Immunogenicity and Safety of Fluzone® Quadrivalent, Southern Hemisphere 2015 Formulation (Intramuscular Route)

Phase 4

Completed

Conditions: Influenza

Interventions: Biological: Fluzone Quadrivalent Influenza Vaccine

Registration Number: NCT03546192

Lead Sponsor: Sanofi Pasteur, a Sanofi Company

Brief Summary: The aim of the study was to assess the immunogenicity and safety of Fluzone Quadrivalent influenza vaccine Southern Hemisphere (SH) 2015 formulation in participants aged 18 to 60 years as well as in participants 61 years or older.

The objectives were:

* To evaluate the compliance, in terms of immunogenicity, of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation with the requirements of the European Medicines Agency (EMA) Note for guidance (NfG) CPMP/BWP/214/96

* To describe the immunogenicity of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation

* To describe the safety of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation

Detailed Description: All participants received 1 intramuscular dose of Fluzone Quadrivalent vaccine at the first visit.

Immunogenicity and safety were assessed in all participants. Adverse events (AE) defined in EMA NfG CPMP/BWP/214/96 were collected for 3 days after vaccination, solicited AE pre-listed in the diary card were collected for 7 days after vaccination, unsolicited AEs were collected for 21 days after vaccination, and serious adverse event (SAE) information was collected throughout the study.

Self-reported thrombocytopenia, which may be a contraindication for intramuscular vaccination, at the discretion of the Investigator.
Vaccination against influenza in the previous 12 months if administered in the context of a clinical trial or a flu vaccination campaign.
Known systemic hypersensitivity to eggs, chicken proteins, or any of the vaccine components, or a history of a life-threatening reaction to the vaccine or to a vaccine containing any of the same substances (the complete list of vaccine components is included in the Prescribing Information) .
Receipt of immune globulins, blood, or blood-derived products in the past 3 months.
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.
Participant was pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to vaccination and until at least 3 weeks after vaccination).
Any condition that in the opinion of the Investigator would pose a health risk to the participant 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).
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 (HIV), hepatitis B, or hepatitis C, as reported by the participant. (No screening procedures were implemented.)
Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.
Current alcohol or drug addiction that, in the opinion of the Investigator, might interfere with the ability to comply with trial procedures.
Moderate or severe acute illness/infection (according to Investigator judgment) or febrile illness (temperature ≥ 38°C) on the day of vaccination. A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided.
Identified as an Investigator or employee of an Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e. parent, spouse, natural or adopted child) of an Investigator or employee with direct involvement in the proposed study.

Arm && Interventions

Group	Intervention	Description
Fluzone Quadrivalent Influenza Vaccine: 18 to 60 Years	Fluzone Quadrivalent Influenza Vaccine	Participants aged 18 to 60 years received one 0.5-mL dose of Fluzone Quadrivalent influenza vaccine, intramuscularly, at Day 0.
Fluzone Quadrivalent Influenza Vaccine: 61 Years or Older	Fluzone Quadrivalent Influenza Vaccine	Participants aged 61 years or older received one 0.5-mL dose of Fluzone Quadrivalent influenza vaccine, intramuscularly, at Day 0.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Seroprotection to Influenza Vaccine Antigens at Day 0 (Pre-vaccination) and Day 21 (Post-vaccination)	Day 0 (pre-vaccination) and Day 21 (post-vaccination)	Anti-influenza antibodies were measured using hemagglutination-inhibition (HAI) assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, B Yamagata lineage. Seroprotection was defined as an antibody titer \>=40 (1/dilution \[dil\]) at pre-vaccination and post-vaccination.
Geometric Mean Titers (GMTs) of Influenza Vaccine Antibodies at Day 0 (Pre-vaccination) and Day 21 (Post-vaccination)	Day 0 (pre-vaccination) and Day 21 (post-vaccination)	Anti-influenza antibodies were measured using a HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, B Yamagata lineage.
Geometric Mean Titer Ratio (GMTR) of Influenza Vaccine Antibodies	Day 0 (pre-vaccination), Day 21 (Post-vaccination)	Anti-influenza antibodies were measured using HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, B Yamagata lineage. Geometric mean titer ratio was calculated as geometric mean titer at Day 21 divided by geometric mean titer at day 0 for each specified group.
Number of Participants With Seroconversion or Significant Increase to Influenza Vaccine Antigens	21 days post-vaccination	Anti-influenza antibodies were measured using HAI assay for 4 strains: A/H1N1, A/H3N2, B Victoria lineage, B Yamagata lineage. Seroconversion was defined as participants with a pre-vaccination titer \<10 (1/dil) and a post-vaccination titer \>= 40 (1/dil). Significant increase was defined as a pre-vaccination titer \>= 10 (1/dil) and \>= 4-fold increase in post vaccination titer. Number of participants with seroconversion or significant increase to Influenza vaccine antigens were reported.
Number of Participants Reporting Solicited Reactions Listed in the Committee for Medicinal Products for Human Use (CHMP) Note for Guidance	Within 3 days after vaccination	Solicited reactions listed in the CHMP note for guidance included: injection site induration \>= 50 mm for at least 4 consecutive days , injection site ecchymosis, temperature \> 38.0°C for at least one day, malaise, and shivering.
Number of Participants Reporting Solicited Injection Site and Systemic Reactions	Within 7 days after vaccination	A solicited reaction is an adverse event (AE) that is pre-listed in the electronic case report form (eCRF) and considered to be related to vaccination. Solicited injection site reactions: Pain (Grade 1: no interference with activity, Grade 2: some interference with activity, Grade 3: significantly prevent daily activity), erythema, swelling, induration, and ecchymosis (Grade 1: \>=25 mm to \<= 50 mm, Grade 2: \>=51 to \<=100 mm, Grade 3: \> 100 mm). Solicited systemic reactions: Fever (Grade 1: \>=38.0 degree Celsius (°C) to \<=38.4°C, Grade 2: \>=38.5°C to \<=38.9 °C, Grade 3: \>= 39°C), headache, malaise, myalgia, and shivering (Grade 1: no interference with activity, Grade 2: some interference with activity, Grade 3: significantly prevent daily activity). Number of participants with any of the Grade 1, 2 or 3 solicited injection-site and systemic reactions and Grade 3 solicited injection-site and systemic reactions were reported.
