  • The subject/parents are able to understand and comply with the planned study procedures, including being available for all study visits.
  • The subject/parents have provided informed consent prior to any study procedures. (An assent will be obtained for all children as required by the institutional IRB (Institutional Review Board.)

Who cannot join

  • Subjects with a laboratory documented history of previous novel H1N1 infection.
  • History of egg allergy or allergy to other components of vaccine.
  • History of wheezing.
  • The subject is immunosuppressed as a result of an underlying illness or treatment with immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation therapy.
  • The subject has an active neoplastic disease.
  • The subject has long-term (greater than 2 weeks) use of oral or parenteral steroids, or high-dose inhaled steroids (>800 mg/day of beclomethasone dipropionate or equivalent) within the preceding 6 months (nasal and topical steroids are allowed).

About this study

Official title: Evaluation of the Effect of Age and Prior Immunity on the Response to Live or Inactivated Seasonal (A/California/7/2009-like, A/Perth/16/2009-like, and B/Brisbane/60/2008-like (B/Victoria Lineage) Influenza Vaccines in Children

A total of 88 children between 2 and 9 years of age will be randomized to receive a two dose schedule of either licensed live attenuated trivalent seasonal influenza vaccine (LAIV) or licensed inactivated seasonal influenza vaccine (TIV)or TIV followed by LAIV or LAIV followed by TIV separated by 28 days. Children with a laboratory documented history of prior H1N1 infection will be excluded.

Read the detailed description

The study will be conducted as a randomized, prospective, open-label evaluation of the clinical tolerability, vaccine virus shedding, and serum and mucosal antibody response to vaccination with either live trivalent influenza vaccine (LAIV) or trivalent influenza vaccine (TIV) in healthy children between the ages of 2 and 9 years. Children will be screened for antibody to A/Brisbane/57/07 (H1N1) and A/California/07/09 (H1N1), A/Perth/16/2009 (H3N2) and B/Brisbane/60/2008 before and at indicated times after the start of the study. They will not be randomized based on antibody levels. Children with prior documented infection with the 2009 pandemic H1N1 virus will be excluded. Vaccine will be administered on days 0 and 28.

Safety of vaccination will be assessed using symptoms collected by parents for 7 days after each dose of vaccine. Serum will be obtained prior to and on day 28 following each dose of vaccine and assessed for antibody by HAI, ELISA, and neutralization techniques. Nasal secretions will be obtained by nasal wick prior to and on day 28 after each dose and assessed for HA-specific IgA (immune globulin A) and IgG (immune globulin G)antibody by ELISA. Nasal swabs will be obtained on days 2, 4, and 7 after each dose of live vaccine and assessed for the presence and magnitude of vaccine virus shedding of the live attenuated vaccine by rtRT-PCR (real-time reverse transcriptase polymerase chain reaction)and TCID50 (50% tissue culture infectious doses)on MDCK(Madin Darby Canine Kidney) cells.

What is being measured

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

  1. Number of Subjects Shedding Vaccine Virus of Each Subtype by PCR

    Nasal washes were collected on days 2, 4 and 7 after vaccination. Nasal swab specimens were tested for the presence of vaccine viruses by quantitative viral culture in MDCK cells at 33º C and by real-time quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) amplification. The limit of detection of vaccine viruses was 10^0.6 tissue culture infectious doses (50%)/ml for virus culture and 10^0.4 tissue culture infectious doses (50%)/ml for qRT-PCR.

    Measured: baseline to day 7

Secondary outcomes (6)

  1. Mean Peak H1N1 Virus Titer, Dose 1

    After the first dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

    Measured: days 2, 4 and 7

  2. Mean Peak H3N2 Virus Titer, Dose 1

    After the first dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

    Measured: days 2, 4 and 7

  3. Mean Peak Influenza B Virus Titer, Dose 1

    After the first dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

    Measured: days 2, 4 and 7

  4. Mean Peak H1N1 Virus Titer, Dose 2

    After the second dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

    Measured: days 2, 4 and 7

  5. Mean Peak H3N2 Virus Titer, Dose 2

    After the second dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

    Measured: days 2, 4 and 7

  6. Mean Peak Influenza B Virus Titer, Dose 2

    After the second dose of vaccine, the virus titer from nasal secretions was measured in tissue culture on days 2, 4 and 7 and the highest titer from one of those three time points was reported.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Live attenuated Influenza vaccine, Trivalent Influenza Vaccine and TIV followed by LAIV in people with Influenza, run by University of Rochester at 2 sites 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 5 inclusion and 15 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 29 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 19 Oct 2016). 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?

Number of Subjects Shedding Vaccine Virus of Each Subtype by PCR (time frame: baseline to day 7). 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 NCT01246999, which also lists 11 linked publications.

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 29 Dec 2016; AzTrials last refreshed its copy on 8 Nov 2026.
