Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted
Proper Name: Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted
Trade Name: None
Naming Convention: Q(Quebec-manufactured) + Pan (pandemic vaccine) + subtype = “Q-Pan H5N1” This discussion: Assume that the full dose of the
adjuvant (AS03A) is added unless otherwise noted.

Q-Pan-H5N1
An inactivated, split virion A/H5N1 influenza virus antigen mixed with AS03
AS03: an oil-in-water emulsion adjuvant containing:
Squalene - an unsaturated, metabolizable oil extracted from shark liver
D,L-Alpha-tocopherol (Vitamin E) Polysorbate 80
Thought to enhance both innate and adaptive immune responses by enhancing delivery of antigen to antigen presenting cells.

Q-Pan H5N1
GSK’s Proposed Indication: Influenza A (H5N1) Virus Monovalent
Vaccine, Adjuvanted is a vaccine indicated for active immunization for the prevention of disease in persons 18 years of age and older at increased risk of exposure to influenza A virus H5N1 subtype contained in the vaccine.

Q-Pan H5N1
Proposed Dosage: 3.75μg H5N1 HA + AS03 Antigen dose assessed in Study D-Pan-H5N1-007
Dresden manufactured pandemic vaccine (D-Pan) A/Vietnam H5N1 strain Hemagglutinin-inhibiting (HI) antibody responses were
Assessed across doses: 3.75 μg, 7.5 μg,15 μg and 30μg H5N1 HA with and without AS03A
HI antibody responses were low across all doses without AS03A adjuvant
antigen dose-dependent fashion HI antibody responses were high independent of the antigen
dose with AS03A adjuvant

These criteria and the 1:40 HI antibody titer are borrowed from seasonal influenza.
Historical data suggest that at a titer of 1:40 ~50% of subjects may be protected from illness due to seasonal influenza virus.

Arepanrix (1.9 μg H1N1+AS03B) Effectiveness Study
Limitations of the study Small sample size Large percentage of subjects excluded from the
effectiveness analysis Potential for bias e.g. selection, reporting Retrospective study design
Conclusions: Study suggests a single, 0.25mL dose of Arepanrix
H1N1 was effective against H1N1 influenza virus in this small, study in children
Given limitations, CBER is unable to use the results of this study to confirm effectiveness of Q-Pan H5N1

ISS-1 Results Solicited adverse events were reported similarly to
events in the pivotal clinical trials Frequency and severity
Mild temperature elevations occurred twice as frequently in H5N1+AS03 subjects vs control subjects.
H5N1+AS03 subjects reported more unsolicited injection site reaction, injection site warmth, injection site
pruritus, malaise, nausea, insomnia and dizziness All reported pIMDs were in the H5N1+AS03 arm (n=17)

Summary of Pandemrix and Arepanrix Post Marketing Safety Analyses
GSK conducted specific analyses to assess postmarketing safety of Pandemrix and Arepanrix for a number of safety outcomes: Thrombocytopenia, anaphylaxis, arthropathies, pain
in extremity, convulsions, dysgeusia/ageusia, facial palsy/paresis, Guillain-Barré Syndrome (GBS), narcolepsy, pregnancy outcomes, stillbirth, safety data from pediatric subjects, solid organ transplant rejection, events with fatal outcomes

Summary of Arepanrix and Pandemrix H1N1
Post Marketing Safety Analyses Results Febrile convulsion – Arepanrix H1N1
Most common SAE reported after Arepanrix vaccination in children 0 – 2 years of age (event rate of 1/1 million vaccinated) 3 – 9 years of age (event rate of 0.5/1 million vaccinated)
Febrile convulsion was added to the Arepanrix H1N1 Reference Safety Information (RSI).
Guillain-Barré Syndrome (GBS) – Arepanrix H1N1 Observed number of cases > expected number of
cases (from literature and Arepanrix exposure data) Guillain-Barré syndrome was relocated in the RSI to
be listed as “reported with Arepanrix H1N1”.

Narcolepsy and Pandemrix H1N1
Increased postmarketing reports of narcolepsy post Pandemrix H1N1 vaccination Studies in Finland, Sweden and Ireland identified
6-13 fold increased risk of narcolepsy in children and adolescents post vaccination
3 - 7 excess cases/100,000 vaccinated
Added to the “Warnings” and “Undesirable Effects” of the Pandemrix EU Summary of Product Characteristics Restricted its use in persons < 20 years old

Narcolepsy: General Information A disorder of sleep-wake control in which elements of
sleep intrude into wakefulness and elements of wakefulness intrude into sleep. Sleep maintenance insomnia is common Narcoleptics can be misdiagnosed as insomniacs
Manifests as daytime sleepiness with or without cataplexy – emotionally triggered, transient muscle weakness hypnagogic hallucinations sleep paralysis
Narcolepsy with cataplexy Estimated prevalence in the U.S. 25-50/100,000 persons1
Estimated incidence in the U.S. 0.74/100,000 person-years1
Typically diagnosed in teens and early twenties Narcolepsy may be triggered by immune activation and
has a strong HLA association (DQB1*0602)1

Pharmacovigilance Plan
Passive surveillance (pre-pandemic and pandemic period) Routine data collection on all adverse event reports Global literature review, periodic distribution and
safety reports Disproportionality analysis (signal detection) –
monthly (pre-pandemic), weekly (pandemic) Close monitoring of the following AEs: Bell's palsy,
convulsion, demyelinating disorders, encephalitis, Guillain-Barré syndrome (GBS), neuritis, vasculitis, vaccination failure, narcolepsy, AIH and increased concentrations of transaminases.

Pharmacovigilance Plan

country Data will be shared with U.S.
Pregnancy registry GSK has committed to working with the US
government to evaluate safety.

Q-Pan H5N1 Summary Slide Proportion of subjects achieving seroconversion
and HI titers > 1:40 after 2 doses of Q-Pan-H5N1, 21 days apart Exceeds CBER’s suggested immunogenicity criteria
for accelerated approval of a pandemic vaccine. Significant local and systemic reactogenicity
Pain was the most frequent solicited event Transient, not requiring medical attention
Imbalance in reporting frequency of unsolicited AEs, SAEs, and AESI/pIMDs Significance of these imbalances are unclear due to
Rarity of events both in the studies and in the general population.
Size of the study populations

85
Discussion Topic for the Committee
Please discuss the following two approaches to confirm the effectiveness of Q-Pan H5N1 for “traditional” approval.
1. To confirm the clinical benefit of Q-Pan H5N1 with efficacy data generated with a US-licensed seasonal influenza virus vaccine made according to the same manufacturing process.
2. To confirm the clinical benefit of Q-Pan H5N1 by conducting an effectiveness study (or studies) during an H5N1 influenza virus pandemic.
