this population. Prior studies have demonstrated the safety and immunogenicity of a vaccination regimen in which administration of the experimental H7N9 vaccine (H7N9 Anhui 2013/AA ca) was followed by an H7N9 inactivated vaccine in younger adults. This study will evaluate the safety and immunogenicity of a similar vaccination regimen in healthy adults, 50 to 70 years old, who are H7N9 seronegative.

Participants will be admitted to the inpatient unit 2 days before they will receive their first vaccination with the H7N9 Anhui 2013/AA ca vaccine. All participants will receive one dose of the H7N9 vaccine, delivered as a nasal spray, on Day 0. While in the inpatient unit, study procedures will include physical examinations, medical history reviews, nasal swabs, and blood and urine collections. On Day 9, participants will be discharged from the inpatient unit provided they meet certain medical criteria. If not, they will remain in the isolation unit until the criteria are met.

On Day 26, participants will be readmitted to the inpatient unit, and on Day 28, they will receive one dose of the H7N9 vaccine delivered as a nasal spray. Participants will remain in the inpatient unit until Day 37 and will take part in all of the same study procedures that occurred during the first inpatient stay. On Day 56, all participants will attend a study visit for a blood collection and nasal swab. On Day 98, all participants will receive one dose of the inactivated subvirion H7N9 vaccine. They will attend study visits on Days 101, 105, 112, 126, 154, and 180, which will include the same study procedures that occurred during the inpatient visits.

What is being measured

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

  1. Frequency of vaccine-related reactogenicity events (REs) that occur during the acute monitoring (inpatient) phase of the study

    Measured: Measured through Day 37

  2. Area under the curve (AUC) of nasal virus shedding after each dose of vaccine

    Assessed by liquid titration of nasal secretions on Madin Darby canine kidney (MDCK) cells at 33°C

    Measured: Measured through Day 180

  3. Development of serum antibody assessed by either hemagglutination inhibition (HAI) or microneutralization (MN) assays following the H7N9 pLAIV or pIIV doses

    Measured: Measured through Day 180

Secondary outcomes (3)
  1. Development of a significant increase in nasal secretion hemagglutinin (HA)-specific antibody assessed by enzyme-linked immunosorbent assay (ELISA)

    Measured: Measured through Day 180

  2. Development of greater than 200 influenza-specific interferon-gamma-secreting cells per million lymphocytes as assessed by enzyme-linked immuno spot assay (ELISPOT) on Day 28 after immunization

    Measured: Measured through Day 28

  3. Detection of influenza-specific IgG or IgA secreting B cells on Day 7 following pLAIV vaccination assessed by antibody secreting cells (ASC) assay

    Measured: Measured through Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing H7N9 Anhui 2013/AA ca and Inactivated subvirion H7N9 vaccine in people with Influenza A Virus, H7N9 Subtype, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

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 7 inclusion and 26 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 19 Apr 2017. 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 States. 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 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?

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?

Frequency of vaccine-related reactogenicity events (REs) that occur during the acute monitoring (inpatient) phase of the study (time frame: Measured through Day 37). The study lists 3 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 NCT02274545, 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 19 Apr 2017.
