Evaluation of the Safety and Immunogenicity of Sequential Administration of Prevnar 13™ and Pneumovax™ 23 in Healthy Participants 50 Years of Age and Older (V110-029)

The purpose of this study is to evaluate the safety and immunogenicity of sequential administration of Prevnar 13™ and Pneumovax™ 23 in healthy participants 50 years of age and older. The primary hypotheses in the study are that 1) geometric mean titers (GMTs) to pneumococcal serotypes 22F and 33F (serotypes in Pneumovax™ 23 but not in Prevnar 13™) as measured at Week 12 are superior in participants administered Prevnar 13™ on Day 1 and Pneumovax™ 23 at Week 8, as compared with participants administered Prevnar 13™ on Day 1 and placebo at Week 8 and 2) GMTs to pneumococcal serotypes shared by the two vaccines as measured at Week 12 are non-inferior in participants administered Prevnar 13™ followed by Pneumovax™ 23 as compared with participants administered Prevnar 13™ followed by placebo.

Pneumococcal vaccine containing serotypes 1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20, 22F, 23F, and 33F. Injections are to be administered into the deltoid muscle of the upper arm.

Placebo

Biological

Injections are to be administered into the deltoid muscle of the upper arm.

Primary outcomes

  1. Percentage of Participants With an Adverse Event (AE)

    Time frame: Up to 14 days after any vaccination (Up to 28 weeks)

    An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

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

    Time frame: Up to 14 days after any vaccination (Up to 28 weeks)

    An injection site adverse event (AE) includes the following AEs at the injection site: redness, swelling, and pain/tenderness.

  3. Percentage of Participants With a Systemic Adverse Event

    Time frame: Up to 14 days after any vaccination (Up to 28 weeks)

    Systemic adverse events (AEs) include, but are not restricted to the following AE terms: muscle pain, joint pain, headache, and tiredness.

  4. Percentage of Participants With a Serious Adverse Event (SAE)

    Time frame: Up to 30 weeks

    A serious adverse event (SAE) is any adverse event occurring at any dose or during any use of Sponsor's product that: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is another important medical event; is a cancer; or is associated with an overdose.

  5. Percentage of Participants With a Vaccine-related Serious Adverse Event (SAE) or Vaccine-related Death

    Time frame: Up to 30 weeks

    A serious adverse event (SAE) is any adverse event occurring at any dose or during any use of Sponsor's product that: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is another important medical event; is a cancer; or is associated with an overdose. The investigator determined whether the SAE or death was related to vaccine treatment.

  6. Percentage of Participants Who Discontinued Vaccination Due to an Adverse Event

    Time frame: Up to 26 weeks

    An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

  7. Geometric Mean Titers to Pneumococcal Serotypes 22F and 33F at Week 12

    Time frame: Week 12

    Vaccine-induced functional antibodies to serotypes 22F and 33F, which are unique to PNEUMOVAX™ 23, were measured by the multiplex opsonophagocytic activity 4 (MOPA-4) assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

  8. Geometric Mean Titers to Pneumococcal Serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, at Week 12

    Time frame: Week 12

    Vaccine-induced functional antibodies to serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, which are contained in both Prevnar 13™ and PNEUMOVAX™ 23, were measured by the MOPA-4 assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

Secondary outcomes

  1. Geometric Mean Titers to Pneumococcal Serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F, and 33F at Week 8

    Time frame: Week 8

    Vaccine-induced functional antibodies were measured by the MOPA-4 assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

  2. Geometric Mean Titers to Pneumococcal Serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F, and 33F at Week 26

    Time frame: Week 26

    Vaccine-induced functional antibodies were measured by the MOPA-4 assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.

  3. Geometric Mean Titers to Pneumococcal Serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F, and 33F at Week 30

    Time frame: Week 30

    Vaccine-induced functional antibodies were measured by the MOPA-4 assay, which is based on the ability of antibody in the serum to initiate killing of bacterial pneumococci.
