Study to Evaluate 13 Valent Pneumococcal Conjugate Vaccine (13vPnC) Vaccine Followed by 23-valent Pneumococcal Polysaccharide Vaccine (23vPS) Vaccine in Allogeneic Hematopoietic Stem Cell Transplant Recipients
A Phase 3 study testing 13vPnC and 23vPS in people with Vaccines, Pneumococcal Conjugate Vaccine, run by Pfizer at 47 sites in 10 countries.
Trial summary
People who have received an allogeneic hematopoetic stem cell transplant (HSCT) are more likely than other people to get ill from a germ called Streptococcus pneumoniae. Most people who have had a stem cell transplant are offered a vaccine called 23-valent pneumococcal polysaccharide vaccine (23vPS) to help protect… Read more about this study

About this study
Official title: A Phase 3, Open-label Trial To Evaluate The Safety, Tolerability, And Immunogenicity Of 13-valent Pneumococcal Conjugate Vaccine Followed By 23-valent Pneumococcal Polysaccharide Vaccine In Recipients Of Allogeneic Hematopoietic Stem Cell Transplant Aged 2 Years And Older
People who have received an allogeneic hematopoetic stem cell transplant (HSCT) are more likely than other people to get ill from a germ called Streptococcus pneumoniae. Most people who have had a stem cell transplant are offered a vaccine called 23-valent pneumococcal polysaccharide vaccine (23vPS) to help protect against this germ. The purpose of this study is to evaluate the immune response in HSCT recipients who receive a 13 valent pneumococcal vaccine (13vPnC) followed by 23vPS.
- Conditions
- Vaccines, Pneumococcal Conjugate Vaccine
- Being tested
- 13vPnC, 23vPS
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
13vPnCBiological
0.5mL 13vPnC dose will be administered intramuscularly into the left limb at visits 1,2,3 and 5.
Starting 3-6 months after HSCT 3 doses given at monthly intervals. 4th dose given 6 months after 3rd dose.
23vPSBiological
0.5mL dose of 23vPS will be administered intramuscularly at visit 6. 23vPS given 1 month after 4th dose of 13vPnC.

What is being measured
The primary outcome is the main question the study is designed to answer.
Geometric Mean Fold Rise (GMFR) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody From Before 13vPnC Dose 1 to 1 Month After 13vPnC Dose 3 in All Participants
GMFR for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from before 13vPnC Dose 1 to 1 month after 13vPnC Dose 3 were computed using the logarithmically transformed assay results. Confidence interval (CI) for GMFR were back transformations of a CI based on the Student t distribution for the mean logarithm of the mean fold rise. GMFRs were calculated using all participants with available data from both before 13vPnC Dose 1 and after 13vPnC Dose 3 blood draws.
Measured: Before 13vPnC Dose 1 (pre-vaccination), 1 month after 13vPnC Dose 3
Secondary outcomes (5)
Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody 1 Month After 13vPnC Dose 3 in Pediatric, Adult and All Participants

GMC (13vPnC) and corresponding 2-sided 95 percent (%) CIs were evaluated. Geometric means were calculated using all participants with available data for 1 month after 13vPnC Dose 3 blood draw. CI for GMC are back transformations of a CI based on the Student t distribution for the mean logarithm of the concentrations.
Measured: 1 month after 13vPnC Dose 3

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing 13vPnC and 23vPS in people with Vaccines, Pneumococcal Conjugate Vaccine, run by Pfizer at 47 sites in 10 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 11 inclusion and 20 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 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 47 sites in United States, France, Germany, Belgium, Sweden and 5 more countries. 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 21 Apr 2014). 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?
Geometric Mean Fold Rise (GMFR) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody From Before 13vPnC Dose 1 to 1 Month After 13vPnC Dose 3 in All Participants (time frame: Before 13vPnC Dose 1 (pre-vaccination), 1 month after 13vPnC Dose 3). 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 NCT00980655, 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 Dec 2018.
