Study Evaluating Persistence Of Antibody Response Elicited By 13vPnC In Healthy Adults Previously Vaccinated
A Phase 3 study testing Blood draw in people with Healthy, run by Pfizer at 29 sites in United States.
Trial summary
The purpose of this study is to evaluate the levels of antibodies 1 year after receiving the second vaccine dose in two groups of adults over the age of 60: (1) those who have previously received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) and (2) those who have previously received 1 dose of 13vPnc… Read more about this study

About this study
Official title: A Study To Evaluate The Persistence Of The Antibody Response Elicited By 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) In Healthy Adults Who Have Previously Been Vaccinated With Either 2 Doses Of 13vPnC Or 13vPnC And 23-Valent Pneumococcal Polysaccharide Vaccine In Different Sequential Order In Study 6115A1-3010 Or 6115A1 3005
The purpose of this study is to evaluate the levels of antibodies 1 year after receiving the second vaccine dose in two groups of adults over the age of 60: (1) those who have previously received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) and (2) those who have previously received 1 dose of 13vPnc and 1 dose of 23-valent pneumococcal polysaccharide vaccine (23vPS). This study will also assess whether the use of the 2 vaccines, 13vPnC and 23vPS, administered in different sequential order results in different prolonged antibody levels. This study is limited to individuals who participated in either study 6115A1-3010 (NCT00574548) or 6115A1-3005 (NCT00546572).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the levels of antibodies 1 year after receiving the second vaccine dose in two groups of adults over the age of 60: (1) those who have previously received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) and (2) those who have previously received 1 dose of 13vPnc and 1 dose of 23-valent pneumococcal polysaccharide vaccine (23vPS). This study will also assess whether the use of the 2 vaccines, 13vPnC and 23vPS, administered in different sequential order results in different prolonged antibody levels. This study is limited to individuals who participated in either study 6115A1-3010 (NCT00574548) or 6115A1-3005 (NCT00546572).

Primary outcome
Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titer (GMT) Antibody Persistence 1 Year After Vaccination (Vax) 2 in Parent Study 6115A1-3010 (NCT00574548)
Time frame: Month 1/Year 2 (Baseline) (Follow-up Study 6115A1-3018; NCT01025336)
Antibody GMTs as measured by OPA assay for 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Confidence intervals (CIs) for the GMTs are back transformations of a confidence interval based on the Student t distribution for the mean logarithm of the titers.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Blood draw in people with Healthy, run by Pfizer at 29 sites in United States.
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 1 inclusion and 1 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 20 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 29 sites in United States. 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 20 Jun 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?
Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titer (GMT) Antibody Persistence 1 Year After Vaccination (Vax) 2 in Parent Study 6115A1-3010 (NCT00574548) (time frame: Month 1/Year 2 (Baseline) (Follow-up Study 6115A1-3018; NCT01025336)). The study lists 2 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 NCT01025336, 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 20 Jun 2012.
