Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 45 to 79 years with type 2 diabetes and seated blood pressure between 120-139 mm Hg systolic and below 90 mm Hg diastolic.

Probably not a fit

Patients with poorly controlled blood glucose, severe renal impairment, or a history of certain cardiovascular conditions may not benefit from this study.

What this trial studies

This trial investigates the effects of intensive antihypertensive treatment in adults with type 2 diabetes who have high-normal blood pressure. It is a randomized, open-label, parallel-designed, multicenter study aiming to recruit nearly 12,000 patients over three years, with a median follow-up of four years. The primary goal is to determine if lowering systolic blood pressure to below 120 mm Hg can reduce the incidence of major cardiovascular and cerebrovascular events by 20%. Participants will receive a combination of medications including Allisartan and Amlodipine to achieve these targets.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of serious cardiovascular events in patients with type 2 diabetes and high-normal blood pressure.

How similar studies have gone: Other studies have shown that lowering blood pressure in hypertensive individuals with diabetes can lead to improved cardiovascular outcomes, suggesting this approach is promising.
