About this study
Official title: A Phase 3, Randomized, Active-controlled, Double-blind Trial Evaluating The Safety, Tolerability, And Immunogenicity Of A 13-valent Pneumococcal Conjugate Vaccine Given With Dtap Compared To Open-label Dtap In Healthy Japanese Infants
Subjects will be randomly assigned to 1 of 3 groups to receive the following vaccines: Group 1: 13-valent pneumococcal conjugate vaccine (13vPnC) and diphtheria, tetanus, and acellular pertussis vaccine (DTaP), Group 2: 7-valent pneumococcal conjugate vaccine (7vPnC) and DTaP, Group 3: DTaP alone. Group 3 subjects will also receive catch-up doses of Prevenar (commercial product of Prevenar in Japan) 13vPnC and 7vPnC will be blinded, and DTaP will be open-label. The main purpose of the study is to determine if the immune responses to 13vPnC are comparable to the immune responses to 7vPnC and if the immune responses to 13vPnC given with DTaP are comparable to those induced by DTaP given alone. In addition, the study aims to evaluate the side effects (safety profile) after vaccination of 13vPnC and 7vPnC when given with DTaP in healthy Japanese infants.

Percentage of participants achieving predefined antibody threshold >=0.35 mcg/mL along with the corresponding 95% confidence interval (CI) for the 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. Exact 2-sided CI based on the observed proportion of participants. To demonstrate non-inferiority, for 6 additional serotypes in 7vPnC + DTaP group, the lowest response observed among the 7 common serotypes in the group was taken as reference.
Measured: 1 month after the infant series
Geometric Mean Concentration (GMC) of Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody for 7 Common Serotypes 1 Month After the Infant Series
Antibody geometric mean concentration (GMC) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) 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.
Measured: 1 month after the infant series
Percentage of Participants Achieving Predefined Antibody Levels for Diphtheria Toxoid, Tetanus Toxoid, and Pertussis Antigens 1 Month After the Infant Series
Predefined antibody levels were 0.1 International Units/mL (IU/mL) for diphtheria, 0.01 IU/mL for tetanus, 5 Enzyme-linked Immunosorbent Assay (ELISA) units/mL (EU/mL) for pertussis toxoid (PT), and 5 EU/mL for filamentous hemagglutinin (FHA).
Measured: 1 month after the infant series

GMs were calculated using all participants with available data for the specified blood draw. To demonstrate non-inferiority, for 6 additional serotypes in 7vPnC + DTaP group, the lowest GMC observed among the 7 common serotypes in the group was taken as reference.
Measured: 1 month after the infant series

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Subjects will be randomly assigned to 1 of 3 groups to receive the following vaccines: Group 1: 13-valent pneumococcal conjugate vaccine (13vPnC) and diphtheria, tetanus, and acellular pertussis vaccine (DTaP), Group 2: 7-valent pneumococcal conjugate vaccine (7vPnC) and DTaP, Group 3: DTaP alone. Group 3 subjects will also receive catch-up doses of Prevenar (commercial product of Prevenar in Japan) 13vPnC and 7vPnC will be blinded, and DTaP will be open-label. The main purpose of the study is to determine if the immune responses to 13vPnC are comparable to the immune responses to 7vPnC and if the immune responses to 13vPnC given with DTaP are comparable to those induced by DTaP given alone. In addition, the study aims to evaluate the side effects (safety profile) after vaccination of 13vPnC and 7vPnC when given with DTaP in healthy Japanese infants.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 13-valent pneumococcal conjugate vaccine (13vPnC), diphtheria, tetanus, and acellular pertussis vaccine (DTaP) and 7-valent pneumococcal conjugate vaccine (7vPnC) in people with Healthy Subjects, run by Pfizer at 32 sites in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 32 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Oct 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants Achieving Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody Level Greater Than or Equal to (>=) 0.35 Microgram Per Milliliter (mcg/mL) 1 Month After the Infant Series (time frame: 1 month after the infant series). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01200368, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2018.
