Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Inclusion of myocardial mechanics in screening echocardiography for development of cardiotoxicity. Serial screening test for LV strain is envisaged at 3 monthly intervals for a year and the acquisition takes ~30 minutes.
Intervention code [1] 289032 0
Early detection / Screening
Comparator / control treatment
Performance of standard echocardiogram, an ultrasound test of the heart where ejection fraction (EF) is measured. This is an insensitive test for early changes, but is used to ensure that patients with possible cardiotoxicity are managed safely. This screening test is envisaged at 3 monthly intervals for a year and the acquisition takes ~30 minutes.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At risk subjects will be identified by cardiologists, oncologists, general practitioners, or self-referred. We plan to compare 138 subjects with strain vs 138 controls.

Clinical evaluation: All subjects will undertake a clinical history and answer questionnaires on general health status (EQ5D), activity (DASI) and heart failure symptoms (MLHFQ). All will undergo a screening echo for valvular disease. If these results are abnormal, subjects will be excluded.

Study protocol: A central (web-based) randomization program will be used to allocate patients to advanced vs conventional imaging only after the patient is enrolled. This allocation concealment will prevent the person performing recruitment from knowing the allocated group at the time of inclusion. Subsequent management decisions are not based on randomization and will occur as a "usual care' response to data provided from imaging.

Conventional imaging: Limited to evaluation of EF and valve disease. If there is a symptomatic drop of more than 5% of ejection fraction, or a 10% asymptomatic drop of ejection fraction to EF <55% will lead to referral of the patient for initiation and titration of heart failure therapy.

Advanced cardiac imaging: Inclusion of global longitudinal strain. Reduction of global longitudinal strain by >12% in any of the follow-up echocardiograms, as compared to baseline will lead to referral of the patient for initiation and titration of heart failure therapy(see below).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed using a randomisation table created by computer software (i.e. computerised sequence generation). Randomization is stratified on the basis of diabetes status.

Other design features
Those with an abnormal test will be identified as having Stage B heart failure, and undergo better blood pressure and glucose control. Additional protective therapy (ACE inhibitors and beta blockers) will be added and titrated to target dose.

Efficacy
Statistical methods / analysis
Power calculations; Assumptions –
1) cutoff for strain = 11% decrement (Negishi JASE 2014)
2) cutoff for EF = 10% asympt drop to <55% (Seidman AD, JCO 2002)
3) reduction in EF in at risk patients at 3m = 21% (Sawaya, AJC 2011)
4) response to medical Rx in patients with reduced EF=40% (from Cardinale).
5) development of HF in 41% at 3y (from Chen, JACC 2013).
6) reduction in strain in at risk patients = 34% (from submitted “3 toxic regimen” paper by Negishi, using 11% reduction strain).
7) response to therapy based on strain = 90% (from submitted “3 toxic regimen” paper by Negishi, based on 11% reduction strain).% (unpublished observation).
8) Reduction in EF of patients with reduced strain = 14% (from prelim data).

Calculations –These are based on the development of cardiotoxicity in patients with preserved EF. Based on these assumption of 24 vs 40 patients showing cardiotoxicity, a study of 138 patients/group would give 80% power to identify a difference at p<0.05 using an intention-to-treat approach. To allow for drop-outs we will recruit 320 patients.


Primary data analysis will compare the outcomes of patients will be compared with a t-test (change in EF) or survival analysis (heart failure and cessation of treatment). Multivariable models (respectively linear and Cox regression) will be developed to identify effect size, and will be extremely important if groups are mismatched despite randomization. All analyses will be performed on an intention to treat basis. Subsequent analyses will include the same methods to compare differences in the secondary end-points.

The data from all participating investigational sites will be pooled and summarised with respect to demographic and baseline characteristics. Exploratory data analyses will be performed using descriptive statistics. Data will be presented for the complete intent-to-treat (ITT) population (all patients having taken part in a significant proportion of the study but did not complete follow-up data collection and/or had major protocol deviations) as well as the per-protocol population (ITT patients who completed the study).

Survival curves will be constructed using time-dependent, all-cause survival and event-free survival data for all patients on an ITT basis followed by log-rank and Breslow tests to determine differences between groups with respect to the number and/or timing of events. To examine the interactions between risk factors and treatment mode and other potential correlates of event-free survival and all-cause mortality during study follow-up we will construct Cox-Proportional Hazards Models with calculation of relative risk (RR) and 95% confidence interval. Multiple logistic regressions will be used to determine independent correlates of clinical events at fixed time-points.
