Mineralys Therapeutics’ Phase 3 Launch-HTN Trial of Lorundrostat Recognized in Inaugural Journal of the American Medical Association (JAMA) “Research of the Year” Roundup

– Launch-HTN, the largest trial of an aldosterone synthase inhibitor conducted among participants with uncontrolled or treatment-resistant hypertension, was one of nine studies selected as most impactful of 2025 by JAMA editors –

RADNOR, Pa., Dec. 12, 2025 (GLOBE NEWSWIRE) -- Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a clinical-stage biopharmaceutical company focused on developing medicines to target hypertension and related comorbidities such as chronic kidney disease (CKD), obstructive sleep apnea (OSA) and other diseases driven by dysregulated aldosterone, announced today that the manuscript highlighting the Company’s Phase 3 Launch-HTN clinical trial evaluating lorundrostat for the treatment of uncontrolled or treatment-resistant hypertension, was featured in JAMA’s inaugural “Research of the Year Roundup,” a curated collection of the most impactful studies published between October 2024 and September 2025.

In introducing this first-ever “Research of the Year Roundup,” JAMA noted that its top editors were asked to nominate their favorite studies based on their importance and impact. The list of nine selected studies spans diverse topics - from hypertension, to dementia and the use of artificial intelligence (AI) - and, according to JAMA, reflects clinical conditions that are of great importance to patients, clinicians, and to the public health community.

Among this select group, JAMA profiled Mineralys’ Launch-HTN trial under the banner “New Hope for Treatment-Resistant Hypertension.” The Launch-HTN trial evaluated the efficacy and safety of lorundrostat, a novel aldosterone synthase inhibitor (ASI), when added to existing background antihypertensive treatment in 1,083 participants with uncontrolled or treatment-resistant hypertension. The trial demonstrated that lorundrostat significantly reduced systolic blood pressure (BP) with a favorable safety and tolerability profile. Launch-HTN recruited a diverse population as reflected in the high proportion of female, Black or African American and elderly participants in the trial.

JAMA highlighted several key findings from the Launch-HTN trial:

• Lorundrostat’s mechanism targets excess aldosterone production, a root cause of hypertension. Unlike existing aldosterone blockers that obstruct the hormone receptor, lorundrostat inhibits the enzyme that produces aldosterone itself, offering a novel mechanism of action.
• When added to existing background treatment, lorundrostat 50 mg dosed once daily demonstrated clinically meaningful, statistically significant mean reductions in automated office blood pressure (AOBP) with a 16.9 mmHg reduction at Week 6 (-9.1 mmHg placebo adjusted; p-value < 0.0001) that was sustained with a reduction of 19.0 mmHg at Week 12 (-11.7 mmHg placebo adjusted; p-value < 0.0001). These benefits were consistent across age, sex, race, body mass index, and baseline medication regimen.
• Lorundrostat demonstrated a favorable safety and tolerability profile in the Launch-HTN trial, noting that while hyponatremia, hyperkalemia, and reduced kidney function occurred more frequently in the treatment arm, discontinuation rates due to adverse events remained below 1%.
