About this study

Official title: A Prospective, Randomized, Double-Blind, Placebo-Controlled Trial to Compare the Safety, Tolerability, Immunogenicity and Efficacy of One Dose and Two Doses of a Liquid Formulation of Influenza Virus Vaccine, Trivalent, Types A & B, Live Cold-Adapted (CAIV-T) Compared With Placebo in Healthy Children

The purpose of this study is to determine the efficacy of the liquid formulation of CAIV-T against culture confirmed influenza illness in healthy children aged at least 6 months and less than 36 months.

What is being measured

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

  1. The primary endpoint for efficacy is the first episode in the first season in a study child of a culture-confirmed influenza illness, caused by community-acquired subtypes antigenically similar to those contained in the vaccine.

Secondary outcomes (1)
  1. The first episode in the second season in a study child of a culture-confirmed influenza illness, caused by community-acquired subtypes antigenically similar to those contained in the vaccine.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CAIV-T in people with Healthy, run by MedImmune 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 12 inclusion and 32 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 3 Oct 2006. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 for efficacy is the first episode in the first season in a study child of a culture-confirmed influenza illness, caused by community-acquired subtypes antigenically similar to those contained in the vaccine.. 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 NCT00192400, 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 3 Oct 2006.
