RADNOR, Pa., Nov. 11, 2023 (GLOBE NEWSWIRE) -- Mineralys Therapeutics, Inc. (NASDAQ:MLYS), a clinical-stage biopharmaceutical company focused on developing medicines to target hypertension, chronic kidney disease (CKD) and other diseases driven by abnormally elevated aldosterone, today presented data from the Target-HTN Phase 2 trial that further defines an endotype-specific targeted approach for treating uncontrolled or resistant hypertension with lorundrostat, a highly selective aldosterone synthase inhibitor. The data were presented in a poster at the American Heart Association (AHA) Scientific Sessions 2023, which is being held in Philadelphia from November 11th –13th.

Data previously presented from Target-HTN showed that elevated body mass index (BMI) was predictive of an enhanced reduction in systolic blood pressure (BP) from lorundrostat treatment. The poster presented at the AHA Scientific Sessions 2023 included a new analysis of serum leptin levels among subjects in the trial, which showed that increased BMI was correlated with increased leptin circulation. This is consistent with emerging evidence of a leptin-driven, positive feedback loop between obesity, aldosterone and hypertension.1     

"Through our ongoing analyses of data from the Target-HTN trial, a profile of which patients can benefit the most from lorundrostat is emerging. After examining serum leptin levels across participants, we now have evidence that this hormone, along with elevated BMI, could be a biomarker for patients who may experience a meaningful blood pressure reduction from lorundrostat treatment," stated David Rodman, M.D., Chief Medical Officer for Mineralys. "Obesity is an epidemic and is one of the strongest risk factors for developing hypertension, which results in subsequent poor outcomes if uncontrolled. Being able to identify a hypertensive endotype, and intervene early with aldosterone-targeted therapy, would change the way clinicians currently treat the condition in practice by introducing a precision approach to care."

A pre-specified analysis from Target-HTN showed that subjects with a BMI >30kg/m2 experienced placebo-adjusted reductions in systolic BP of 16.7mmHg (p=0.002) and 12.3mmHg (p=0.03) with lorundrostat 50mg and 100mg once-daily (QD) doses, respectively. Findings from the new analysis showed that the same BMI range was associated with a 75% increase in mean serum leptin (21.6 ±1.9ng/mL in subjects with a BMI ≤30kg/m2 compared to 37.8 ±2.4ng/mL in subjects with a BMI >30kg/m2; p<0.001), indicating that increased circulating leptin may be a useful biomarker to identify lorundrostat-responsive individuals.

The Target-HTN trial demonstrated that treatment with lorundrostat at doses of 50mg and 100mg QD led to a statistically and clinically significant reduction of systolic BP in uncontrolled hypertensive individuals on at least two background antihypertensive medications. Full results from the trial were published in the Journal of the American Medical Association (JAMA) and simultaneously presented during a late-breaking science session at the 2023 AHA Hypertension Scientific Sessions in September.

Target-HTN trial results support the transition to late-stage development of lorundrostat as a treatment for uncontrolled or resistant hypertension. The Company's ongoing pivotal development program for lorundrostat to treat uncontrolled or resistant hypertension is currently enrolling subjects in the pivotal Advance-HTN trial, and the second pivotal trial, Launch-HTN, trial is expected to be initiated in the second half of 2023.

About Target-HTN

The Target-HTN (NCT05001945) Phase 2 proof-of-concept trial was a randomized, double-blind, placebo-controlled, dose-ranging, multicenter trial conducted in the U.S. The trial was designed to evaluate the safety, efficacy, tolerability and dose response of orally administered lorundrostat on BP for the treatment of uncontrolled or resistant hypertension when used as add-on therapy to stable background treatment of two or more antihypertensive agents in 200 male and female subjects 18 years of age or older. Five active doses of lorundrostat (12.5mg QD, 50mg QD, 100mg QD, 12.5mg twice daily (BID), and 25mg BID) were compared to placebo in hypertensive subjects. Adverse events observed were a modest increase in serum potassium, decrease in estimated glomerular filtration rate, urinary tract infection and hypertension with one serious adverse event possibly related to study drug being hyponatremia.

About Hypertension

Having sustained, elevated blood pressure (or hypertension) increases the risk of heart disease, heart attack and stroke, which are leading causes of death in the U.S. In 2020, more than 670,000 deaths in the U.S. included hypertension as a primary or contributing cause. Hypertension and related health issues resulted in an average annual economic burden of about $130 billion each year in the U.S., averaged over 12 years from 2003 to 2014.

Less than 50 percent of hypertension patients achieve their blood pressure goal with currently available medications. Abnormally elevated aldosterone levels are a key factor in driving hypertension in approximately 25 percent of all hypertensive patients.

About Lorundrostat

Lorundrostat is a proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uncontrolled hypertension and CKD. Lorundrostat was designed to reduce aldosterone levels by inhibiting CYP11B2, the enzyme responsible for its production. Lorundrostat has 374-fold selectivity for aldosterone-synthase inhibition versus cortisol-synthase inhibition in vitro, an observed half-life of 10-12 hours and demonstrated approximately a 70% reduction in plasma aldosterone concentration in hypertensive subjects.
