About this study

Official title: A Study Evaluating the Safety and Immunogenicity of Revaccination With 23-Valent Pneumococcal Polysaccharide Vaccine in Older Japanese Adults

The purpose of this study is to determine if revaccination with pneumococcal vaccine (PNEUMOVAX™ 23, V110) is well tolerated and produces an immune response in older Japanese adults. The primary hypothesis being tested is that the geometric mean concentration of antibodies to pneumococcal polysaccharide serotypes 3, 6B, and 23F at 4 weeks after revaccination will be superior to that before revaccination in Japanese adults who received a primary vaccination at least 5 years before revaccination.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Serotype-Specific Antibody Geometric Mean Concentration at 4 Weeks After Revaccination

    Serum antibodies to pneumococcal serotypes were measured by enzyme-linked immunosorbent assays. Geometric mean antibody concentrations (GMCs) were calculated at Baseline and 4 weeks postvaccination. Geometric Mean Fold Rise was the GMC at 4 weeks after vaccination minus the GMC at Baseline.

    Measured: Baseline and 4 weeks after revaccination

Secondary outcomes (9)
  1. Change From Baseline in Serotype-Specific Antibody Geometric Mean Concentration at 4 Weeks After Primary Vaccination

    Serum antibodies to pneumococcal serotypes were measured by enzyme-linked immunosorbent assays. Geometric mean antibody concentrations (GMCs) were calculated at Baseline and 4 weeks postvaccination. Geometric Mean Fold Rise was the GMC at 4 weeks after vaccination minus the GMC at Baseline.

    Measured: Baseline and 4 weeks after primary vaccination

  2. Percentage of Participants With an Adverse Event of Injection-site Erythema

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of injection-site erythema recorded on the Vaccine Report Card (VRC) during the first 5 days after vaccination was recorded.

    Measured: Up to 5 days after vaccination

  3. Percentage of Participants With an Adverse Event of Injection-site Swelling

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of injection-site swelling recorded on the VRC during the first 5 days after vaccination was recorded.

    Measured: Up to 5 days after vaccination

  4. Percentage of Participants With an Adverse Event of Injection-site Pain

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of injection-site pain recorded on the VRC during the first 5 days after vaccination was recorded.

    Measured: Up to 5 days after vaccination

  5. Percentage of Participants With an Adverse Event of Pyrexia

    Percentage of participants with an adverse event of pyrexia (>=37.5°C, oral) recorded on the VRC during the first 5 days after vaccination was recorded.

    Measured: Up to 5 days after vaccination

  6. Percentage of Participants With an Adverse Event of Myalgia

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of myalgia recorded on the VRC during the first 14 days after vaccination was recorded.

    Measured: Up to 14 days after vaccination

  7. Percentage of Participants With an Adverse Event of Arthralgia

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of arthralgia recorded on the VRC during the first 14 days after vaccination was recorded.

    Measured: Up to 14 days after vaccination

  8. Percentage of Participants With an Adverse Event of Headache

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of headache recorded on the VRC during the first 14 days after vaccination was recorded.

    Measured: Up to 14 days after vaccination

  9. Percentage of Participants With an Adverse Event of Fatigue

    An adverse event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to this medicinal product. Percentage of participants with an adverse event of fatigue recorded on the VRC during the first 14 days after vaccination was recorded.

    Measured: Up to 14 days after vaccination
