RADNOR, Pa., March 21, 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 abnormally elevated aldosterone, today announced financial results for the fourth quarter and full year ending December 31, 2023, and provided a corporate update.

“Throughout 2023 we accomplished key milestones that put us in a position to execute our pivotal development plan for lorundrostat for the treatment of hypertension, as well as adjacent conditions including chronic kidney disease,” stated Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “In 2024, we are working towards achieving several clinical events, which we expect to expand the data package for lorundrostat. We believe aldosterone, like obesity, is a significant driver of cardiorenal metabolic conditions and our pursuit of developing an aldosterone targeted approach has the potential to impact millions of patients impacted by these conditions.”

Recent Corporate and Clinical Highlights

• Pivotal Launch-HTN Phase 3 Trial – In the fourth quarter of 2023, the Company initiated the Launch-HTN trial, the second ongoing pivotal trial of lorundrostat for the treatment of patients with uHTN or rHTN, when added to subjects’ existing background hypertension treatment.
• Pivotal Advance-HTN Trial – The first of the two ongoing pivotal trials, the Advance-HTN trial is evaluating the safety and efficacy of lorundrostat for the treatment of uHTN or rHTN, when used as an add-on therapy to an AHA guidelines-based standardized background treatment regimen of either two or three antihypertensive medications.
• Open-Label Extension Trial – In mid-2023, the Company initiated an open-label extension trial to allow subjects to continue to receive lorundrostat and obtain additional safety and efficacy data.
• BMI Data from Target-HTN Phase 2 Trial – The Company presented data from a new analysis of serum leptin levels among subjects in the Target-HTN Phase 2 trial, which showed that increased BMI was correlated with both increased leptin and increased aldosterone production. These data expand our understanding of mechanisms that may link the increasing prevalence of obesity to a parallel increase in uncontrolled and resistant hypertension. These data were presented at the American Heart Association (AHA) Scientific Sessions in Q4 2023.
• Expanded Management Team – Appointed Minji Kim, Ph.D. as Chief Business Officer. Dr. Kim brings more than two decades of experience in business development, strategic leadership, and scientific research. During her career, she has worked with biotech companies in the U.S. and overseas across broad therapeutic and technical areas.
• Strengthened Balance Sheet – Subsequent to the end of the fourth quarter, the Company completed a private placement financing for gross proceeds of approximately $120 million, before deducting fees and expenses.

Key Upcoming Milestones

• Pivotal Advance-HTN Trial – Enrollment in the study is on track to announce topline data in the fourth quarter of 2024.
• Phase 3 pivotal Launch-HTN Trial – Topline data from this trial is expected in the second half of 2025.
• Explore-CKD Phase 2 Trial – The trial design is being modified, including allowing all subjects to use concurrent SGLT2 inhibitors, which have become the standard of care in CKD, and reducing the eGFR cutoff to 30ml/min/1.73m2 for all trial participants, obviating the need for Part B of the trial. The trial remains on track to report topline data in the fourth quarter of 2024 to the first quarter of 2025.
  

Fourth Quarter and Annual 2023 Financial Highlights

Cash, cash equivalents and investments were $239.0 million as of December 31, 2023, compared to $110.1 million as of December 31, 2022. In February 2024, the Company completed a private placement financing for gross proceeds of approximately $120 million, before deducting offering expenses. 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 were $70.4 million for the year ended December 31, 2023, compared to $26.3 million for the year ended December 31, 2022. R&D expenses for the quarter ended December 31, 2023 were $23.7 million, compared to $7.8 million for the quarter ended December 31, 2022. The annual increase in R&D expenses was primarily due to increases of $21.4 million in preclinical and clinical costs, driven by the initiation of the lorundrostat pivotal program beginning in the second quarter of 2023, $9.0 million in license fees upon achieving development milestones of lorundrostat in 2023, $7.8 million in clinical supply, manufacturing, and regulatory costs, $5.6 million in higher compensation expense resulting from additions to headcount and stock-based compensation and $0.3 million in other research and development expenses.

General and Administrative (G&A) expenses were $14.3 million for the year ended December 31, 2023, compared to $5.2 million for the year ended December 31, 2022. G&A expenses were $4.0 million for the quarter ended December 31, 2023, compared to $2.2 million for the quarter ended December 31, 2022. The annual increase in G&A expenses was primarily due to $3.8 million in higher professional fees associated with operating as a public company, $3.4 million in higher compensation expenses resulting from additions to headcount and stock-based compensation, $1.1 million of higher insurance expenses primarily associated with new director and officer insurance policies and $0.8 million in higher other administrative expenses.

Total other income, net was $12.8 million for the year ended December 31, 2023, compared to $1.7 million for the year ended December 31, 2022. Total other income, net was $3.3 million for the quarter ended December 31, 2023, compared to $0.9 million for the quarter ended December 31, 2022. The annual increase was primarily attributable to increased interest earned on the Company’s investments in money market funds and U.S. treasuries.

Net loss was $71.9 million for the year ended December 31, 2023, compared to $29.8 million for the year ended December 31, 2022. Net loss was $24.4 million for the quarter ended December 31, 2023, compared to $9.1 million for the quarter ended December 31, 2022. The annual 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. Abnormally elevated 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.
