Key result
Baxdrostat lowers seated SBP by ~10 mmHg vs. placebo in uncontrolled hypertension.
Why the study?
Many patients with hypertension remain unable to achieve adequate blood pressure control despite multiple available therapies, with excess aldosterone contributing to resistant hypertension.
Does baxdrostat reduce systolic blood pressure in adults with uncontrolled or resistant hypertension?
Does baxdrostat reduce systolic blood pressure in adults with uncontrolled or resistant hypertension?

Baxdrostat, a first-in-class selective aldosterone synthase inhibitor, provides clinically meaningful blood pressure reductions in patients with uncontrolled or resistant hypertension without causing clinically significant cortisol suppression.

“My hope is that we are entering an era where we can achieve better blood pressure control rates, given that some estimates suggest less than 30% of patients with hypertension in the United States have their blood pressure controlled. A major question that remains unanswered is how easily patients will be able to access new, nongeneric medications to treat hypertension. The field has so many generic drugs that the hoops clinicians will need to go through after prescribing baxdrostat, such as step therapy or prior authorization, remain unclear.”
“We have been waiting for an innovative medication like Baxfendy for hypertension for many years. Its novel way of lowering blood pressure has the potential to transform clinical practice by targeting a root cause of persistently uncontrolled hypertension. In addition, the nearly double-digit placebo-adjusted systolic blood pressure reduction achieved with Baxfendy is exciting and clinically meaningful for clinicians and patients. Epidemiological data indicate that a 10 mmHg decrease in systolic blood pressure is associated with a roughly 20% lower risk of serious cardiovascular events.”
“Innovation in pharmacotherapy for hypertension, including new targets like aldosterone synthase, opens doors to new frontiers in biologically-directed therapy and new hope for improved control of resistant disease.”
May support addition to regimens for uncontrolled hypertension; leaves open guideline positioning and outcome trials.
Despite the availability of multiple antihypertensive therapies, many patients remain unable to achieve adequate blood pressure control. Excess aldosterone is a key contributor to resistant and uncontrolled hypertension. Baxdrostat (Baxfendy ® ), a first-in-class selective aldosterone synthase (CYP11B2) inhibitor, was approved on May 15, 2026, for use in adults with inadequately controlled hypertension receiving other antihypertensive medications. Unlike mineralocorticoid receptor antagonists, baxdrostat reduces aldosterone biosynthesis while preserving cortisol production, offering a distinct mechanism of action. In phase 3 clinical trials, once-daily baxdrostat (1–2 mg) produced placebo-adjusted reductions of ~ 9–10 mmHg in seated systolic blood pressure. Hyperkalemia was generally manageable, with no clinically meaningful cortisol suppression observed. These findings support baxdrostat as a promising new option for patients with difficult-to-control hypertension.

Ali et al. (2026) conducted a review in Uncontrolled hypertension (n=796). Baxdrostat vs. Placebo was evaluated on Least-squares mean reduction in seated systolic blood pressure from baseline at week 12 (MD -9.8 mmHg, 95% CI -12.6 to -7.0, p=<0.001). Baxdrostat 2 mg once daily significantly reduced seated systolic blood pressure by a placebo-adjusted 9.8 mmHg at 12 weeks in adults with uncontrolled hypertension.
