4 CONTRAINDICATIONS

A severe allergic reaction (e.g., anaphylaxis) to any component of the vaccine [see Description (11) ], including egg protein, or to a previous dose of any Fluad vaccine is a contraindication to administration of Fluad.

Severe allergic reaction to any component of the vaccine, including egg protein, or after previous dose of any Fluad vaccine. (4)

5 WARNINGS AND PRECAUTIONS

5.1 Guillain-Barré Syndrome

If Guillain-Barré syndrome (GBS) has occurred within 6 weeks following previous Fluad vaccination, the decision to give Fluad should be based on careful consideration of the potential benefits and risks. The 1976 swine Fluad vaccine was associated with an elevated risk of GBS. Evidence for a causal relation of GBS with other Fluad vaccines is inconclusive; if an excess risk exists, it is probably slightly more than 1 additional case per 1 million persons vaccinated.

5.2 Preventing and Managing Allergic Reactions

Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of the vaccine.

5.3 Altered Immunocompetence

If Fluad is administered to immunocompromised persons, including those receiving immunosuppressive therapy, the expected immune response may not be obtained.

5.4 Limitations of Vaccine Effectiveness

Vaccination with Fluad may not protect all recipients.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse event rates observed in the clinical trial(s) of a vaccine cannot be directly compared to rates in the clinical trial(s) of another vaccine and may not reflect the rates observed in practice.

Two clinical studies have evaluated the safety of Fluad.

Study 1 (NCT00391053, see http://clinicaltrials.gov) was a multi-center, double-blind pre-licensure trial conducted in the US. In this study, adults 65 years of age and older were randomized to receive either Fluad or Fluzone (2006-2007 formulation). The study compared the safety and immunogenicity of Fluad to those of Fluzone. The safety analysis set included 2573 Fluad recipients and 1260 Fluzone recipients.

Table 1 summarizes solicited injection-site reactions and systemic adverse events reported within 7 days post-vaccination via diary cards. Onset was usually within the first 3 days after vaccination and a majority of the reactions resolved within 3 days. Solicited injection-site reactions and systemic adverse events were more frequent after vaccination with Fluad compared to Fluzone.

Within 6 months post-vaccination, 156 (6.1%) Fluad recipients and 93 (7.4%) Fluzone recipients experienced a serious adverse event (SAE). No deaths were reported within 28 days post-vaccination. A total of 23 deaths were reported during Days 29 – 180 post-vaccination: 16 (0.6%) among Fluad recipients and 7 (0.6%) among Fluzone recipients. The majority of these participants had a medical history of cardiac, hepatic, neoplastic, renal, and/or respiratory diseases. These data do not provide evidence for a causal relationship between deaths and vaccination with Fluad.

Study 2 (NCT01427309, see http://clinicaltrials.gov) was a multi-center, double-blind post-licensure efficacy trial conducted in the US and Canada over two Fluad seasons. In this study, adults 65 years of age and older were randomized to receive either Fluad or Fluzone (2011-2012 and 2012-2013 formulations). The study compared the efficacy and safety of Fluad to those of Fluzone. The safety analysis set included 15,992 Fluad recipients and 15,991 Fluzone recipients.

Within the study surveillance period (approximately 6 to 8 months post-vaccination), 1323 (8.3%) Fluad recipients and 1442 (9.0%) Fluzone recipients experienced an SAE. Within 30 days post-vaccination, 204 (1.3%) Fluad recipients and 200 (1.3%) Fluzone recipients experienced an SAE. The majority of these participants had one or more chronic comorbid illnesses. A total of 167 deaths were reported within 6 to 8 months post-vaccination: 83 (0.5%) among Fluad recipients and 84 (0.5%) among Fluzone recipients. A total of 6 deaths were reported within 30 days post-vaccination: 6 (0.04%) among Fluad recipients and 0 (0 %) among Fluzone recipients. These data do not provide evidence for a causal relationship between deaths and vaccination with Fluad.

6.2 Post-Marketing Experience

The following events have been spontaneously reported during the post-approval use of Fluzone or Fluad. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure. Adverse events were included based on one or more of the following factors: severity, frequency of reporting, or strength of evidence for a causal relationship to Fluzone or Fluad.

Events Reported During Post-Approval Use of Fluzone.

11 DESCRIPTION

Fluad (Influenza Vaccine) for intramuscular injection is an inactivated Fluad vaccine, prepared from Fluad viruses propagated in embryonated chicken eggs. The virus-containing allantoic fluid is harvested and inactivated with formaldehyde. Fluad virus is concentrated and purified in a linear sucrose density gradient solution using a continuous flow centrifuge. The virus is then chemically disrupted using a non-ionic surfactant, octylphenol ethoxylate (Triton® X-100), producing a "split virus". The split virus is further purified and then suspended in sodium phosphate-buffered isotonic sodium chloride solution. The Fluad process uses an additional concentration factor after the ultrafiltration step in order to obtain a higher hemagglutinin (HA) antigen concentration.

Fluad suspension for injection is clear and slightly opalescent in color.

Neither antibiotics nor preservative are used in the manufacture of Fluad.

The Fluad prefilled syringe presentation is not made with natural rubber latex.

Fluad is standardized according to United States Public Health Service requirements and is formulated to contain HA of each of the following three Fluad strains recommended for the 2017-2018 Fluad season: A/Michigan/45/2015 X-275 (H1N1), A/Hong Kong/4801/2014 X-263-B(H3N2), and B/Brisbane/60/2008(B Victoria Lineage). The amounts of HA and other ingredients per dose of vaccine are listed in Table 2.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Fluad illness and its complications follow infection with Fluad viruses. Global surveillance of Fluad identifies yearly antigenic variants. For example, since 1977, antigenic variants of Fluad A (H1N1 and H3N2) viruses and Fluad B viruses have been in global circulation. Specific levels of hemagglutination inhibition (HI) antibody titer post-vaccination with inactivated Fluad virus vaccines have not been correlated with protection from Fluad virus infection. In some human studies, antibody titers ≥1:40 have been associated with protection from Fluad illness in up to 50% of participants.

Antibodies against one Fluad virus type or subtype confer limited or no protection against another. Furthermore, antibodies to one antigenic variant of Fluad virus might not protect against a new antigenic variant of the same type or subtype. Frequent development of antigenic variants through antigenic drift is the virologic basis for seasonal epidemics and the reason for the usual change of one or more new strains in each year's Fluad vaccine. Therefore, Fluad vaccines are standardized to contain the hemagglutinins of Fluad virus strains representing the Fluad viruses likely to be circulating in the US during the Fluad season.

Annual vaccination with the current vaccine is recommended because immunity during the year after vaccination declines and because circulating strains of Fluad virus change from year to year.

13 NON-CLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Fluad has not been evaluated for carcinogenic or mutagenic potential or for impairment of fertility.

14 CLINICAL STUDIES

14.1 Immunogenicity of Fluad in Adults 65 Years of Age and Older

Study 1 was a multi-center, double-blind pre-licensure trial conducted in the US in which adults 65 years of age and older were randomized to receive either Fluad or Fluzone (2006-2007 formulation). The study compared the safety and immunogenicity of Fluad to those of Fluzone. For immunogenicity analyses, 2576 participants were randomized to Fluad and 1275 participants were randomized to Fluzone. Females accounted for 51.3% of participants in the Fluad group and 54.7% of participants in the Fluzone group. In both groups, the mean age was 72.9 years (ranged from 65 through 97 years in the Fluad group and 65 through 94 years in the Fluzone group); 35% of participants in the Fluad group and 36% of participants in the Fluzone group were 75 years of age or older. Most participants in the Fluad and Fluzone groups, respectively, were White (91.7% and 92.9%), followed by Hispanic (4.8% and 3.7%), and Black (2.7% and 2.7%).

The primary endpoints of the study were HI GMTs and seroconversion rates 28 days after vaccination. Pre-specified statistical superiority criteria required that the lower limit (LL) of the 2-sided 95% CI of the GMT ratio (Fluzone High-Dose/Fluzone) be greater than 1.50 for at least two of the strains, and if one strain failed, non-inferiority of that strain must be demonstrated (LL>0.67), and that the lower limit of the 2-sided 95% CI of the seroconversion rate difference (Fluzone High-Dose minus Fluzone) be greater than 10% for at least two of the strains, and if one strain failed, non-inferiority of that strain must be demonstrated (LL>-10%). As shown in Table 3, statistically superior HI GMTs and seroconversion rates after vaccination with Fluad compared to Fluzone were demonstrated for Fluad A subtypes, A (H1N1) and A (H3N2), but not for Fluad type B. For strain B, non-inferiority of Fluad compared to Fluzone was demonstrated for both the HI GMTs and seroconversion rates.

Fluad Strain GMT GMT Ratio Seroconversion %Seroconversion: Paired samples with pre-vaccination HI titer <1:10 and post-vaccination (day 28) titer ≥1:40 or a minimum 4-fold increase for participants with pre-vaccination titer ≥1:10 Difference Met Both Pre-defined Superiority Criteria Predefined superiority criterion for seroconversion: the lower limit of the two-sided 95% CI of the difference of the seroconversion rates (Fluzone High-Dose minus Fluzone) is >10%. Predefined superiority criterion for the GMT ratio: the lower limit of the 95% CI of the GMT ratio (Fluzone High-Dose divided by Fluzone) is >1.5

14.2 Efficacy of Fluad in Adults 65 Years of Age and Older

Study 2 (NCT01427309) was a multi-center, double-blind post-licensure efficacy trial conducted in the US and Canada in which adults 65 years of age and older were randomized (1:1) to receive either Fluad or Fluzone. The study was conducted over two Fluad seasons (2011-2012 and 2012-2013); 53% of participants enrolled in the first year of the study were re-enrolled and re-randomized in the second year. The per-protocol analysis set for efficacy assessments included 15,892 Fluad recipients and 15,911 Fluzone recipients. The majority (67%) of participants in the per-protocol analysis set for efficacy had one or more high-risk chronic comorbid conditions.

In the per-protocol analysis set, females accounted for 57.2% of participants in the Fluad group and 56.1% of participants in the Fluzone group. In both groups, the median age was 72.2 years (range 65 through 100 years). Overall, most participants in the study were White (95%); approximately 4% of study participants were Black, and approximately 6% reported Hispanic ethnicity.

The primary endpoint of the study was the occurrence of laboratory-confirmed Fluad (as determined by culture or polymerase chain reaction) caused by any Fluad viral type/subtype in association with influenza-like illness (ILI), defined as the occurrence of at least one of the following respiratory symptoms: sore throat, cough, sputum production, wheezing, or difficulty breathing; concurrent with at least one of the following systemic signs or symptoms: temperature >99.0°F, chills, tiredness, headaches or myalgia. Participants were monitored for the occurrence of a respiratory illness by both active and passive surveillance, starting 2 weeks post-vaccination for approximately 7 months. After an episode of respiratory illness, nasopharyngeal swab samples were collected for analysis; attack rates and vaccine efficacy were calculated.
