RADNOR, Pa., Aug. 13, 2024 (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 dysregulated aldosterone, today announced financial results for the second quarter ending June 30, 2024, and provided a corporate update.

“During the first half of 2024, we continued to make progress executing our pivotal development program for lorundrostat to treat uHTN or rHTN. Considering the current pace of enrollment in the Advance-HTN trial, which is approximately 90 percent enrolled, we anticipate announcing topline data during the first quarter of 2025. To our knowledge, this will be one of the most rigorous trials ever completed for an aldosterone targeted therapy,” stated Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “In addition, we have significantly ramped up enrollment in our pivotal Launch-HTN trial, which is well ahead of schedule compared to our enrollment projections.”

Recent Clinical Highlights and Upcoming Milestones

• Pivotal Advance-HTN Trial – Based on the anticipated timing of full enrollment, the Company is guiding to announce top-line data in the first quarter of 2025. The trial is evaluating the efficacy and safety of lorundrostat for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN), when used as an add-on therapy to a standardized background treatment of two or three antihypertensive medications. In August 2024, the Company met with the FDA and aligned on maintaining the primary endpoint for the Advance-HTN trial as the change in 24-hour ambulatory systolic blood pressure (BP) at week twelve from baseline for active cohorts versus placebo.
• Pivotal Launch-HTN Phase 3 Trial – Enrollment in the Launch-HTN Phase 3 trial is ahead of schedule, with topline data on track to be available in the second half of 2025. This is the second ongoing pivotal trial of lorundrostat for the treatment of subjects with uHTN or rHTN as add-on therapy, who fail to achieve blood pressure control on their existing, prescribed background treatment of two to five antihypertensive medications.
• Explore-CKD Phase 2 Trial – The ongoing trial to evaluate the safety and efficacy of lorundrostat when added to background treatment with SGLT2 inhibitor as a potential therapy to treat patients with uHTN or rHTN and Stage 2 to 3b CKD. The amended protocol is implemented, enrollment is ramping up and we anticipate topline data in the first half of 2025.
• Transform-HTN Open-Label Extension Trial –The Company’s ongoing open-label extension trial allows subjects to continue to receive lorundrostat and obtain additional safety and efficacy data.

Second Quarter 2024 Financial Highlights

Cash, cash equivalents and investments were $311.1 million as of June 30, 2024, compared to $239.0 million as of December 31, 2023. The Company believes that its current cash, cash equivalents and investments will be sufficient to fund its planned clinical studies, as well as support corporate operations, into 2026.

Research and Development (R&D) expenses for the quarter ended June 30, 2024 were $39.3 million, compared to $11.9 million for the quarter ended June 30, 2023. The increase in R&D expenses was primarily due to increases of $22.8 million in preclinical and clinical costs driven by the initiation of the lorundrostat pivotal program in the second quarter of 2023 and the Explore-CKD trial in the fourth quarter of 2023, $2.6 million in clinical supply, manufacturing and regulatory costs, $1.7 million in higher compensation expense resulting from additions to headcount, increases in salaries and accrued bonuses and increased stock-based compensation and $0.3 million in other research and development expenses.

General and Administrative (G&A) expenses were $5.9 million for the quarter ended June 30, 2024, compared to $3.9 million for the quarter ended June 30, 2023. The increase in G&A expenses was primarily due to $1.5 million in higher compensation expense resulting from additions to headcount, increases in salaries and accrued bonuses and increased stock-based compensation and $0.5 million in higher professional fees and other administrative expenses.

Total other income, net was $4.2 million for the quarter ended June 30, 2024, compared to $3.6 million for the quarter ended June 30, 2023. The increase was primarily attributable to increased interest earned on the Company’s investments in money market funds and U.S. treasuries.

Net loss was $41.0 million for the quarter ended June 30, 2024, compared to $12.1 million for the quarter ended June 30, 2023. The increase was primarily attributable to the factors impacting the Company’s expenses described above.

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. Dysregulated aldosterone levels are a key factor in driving hypertension in approximately 25 percent 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 (15%) of U.S. adults have CKD. Diabetes and hypertension are responsible for approximately two-thirds of CKD cases. Early detection and treatment can often keep CKD from getting worse. When CKD progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.

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.

In a Phase 2, proof-of-concept trial (Target-HTN) in uncontrolled or resistant hypertensive subjects, once-daily lorundrostat demonstrated clinically meaningful blood pressure reduction in individuals with uncontrolled hypertension, in both automated office blood pressure measurement and 24-hour ambulatory blood pressure monitoring. 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.
