Summary
The aim of this study is to identify patients with DM at high risk of CVD using elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (>125pg/mL), and (2) intensify therapy using renin-angiotensin system (RAS) antagonists, beta-blockers and sodium glucose co-transporter-2 inhibitors (SGLT2i) for primary prevention of cardiovascular events in this high-risk DM population.
Description
- Rationale
Cardiovascular events are the leading cause of death among patients with diabetes. Early identification of high-risk diabetic (DM) patients for intensification of preventive therapy may prevent cardiovascular events.
- Aims
Among biomarker (N-terminal pro-B-type natriuretic peptide, NT-proBNP)-identified high-risk type 2 DM patients without pre-existing cardiovascular disease, to test if intensive preventive therapy (high dose renin-angiotensin-aldosterone system inhibitors [RAASi], beta-blockade, sodium-glucose co-transporter 2 inhibitors [SGLT2i]) may be associated with reduced cardiovascular events compared to standard of care.
- Design
Prospective multinational randomized open-label, parallel group, active-controlled, two-arm, long-term morbidity and mortality trial involving 5 Asian regions (Singapore, Malaysia, China, Taiwan, India; estimated 6 sites each) with patients followed for 2 years.
- Population
Adults with type 2 DM without known cardiovascular disease (defined as known coronary stenosis > 70%, reduced left ventricular ejection fraction < 40%, or a history of myocardial infarction/coronary revascularization/heart failure hospitalization/stroke/prior non-traumatic lower limb amputation or angioplasty) and with NT-proBNP > 125 pg/mL
- Duration
The goal is to include approximately 2,400 patients. It is estimated that about 3,000 patients with NT-proBNP > 125pg/mL have to be screened. The screen failure rate, for reasons other than NT-proBNP, is anticipated to be approximately 20%. The observation period is planned to last for two years. However, the trial is event driven and will continue until predefined event rate is reached (see sample size calculation). The total trial duration is expected to last for four years (two years of recruitment and a two-year observation period after last patient in). Every patient will remain in the study for two years after randomization.
- Visits
Visit 1:
Pre- Screening
Patients who fulfil the first three pre-screening criteria will proceed for NT-proBNP Point-of-Care (POC) testing:
- Type 2 diabetes for at least 6 months (ADA definition)
- Informed consent
- Check Inclusion/exclusion criteria
- NT-proBNP (assessed through local point of care device) *If the results for NT-proBNP fall > 125pg/mL, the patients will proceed for Full-Screening.
