RADNOR, Pa., Nov. 02, 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 a new post-hoc analysis from the Target-HTN Phase 2 trial of lorundrostat, a highly selective aldosterone synthase inhibitor, in individuals with uncontrolled hypertension (uHTN) and resistant hypertension (rHTN). The data were presented during the Late-Breaking Posters session at the American Society of Nephrology (ASN) Kidney Week 2023, which is being held in Philadelphia from November 2–5.
In this new analysis, investigators identified a population of responders to lorundrostat who experienced a median reduction in systolic blood pressure (BP) of 32 millimeters of mercury (mmHg). The enhanced response was proportional to the elevation in body mass index (BMI) and may indicate an obesity-related, aldosterone-dependent hypertensive endotype.
“We were able to show in this post-hoc analysis additional evidence corroborating the association between BMI and blood pressure reduction with lorundrostat. Individuals trying to manage obesity and hypertension in tandem are at an increased risk for poor outcomes, and a treatment that can provide an enhanced response to this population holds great promise,” stated David Rodman, M.D., Chief Medical Officer for Mineralys. “We continue to believe that we’re entering a precision-medicine era when it comes to hypertension treatments – an era in which physicians can identify and confidently prescribe an anti-hypertensive treatment for each patient according to their underlying biological factors, such as obese individuals with aldosterone-dependent hypertension.”
Consistent with the pre-specified categorical analysis from Target-HTN that demonstrated an enhanced treatment response in individuals with an elevated BMI, a post-hoc linear regression analysis demonstrated a statistically significant association between BMI and reduction in systolic BP in subjects with a BMI ranging from 22.5 to 40kg/m2. The modeled reduction in observed systolic BP was approximately 12mmHg at a BMI of 30kg/m2, and 19mmHg at a BMI of 40kg/m2. The distribution of responses was substantially left-skewed, with the upper quartile of subjects having a median reduction in systolic BP of approximately 32mmHg.
The Target-HTN trial demonstrated that treatment with lorundrostat at doses of 50mg and 100mg once daily (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 American Heart Association (AHA) Hypertension Scientific Sessions in September.
Target-HTN trial results support the transition to late-stage development of lorundrostat as a treatment for uncontrolled and resistant hypertension. The Company’s ongoing pivotal development program for lorundrostat to treat uHTN and rHTN is currently enrolling subjects in the Advance-HTN trial, and the Phase 3 Launch-HTN trial is expected to be initiated before the end of the year.

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 and 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
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
