Mineralys Therapeutics Completes Enrollment Ahead of Schedule in Launch-HTN, the Second Pivotal Trial of Lorundrostat for the Treatment of Hypertension

Mineralys Therapeutics, Inc. (Nasdaq: MLYS), a clinical-stage biopharmaceutical company focused on developing medicines to target hypertension, chronic kidney disease (CKD) and other prevalent cardiovascular diseases driven by dysregulated aldosterone, today announced that it has completed enrollment in the Launch-HTN trial ahead of schedule. Launch-HTN is the second of two trials under the planned pivotal program evaluating the efficacy and safety of lorundrostat for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN). The Company expects the trial to be completed earlier than planned, with topline data now anticipated in mid first half of 2025.

“Due to the high interest among treating physicians and patients in the Launch-HTN trial, we have completed enrollment earlier than planned. This trial is designed to model the real-world treatment of uHTN and rHTN using lorundrostat in the primary care setting,” stated David Rodman, MD, Chief Medical Officer of Mineralys Therapeutics. “We look forward to sharing the topline data from the trial, which are now expected to be available in mid first half of 2025. We greatly appreciate the enthusiasm and commitment that participating trial investigators and trial participants have shown to the development program for lorundrostat.”

The Launch-HTN trial (NCT06153693), a global, randomized, double-blinded, placebo-controlled Phase 3 trial, enrolled eligible adult participants who failed to achieve their blood pressure goal despite being on two to five background antihypertensive medications. Eligible subjects were randomized to one of 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 six. The primary endpoint of the trial is change from baseline in systolic blood pressure versus placebo after six weeks of treatment, as measured by automated office blood pressure monitoring.

This event will provide expert perspectives on the currently available treatment options for uHTN and rHTN, as well as a review of the ongoing pivotal clinical program for lorundrostat, including the Advance-HTN and Launch-HTN trials.

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 Lorundrostat

Lorundrostat is a proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uHTN 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 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.
