CinCor Pharma Announces Publication in the New England Journal of Medicine of Phase 2 BrigHtn Data on Selective Aldosterone Synthase Inhibitor Baxdrostat in Treatment-Resistant Hypertension

Clinically significant and dose-dependent reduction in blood pressure with baxdrostat

Highly selective mechanism of action with no meaningful impact on cortisol supports first-in-class potential

Potential treatment for the 10-12 million patients in the US alone with treatment-resistant hypertension

WALTHAM, Mass., Nov. 07, 2022 (GLOBE NEWSWIRE) — CinCor Pharma, Inc. (“CinCor”) announced that detailed results from the Phase 2 BrigHtn trial evaluating the safety and efficacy of baxdrostat in treatment-resistant hypertension were published online today in the New England Journal of Medicine. Baxdrostat is a highly selective, once daily oral small molecule inhibitor of aldosterone synthase.

“Publication of the Phase 2 BrigHtn data in the world-renowned New England Journal of Medicine highlights to the medical community that resistant hypertension is an important unmet need with inadequate treatment options that fail to bring blood pressure under control,” said Mason Freeman, M.D, Chief Medical Officer at CinCor. “The clinical biomarker activity of aldosterone and renin provide mechanistic insight into how baxdrostat achieves selective blood pressure lowering effects with no impact on cortisol. These findings further reinforce the robust blood pressure lowering capabilities in hypertensive patients on three or more medications, the well-tolerated profile supportive of long-term use and combinability with other agents, and the potential to treat the 10-12 million patients in the US alone with treatment-resistant hypertension.”

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 systolic blood pressure 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 American College of Cardiology and the American Heart Association as resting blood pressure above 130/80 mm Hg, is generally acknowledged to be one of the most common preventable risk factors for premature death worldwide. Though often asymptomatic, hypertension significantly increases the risk of heart disease, stroke, and kidney disease, amongst other diseases. It is estimated that as much as 20% of the global population suffers from hypertension, including nearly one-half of the adult population in the U.S., or 116 million hypertensive patients.
