Immunogenicity and Safety of a Single 0.5 mL Dose of Inflexal V With a 0.25 mL 2-dose Regimen of Inflexal V

January 7, 2014 updated by: Crucell Holland BV

A Phase III Open, Randomized, Parallel, Multi-center Study in Children Aged 6 - 35 Months to Compare the Immunogenicity and Safety of a Single 0.5 mL Dose of Inflexal V With a 0.25 mL 2-dose Regimen of Inflexal V Administered According to a 0/4 Week Schedule

The study aims to evaluate the immunogenicity of a single full (0.5 mL) dose and a 0.25 mL 2-dose regime of Inflexal V in unprimed children aged 6 - <36 months, using the EMA guideline for the re-registration of the seasonal influenza vaccine in adults (aged ≥18 ≤60 years) as reference.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 months to 2 years (CHILD)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Number of Participants With Local and Systemic Adverse Events as a Measure of Safety and Tolerability
Time Frame: Solicited local and systemic AEs were collected from Day 1 (day of vaccination) to Day 4 inclusive using a subject diary
