Trial overview
Official title: A Study to Evaluate the Safety, Reactogenicity & Immunogenicity of the GSK Biologicals Candidate Pneumococcal Vaccine Without or With Adjuvant, Administered at 2 Different Concentrations, in Healthy Elderly Subjects
Trial description: As the licensed Pneumovax 23™ vaccine is not always satisfactory in elderly subjects, the safety and the immune response of the new investigational pneumococcal protein vaccine is evaluated in healthy elderly population.
Primary purpose:
Prevention
Trial design:
Parallel Assignment
Masking:
Single (Participant)
Allocation:
Randomized
Primary outcomes:
Occurrence, intensity and relationship of any solicited local and general signs and symptoms.
Timeframe: During a 7-day follow up period after each vaccine dose.
Occurrence, intensity and relationship to vaccination of unsolicited local and general signs and symptoms.
Timeframe: During a 30-day follow up period after each vaccine dose.
Occurrence of all serious adverse events (SAE).
Timeframe: During the entire study period.
Anti- PhtD antibody concentration
Timeframe: One month after the first injection
Anti-PhtD antibody concentration.
Timeframe: One month after 2 injections
Secondary outcomes:
Number and percentage of subjects with normal or abnormal values for biochemical assessments and for haematological analysis.
Timeframe: At each scheduled time point (month 0, 1, 3, 12, 24 and 36).
Anti- PhtD antibody concentration.
Timeframe: At 12, 24 and 36 months after the first vaccination.
Anti-PhtD antibody avidity.
Timeframe: At month 0, 1 and 3.
Evaluation of protection afforded by passive transfer of anti PhtD antibodies sera pooled from all individuals.
Timeframe: At month 0, 1 and 3.
Frequency of PhtD specific plasma cells generated by in vitro cultivated memory B-cells, in a subset of subjects.
Timeframe: At month 0, 1, 3, 12.
Frequency of CD4 and/or CD8 T cells that produce cytokines (IL-2, IL-4, IFNg, CD40L and/or GM-CSF, and TNFα), upon PhtD re-stimulation in vitro, to evaluate the T-cell response, in a subset of subjects.
Timeframe: At month 0, 1, 3, 12.
Anti-polysaccharide total IgG concentration in Group A for all vaccine pneumococcal serotypes
Timeframe: At month 0, 1, 12, 24 and 36.
Anti-PS antibody avidity for 5 serotypes in Group A.
Timeframe: At month 0 and 1.
Deposition of complement components on the surface of different bacterial strains 3 strains (GSK/CDC, OPA, isogenic TIGR4) of 5 serotypes in Group A.
Timeframe: At month 0 and 1.
Opsonophagocytic activity titres in Group A to all vaccine pneumococcal serotypes
Timeframe: At month 0, 1 and 12.
Frequency of PS-specific plasma cells generated by in vitro cultivated memory B-cells in Group A in a subset of subjects.
Timeframe: At month 0 and month 1.
