Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

PentixaFor radiolabeled with 68Gallium (68Ga) is a radiopharmaceutical targeting the CXC chemokine receptor 4 (CXCR4) receptor. The CXCR4 receptor is expressed in zona glomerulosa of the adrenal cortex and in aldosterone producing adenoma (APA). The objective of this study will be to evaluate in 25 patients if \[68Ga\]Ga-PentixaFor positron emission tomography (\[68Ga\]Ga-PTF-PET) imaging allows for the discrimination of patients with lateralized or non-lateralized secretion of aldosterone in adrenal glands classified based on adrenal vein sampling (AVS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The identification of the cause of primary aldosteronism (PA) is critical because, in case of lateralized secretion of aldosterone, a surgical treatment can be offered to patients with the objective of full patient recovery, whereas in case of bilateral secretion, only a long-term medical treatment with mineralocorticoid receptor antagonists should be considered. The presence or absence of adrenal nodule on morphological imaging does not allow us to state on the lateralization or not of aldosterone secretion. Moreover, on one hand, the prevalence of adrenal incidentalomas, mostly non-secreting, can be detected in between 2 to 10% of general population. On the other hand, unilateral secretion of aldosterone exists in 30% of patients with normal adrenal glands on imaging. The AVS with measurements of the concentrations of aldosterone is the closest to a referral exam to confirm the diagnosis of lateralized secretion of aldosterone, but it is a complex and invasive procedure with only limited access to centers with expertise in invasive radiology and an important heterogeneity in interpretation. The development of noninvasive imaging approaches allowing for a more specific identification of lateralized vs. bilateral aldosterone secretion would, hence, have a major impact on the clinical management of these patients.
