RADNOR, PA – November 7, 2023 – 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 quarter ending September 30, 2023, and provided a corporate update.
“The third quarter was productive for Mineralys with ongoing progress in our clinical development of lorundrostat, the publication of our proof-of-concept study, Target-HTN, in the Journal of the American Medical Association and the addition of two new Board members. We have finalized the designs of Launch-HTN and Explore-CKD, which we believe strengthens our ability to generate data that will support patients’ real-world needs. We continue to anticipate that the Phase 3 Launch-HTN and the Phase 2 Explore-CKD trials will be initiated by the end of 2023,” stated Jon Congleton, Chief Executive Officer of Mineralys Therapeutics.
Recent Corporate and Clinical Highlights
•Pivotal Advance-HTN trial – The ongoing trial is evaluating the safety and efficacy of lorundrostat for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN), when used as an add-on therapy to standardized background treatment of two or three antihypertensive medications.
•For subjects in the Advance-HTN trial, the treatment withdrawal component of the program has been moved forward from week 48 of treatment in the open-label extension trial to week 12 of Advance-HTN. This amendment was implemented to characterize the durability of changes in blood pressure and other pharmacodynamic measures of efficacy following the double-blind treatment period. Due to this protocol amendment and the Company’s current visibility into the enrollment curve, the Company’s expectations for topline data have been revised from the first half of 2024 to the second half of 2024.
•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 long-term safety and efficacy data. All subjects in the pivotal hypertension program, including the Advance-HTN and Launch-HTN trials, as well as the Explore-CKD trial, will be given the opportunity to participate in the extension trial.
•Late-Breaking Poster Presented at ASN’s Kidney Week 2023 – The late-breaking poster presented at the American Society of Nephrology’s (ASN) Kidney Week 2023 by David Rodman, Chief Medical Officer of Mineralys, highlighted lorundrostat’s potential as the first precision targeted treatment for hypertension. This poster concluded that obesity, and other obesity-associated physiological changes, contribute to an enhanced response to lorundrostat. The poster is titled, “Identification of a hypertensive endotype with a median treatment effect of -32mmHg in response to the novel aldosterone synthase inhibitor lorundrostat”.
•JAMA Published Full Data from Target-HTN Trial – In September 2023, The Journal of the American Medical Association (JAMA) published the results of Target-HTN, the first in patient trial of lorundrostat in individuals with uHTN and rHTN. This paper, authored by doctors Laffin and Nissen at the Cleveland Clinic, reported the robust blood pressure lowering potential of lorundrostat as well as a favorable tolerability profile.
•Expanded Board of Directors - Appointed Daphne Karydas and Glenn Sblendorio to the Company’s Board of Directors, effective September 13, 2023. Ms. Karydas and Mr. Sblendorio bring executive, financial and operational leadership experience in biotechnology and biopharmaceuticals markets. Ms. Karydas was appointed chairperson of the audit committee and Mr. Sblendorio was appointed chairperson of the compensation committee.
Key Upcoming Milestones
•Upcoming Poster Presentation at AHA Scientific Sessions 2023 – The Company has been selected to present a poster at the American Heart Association (AHA) Scientific Sessions 2023, which is being held from November 10 – 13, 2023, in Philadelphia, PA. The poster is titled, “Lorundrostat for Treatment of Obesity-Related, Aldosterone-Dependent Hypertension - An Endotype-Specific, Targeted Approach to the Treatment of Uncontrolled Hypertension”.
•Phase 3 pivotal Launch-HTN trial – In the second half of 2023, the Company remains on track to initiate a randomized, double-blind, placebo-controlled Phase 3 trial to evaluate the safety and efficacy of lorundrostat for the treatment of uHTN or rHTN. Lorundrostat will be studied when used as an add-on therapy to prescribed background treatment of two to five antihypertensive medications in up to approximately 1,000 adult subjects. In keeping with the objective of the trial, to model real world treatment of uHTN and rHTN in the primary care setting, the trial’s primary endpoint will be in-office blood pressure measurement rather than 24-hour ambulatory blood pressure measurement. Based on current projections, the topline data from this trial is now expected in the second half of 2025.
•Explore-CKD Phase 2 trial – The Company expects to initiate a two-part Phase 2 clinical trial for lorundrostat in hypertensive patients with stage 2-3b CKD in the second half of 2023, with topline data expected in the fourth quarter of 2024 to the first quarter of 2025. In consultation with its advisors and based on the significant unmet need, the Company has made the strategic decision to study subjects with systolic blood pressure (BP) greater than or equal to 135mmHg, as well as CKD with albuminuria.
◦The objective in Part A is to assess the effect of lorundrostat, alone or in combination with dapagliflozin in subjects with uncontrolled hypertension and stage 2-3a CKD,
on systolic BP, as well as albuminuria, a surrogate endpoint that supports long-term benefit in CKD. The Company plans to study 25mg once daily (QD) in this trial.
◦The objective in Part B is to characterize the safety and tolerability of lorundrostat in subjects with uncontrolled hypertension and stage 3b CKD with albuminuria. This open-label safety study will evaluate 12.5mg QD lorundrostat with titration to 25mg QD based on pre-specified criteria. A new key exploratory objective for Part B is to assess the effect of lorundrostat on systolic BP.
Third Quarter 2023 Financial Highlights
Cash, cash equivalents and investments were $265.9 million as of September 30, 2023, compared to $110.1 million as of December 31, 2022. The Company believes that its cash, cash equivalents and investments as of September 30, 2023 will be sufficient to allow the Company to fund its planned clinical studies, as well as support corporate operations, through mid-2025.
Research and Development (R&D) expenses were $22.5 million for the quarter ended September 30, 2023, compared to $6.1 million for the quarter ended September 30, 2022. The increase in R&D expenses was primarily due to increases of $12.4 million in preclinical and clinical costs, driven by the initiation of the lorundrostat pivotal program in 2023, $2.3 million in clinical supply, manufacturing and regulatory costs and $1.7 million in higher compensation expense resulting from additions to headcount.
General and Administrative (G&A) expenses were $3.8 million for the quarter ended September 30, 2023, compared to $1.4 million for the quarter ended September 30, 2022. The increase in G&A expenses was primarily due to $1.2 million in higher professional fees associated with operating as a public company, $0.8 million in higher compensation expense resulting from additions to headcount, $0.3 million of higher insurance expense associated with new director and officer insurance policies and $0.1 million in higher other administrative expenses.
Total other income, net was $3.5 million for the quarter ended September 30, 2023, compared to $0.7 million for the quarter ended September 30, 2022, which was primarily attributable to increased interest earned on the Company’s investments in money market funds and U.S. treasuries.
Net loss was $22.8 million for the quarter ended September 30, 2023, compared to $6.7 million for the quarter ended September 30, 2022. 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. 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.
