RADNOR, Pa., Oct. 01, 2026 (GLOBE NEWSWIRE) — Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a biopharmaceutical company focused on developing medicines to target hypertension and aldosterone-related adverse outcomes in comorbid conditions such as chronic kidney disease, obstructive sleep apnea (OSA) and other diseases driven by dysregulated aldosterone, today announced that five abstracts will be presented at the American Heart Association (AHA) Hypertension Scientific Sessions 2026, taking place October 7-11 in Arlington, VA.

About Launch-HTN 
The Launch-HTN trial (NCT06153693) was a global, randomized, double-blind, placebo-controlled Phase 3 clinical trial of adults whose blood pressure remained uncontrolled despite being on two to five antihypertensive medications. Participants were assigned to one of three groups: lorundrostat 50 mg once daily; lorundrostat 50 mg once daily with the option to increase to 100 mg at week six based on prespecified criteria; or placebo. The primary endpoint was change from baseline in systolic blood pressure at six weeks versus placebo, measured by automated office blood pressure monitoring.

About Explore-OSA

The Explore-OSA trial (NCT06785454) was a randomized, double-blind, placebo-controlled, crossover Phase 2 clinical trial. This proof-of-concept trial was designed to evaluate the efficacy, safety and tolerability of lorundrostat in overweight or obese adults with moderate-to-severe OSA and hypertension. Participants in Explore-OSA received lorundrostat 50 mg once daily and placebo in sequential treatment periods, with continuous monitoring of blood pressure during overnight polysomnography. The primary efficacy endpoint of the trial was absolute change from baseline in apnea-hypopnea index after four weeks of active treatment compared to placebo. The first secondary endpoint was automated office blood pressure, and additional endpoints were nighttime blood pressure and sleep and cardiovascular health measures.

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 United States. In 2022, more than 685,000 deaths in the United States included hypertension as a primary or contributing cause. Hypertension and related health issues resulted in an estimated annual economic burden of about $219 billion in the United States in 2019.

Less than 50% of hypertensive patients achieve their blood pressure goal with currently available medications. Dysregulated aldosterone levels are a key factor in driving hypertension in approximately 30% of all hypertensive patients.

About Lorundrostat

Lorundrostat is an investigational, proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN), as well as related comorbidities, such as chronic kidney disease, obstructive sleep apnea and other diseases driven by dysregulated aldosterone. 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, has an observed half-life of 10-12 hours and demonstrated a 40-70% reduction in plasma aldosterone concentration in participants with hypertension.

Mineralys has completed six late-stage clinical trials of lorundrostat supporting its efficacy and safety profile while also validating aldosterone as an integral therapeutic target in uHTN and rHTN. The clinical program includes two pivotal, registrational trials, the Phase 3 Launch-HTN trial and Phase 2 Advance-HTN trial, which support the robust, durable and clinically meaningful reductions in systolic blood pressure by lorundrostat. Lorundrostat was well tolerated in both trials with a favorable safety profile.
