Aldosterone and renin biomarker activity clinically demonstrate how baxdrostat mechanistically achieves selective blood pressure lowering effects with no impact on cortisol
20.3 mmHg reduction in systolic blood pressure, or 11 mmHg (p-value < 0.0001) placebo-adjusted decline at the 2 mg dose
Well-tolerated profile and differentiated mechanism of action supports combination approaches

“We were honored to present our Phase 2 BrigHtn data as part of a late-breaking session focused on new treatments for the increasingly recognized unmet needs in resistant hypertension at this year’s AHA conference,” said
BrigHtn Trial Highlights
Aldosterone and renin activity reinforce the biological mechanism of baxdrostat
- Dose-dependent reduction in both plasma and urine aldosterone support inhibition of aldosterone synthase and the mechanism of action of baxdrostat
- Urine aldosterone levels 24-hours post-treatment quantitatively measure total body aldosterone production with less variation than plasma to provide direct evidence of baxdrostat’s aldosterone lowering capabilities
- Dose-dependent changes in renin activity support physiological salt response
- No meaningful impact on cortisol confirms baxdrostat is highly selective for aldosterone synthase
Clinically meaningful and dose-dependent reduction in blood pressure with baxdrostat
- BrigHtn successfully met its primary endpoint, demonstrating a statistically significant change from baseline in mean seated systolic blood pressure (SBP) versus placebo:
- Dose-dependent reductions in SBP of −20.3 mmHg (2-mg), −17.5 mmHg (1-mg), and −12.1 mmHg (0.5-mg)
- Statistically significant placebo-adjusted decreases of −11.0 (2-mg, P = 0.0001) and −8.1 (1-mg, P = 0.003)
- Secondary endpoint results included baxdrostat significantly lowering diastolic blood pressure (DBP) by 5.2 mmHg in the 2mg dose arm, and approximately 46% of patients in the 2 mg dose arm achieving blood pressure control (SBP less than 130mmHg)
- Patient demographics and baseline characteristics were diverse and well-balanced across treatment arms
Clinical safety and tolerability of baxdrostat support a well-tolerated profile
- No drug related serious adverse events (SAEs) observed or major safety concerns were reported across all three dose cohorts tested after 12 weeks of treatment
- Transient and manageable adverse events of special interest included hypotension, hyponatremia, or elevated potassium levels
- Low discontinuation rate of less than 1% (2 patients) due to transient treatment-related adverse events; all patients completed the study on drug
- Well-tolerated profile and differentiated mechanism of action supports combination approaches
The BrigHtn trial was a Phase 2 randomized, double-blind, placebo-controlled dose-ranging clinical trial designed to assess the safety and efficacy of baxdrostat in subjects who have not achieved their target blood pressure despite receiving three or more antihypertensive agents at their maximally tolerated doses, one of which must be a diuretic. The trial evaluated three active doses of baxdrostat (0.5 mg, 1.0 mg, and 2.0 mg) compared to placebo control in 275 patients randomized across all four dosing cohorts, with 248 patients completing. The primary endpoint of BrigHtn was the change in mean seated SBP from randomization to trial end after 12 weeks of treatment.

About CinCor
CinCor, founded in 2018, is a clinical-stage biopharmaceutical company with a mission to bring innovation to the pharmaceutical treatment of cardio-renal diseases. Its lead asset, baxdrostat (CIN-107), a highly selective, oral small molecule inhibitor of aldosterone synthase, is in clinical development for the treatment of hypertension and primary aldosteronism.
About Baxdrostat (CIN-107)
Baxdrostat is a highly selective, oral small molecule inhibitor of aldosterone synthase, the enzyme responsible for the synthesis of aldosterone in the adrenal gland, in development for patient populations with significant unmet medical needs, including treatment-resistant hypertension and primary aldosteronism. Hypertension, which is defined by the
Forward-Looking Statements
This press release contains certain forward-looking statements, including, but not limited to, statements related to CinCor’s business in general; the therapeutic potential of baxdrostat (CIN-107), including its potential to be an effective treatment for patients with treatment-resistant hypertension, uncontrolled hypertension and CKD, and the ability of baxdrostat to address multiple unmet needs in patients; the potential of baxdrostat to emerge as a new mechanism of action in the hypertension treatment paradigm; and other statements that are not historical facts. Because such statements are subject to risks and uncertainties, actual results may differ from those expressed or implied by such forward-looking statements. Words such as “anticipates,” “believes,” “expected,” “intends,” “plan,” “may”, “will,” “project”, “estimate”, “continue,” “advance” and “future” or similar expressions are intended to identify forward-looking statements.
