A Study to Assess Efficacy and Safety of Baxdrostat in Participants With Primary Aldosteronism

This is a Phase III, multicentre, randomised, double-blind, placebo-controlled, parallel-group study to evaluate the safety, tolerability, and efficacy of baxdrostat versus placebo, on the reduction of Seated Blood Pressure (SBP) and achieving normalization of the Renin Angiotensin Aldosterone System (RAAS) in approximately 250 participants ≥ 18 years of age with Primary Aldosteronism (PA), with or without prior treatment with Mineralocorticoid Receptor Antagonists (MRAs) or potassium-sparing diuretics. Baxdrostat (or placebo) will be administered once daily, up-titrated after 2 weeks based on clinical response and tolerability. The study is planned to be conducted globally in approximately 90 study centres and 12 countries.
