These data, highlighted in top-tier medical forums and journals, underpin the upcoming NDA submission. Additional pipeline progress included enrollment completion in the EXPLORE-CKD trial and initiation of the EXPLORE-OSA trial, targeting high unmet need subpopulations.

• R&D Investment Surge: Clinical trial expansion and headcount increases signal commitment to broad label and specialty indications.
• Cash Runway Secured: The $343 million cash position funds operations into 2027, de-risking near-term development.
• Pivotal Data Validated: Double-digit systolic BP reductions and favorable safety profile set lorundrastat apart in late-line hypertension.

Mineralis’ financials reflect a company in transition from late-stage development to regulatory engagement and eventual commercialization, with resource allocation tightly aligned to clinical and market access strategy.

Executive Commentary

Strategic Positioning

1. Lorundrastat: Pivotal Data as Regulatory Foundation

Both LAUNCH-HTN and ADVANCE-HTN trials demonstrated statistically significant, clinically meaningful reductions in systolic blood pressure—with placebo-adjusted reductions exceeding 7.9 mmHg in the most refractory populations. The safety profile, particularly the low incidence of moderate or severe hyperkalemia, compares favorably to legacy mineralocorticoid receptor antagonists and other aldosterone synthase inhibitors. These results, highlighted in the New England Journal of Medicine and major cardiology conferences, anchor the NDA package and differentiate lorundrastat as a late-line antihypertensive with broad applicability.

2. Commercialization Readiness: Physician Demand and Organizational Buildout

Mineralis is actively preparing for commercialization with the appointment of a seasoned Chief Commercial Officer and physician intent data showing 95% of surveyed clinicians would prescribe lorundrastat if approved. The company’s IQVIA analysis identified a core target of 47,000 prescribers accounting for half of late-line hypertension scripts, supporting a focused launch model. Early commercial strategy emphasizes targeting third- and fourth-line therapy positions where unmet need is highest.

3. Pipeline Expansion: Addressing Adjacent High-Need Indications

Ongoing proof-of-concept trials in chronic kidney disease (CKD) and obstructive sleep apnea (OSA) extend lorundrastat’s potential beyond hypertension. EXPLORE-CKD is designed to inform safety and efficacy in patients with eGFR as low as 30, a key population for label expansion. The OSA trial will provide the first data on nighttime hypertension control and apnea-hypopnea index impact, targeting a comorbidity with limited current treatment options. These studies support a strategy of broadening addressable markets and deepening the clinical value proposition for payers and prescribers.

4. Partnership and Global Strategy: U.S. and Ex-U.S. Leverage

Mineralis is pursuing ex-U.S. partnerships and is open to U.S. co-commercialization to maximize lorundrastat’s reach. The company has no plans for standalone ex-U.S. operations, instead seeking partners with established infrastructure. Management highlighted ongoing but undisclosed partnership discussions, with decisions likely influenced by the outcome of the FDA pre-NDA meeting and additional data readouts.

5. Regulatory Pathway and NDA Submission Timing

The NDA will include data from LAUNCH-HTN, ADVANCE-HTN, TARGET, the open-label extension, and EXPLORE-CKD. A pre-NDA meeting with the FDA is scheduled for Q4 2025, with NDA submission timing contingent on completion of long-term safety follow-up. This regulatory engagement is a critical gating factor for both approval and commercial launch planning.

Key Considerations

Mineralis’ Q1 signals a transition from clinical development to regulatory and commercial execution, with multiple strategic levers in play.

Key Considerations:

• Late-Line Hypertension Opportunity: Lorundrastat’s efficacy and safety profile positions it as a differentiated option for uncontrolled and resistant hypertension, where current therapies are underutilized or insufficient.
• Label Expansion Potential: Data from CKD and OSA trials could support future sNDAs (supplemental new drug applications), increasing addressable patient populations.
• Commercial Model Efficiency: Targeting 47,000 high-volume prescribers enables a lean launch while maximizing early impact in the U.S. market.
• Partnership Optionality: Flexibility in commercial and development partnerships, especially ex-U.S., supports global value realization without heavy fixed-cost buildout.
• Regulatory Gatekeeping: Timing and content of the NDA, especially long-term safety data, will determine the launch window and label breadth.

Risks

Key risks include regulatory uncertainty around the NDA package, particularly the sufficiency of long-term safety data and inclusion of special populations like CKD or OSA. Market uptake may hinge on hypertension guideline updates and payer acceptance. Competition from other aldosterone synthase inhibitors or emerging antihypertensive modalities, and the ability to manage hyperkalemia risks in real-world CKD patients, could also impact adoption. Execution risk remains around commercial buildout and partnership negotiations, especially if key milestones slip.

Forward Outlook

For Q2 2025, Mineralis expects:

• Top-line data from the EXPLORE-CKD trial in late Q2.
• Ongoing enrollment and data development for the EXPLORE-OSA trial.

For full-year 2025, management plans:

• Pre-NDA meeting with the FDA in Q4 to define NDA content and timing.
• Continued commercial readiness, including engagement with potential partners.

Management noted that the timing of NDA submission will be finalized after the pre-NDA meeting and sufficient long-term safety data accrual. Physician education, payer engagement, and guideline integration will be ongoing priorities.

• EXPLORE-CKD data readout is a near-term catalyst for label expansion discussions.
• Commercial and regulatory partnership updates expected as data matures and regulatory path clarifies.

Takeaways

Mineralis’ Q1 2025 marks a strategic inflection as lorundrastat’s clinical, regulatory, and commercial foundations come into focus.

• Pivotal Data Validates Mechanism: Robust reductions in systolic blood pressure and favorable safety profile differentiate lorundrastat in a crowded late-line hypertension field.
