Safety and Efficacy Study of Investigational Pneumococcal Vaccine in Elderly Population

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.

About this study

Since influenza vaccination is recommended in the age range of the study population, Fluarix™ (GlaxoSmithKline Biologicals) vaccine will be offered free of charge during the study period (for 3 consecutive years starting from September 2004), to be used by Investigators according to national vaccination schedule/practice.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subjects who the investigator believes will comply with the requirements of the protocol
  • A male or female ≥ 65 years at the time of the first vaccination.
  • Written informed consent obtained from the subject.
  • Free of obvious health problems as established by medical history and clinical examination before entering into the study.

Exclusion criteria

  • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period or participation to another pharmaceutical/vaccine study.
  • Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
  • Use of any anticoagulants.
  • Planned administration/ administration of a vaccine not foreseen by the study protocol within 2 weeks of the first dose of vaccines.
  • Previous vaccination against Streptococcus pneumoniae.
  • Bacterial pneumonia within 3 years prior to 1st vaccination.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection.
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
  • Current serious neurologic or mental disorders.
  • Currently smoking > 25 cigarettes per day.
  • Inflammatory processes such as known chronic active infections
  • All malignancies (excluding non-melanic skin cancer) and lymphoproliferative disorders diagnosed or treated actively during the past 5 years.
  • History of administration of an experimental vaccine containing MPL or QS21.
  • Acute disease at the time of enrolment.
  • Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests, at the discretion of the investigator.
  • History of chronic alcohol consumption and/or intravenous drug abuse.

Treatment and study plan

Pneumococcal vaccine GSK513026

Biological

Two-dose intramuscular injection. Five different formulations, each administered to one Group

Pneumovax 23™

Biological

Single dose intramuscular injection.

Primary outcomes

  1. Occurrence, intensity and relationship of any solicited local and general signs and symptoms.

    Time frame: During a 7-day follow up period after each vaccine dose.

  2. Occurrence, intensity and relationship to vaccination of unsolicited local and general signs and symptoms.

    Time frame: During a 30-day follow up period after each vaccine dose.

  3. Occurrence of all serious adverse events (SAE).

    Time frame: During the entire study period.

  4. Anti- PhtD antibody concentration

    Time frame: One month after the first injection

  5. Anti-PhtD antibody concentration.

    Time frame: One month after 2 injections

Secondary outcomes

  1. Number and percentage of subjects with normal or abnormal values for biochemical assessments and for haematological analysis.

    Time frame: At each scheduled time point (month 0, 1, 3, 12, 24 and 36).

  2. Anti- PhtD antibody concentration.

    Time frame: At 12, 24 and 36 months after the first vaccination.

  3. Anti-PhtD antibody avidity.

    Time frame: At month 0, 1 and 3.

  4. Evaluation of protection afforded by passive transfer of anti PhtD antibodies sera pooled from all individuals.

    Time frame: At month 0, 1 and 3.

  5. Frequency of PhtD specific plasma cells generated by in vitro cultivated memory B-cells, in a subset of subjects.

    Time frame: At month 0, 1, 3, 12.

  6. 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.

    Time frame: At month 0, 1, 3, 12.

  7. Anti-polysaccharide total IgG concentration in Group A for all vaccine pneumococcal serotypes

    Time frame: At month 0, 1, 12, 24 and 36.

  8. Anti-PS antibody avidity for 5 serotypes in Group A.

    Time frame: At month 0 and 1.

  9. Deposition of complement components on the surface of different bacterial strains 3 strains (GSK/CDC, OPA, isogenic TIGR4) of 5 serotypes in Group A.

    Time frame: At month 0 and 1.

  10. Opsonophagocytic activity titres in Group A to all vaccine pneumococcal serotypes

    Time frame: At month 0, 1 and 12.

  11. Frequency of PS-specific plasma cells generated by in vitro cultivated memory B-cells in Group A in a subset of subjects.

    Time frame: At month 0 and month 1.
