Item 8.01. Other Events.
On May 2, 2023, Mineralys Therapeutics, Inc. (the “Company”), announced the first patient dosed in the ADVANCE-HTN pivotal trial to evaluate the safety and efficacy of lorundrostat for the treatment of uncontrolled hypertension (uHTN) and resistant hypertension (rHTN) when used as an add-on therapy to standardized background treatment of two or three antihypertensive medications. The topline data from this trial are expected in the first half of 2024.
The randomized, double-blind, placebo-controlled ADVANCE-HTN trial will enroll up to approximately 300 eligible adult participants who will be randomized to three arms: placebo, lorundrostat 50 mg once daily (QD), and lorundrostat 50 mg QD and then titrated to 100 mg QD, as needed, at week four. The primary endpoint of the trial is change in systolic blood pressure versus placebo after 12 weeks of treatment, as measured by 24-hour ambulatory blood pressure monitoring.
This is the first of two clinical trials under the planned pivotal program to evaluate the safety and efficacy of lorundrostat for the treatment of uHTN and rHTN. The second pivotal trial, a Phase 3 trial in a larger population of uHTN and rHTN subjects, is expected to begin enrolling in the second half of 2023, with data anticipated in mid-2025. Patients from both studies will be offered the opportunity to participate in an open label extension trial after completion of these trials. In addition, 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 in mid-2023. Topline data from the CKD trial is expected in the first half of 2024.
Uncontrolled and resistant hypertension represent a significant unmet need within the approximately 115 million patients in the U.S. who have high blood pressure. More than half of hypertensive patients fail to achieve their blood pressure goals despite treatment, and approximately 20 million treated patients have systolic blood pressure greater than 140 mmHg.
In November 2022, the Company presented results of its Target-HTN Phase 2 trial demonstrating that lorundrostat lowered the systolic blood pressure of patients with uHTN and rHTN at a clinically meaningful and statistically significant level, with a mean placebo-adjusted reduction in systolic blood pressure of 9.6 mmHg and 7.8 mmHg with a 50 mg or 100 mg QD dose, respectively. Additionally, treatment with lorundrostat demonstrated a robust effect in obese patients, who, studies show, tend to have abnormal aldosterone biology. The Company believes the approach of reducing aldosterone production can provide an effective, targeted approach for the control of hypertension, especially in the rapidly growing subset of hypertensive individuals with obesity.
Forward-Looking Statements
The Company cautions you that statements contained in this report regarding matters that are not historical facts are forward-looking statements. The forward-looking statements are based on our current beliefs and expectations and include, but are not limited to, statements regarding: the potential therapeutic benefits of lorundrostat; the planned future clinical development of lorundrostat and the timing thereof; and expected timing of topline results from clinical trials. Actual results may differ from those set forth in this report due to the risks and uncertainties inherent in our business, including, without limitation: our future performance is dependent entirely on the success of lorundrostat; potential delays in the commencement, enrollment, and completion of clinical trials and nonclinical studies; our dependence on third parties in connection with manufacturing, research and clinical and nonclinical testing; unexpected adverse side effects or inadequate efficacy of lorundrostat that may limit its development, regulatory approval, and/or commercialization; unfavorable results from clinical trials and nonclinical studies; results of prior clinical trials and studies of lorundrostat are not necessarily predictive of future results; regulatory developments in the United States and foreign countries; our reliance on our exclusive license with Mitsubishi Tanabe to provide us with intellectual property rights to develop and commercialize lorundrostat; and other risks described in our filings with the Securities and Exchange Commission (SEC), including under the heading “Risk Factors” in our annual report on Form 10-K, and any subsequent filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and we undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date hereof. All forward-looking statements are qualified in their entirety by this cautionary statement, which is made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
