At DAMIAN, we want to help patients by creating something tangible. We focus our expertise on the diagnosis, localization and treatment of aldosterone-dependent conditions.

Identified in 1956, Primary Aldosteronism is a hormonal disorder that produces significant negative outcomes and has no targeted treatment. DAMIAN aims to change that.

The Disease

The adrenal glands help maintain blood pressure and organ perfusion through the controlled secretion of the hormone aldosterone. Primary Aldosteronism (PA) is a disorder that occurs when adrenal production of aldosterone is no longer controlled. This overproduction of aldosterone leads to water and sodium retention and potassium loss. This can result in irreversible structural damage to the blood vessels and manifest as chronic high blood pressure. Untreated, PA can lead to an increased risk of stroke, myocardial infarction, and chronic kidney disease.

dexfadrostat phosphate (DP13): Our Investigational Drug

The aldosterone synthase inhibitor dexfadrostat phosphate (DP13) is a first-of-its-kind treatment for primary aldosteronism (PA) that medically targets the cause of the disease. DAMIAN successfully completed its Phase I Clinical Trial evaluating the pharmacological properties of dexfadrostat phosphate in healthy volunteers. The safety and efficacy of dexfadrostat phosphate was investigated across Europe in a Phase II Trial, becoming the first clinical trial to demonstrate clinical efficacy in patients with PA without raising safety concerns.

Currently available therapies have no impact on the cause of PA i.e., the overproduction of aldosterone. In contrast, dexfadrostat phosphate selectively inhibits the enzyme responsible for aldosterone production, thus directly reducing the amount of aldosterone in the body. 

DP14: Our Diagnostic Tool

The diagnostic pathway for PA is complex, requiring specialist expertise, particularly the detection of a unilateral tumor which is not always successful. The introduction of DP14, a unique PET tracer currently in the research phase, has the potential to image and localize aldosterone-producing benign tumors without the need for specialist surgery and with a higher success rate. 

Future Directions

DAMIAN is committed to helping patients by finding treatment solutions wherever they exist. Remaining true to its mission, DAMIAN continues to identify and evaluate additional therapeutic opportunities or diagnostic solutions in other aldosterone-dependent conditions.

It’s not like we are searching for something theoretical. We are convinced something is there. We just need to go and prove it.

    DAMIAN announces publication of phase 2 data of dexfadrostat phosphate in patients with primary aldosteronism

    A new open-access publication

    DAMIAN announces online publication of the primary data from clinical study DP13C201 in eClinical Medicine, a Lancet journal. The clinical phase 2 study assessed whether dexfadrostat phosphate, a novel aldosterone synthase inhibitor taken orally once a day for 8 weeks, could provide biochemical and clinical benefit in patients with primary aldosteronism (PA) diagnosed, according to the Endocrine Society Clinical Practice Guidelines. The study also evaluated the effect of dexfadrostat phosphate on ambulatory diastolic blood pressure, office systolic and diastolic blood pressure, serum potassium and urinary aldosterone content as well as cortisol levels.

    Structural and clinical characterization of CYP11B2 inhibition by dexfadrostat phosphate

    A new open-access publication

    The final three steps of the biosynthetic pathway of aldosterone are catalyzed by CYP11B2, also known as aldosterone synthase. Hence, inhibiting aldosterone synthase is a targeted mechanism for new therapeutic compounds aimed at reducing aldosterone production. In a new publication by Pignatti et al. the authors reveal that the novel aldosterone synthase inhibitor, dexfadrostat phosphate, aligns with the catalytic moiety of CYP11B2 but not CYP11B1, a related enzyme in the biosynthetic pathway of cortisol. Additionally, both in vitro and clinically, dexfadrostat phosphate demonstrated significant inhibition of CYP11B2 vs. CYP11B1 and did not change basal cortisol levels. Importantly, dexfadrostat phosphate inhibits the final steps in aldosterone biosynthesis, leading to dose-dependent reductions in aldosterone in healthy volunteers.

    DAMIAN announces publication in the British Journal of Clinical Pharmacology of phase 1 data of dexfadrostat phosphate in healthy volunteers

    Today DAMIAN announces the publication of study DP13C101, a phase 1 study evaluating the efficacy and safety of dexfadrostat phosphate in healthy volunteers in the British Journal of Clinical Pharmacology.

    Dexfadrostat phosphate is a novel aldosterone synthase inhibitor (ASI), which acts to directly control the production of aldosterone at its origin. “By inhibiting the 3 enzymatic conversions mediated by aldosterone synthase, dexfadrostat phosphate was shown to demonstrate a dose-dependent reduction of the aldosterone-to-renin ratio (ARR, a marker of sodium retention) without affecting the adrenal stress response or the hypothalamic-pituitary-gonadal axis.”

    DAMIAN announced in October 2022 the successful completion of a phase 2 study evaluating dexfadrostat phosphate in patients with primary aldosteronism. The study met both its primary endpoints (ARR, ambulatory systolic blood pressure reduction) with high statistical significance following 8 weeks of once-daily treatment. The study also demonstrated a good safety and tolerability profile.

    DAMIAN announces dexfadrostat phosphate achieves high efficacy in PA patients

    DAMIAN announces new data from the Phase II trial in patients with primary aldosteronism (PA), that showed the investigational compound dexfadrostat phosphate effectively reduced both aldosterone-to-renin ratio (ARR) and ambulatory systolic blood pressure (aSBP). The trial met both primary endpoints with high significance.
