Study Evaluating Antibody Response Of 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) 24 Months After Toddler Dose.

January 5, 2012 updated by: Pfizer

A Phase 3, Open-label Study to Evaluate Persistence of the Antibody Response Elicited by Pneumococcal Conjugate Vaccine in Healthy Children Who Have Been Previously Immunized With a 4-Dose Series of a Pneumococcal Conjugate Vaccine During Infancy in Study 6096A1-008-EU and the Safety and Immunogenicity of 13-valent Pneumococcal Conjugate Vaccine Administered at Least 24 Months After the Last Toddler Dose of Pneumococcal Conjugate Vaccine

This is an open-label study (a study in which the doctors and participants know which drug or vaccine is being administered) in children who previously received a 4-dose series of a pneumococcal conjugate vaccine (PnC) during infancy in Study 6096A1-008-EU (NCT00366678). In this study, participants will receive an additional dose of 13-valent pneumococcal conjugate vaccine. The purpose of this study is to evaluate persistence, if any, of the antibody response by measuring any remaining pneumococcal antibodies since the previous study. This study will also evaluate the safety and immunogenicity of 13-valent pneumococcal conjugate vaccine when administered at least 24 months after the last dose of pneumococcal conjugate vaccine.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Serotype-specific Pneumococcal Immunoglobulin G (IgG) Geometric Mean Concentration (GMC) 1 Month After Single Dose of 13 Valent Pneumococcal Conjugate (13vPnC) Vaccine
Time Frame: One month after vaccination
Antibody GMC as measured by microgram/millilitre (mcg/mL) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented. GMC (13vPnC) and corresponding 2-sided 95% confidence intervals (CI) were evaluated. Geometric means (GMs) were calculated using all participants with available data for the specified blood draw.
One month after vaccination
Percentage of Participants With Prespecified Local Reactions
Time Frame: Seven days after vaccination
Local reactions (redness, swelling and pain) were reported using electronic diary. Redness and swelling were recorded in caliper units (range 1 to 14+), each caliper unit represented 0.5 cm. Categorized as any, absent (no redness or swelling present; 0 caliper units), mild (0.5 to 2.0 cm; 1 to 4 caliper units); moderate (2.5 to 7.0 cm; 5 to 14 caliper units); or severe (>7.0 cm; >14 caliper units). Pain was categorized as any, mild: does not interfere with activity; moderate: interferes with activity; severe: prevents daily activity. Participants may be reported in more than 1 category.
Seven days after vaccination
Percentage of Participants With Prespecified Systemic Events
Time Frame: Seven days after vaccination
Systemic events (any fever >= 38 degree celsius [C], vomiting, diarrhea, and fatigue) were reported using electronic diary. Fever categorized as >=38 to <=39 degree C; >39 to <=40 degree C; >40 degree C. Vomiting: mild (1-2 times/day ); moderate (>2 times/day); severe (requires intravenous hydration). Diarrhea: mild (2-3 loose stools/day); moderate (4-5 stools/day); severe (>=6 loose stools/day). Fatigue: mild (does not interfere with activity); moderate (some interference with activity); severe (prevents daily routine activity). Participants may be reported in more than 1 category.
Seven days after vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Serotype-specific Pneumococcal IgG GMC Prior to Single Dose of 13vPnC Vaccine
Time Frame: Up to 7 days before vaccination
IgG GMC to the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were determined in the blood samples of all the participants using a standardized anti-pneumococcal IgG enzymelinked immunosorbent assay (ELISA). CIs for GMC are back transformations of a CI based on the Student t distribution for the mean logarithm of the concentrations.
Up to 7 days before vaccination
Serotype-specific Pneumococcal IgG GMC at 4 to 7 Days After the Single Dose of 13vPnC Vaccine
Time Frame: Four to seven days after vaccination

Time Frame: Up to 7 days before vaccination
Pneumococcal OPA GMTs for 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were determined in the blood samples of all the participants using a microcolony OPA (mcOPA) assay. CIs for GMT are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers.
Up to 7 days before vaccination
Serotype-specific OPA GMTs 1 Month After Single Dose of 13vPnC Vaccine
Time Frame: One month after vaccination
Serotype-specific pneumococcal OPA GMTs for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were determined in the blood samples of all the participants using mcOPA assay. CIs for GMT are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers.
One month after vaccination
Percentage of Participants With at Least 1/8 Serotype-specific OPA GMTs After Single Dose of 13vPnC Vaccine
Time Frame: One month after vaccination
Percentage of participants with at least 1/8 serotype-specific pneumococcal OPA GMTs for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) determined in the blood samples of all participants.
One month after vaccination
