Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes
Primary outcome [1] 295007 0
The primary outcome will be a composite of major CVD events: fatal and non-fatal acute coronary syndrome and ischaemic stroke, ascertained by linkage with AIHW and NDI. The following ICD-10 codes will be included: I20 (unstable angina), I21 (acute myocardial infarction) and I63 (cerebral infarction). Cardiovascular events will be assessed through data linkage to medical records.
Timepoint [1] 295007 0
6 years after randomisation, with interim analysis at 3 years after randomisation
Secondary outcome [1] 314568 0
Myocardial Infarction is assessed through data linkage to in patient medical records (diagnosis by ICD code)
Timepoint [1] 314568 0
5 years after randomisation, with interim analysis at 3 years after randomisation
Secondary outcome [2] 314569 0
Stroke is assessed through data linkage to in patient medical records (diagnosis by ICD code)
Timepoint [2] 314569 0
6 years after randomisation, with interim analysis at 3 years after randomisation

Eligibility
Key inclusion criteria
Men and women aged 55-60 years with no known CVD events and two or more risk factors for CVD. Risk factors include hypercholesterolaemia, hypertension, elevated BMI, and elevated waist circumference.
Minimum age
55 Years
Maximum age
60 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Previous pneumococcal vaccination, previous cardiovascular events and any other condition for which the use of the vaccine is indicated (as per the Australian Immunisation Handbook).

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
There will be a mailout to community dwelling residents in the target age range through the Department of Human Services. Recruitment methods have been expanded to include social media (e.g. Facebook), health and medical websites (e.g. Stroke Foundation), and other means of promotion (e.g. Research Newsletters). Respondents will reply by completing a screening survey to ascertain eligibility by surface mail or via web. Once eligibility criteria are verified again at the clinic, randomisation will be stratified by gender and centre, using a web-based randomization system; allocation will also be concealed by this system as participants will be randomised to group A or B. The study Nurse will draw up the allocated study drug in a room away from the participant. Participants will receive active or control vaccination, the latter being a saline syringe identical in appearance to the vaccine.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
There will be a computer generated randomisation system that will be accessed online. The randomisation will be stratified by each centre.

Efficacy
Statistical methods / analysis
Due to slow recruitment (3000 over 1 year rather than 6000), the recruitment period was extended to 2 years and 4725 were enrolled and randomised by the end of 2017. In order to accommodate this reduction in the total sample size, power calculations have been modified to reflect 4725 people followed for a longer period, i.e 6 years after the end of recruitment. This should still enable us to detect a HR of 0.84 with 80% power at p=0.05 (two-sided), assuming a similar event rate. To accommodate the longer follow-up period, an interim analysis has been added 3 years after the end of follow-up (median 4 years follow-up). The interim analysis will check the overall event rate in the entire cohort; if this is lower than anticipated in the power calculation, an independent statistical committee will be convened to recommend a revised analysis plan to the steering committee. If the event rate is as anticipated, the follow-up period will continue as planned to 6 years.
