A Phase 2 interventional study of [68Ga]Ga-PentixaFor in Hyperaldosteronism, Hypercortisolism and Cushing s Syndrome, sponsored by National Cancer Institute (NCI). Recruiting at 1 site in United States. Open to participants aged 18 Years to 120 Years. Per ClinicalTrials.gov, last updated 2026-10-22.
Sponsored by National Cancer Institute (NCI) · Phase 2, Interventional, and Diagnostic
Background:
The adrenal glands are 2 small organs that sit on top of each kidney. They release hormones; these are chemicals that control how the body works. Tumors on or outside the adrenal glands are called functional if they release hormones; they are called nonfunctional if they do not. Doctors who treat adrenal tumors need to know which type a person has. Researchers want to find better ways to learn whether an adrenal tumor is functional.
Objective:
To see if a new radioactive tracer ([68Ga]Ga-PentixaFor) can make it easier to identify functional adrenal tumors with positron emission tomography (PET) scans.
Eligibility:
People aged 18 years and older with 1 or more adrenal tumors. They must have increased levels of the hormones aldosterone or cortisol. They must also be enrolled in at least 1 other related NIH study (protocols 19-DK-0066, 18-CH-0031, or 09-C-0242).
Design:
Participants will be screened. They may have imaging scans. Their ability to perform normal activities will be reviewed.
Participants will have one PET scan with the study tracer.
The tracer will be given through a tube attached to a needle inserted into a vein. Participants will receive the tracer 1 hour before the scan. They will lie still on a bed while a machine captures images of the inside of their body. The scan will take 45 to 90 minutes.
Participants heart rate, blood pressure, and rate of breathing will be checked before, during, and after the scan.
Participants will have a follow-up visit 3 days after their scan. This visit can be by phone, email, or in person.
Background:
Objective:
-To estimate the percent concordance of [68Ga]Ga-PentixaFor imaging with clinical diagnosis in identifying functional adrenal or extra-adrenal adenomas in hyperaldosteronism and hypercortisolism

EXCLUSION CRITERIA:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Participants will undergo \[68Ga\]Ga-PentixaFor PET/CT or PET/MR
Drug: [68Ga]Ga-PentixaFor
\[68Ga\]Ga-PentixaFor will be injected intravenously approximately 60 minutes prior to scanning at a dose of 150 +/- 50 MBq (4 mCi +/- 1.4).
Estimate the percent concordance of [68Ga]Ga-PentixaFor imaging with clinical diagnosis in identifying functional adrenal or extra-adrenal adenomas in hyperaldosteronism and hypercortisolism
The percent concordance between \[68Ga\]Ga-PentixaFor and clinical diagnosis will be estimated within each Cohort, along with 90% Clopper-Pearson confidence intervals.
Time frame: Screening
Compare [68Ga]Ga-PentixaFor uptake to C-X-C chemokine receptor type 4 (CXCR4) expression in resected tissue (when obtained on parent protocol)
The Spearman rank correlation coefficient between \[68Ga\]Ga-PentixaFor PET parameters (SUVmax, SUVmean, TLU, TV) and CXCR4 expression as measured via immunohistochemistry will be estimated within each Cohort.
Time frame: Within 1 year following [68Ga]Ga-PentixaFor imaging
Evaluate threshold values of [68Ga]Ga-PentixaFor uptake for determining adrenal mass hyperfunction
Receiver operating characteristic (ROC) curves of \[68Ga\]Ga-PentixaFor SUVmax in detecting adrenal mass hyperfunction will be constructed. The cutoff associated with the highest Youden index (sensitivity plus specificity) will be selected as the optimal threshold.
Time frame: Within 1 year following [68Ga]Ga-PentixaFor imaging
Estimate the safety of [68Ga]Ga-PentixaFor
Safety will be evaluated by determining the frequency of adverse events among participants and reporting the results, by maximum grade of event and type of toxicity noted.
Time frame: Day of [68Ga]Ga-PentixaFor administration until end of study participation
Plan to share: Yes — All IPD recorded in the medical record will be shared with intramural investigators upon request.
Supporting information: Study protocol, Statistical analysis plan, Informed consent form
