Lorundrostat Efficacy and Safety in Patients with Uncontrolled Hypertension

Aldosterone dysregulation contributes to hypertension. Lorundrostat is an aldosterone synthase inhibitor, but data on its efficacy and safety in patients with hypertension are limited.

In this multicenter, double-blind, randomized, placebo-controlled trial, we assigned participants who were receiving two to five antihypertensive medications and had a blood-pressure measurement of 140/90 mm Hg or higher obtained during an office visit to undergo a standardized antihypertensive regimen for 3 weeks. Subsequently, participants with an average 24-hour ambulatory blood pressure of 130/80 mm Hg or higher were assigned to receive placebo, lorundrostat at a stable dose of 50 mg daily (the stable-dose group), or lorundrostat at a starting dose of 50 mg daily, with an increase to 100 mg daily if systolic blood pressure was 130 mm Hg or higher after 4 weeks (the dose-adjustment group). The primary end point was the change in 24-hour average systolic blood pressure from baseline to week 12, assessed as the least-squares mean difference from placebo (the placebo-adjusted change) in each lorundrostat group. A key secondary end point was the change in 24-hour average systolic blood pressure from baseline to week 4, assessed as the placebo-adjusted change in the combined lorundrostat groups.
