  Purpose

The purpose of this study is to determine the immunogenicity and safety profile of CSL Limited's Influenza Virus Vaccine compared to a US licensed comparator Influenza Virus Vaccine in a pediatric population aged greater than or equal to 6 months to less than 18 years.


Condition Intervention Phase
Influenza
Biological: CSL's Influenza Virus Vaccine (Afluria)
Biological: Influenza Virus Vaccine (Fluzone)
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Phase III, Randomized, Observer-blind, Multi-center, Noninferiority Comparison of the Immune Response of CSL Limited's Influenza Virus Vaccine Compared to a US Licensed Trivalent Inactivated Split-Virion Influenza Vaccine in a Pediatric Population Aged Greater Than or Equal to 6 Months to Less Than 18 Years.

Primary Outcome Measures:
  • Geometric Mean Titer 30 Days After the Last Study Vaccination [ Time Frame: 30 days after the last study vaccination ] [ Designated as safety issue: No ]
  • Percentage of Participants With Seroconversion 30 Days After the Last Study Vaccination [ Time Frame: 30 days after the last study vaccination ] [ Designated as safety issue: No ]
    Seroconversion rate was defined as the proportion of participants with either a titer of less than 1:10 before vaccination achieving a HI antibody titer of 1:40 or more after vaccination, or a HI titer of 1:10 or more before vaccination achieving a four-fold or greater increase in HI titer after vaccination.


Secondary Outcome Measures:
  • Frequency and Intensity of Local and Systemic Solicited Symptoms, Cohort A (6 Months to < 3 Years) [ Time Frame: 7 days after each vaccination ] [ Designated as safety issue: Yes ]
  • Frequency and Intensity of Local and Systemic Solicited Symptoms, Cohort B [ Time Frame: 7 days after each vaccination ] [ Designated as safety issue: Yes ]
  • Frequency and Intensity of Local and Systemic Solicited Symptoms, Cohort C [ Time Frame: 7 days after vaccination ] [ Designated as safety issue: Yes ]
  • Frequency and Intensity of Unsolicited Adverse Events (UAEs) [ Time Frame: 30 days after each vaccination ] [ Designated as safety issue: Yes ]
    UAE stands for Unsolicited Adverse Events

  • New Onset of Chronic Illnesses (NOCIs) [ Time Frame: 6 months after last study vaccination ] [ Designated as safety issue: Yes ]
    New onset of chronic illness after any vaccine dose. A new onset of chronic illness was defined as the diagnosis of a new medical condition which was chronic in nature, including those potentially controllable by medication (e.g., diabetes, asthma).

  • Serious Adverse Events (SAEs) [ Time Frame: 6 months after last study vaccination ] [ Designated as safety issue: Yes ]
  • Duration of Local and Systemic Solicited Symptoms, Cohort A (6 Months to < 3 Years) [ Time Frame: 7 days after each vaccination ] [ Designated as safety issue: Yes ]
  • Duration of Local and Systemic Solicited Symptoms, Cohort B [ Time Frame: 7 days after each vaccination ] [ Designated as safety issue: Yes ]
  • Duration of Local and Systemic Solicited Symptoms, Cohort C [ Time Frame: 7 days after vaccination ] [ Designated as safety issue: Yes ]
