Evaluating Baxdrostats Effect on Blood Pressure and Hormone Levels in Adults with Primary Aldosteronism

What this Trial Is About

Researchers are evaluating the safety, tolerability, and effectiveness of baxdrostat compared to a placebo in adults aged 18 years and older with Primary Aldosteronism PA. This Phase III, global study involves approximately 250 participants and aims to reduce seated blood pressure and normalize the Renin Angiotensin Aldosterone System RAAS. Participants may have prior treatment with Mineralocorticoid Receptor Antagonists MRAs or potassium-sparing diuretics. Participants will be randomly assigned to receive either baxdrostat or a matching placebo, both given orally once daily. The dose may be increased after two weeks depending on the participants clinical response and how well they tolerate the medication. The study is conducted across about 90 centers in 12 countries and involves parallel groups. Throughout the study, participants will have their seated systolic blood pressure and RAAS activity measured at week 8 to assess changes from baseline. Additional assessments include monitoring potassium levels, urine aldosterone, and albumin levels up to week 52. Safety and treatment effects will be regularly evaluated during visits. Total participation spans from screening through treatment and follow-up visits as scheduled.
