RADNOR, Pa., March 15, 2023 (GLOBE NEWSWIRE) — Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a clinical-stage biopharmaceutical company focused on developing medicines to target diseases driven by abnormally elevated aldosterone, today announced financial results for the fourth quarter and full year ending December 31, 2022, and provided a corporate update.

“I am extremely proud of the Mineralys Therapeutics team as we continue to make tremendous progress advancing the clinical development of lorundrostat – our proprietary highly selective aldosterone synthase inhibitor designed to reduce aldosterone levels – for the treatment of hypertension. This is a critical milestone in our Company’s history, as we prepare to initiate the pivotal program to evaluate the safety and efficacy of lorundrostat for the treatment of uncontrolled and resistant hypertension in the first half of 2023,” stated Jon Congleton, Chief Executive Officer of Mineralys Therapeutics. “Uncontrolled and resistant hypertension continue to impact individual patient’s lives and the healthcare system at large. The closing of our IPO in February enables us to continue our efforts of developing a targeted treatment approach for hypertension with lorundrostat.”

Recent Corporate and Clinical Highlights

  • Topline Data Target-HTN Phase 2 trial – In November 2022, the Company announced positive topline data from its Target-HTN trial, a Phase 2 proof-of-concept trial for lorundrostat in the treatment of uncontrolled hypertension (uHTN) and resistant hypertension (rHTN), which support advancing the development of lorundrostat into the planned pivotal clinical program.
  • FDA End of Phase 2 Meeting – In November 2022, the Company held an end of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to review the positive results of the Target-HTN trial, and to discuss the plans for a pivotal program for lorundrostat in hypertension. Based on the Phase 2 results and feedback from the FDA, the Company intends to initiate the pivotal program in the first half of 2023.
  • Presented Phase 2 Results at ACC.23/WCC – In March 2023, the Company presented positive data from the Target-HTN Phase 2 study that demonstrated clinically meaningful blood pressure reduction with once-daily dosing of lorundrostat at the American College of Cardiology’s 72nd Annual Scientific Session together with the World Congress of Cardiology (ACC.23/WCC), including a pre-specified analysis of hypertensive subjects with a body mass index (BMI) ≥30 kg/m2 (obese) that showed lorundrostat demonstrated a statistically significant placebo-adjusted reduction in systolic blood pressure.
  • Presented Phase 1 Results at ACC.23/WCC – In March 2023, the Company presented Phase 1 data from a first-in-human, safety, tolerability, pharmacokinetics, and pharmacodynamics study – conducted by Mitsubishi Tanabe Pharma – of single ascending dose and multiple ascending doses of lorundrostat that showed it was well-tolerated and had the predicted effect of suppressing aldosterone in a dose-dependent fashion without inhibiting cortisol.
  • Completed an Initial Public Offering (IPO) – In February 2023, the Company completed an initial public offering of 13.8 million shares of common stock at a price of $16.00 per share for net proceeds of approximately $202.0 million, after deducting underwriting discounts, commissions, and estimated offering-related expenses.
  • NASDAQ Listing – Listed the Company’s common stock on the Nasdaq Global Select Market under the ticker symbol “MLYS.”

Key Upcoming Milestones

  • ADVANCE-HTN Phase 2 pivotal trial – In the first half of 2023, the Company plans to initiate the ADVANCE-HTN Phase 2 trial to evaluate the safety and efficacy of lorundrostat for the treatment of uHTN and rHTN, when used as an add-on therapy to standardized background treatment of two or more antihypertensive medications in up to approximately 300 adult subjects. The topline data from this trial is expected in the first half of 2024.
  • Phase 3 pivotal trial – In the second half of 2023, the Company plans to initiate a randomized, double-blind, placebo-controlled Phase 3 trial to evaluate the safety and efficacy of lorundrostat for the treatment of uHTN and rHTN, when used as an add-on therapy to prescribed background treatment of two or more antihypertensive medications in up to approximately 1,000 adult subjects. The topline data from this trial is expected in mid-2025.
  • CKD profiling trial – In mid-2023, the Company plans to initiate a randomized, double-blind, placebo-controlled Phase 2 trial to evaluate the safety and efficacy of lorundrostat for the treatment of uHTN and rHTN in a chronic kidney disease (CKD) population. Topline data from this trial expected in the first half of 2024.
  • Open label extension trial for long-term safety exposure – In mid-2023, the Company plans to initiate an open label extension trial to obtain additional safety data – all subjects in the pivotal hypertension program, including the ADVANCE and Phase 3 trials will be given the opportunity to participate.

Fourth Quarter and Full-Year 2022 Financial Highlights
Research and Development (R&D) expenses were $26.3 million for the full year ended December 31, 2022, compared to $16.3 million for the full year ended December 31, 2021. R&D expenses for the three months ended December 31, 2022, were $7.8 million, compared to $6.6 million for the three months ended December 31, 2021. The increase in full-year R&D expenses was primarily due to increases of $7.4 million in preclinical and clinical costs related to the research and development of lorundrostat, $1.7 million for clinical supply, manufacturing, and regulatory costs, and $0.9 million in personnel expenses for additional employees to support research and development.

General and Administrative (G&A) expenses were $5.2 million for the full year ended December 31, 2022, compared to $2.4 million for the full year ended December 31, 2021. G&A expenses were $2.2 million for the three months ended December 31, 2022, compared to $0.5 million for the three months ended December 31, 2021. The increase in full-year G&A expenses was primarily due to higher professional fees of $1.7 million related to accounting, legal, and other support, and personnel expenses of $1.1 million associated with additional employees.

Net loss was $29.8 million for the full year ended December 31, 2022, compared to $19.4 million for the full year ended December 31, 2021. The increase was primarily attributable to the factors described above.

Cash, cash equivalents, and marketable securities were $110.1 million as of December 31, 2022, compared to cash and cash equivalents of $10.6 million as of December 31, 2021. Subsequent to December 31, 2022, Mineralys Therapeutics completed an IPO of the Company’s common stock for net proceeds of approximately $202.0 million, after deducting underwriting discounts, commissions, and estimated offering-related expenses.

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 Lorundrostat
Lorundrostat is a proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uncontrolled hypertension. 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 and an observed half-life of 10-12 hours. In a Phase 2, proof-of-concept study (Target-HTN) in uncontrolled and 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.
