About this trial

The goal of this project is to improve the diagnostic pathway for patients with primary aldosteronism, by validating non-invasive biomarkers coupled with routine computed tomography imaging. The aim is to reduce reliance on invasive procedures, shorten diagnostic timelines, and enhance accessibility to definitive diagnosis and treatment globally.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Confirmed diagnosis of primary aldosteronism according to the Endocrine Society guideline 2025.

Willing to undergo subtype testing with adrenal vein sampling and/or molecular imaging (Positron Emission Tomography/Computed Tomography, PET/CT).

Keen for surgical treatment if shown to have unilateral primary aldosteronism.

Disqualifiers

Inability to provide written informed consent.

Trial design

Design model

Single group

Treatments tested in this trial

  • Hybrid hormones

    Diagnostic test

    Participants will have a baseline blood sample taken so the investigators can measure the adrenal steroid biomarkers 18-oxocortisol, 18-hydroxylcortisol and other steroids. The collected plasma or serum will then be analyzed in the laboratory using validated methods, such as liquid chromatography-tandem mass spectrometry (LC-MS/MS), to determine the levels of these biomarkers.

Trial outcomes

Primary outcomes

1

Proportion of participants with complete biochemical success after unilateral adrenalectomy for unilateral primary aldosteronism using Primary Aldosteronism Surgical Outcome (PASO) measured at least six months post-adrenalectomy.

Proportion of participants with correction of hypokalaemia and normalisation of aldosterone-renin-ratio following unilateral adrenalectomy, as per PASO criteria.

Time frame
6 months
2

Proportion of participants with KCNJ5-mutant aldosterone producing adenoma/nodule

Proportion of participants with histopathology and genetic confirmation of KCNJ5-mutant aldosterone producing adenoma/nodule in resected adrenals.

Time frame
6 months

Secondary outcomes

1

Proportion of participants with complete clinical success after unilateral adrenalectomy for unilateral primary aldosteronism using Primary Aldosteronism Surgical Outcome (PASO) measured at least six months post-adrenalectomy.

Proportion of participants with reduction in blood pressure and reduction anti-hypertensive medication following unilateral adrenalectomy, as per PASO criteria.

Time frame
6 months
2

Cost-effectiveness of using hybrid hormones coupled with computed tomography imaging versus other subtyping tests including adrenal vein sampling and/or molecular imaging in diagnosing participants with unilateral primary aldosteronism

Cost-effectiveness of the diagnostic course will be calculated by using calculated costs per quality-adjusted life years (QALYs)

Time frame
6 months
3

Diagnostic criteria using hybrid hormones/ steroid profiling coupled with computed tomography imaging

The criteria of hybrid hormones/ steroid profiling coupled with computed tomography imaging which offer the best sensitivity and specificity for lateralization of aldosterone-producing adenoma.

Time frame
6 months
