NCT ID: NCT00652951

Last Updated: 2019-06-26

Results Overview

Anti-pneumococcal serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F antibody concentrations (Anti-1, -4, -5, -6B, -7F, -9V, -14, -18C, -19F and -23F) were measured by 22F-inhibition Enzyme-Linked ImmunSorbent Assay (ELISA); presented as geometric mean concentrations (GMCs) and expressed in micrograms per milliliter (μg/mL). The seropositivity cut-off for the assay was greater than or equal to (≥) 0.05 μg/mL.

Participant Flow

The study included a Primary (PRI) Phase, up to Month 3, followed by a Booster (BST) Phase, up to Month 9.

At screening the following was performed: informed consent was obtained and signed from subjects' parents/guardians, check for inclusion/exclusion criteria and contraindications/precautions was performed as regards to vaccination, and medical history of subjects was collected. Subjects' pre-vaccination body temperature was evaluated.

Timeframe: At Month 3, one month after the administration of the third dose of pneumococcal conjugate vaccine

Population: The Primary ATP cohort for immunogenicity included all evaluable subjects for whom data concerning immunogenicity outcome measures were available. This included subjects for whom assay results were available for antibodies against at least one study vaccine antigen component post-dose III.

Population: The Primary ATP cohort for immunogenicity included all evaluable subjects for whom data concerning immunogenicity outcome measures were available. This included subjects for whom assay results were available for antibodies against at least one study vaccine antigen component post-dose III.

Anti-PD antibody concentrations were presented as geometric mean concentrations (GMCs) and expressed in ELISA units per milliliter (EL.U/mL). The seropositivity cut-off for the assay was ≥ 100 EL.U/mL.

Population: The Primary ATP cohort for immunogenicity included all evaluable subjects for whom data concerning immunogenicity outcome measures were available. This included subjects for whom assay results were available for antibodies against at least one study vaccine antigen component post-dose III.

Antibody concentrations were presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL). A seroprotected subject was a subject whose antibody ChemiLuminescence ImmunoAssay (CLIA) concentration was greater than or equal to the cut-off value ≥ 10 milli-international units per milliliter (mIU/mL). Note: investigations on the quality of some serology assays revealed that the anti-HBs ELISA overestimated concentration between 10-100 mIU/mL while values \> 100 mIU/mL were confirmed valid. Therefore, all available samples at one month post-dose III and one month post-dose IV timepoints for which the anti-HBs antibody concentration was between 10-100 mIU/mL by in-house ELISA, were retested by the commercial assay Centaur™, an FDA-approved and CE-marked CLIA with a cut-off defining seropositivity of 6.2 mIU/mL. Anti-HBs seroprotection was redefined as in-house ELISA concentration \> 100 mIU/mL or CLIA concentration \> 10 mIU/mL.

Antibody concentrations were presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL). A seroprotected subject was a subject whose antibody ChemiLuminescence ImmunoAssay (CLIA) concentration was greater than or equal to the cut-off value ≥ 10 milli-international units per milliliter (mIU/mL). Note: investigations on the quality of some serology assays revealed that the anti-HBs ELISA overestimated concentration between 10-100 mIU/mL while values \> 100 mIU/mL were confirmed valid. Therefore, all available samples at one month post-dose III and one month post-dose IV timepoints for which the anti-HBs antibody concentration was between 10-100 mIU/mL by in-house ELISA, were retested by the commercial assay Centaur™, an FDA-approved and CE-marked CLIA with a cut-off defining seropositivity of 6.2 mIU/mL. Anti-HBs seroprotection was redefined as in-house ELISA concentration \> 100 mIU/mL or CLIA concentration \> 10 mIU/mL.

Timeframe: During the 4-day (Days 0-3) post-vaccination period following each dose and across doses

Population: The Primary Total Vaccinated cohort included all vaccinated subjects who received at least one primary dose.

Solicited local symptoms assessed were pain, redness and swelling. Any was defined as any occurrence of the specified symptom regardless of intensity. Grade 3 pain was defined as cried when limb was moved/spontaneously painful. Grade 3 redness/swelling was defined as redness/swelling spreading beyond (\>) 30 millimeters from injection site.

SECONDARY outcome

Timeframe: Within the 31-day (Days 0-30) post-primary vaccination

Population: The Primary Total Vaccinated cohort included all vaccinated subjects who received at least one primary dose.

An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. "Any" is defined an incidence of an unsolicited AE regardless of intensity or relationship to study vaccination.
