– Submission of New Drug Application (NDA) for lorundrostat planned for late-2025/Q1 2026 – – Completed enrollment in Explore-OSA trial; topline results anticipated in Q1 2026 – – Conference call today at 4:30 p.m. ET – RADNOR, Pa., Nov. 10, 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, today announced financial results for the third quarter ended September 30, 2025, and provided a corporate update. “We are at an exciting point in our company’s history as we prepare for our NDA submission following pre-NDA feedback from the FDA last month. Our team has developed a fulsome data package consisting of multiple clinical trials which have demonstrated a well characterized efficacy and safety profile across distinct populations with uncontrolled and resistant hypertension. These findings for lorundrostat will provide the foundation for an NDA submission which we anticipate submitting near the end of 2025 or during the first quarter of 2026,” stated Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “We continue to evaluate lorundrostat's use in prevalent comorbidities of hypertension, for which normalizing aldosterone production may result in meaningful clinical benefit. Following positive topline data from our Phase 2 Explore-CKD trial, demonstrating successful results in the OSA patient population in our Phase 2 Explore-OSA trial would continue to expand the opportunity for lorundrostat in treating hypertension patients.” Recent Clinical Highlights and Upcoming Milestones Transform-HTN Open-Label Extension Trial – The Company’s open-label extension trial enables participants to continue to receive lorundrostat while allowing the Company to gather ongoing safety and efficacy data.Explore-OSA Phase 2 Trial – Enrollment is complete and topline data is anticipated in the first quarter of 2026. The trial is evaluating the safety and efficacy of lorundrostat in the treatment of overweight or obese participants with moderate-to-severe OSA and hypertension.Strengthened Balance Sheet – On September 4, 2025, the Company completed a public equity financing for gross proceeds of approximately $287.5 million, before deducting fees and expenses. Third Quarter 2025 Financial Highlights Cash, cash equivalents and investments were $593.6 million as of September 30, 2025, compared to $198.2 million as of December 31, 2024. The Company believes that its current cash, cash equivalents and investments will be sufficient to fund its planned clinical trials and regulatory activities, as well as support corporate operations, into 2028. Research and Development (R&D) expenses for the quarter ended September 30, 2025 were $31.5 million, compared to $54.0 million for the quarter ended September 30, 2024. The decrease in R&D expenses was primarily due to a decrease of $26.8 million in preclinical and clinical costs primarily impacted by the conclusion of the lorundrostat pivotal program in the second quarter of 2025, partially offset by increases of $3.2 million in higher compensation expense resulting from additions to headcount, increases in salaries and accrued bonuses and increased stock-based compensation and $1.1 million in higher clinical supply, manufacturing, regulatory and other costs. General and Administrative (G&A) expenses were $9.7 million for the quarter ended September 30, 2025, compared to $6.1 million for the quarter ended September 30, 2024. The increase in G&A expenses was primarily due to $2.2 million in higher compensation expense resulting from additions to headcount, increases in salaries and accrued bonuses and increased stock-based compensation, $1.3 million in higher professional fees and $0.1 million in other administrative expenses. Total other income, net was $4.2 million for the quarter ended September 30, 2025, compared to $3.8 million for the quarter ended September 30, 2024. The increase was primarily attributable to increased interest earned on investments in money market funds and U.S. treasuries as a result of higher average cash balances invested during the quarter ended September 30, 2025. Net loss was $36.9 million for the quarter ended September 30, 2025, compared to $56.3 million for the quarter ended September 30, 2024. The decrease was primarily attributable to the factors impacting the Company’s expenses described above.

About Hypertension Having sustained, elevated blood pressure (or hypertension) (BP) 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 hypertension patients achieve their BP goal with currently available medications. Dysregulated aldosterone levels are a key factor in driving hypertension in approximately 30% of all hypertensive patients. About Chronic Kidney Disease (CKD) CKD, which is characterized by the gradual loss of kidney function, is estimated to affect more than 10% of the global population and is one of the leading causes of mortality worldwide. According to the U.S. Centers for Disease Control and Prevention (CDC), an estimated 1-in-7 (approximately 37 million) U.S. adults have CKD, and approximately 22 million people in the United States are living with both hypertension and CKD. The relationship between these conditions is tightly linked: sustained hypertension may contribute to impaired kidney function, and progressive decrease in kidney function may lead to worsening BP control. When CKD is present in patients with hypertension, the risk of cardiovascular disease and mortality rises significantly. Emerging evidence points to dysregulated aldosterone as a key driver of both diseases. Excess aldosterone promotes sodium retention, vascular inflammation, and fibrosis, contributing to both uncontrolled BP and kidney injury. Despite the availability of existing therapies, a significant proportion of patients remain uncontrolled or undertreated. Early detection and targeted interventions that address underlying mechanisms, such as aldosterone dysregulation, may offer the potential to slow CKD progression, reduce cardiovascular risk, and improve long-term outcomes. Without effective management, CKD can advance to kidney failure, requiring dialysis or transplantation. About Obstructive Sleep Apnea (OSA) OSA is characterized by repetitive overnight hypoxic episodes and subsequent sleep fragmentation due to a complete or partial collapse of the upper airway. Moderate to severe OSA is associated with increased production of aldosterone and increased nighttime BP; standard treatment with positive airway pressure is not sufficient for BP reduction. OSA impacts almost one billion people globally, including 425 million moderate-to-severe cases. Around 80% of adults with OSA are undiagnosed. As of 2015, undiagnosed OSA is estimated to cost the United States approximately $149.6 billion annually from comorbid disease, workplace accidents, motor vehicle accidents and loss of workplace productivity. Between 30-50% of adults with hypertension have OSA, and this number increases to between 70-80% in adults with rHTN. Additionally, untreated moderate-to-severe OSA increases the risk of rHTN. Along with hypertension, OSA is a major risk factor of cardiovascular disease, type-2 diabetes mellitus and stroke. About Lorundrostat Lorundrostat is a proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN), as well as CKD and OSA. 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 a 40-70% reduction in plasma aldosterone concentration in hypertensive participants. The Company has now completed four successful clinical trials of lorundrostat supporting the efficacy and safety profile while also validating aldosterone as an integral therapeutic target in uHTN and rHTN. The Company has completed two pivotal, registrational trials, including the Phase 3 Launch-HTN trial and Phase 2 Advance-HTN trial, which support the robust, durable and clinically meaningful reductions in systolic BP by lorundrostat. Lorundrostat was well tolerated in both trials with a favorable safety profile.
