Condition(s) targeted: Influenza

Intervention: Fluzone® Quadrivalent Influenza Vaccine, No Preservative (Biological); Fluzone® Quadrivalent Influenza Vaccine, No Preservative (Biological)

Phase: Phase 4

Status: Active, not recruiting

Summary

The study will evaluate the safety and immunogenicity of the 2014-2015 formulation of Fluzone Quadrivalent vaccine, administered in a 1- or 2-dose schedule, in accordance with the Advisory Committee on Immunization Practices (ACIP) recommendations, in children 6 months to < 9 years of age. Objective:

- To describe the safety of the 2014-2015 formulation of Fluzone Quadrivalent vaccine,

administered in a 1- or 2-dose schedule, in accordance with ACIP recommendations, in children 6 months to < 9 years of age. Observational objectives:

- To describe the immunogenicity of the 2014-2015 formulation of Fluzone Quadrivalent

vaccine, administered in a 1- or 2-dose schedule in accordance with ACIP recommendations, in children 6 months to < 9 years of age.

- To submit available sera from each subject to Center for Biologics Evaluation and

Research (CBER) for further analysis by the WHO, the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to support formulation recommendations for subsequent influenza vaccines.

Clinical Details

Official title: Safety and Immunogenicity Among Healthy Children Receiving Fluzone Quadrivalent, Influenza Vaccine (2014-2015 Formulation)

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: Number of participants reporting solicited injection-site and systemic events and unsolicited adverse events following vaccination with Fluzone® Quadrivalent vaccine.

Secondary outcome:

Geometric mean titers of antibodies to vaccine antigens following final vaccination with Fluzone® Quadrivalent vaccine

Seroprotection with respect to vaccine antigens following vaccination with Fluzone® Quadrivalent vaccine

Seroconversion with respect to vaccine antigens following vaccination with Fluzone® Quadrivalent vaccine

Detailed description: Participants will be assigned to the appropriate age group based on the age at the time of enrollment. Participants will receive a dose of Fluzone Quadrivalent vaccine, those for whom 2 doses of influenza vaccine are recommended per ACIP guidance, will receive a second dose during Visit 2 (28 days after Visit 1). Solicited adverse event (AE) information will be collected for 7 days after each vaccination, unsolicited AE information will be collected from Visit 1 to Visit 2, or to Visit 3 for those subjects receiving 2 doses. Serious adverse event (SAE) information will be collected the study. Immunogenicity will be evaluated in all participants prior to vaccination and at Day 28 after the final vaccination.

Eligibility

Minimum age: 6 Months. Maximum age: 8 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Subject is 6 months to < 9 years of age on the day of first study vaccination (study

product administration)

- Subject and parent/legally acceptable representative are willing and able to attend

scheduled visits and to comply with the study procedures during the entire duration of the study.

- Assent form has been signed and dated by subjects 7 to < 9 years of age, and informed

consent form has been signed and dated by parent(s) or another legally acceptable representative for subjects 6 months to < 9 years of age.

- For subjects 6 months to < 12 months of age, born at full term of pregnancy (≥ 37

weeks) and with a birth weight ≥ 2. 5 kg (5. 5 lbs). Exclusion Criteria:

- Known systemic hypersensitivity to eggs, chicken proteins, or any of the vaccine

components, or a history of a life-threatening reaction to Fluzone Quadrivalent vaccine or to a vaccine containing any of the same substances (the complete list of vaccine components is included in the Prescribing Information).

- History of serious adverse reaction to any influenza vaccine.

- Receipt of any vaccine within 30 days before receiving study vaccine, or plans to

receive another vaccine before Visit 2 for subjects receiving 1 dose of influenza vaccine or Visit 3 for subjects receiving 2 doses of influenza vaccine.

- Participation in another interventional clinical trial investigating a vaccine, drug,

medical device, or medical procedure in the 30 days preceding the first study vaccination or during the course of the study unless no intervention for the other study occurred within the 30 days prior to the first study vaccination and none are planned before the subject would complete safety surveillance for the present study.

- Prior vaccination with any formulation of 2014-2015 influenza vaccine.

- Bleeding disorder or receipt of anticoagulants in the 3 weeks preceding inclusion,

which may be a contraindication for intramuscular vaccination, at the discretion of the Investigator.

- Thrombocytopenia, which may be a contraindication for intramuscular vaccination, at

the discretion of the Investigator.

- Any condition that in the opinion of the Investigator would pose a health risk to the

subject if enrolled or could interfere with the evaluation of the vaccine.

- Personal history of Guillain-Barré Syndrome.

- Known or suspected congenital or acquired immunodeficiency; or receipt of

immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).

- Personal history of clinically significant developmental delay (at the discretion of

the Investigator), neurologic disorder, or seizure disorder.

- Chronic illness that, in the opinion of the Investigator, is at a stage where it

might interfere with trial conduct or completion.

- Known seropositivity for human immunodeficiency virus, hepatitis B, or hepatitis C.

- Moderate or severe acute illness/infection (according to Investigator judgment) on

the day of vaccination or febrile illness (temperature ≥ 100. 4°F). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided.

- Receipt of immune globulins, blood, or blood-derived products in the past 3 months.

- Identified as a natural or adopted child of the Investigator or an employee with

direct involvement in the proposed study.
