Trial to Evaluate the Efficacy of GSK Biologicals' Influenza Vaccine GSK2186877A in Adults 65 Year of Age and Older

Occurrence of PCR-confirmed influenza A and/or B infection, due to any matching or drift influenza strain relative to the vaccine strains (i.e. not emerging novel human influenza strain like H1N1v). PCR-confirmed influenza (PCI) was defined as an episode of influenza-like illness (ILI) occurring after the administration of the study vaccine for which a nasal and throat swab specimen yields influenza virus A and/or B by reverse transcription polymerase chain reaction (RT-PCR) analysis.

Vaccine strains assessed were A/Brisbane/59/2077, A/Uruguay/716/2007 and B/Brisbane/3/2007. Titers were expressed as geometric mean titers calculated on all subjects in the lot-to-lot subset of subjects.

Occurrence of culture-confirmed influenza A and/or B infection, due to any matching or drift influenza strain relative to the vaccine strains (i.e. not emerging novel human influenza strain like H1N1v). Culture-confirmed influenza (CCI) was defined as an episode of ILI occurring after the administration of the study vaccine for which a nasal and throat swab specimen yields influenza virus A and/or B by viral culture analysis.

Clinical influenza= An ILI episode (with an ILI onset from the 15th of November until the end of the surveillance period) with at least simultaneously fever (oral temperature of ≥37.8 degrees Celsius) and cough.

The influenza peak season = period during the study with the highest incidence of any matching or drift influenza strain relative to the vaccine strains (i.e. not emerging novel human influenza strain like H1N1v).

Respiratory disease: A diagnosis of respiratory disease included: acute respiratory infections, other diseases of upper respiratory tract, pneumonia and influenza, chronic obstructive pulmonary disease and allied conditions, pneumoconioses and other lung diseases due to external agents, other diseases of respiratory system. In case the event has a fatal outcome, the diagnosis can also be confirmed by autopsy.

Adverse events of specific interest for safety monitoring are a subset of AEs that included both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology.

Grade 3 = event that prevented normal everyday activities Related = event assessed by the investigator as causally related to the study vaccination

Grade 3 = event that prevented normal everyday activities Related = event assessed by the investigator as causally related to the study vaccination

SAEs assessed include medical occurrences that results in death, are life threatening, require hospitalization or prolongation of hospitalization, results in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subjects.

Related = event assessed by the investigator as causally related to the study vaccination

Solicited local symptoms assessed were ecchymosis, pain, redness and swelling. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = considerable pain at rest that prevented normal everyday activities. Grade 3 ecchymosis/redness/swelling = ecchymosis/redness/swelling above 100 millimeter

Solicited local symptoms assessed were ecchymosis, pain, redness and swelling.

Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal, headache, myalgia, shivering and temperature (defined as oral temperature equal to or above (≥) 38.0 degrees Celsius). Any = incidence of a particular symptom regardless of intensity grade or relationship to vaccination. Grade 3 = general symptom which prevented normal everyday activities. Related = general symptom assessed by the investigator as causally related to the study vaccination. Grade 3 temperature = oral temperature ≥39.0°C - ≤ 40.0°C.

An unsolicited adverse event is any adverse event (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Grade 3 = event that prevented normal, everyday activities. Related = event assessed by the investigator as causally related to the study vaccination.

Grade 3 = event that prevented normal, everyday activities. Related = event assessed by the investigator as causally related to the study vaccination.

For each solicited and unsolicited symptom the subject experienced, the subjects were asked if they received medical attention defined as hospitalisation, an emergency room visit or a visit to or from medical personnel (medical doctor) for any reason.

In the lot-to-lot subset of subject in the FluGN Group. Vaccine strains assessed were A/Brisbane/59/2077, A/Uruguay/716/2007 and B/Brisbane/3/2007. Seroconversion is defined as the number of subjects with pre-vaccination HI titer (Day 0) < 1:10 and post-vaccination titer (Day 21) ≥ 1:40 or a pre-vaccination HI titer (Day 0) ≥ 1:10 and fold-increase (post/pre) ≥ 4.
