Mineralys Therapeutics Announces FDA Acceptance Of NDA For Lorundrostat For Treatment Of Adults With Hypertension And Reports Topline Explore-OSA Trial Results
Mineralys Therapeutics, Inc. announced that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for lorundrostat for the treatment of adult patients with hypertension in combination with other antihypertensive drugs. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of December 22, 2026. The NDA is based on positive data from a successful clinical program demonstrating favorable safety and blood pressure reduction in adults with hypertension. Topline results from the Phase 2 Explore-OSA exploratory trial did not reduce AHI; demonstrated a clinically meaningful reduction in blood pressure and favorable safety and tolerability in this population with difficult to control hypertension. The Explore-OSA trial was a Phase 2 exploratory trial of lorundrostat in forty-eight participants with an average body mass index (BMI) of 38.2 kg/m2, an average apnea-hypopnea index (AHI) of 48.5 events/hr and an average systolic blood pressure (BP) of 142.3 mmHg (range 131-175 mmHg). After four weeks of treatment, lorundrostat 50 mg dosed in the evening did not demonstrate a clinically meaningful difference relative to placebo on the apnea-hypopnea index (AHI), the primary endpoint. At week four, the trial demonstrated an 11.1 mmHg (p < 0.0001) and a 1.0 mmHg (p = NS) BP reduction with lorundrostat and placebo, respectively, in the pre-planned parallel arm analysis of the first period. There was a 6.2 mmHg placebo-adjusted reduction (p < 0.0003) in BP in the crossover analysis. Lorundrostat demonstrated a favorable safety profile and was well tolerated, with no serum potassium excursions above 5.5 mmol/L. Analysis is ongoing for other endpoints in the trial and will be reported in future publications or medical meetings. Launch-HTN (NCT06153693) was a global, randomized Phase 3 double-blind, placebo-controlled trial of adults whose blood pressure (BP) remained uncontrolled despite being on two to five antihypertensive medications. Participants were assigned to one of three groups: placebo; lorundrostat 50 mg once daily; or lorundrostat 50 mg once daily with the option to increase to 100 mg at week six. The primary endpoint was change from baseline in systolic BP at six weeks versus placebo, measured by automated office blood pressure monitoring. Advance-HTN (NCT05769608) was a randomized, double-blind, placebo-controlled Phase 2 clinical trial that evaluated the efficacy and safety of lorundrostat for the treatment of uncontrolled or resistant hypertension, when used as an add-on therapy to a standardized background treatment of two or three antihypertensive medications in adult participants. Participants who met screening criteria had their existing hypertension medications discontinued and started on a standard regimen of an angiotensin II receptor blocker (ARB) and a diuretic, if previously on two medications, or a standard regimen of ARB, diuretic and calcium channel blocker if previously on three to five medications. Participants who remained hypertensive despite the standardized regimen were then randomized into three cohorts and treated for twelve weeks: lorundrostat 50 mg once daily, lorundrostat 50 mg once daily and an option to titrate to 100 mg once daily at week four based on defined criteria, or placebo. The trial’s primary endpoint was the change in 24-hour ambulatory systolic blood pressure at week twelve from baseline for active cohorts versus placebo. The Explore-OSA trial (NCT06785454) was a Phase 2 randomized, double-blind, placebo-controlled, crossover trial. This proof-of-concept trial was designed to evaluate the efficacy, safety, and tolerability of lorundrostat in overweight or obese adults with moderate-to-severe OSA and hypertension. Participants in Explore-OSA received 50 mg of oral, once daily (QD) lorundrostat and placebo in sequential treatment periods, with continuous monitoring of BP during overnight polysomnography. The primary efficacy endpoint of the trial was absolute change from baseline in apnea-hypopnea index (AHI) after four weeks of active treatment compared to placebo. The first secondary endpoint was AOBP, and additional endpoints were nighttime BP and sleep and cardiovascular health measures. Lorundrostat is a proprietary, orally administered, highly selective aldosterone synthase inhibitor being developed for the treatment of uncontrolled hypertension (uHTN) or resistant hypertension (rHTN), as well as CKD and OSA. 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 a 40-70% reduction in plasma aldosterone concentration in hypertensive participants. The Company has now completed five successful Phase 2/3 clinical trials of lorundrostat supporting the efficacy and safety profile while also validating aldosterone as an integral therapeutic target in uHTN and rHTN. This includes two pivotal, registrational trials, including the Phase 3 Launch-HTN trial and Phase 2 Advance-HTN trial, which support the robust, durable and clinically meaningful reductions in systolic BP by lorundrostat. Lorundrostat was well tolerated in both trials with a favorable safety profile.
