Anti-pneumococcal cross-reactive serotypes were 6A and 19A.
Measured: One month after primary immunization (month 4)
Number of Subjects With Opsonophagocytic Activity Against Vaccine Pneumococcal Serotypes
Vaccine pneumococcal serotypes included 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F, and 23F.
Opsonophagocytic activity was defined as the dilution of serum (opsonic titer) able to sustain 50% killing of live pneumococci under the assay conditions. The cut-off of the assay was an opsonic titer equal to or greater than 8.
Measured: One month after primary immunization (month 4)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Pneumococcal conjugate vaccine GSK1024850A (different lots), Infanrix hexa and Infanrix-IPV/Hib in people with Infections, Streptococcal, run by GlaxoSmithKline at 5 sites in 2 countries.
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 5 inclusion and 15 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 17 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Singapore, Malaysia. 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 19 Nov 2010). 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?
Concentrations of Antibodies Against Vaccine Components of the Pneumococcal Vaccine (time frame: One month after primary immunization (month 4)). 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 NCT00808444, 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 17 Aug 2018.
