Pneumococcal Vaccines Early and in Combination
A Phase 4 study testing Synflorix, Prevenar13 and COMBO in people with Otitis Media, run by Menzies School of Health Research at 1 site in Australia.
Trial summary
The purpose of this study is to determine whether an early schedule of a combination of three doses of PHiD-CV and one dose of PCV13, is superior to three doses of either PCV13 or PHiD-CV. Read more about this study

About this study
Official title: A Randomised Controlled Trial of Pneumococcal Conjugate Vaccines Synflorix and Prevenar13 in Sequence or Alone in High-risk Indigenous Infants (PREV-IX_COMBO): Immunogenicity, Carriage and Otitis Media Outcomes
The purpose of this study is to determine whether an early schedule of a combination of three doses of PHiD-CV and one dose of PCV13, is superior to three doses of either PCV13 or PHiD-CV.
Read the detailed description
Aboriginal children in the Northern Territory (NT) have high rates of otitis media caused by non-capsular H. influenzae (NCHi) and pneumococci. Pneumococcal conjugate vaccine has effectively reduced disease caused by the 7 serotypes. Rates of non-vaccine serotype otitis media (OM), particularly 19A is increasing, and NCHi continues to be a major pathogen in perforations. Parallels with pneumonia are highly probable in this population. Vaccines with expanded and early age protection are needed.
In early 2009 GSK's pneumococcal H. influenzae protein D conjugate vaccine (PHiD-CV) was licensed in Australia. Compared to the current vaccine, 7PCV, this vaccine offers protection from pneumococcal serotypes 1, 5, 7F as well as NCHi (which is a primary pathogen of OM, and possibly pneumonia). However by 2010, a new generation of Wyeth's 7PCV, PCV13 will also be licensed in Australia. Compared to PHiD-CV this vaccine offers protection from additional serotypes 3, 6A and 19A, however it does not offer protection from NCHi infection. There is no empirical evidence to suggest that either vaccine will have superior clinical efficacy for otitis media or pneumonia in high-risk children. The novel combination strategy proposed for this trial has the potential to provide the best of both vaccines.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SynflorixDrug
Also called PHiD-CV
The 10-valent vaccine contains 1 µg of purified capsular polysaccharide of pneumococcal serotypes 1, 5, 6B, 7F, 9V, 14, and 23F conjugated to protein D, 3 µg of serotype 4 conjugated to protein D, 3 µg of serotype 18C conjugated to tetanus toxoid and 3 µg of serotype 19F conjugated to diphtheria toxoid.
Prevenar13Drug
Also called PCV13
The vaccine is a ready to use homogeneous white suspension for intramuscular injection, supplied as a pre-filled syringe.
Active ingredients
Each 0.5 mL dose contains:
2.2 μg of pneumococcal purified capsular polysaccharides for serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F and 23F 4.4 μg of pneumococcal purified capsular polysaccharides for serotype 6B. Each serotype is individually conjugated to non-toxic diphtheria CRM197 protein and adsorbed on aluminium phosphate (0.565 mg). CRM197 is a nontoxic variant of diphtheria toxin isolated from cultures of Corynebacterium diphtheriae strain C7 (β197) grown in a casamino acids and yeast extract-based medium.
COMBODrug
Also called Combination schedule
COMBINATION SCHEDULE of vaccine 1 and vaccine 2: Synflorix (PHiD-CV) at 1,2,4 months then Prevenar13 (PCV13) at 6 months of age.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Synflorix, Prevenar13 and COMBO in people with Otitis Media, run by Menzies School of Health Research at 1 site in Australia.
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 2 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 18 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Australia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Immunogenicity (time frame: 7 months of age). 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 NCT01174849, which also lists 15 linked publications.
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 18 Oct 2018.
