The main questions it aims to answer are:\n\n* What are the uptake characteristics of \\[18F\\]CETO in adrenal tissue in patients with primary aldosteronism?\n* What is the concordance between the adrenal vein sampling and the \\[18F\\]CETO PET/CT scan results?\n* What is the effect of adrenal perfusion on \\[18F\\]CETO uptake in the adrenal glands?\n\nResearchers will compare the results of the adrenal vein sampling to a \\[18F\\]CETO PET/CT scan to see if the PET/CT can accurately identify the subtypes of primary aldosteronism. Participants will:\n\n* Take dexamethasone three days prior to the scan\n* Undergo a \\[18F\\]CETO PET/CT\n* Report burden of pre-treatment and PET/CT scan", "detailedDescription"=>"Rationale Primary aldosteronism (PA) is a relatively frequent and clinically relevant secondary cause of hypertension. PA is usually caused by either an aldosterone producing adrenal adenoma (APA) or bilateral adrenal hyperplasia (BAH). Differentiation between these two subtypes is important as it determines the treatment of choice, i.e., unilateral adrenalectomy in case of APA and medical treatment with a mineralocorticoid receptor antagonist in case of BAH. Adrenal vein sampling (AVS) is considered the optimal diagnostic test for this subtyping and is recommended in most patients with PA who are a candidate for surgery. AVS, however, is an invasive and time-consuming procedure with limited availability due to the special expertise required. Additional disadvantages are the risk of procedure related complications and the relative high costs. Thus, there is an unmet need for a non-invasive, faster, more patient friendly and less expensive diagnostic test which can distinguish between the two main subtypes of PA. PET/CT with para-chloro-2-\\[18F\\]fluoroethyl-etomidate (\\[18F\\]CETO) has a high specificity for the steroidogenic enzymes CYP11B1 and CYP11B2, present in the adrenal cortex, and has more favourable tracer characteristics compared to \\[11C\\]metomidate. Results obtained with this novel tracer seem promising, but its potential value in the subtyping of PA needs to be further established. Our hypothesis is that \\[18F\\]CETO PET/CT is selectively taken up by aldosterone producing adrenal tissue.\n\nObjective The main objective is to investigate the uptake characteristics of \\[18F\\]CETO in adrenal tissue in patients with either APA or BAH. The secondary objective is to evaluate the concordance between the results of adrenal vein sampling and the results of the \\[18F\\]CETO scan. In addition, the effect of tissue perfusion on the \\[18F\\]CETO uptake by means of a 15O water scan is studied.\n\nMain trial endpoints The main trial endpoint is the investigation of \\[18F\\]CETO uptake by adrenal gland tissue in patients with either APA or BAH. Descriptive statistics will be used to explore uptake characteristics.\n\nSecondary trial endpoints The secondary trial end points are i) the concordance between the results of adrenal vein sampling and ii) the relationship between adrenal perfusion and \\[18F\\]CETO uptake Trial design Prospective, single-center, diagnostic, observational pilot study. The expected duration of this study is 2 years.\n\nTrial population Adult patients \\> 18 years of age with biochemically confirmed PA who underwent a successful AVS (n=12) are eligible for inclusion. Main exclusion criteria are diabetes mellitus, serious comorbidity precluding surgery and use of specific medications.\n\nInterventions Participating patients have been subjected to the routine diagnostic work-up for PA as recommended by the guideline of the European Society of Hypertension (2020), including hormonal evaluation before and after a salt-loading protocol, CT or MRI of the adrenal glands and AVS. Three days prior to the PET/CT scans, patients receive pretreatment with dexamethasone in order to enhance tracer specificity. Each participant will be subjected to one additional hospital visit for the investigational diagnostic PET-CT procedure with the administration of \\[18F\\]CETO, which is directly preceded by a 15O water scan.\n\nEthical considerations relating to the clinical trial including the expected benefit to the individual subject or group of patients represented by the trial subjects as well as the nature and extent of burden and risks.\n\nNo adverse effects following \\[18F\\]CETO and 15O water injection have been reported in the literature. Pretreatment with dexamethasone is recommended for the \\[18F\\]CETO PET/CT and could result in mild reversible side effects (hyperglycemia, mood changes, sleep disturbance), which will be monitored by means of a non-invasive questionnaire. As this is a diagnostic pilot study, participating patients will not benefit directly from this investigational diagnostic procedure. However, patients contribute to gathering information on the application of \\[18F\\]CETO PET/CT, potentially reducing the need for AVS in future patients."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\n* above 18 years\n* Biochemically established diagnosis of PA\\*\n* Completion of standard diagnostic work-up of PA\\*\n* Able to follow and understand instructions to participate in the study\n* Able to give written informed consent.\n\nExclusion Criteria:\n\n* diabetes mellitus (i.e., HbA1c above 42 mmol/mol, and/or fasting plasma glucose \\> 7.0 mol/l or non-fasting plasma glucose above 11.1 mmol/L )\n* serious comorbidities precluding surgery\n* severe claustrophobia\n* pregnancy/breastfeeding or unable/unwilling to take adequate contraceptives (female only)\n* concurrent active infections (e.g., viral, fungal or parasite infections)\\*\\*\n* problematic venous access\n* unable/unwilling to take dexamethasone prior to \\[18F\\]CETO scanning\n* inability to temporary stop medication affecting aldosterone secretion\n* use of ketoconazole, metyrapone or cytostatic drugs during previous 6 months\\*\\*\\*\n* long-term use of prednisolone and/or dexamethasone."}, "identificationModule"=>{"nctId"=>"NCT06616142", "acronym"=>"SPACE", "briefTitle"=>"Subtyping Primary Aldosteronism with Para-chloro-2-[18F]fluoroethyl-etomidate", "organization"=>{"class"=>"OTHER", "fullName"=>"University Medical Center Groningen"}, "officialTitle"=>"Para-chloro-2-[18F]fluoroethyl-etomidate ([18F]CETO) As a New PET-tracer for Subtyping in Patients with Primary Aldosteronism - a Pilot Study", "orgStudyIdInfo"=>{"id"=>"SPACE 2024/176"}, "secondaryIdInfos"=>[{"id"=>"2023-508254-26-00", "type"=>"CTIS"}]}, "armsInterventionsModule"=>{"armGroups"=>[{"type"=>"ACTIVE_COMPARATOR", "label"=>"Aldosterone producing adenoma", "description"=>"Patients diagnosed with an aldosterone producing adenoma", "interventionNames"=>["Drug: [18F]CETO tracer", "Drug: Dexamethasone oral", "Procedure: Adrenal vein sampling"]}, {"type"=>"ACTIVE_COMPARATOR", "label"=>"Bilateral adrenal hyperplasia", "description"=>"Patients diagnosed with bilateral adrenal hyperplasia", "interventionNames"=>["Drug: [18F]CETO tracer", "Drug: Dexamethasone oral", "Procedure: Adrenal vein sampling"]}], "interventions"=>[{"name"=>"[18F]CETO tracer", "type"=>"DRUG", "otherNames"=>["Para-chloro-2-[18F]fluoroethyl-etomidate ([18F]CETO)"], "description"=>"PET/CT with para-chloro-2-\\[18F\\]fluoroethyl-etomidate (\\[18F\\]CETO) has a high specificity for the steroidogenic enzymes CYP11B1 and CYP11B2, present in the adrenal cortex, and has more favourable tracer characteristics compared to \\[11C\\]metomidate.
