Comparing two methods for assessing primary aldosteronism outcomes

68Ga-Pentixafor PET/CT Versus Adrenal Vein Sampling to Determine Treatment in Primary Aldosteronism: A Multicenter Randomized Clinical Trial

Not applicable Interventional Chongqing Medical University · NCT06238232

This study is testing whether a new imaging method or a traditional sampling method is better for helping people with primary aldosteronism and adrenal nodules to manage their condition over the long term.

What this trial studies

This study aims to compare the effectiveness of 68Ga-Pentixafor PET/CT versus adrenal vein sampling (AVS) in determining long-term outcomes for patients with primary aldosteronism who have adrenal nodules of 1 cm or larger. A total of 320 patients will be randomly assigned to either the PET/CT intervention group or the AVS control group. The study will evaluate which method provides better long-term results for managing primary aldosteronism. Participants must meet specific criteria related to their condition and willingness to undergo surgery.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18-70 with primary aldosteronism and adrenal nodules of at least 1 cm who are willing to undergo surgery.

Not a fit: Patients with conditions such as autonomous cortisol secretion, familial hyperaldosteronism, or those with a history of adrenalectomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and treatment strategies for patients with primary aldosteronism.

How similar studies have performed: While there have been studies on adrenal vein sampling, the use of 68Ga-Pentixafor PET/CT in this context is relatively novel and has not been extensively tested.
