Trial overview

Official title: Observer-blind immunogenicity study of GSK Biologicals’ influenza vaccine GSK2186877A in elderly subjects
Trial description: This clinical trial aims to study the immunogenicity of GSK Biologicals’ influenza vaccine GSK2186877A in people aged 65 years or older.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Triple (Participant, Investigator, Outcomes Assessor)
Allocation:
Randomized
Primary outcomes:

The Geometric Mean (GM) number of influenza-specific CD4 T-cells per million CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains which are producing at least two different markers

Timeframe: Day 21

Secondary outcomes:

The GM number of influenza-specific CD4 T-cells per million CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains and with each vaccine strain separately which were producing at least two different markers

Timeframe: At Day 0, 21, 42 and 180

The GM number of influenza-specific CD4 T-cells per million CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains and with each vaccine strain separately producing each of the immune markers plus another immune marker

Timeframe: At Day 0, 21, 42 and 180

Haemagglutinin inhibition (HI) antibody titers

Timeframe: At Day 0, 21, 42 and 180

The number of subjects seropositive to HI antibodies calculated after in vitro stimulation with separate vaccine strains.

Timeframe: At Day 0, 21, 42 and 180

  • All subjects must satisfy the following criteria at study entry:
  • Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study. Specific attention should be given to the compliance potential of subjects with suspected or known drug or alcohol abuse.
  • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days prior to vaccination, or planned use during the study period.
  • Administration of other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to enrolment in this study. Planned administration of a vaccine not foreseen by the study protocol up to Visit 4 after vaccination and of an influenza vaccine other than the study vaccines up to Visit 4.
