Safety and Immunogenicity of an Adjuvanted Trivalent Influenza Vaccine in Children 6 to <72 Months of Age in Mexico.

30. November 2016 aktualisiert von: Novartis Vaccines

A Phase 3, Observed-Blind, Randomized, Multi-center Study to Evaluate Safety and Immunogenicity of an Adjuvanted Trivalent Influenza Vaccine in Children 6 to <72 Months of Age in Mexico.

The administration of adjuvanted Trivalent Influenza Vaccine (aTIV) has come to result in a more immunogenic and effective response compared with conventional influenza vaccines in elderly and adults.

The aim of this study is to evaluate safety and immunogenicity of Novartis aTIV in children 6 to <72 months of age, Mexican population, in comparison to Fluzone, a non-adjuvanted trivalent influenza vaccine (TIV).

Beschreibung

Inclusion Criteria:

  • Individuals who can comply with study procedures.
  • Willingness to allow for serum samples to be stored beyond the study period, for potential additional future testing to better characterize immune response.

Exclusion Criteria:

  • Any fatal prognosis of an underlying medical condition (<12 month life expectancy).
  • Clinical conditions representing a contraindication to intramuscular vaccination and blood draws.

  • Abnormal function of the immune system resulting from:

    1. Clinical conditions.
    2. Systemic administration of corticosteroids (PO/IV/IM) for more than 14 consecutive days within 90 days prior to informed consent.
    3. Administration of antineoplastic and immunomodulating agents or radiotherapy within 90 days prior to informed consent.
  • Received immunoglobulins or any blood products within 180 days prior to informed consent.
  • Received an investigational or non-registered medicinal product within 30 days prior to informed consent.
  • Study personnel as an immediate family or household member.
  • Any other clinical condition that, in the opinion of the investigator, might interfere with the results of the study or pose additional risk to the subject due to participation in the study.
  • Received any influenza vaccine (licensed or investigational) or with laboratory confirmed influenza within 6 months prior enrollment.
  • Received any other vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrolment in this study or who are planning to receive any vaccine within 28 days from the study vaccines.

Antibody response was assessed in terms of GMTs in all three homologous virus strains, 21 days after last immunization, in subjects 6 to <72 months of age.

The study is considered a success if the 21 days after last immunization GMT ratios of aTIV relative to TIV demonstrate as non-inferior with the lower limit (LL) of the two sided 95% confidence interval (CI) above 0.67 (-0.176 on log10 scale) for each vaccine strain (Center for Biologics Evaluation and Research {CBER} Guideline on Seasonal Vaccines May 2007).

GMRs of HI, day 22/day 1 (non-naive subjects) or day 50/day 1 (naive subjects) in all three homologous virus strains, 21 days after last immunization, in subjects 6 to <72 months of age. As the non-inferiority of aTIV to TIV has been established, GMT ratio of aTIV relative to TIV in all three homologous virus strains, 21 days after last immunization in subjects 6 to <72 months of age was evaluated using margins greater than the non-inferiority cut-off of 0.67.
