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

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

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).

Single 0.5 milliliter (mL) 13-valent pneumococcal conjugate vaccine (13vPnC) and a single 0.5 mL trivalent inactivated influenza vaccine (TIV), administered intramuscularly (IM), followed by a single 0.5 mL vaccine 13vPnC placebo, 1 month later.

Single 0.5 mL 13vPnC placebo vaccine and a single 0.5 mL TIV, administered IM, followed by a single 0.5 mL 13vPnC vaccine, 1 month later.

TIV Comparisons: Percentage of Participants Achieving at Least a 4-fold Increase in the Titer of the Standard Hemagglutination Inhibition Assay (HAI)

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.

13vPnC Comparisons: Serotype-specific Pneumococcal Immunoglobulin G (IgG) Geometric Mean Concentration (GMC)

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.

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).

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.

Inclusion Criteria: Generally healthy male or female adults 65 years of age or older. Available for the duration of the trial - approximately 2 months. No previous vaccination with any pneumococcal vaccine. No history of severe adverse reaction associated with a vaccine. No allergy to egg proteins (eggs or egg products) and chicken proteins.
