Study Evaluating Safety and Immunogenicity of 13-Valent Pneumococcal Conjugate Vaccine With Influenza Vaccine in Adults

January 17, 2012 updated by: Pfizer

A Phase 3, Randomized, Double-blind Trial to Evaluate Safety, Tolerability, and Immunogenicity of a 13-Valent Pneumococcal Conjugate Vaccine When Administered Concomitantly With Trivalent Inactivated Influenza Vaccine in Healthy Adults 65 Years of Age or Older, Who Are Naive to 23-Valent Pneumococcal Polysaccharide Vaccine

The 13-valent pneumococcal conjugate vaccine (13vPnC) is being developed for adults to prevent pneumococcal diseases such as meningitis (inflammation of the brain lining), septicemia (blood poisoning), and pneumonia (inflammation of the lungs). As trivalent influenza vaccine (TIV) is frequently given to adults, it is important to show that both vaccines can safely be given together without affecting the immune response (body's ability to protect against disease).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
TIV Comparisons: Percentage of Participants Achieving at Least a 4-fold Increase in the Titer of the Standard Hemagglutination Inhibition Assay (HAI)
Time Frame: Baseline and 1 month after TIV vaccination
Percentage of participants achieving at least a 4-fold increase in the titer of the standard HAI for each influenza virus subtype (A/H1N1, A/H3N2, and B) were compared.
Baseline and 1 month after TIV vaccination
13vPnC Comparisons: Serotype-specific Pneumococcal Immunoglobulin G (IgG) Geometric Mean Concentration (GMC)
Time Frame: 1 month after 13vPnC vaccination
IgG GMC as measured by enzyme-linked immunosorbent assay (ELISA) and expressed in micrograms per mL (mcg/mL) for serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F.
1 month after 13vPnC vaccination

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Pre-specified Local Reactions
Time Frame: Days 1 through 14 after 13vPnC vaccination
Local reactions were reported using an electronic diary. Pain was scaled as Any; Mild (awareness but easily tolerated); Moderate (discomfort enough to interfere with usual activity) and Severe (incapacitating the usual activity). Redness and swelling were scaled as Any; Mild (2.5 cm to 5.0 cm); Moderate (5.1 to 10.0 cm)and Severe (> 10.0 cm). Limitation in arm movement were scaled as Any; Mild (some limitation); Moderate (unable to move above head but able to move above shoulder) and Severe (unable to move above shoulder).
Days 1 through 14 after 13vPnC vaccination
Percentage of Participants With Pre-specified Systemic Events
Time Frame: Days 1 through 14 after 13vPnC vaccination
Systemic events (Any fever >= 38 degrees Celsius [C]), fatigue, headache, chills, rash, vomiting, decreased appetite, new muscle pain, any aggravated muscle pain, new joint pain or any aggravated joint pain. Participants may be presented in more than one category.
Days 1 through 14 after 13vPnC vaccination
