Flurpiridaz F-18 PET/CT to Find Parathyroid Adenomas

Official title: Flurpiridaz F-18 PET/CT Imaging for Detecting Parathyroid Adenomas in Patients With Primary Hyperparathyroidism

Run by University of Pennsylvania · NCT07910097 · Data updated 2026-11-12

This study tests whether Flurpiridaz F-18 PET/CT can better detect abnormal parathyroid glands in adults with primary hyperparathyroidism before surgery.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with known or suspected parathyroid adenomas and planned parathyroid surgery, who have had or will have prior SPECT/CT sestamibi imaging.

Probably not a fit

Patients without detectable differences in imaging performance or those not undergoing surgery within six months may not benefit.

What this trial studies

This early-phase study compares Flurpiridaz F-18 PET/CT to the standard SPECT/CT imaging for identifying parathyroid adenomas in adults with primary hyperparathyroidism. Participants will have prior SPECT/CT imaging and planned parathyroid surgery within six months, and will receive Flurpiridaz F-18 PET/CT to assess diagnostic performance. The trial focuses on imaging accuracy to guide surgical planning. Outcomes will inform whether the new PET/CT approach offers improved localization over current imaging. Safety and feasibility of the imaging modality will also be monitored.

Why it matters

Potential benefit: If successful, Flurpiridaz F-18 PET/CT could improve accuracy of locating diseased parathyroid tissue, potentially guiding more precise surgery.

How similar studies have gone: Previous imaging approaches with PET/CT have shown promise in localizing parathyroid tissue, but this exact fluorine-18 tracer approach is being explored for its diagnostic performance.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Adult patients, at least 18 years of age
2. History of primary hyperparathyroidism as clinically confirmed by serum laboratory values of elevated calcium levels (\>10.2 mg/dl) and abnormal or inappropriately normal parathyroid hormone concentrations (normal range: 15 to 65 pg/ml).
3. Participants must be informed of the investigational nature of this study and provide written informed consent in accordance with institutional and federal guidelines prior to study-specific procedures.
4. Participants must have had prior SPECT/CT sestamibi parathyroid imaging within 6 months of this investigational study or planned SPECT/CT sestamibi parathyroid imaging scheduled prior to this investigational study.
5. Planned surgery within 6 months following this investigational study.

Exclusion Criteria:

1. Females who are pregnant or breast feeding at the time of the PET/CT scan will not be eligible for this study; a urine pregnancy test will be performed in women of child-bearing potential ( as self-reported by menstrual history) before the injection of radiotracer.
2. Inability to tolerate imaging procedures, including but not limited to claustrophobia, inability to remain still during scanning, or any other condition that, in the judgment of the investigator or treating physician, would interfere with safe or adequate imaging.
3. Serious or unstable medical or psychological conditions that, in the opinion of the investigator would compromise the subject's safety or successful participation in the study.
