    Positron Emission Tomography (PET) Imaging of Cholesterol Trafficking: Clinical Evaluation of [18F]FNP-59 in Normal Human Subjects (Groups 2, 3 & 4)

    NCT04546126

Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

This study will evaluate the feasibility of using a sub-therapeutic dose of a fluorine-18 analogue of NP-59 (\[18F\]FNP-59) to image the adrenal gland. Some participants are healthy normal subjects but have undergone interventions to manipulate hormones while other participants have known adrenal pathology.

Interventions

  • Dexamethasone (Group 2)Drug
  • Cosyntropin (Group 3)Drug
  • PET/CT Scan with FNP-59Combination product

Arms3

  • Experimental

    Dexamethasone (Group 2)

    Participants will undergo an FNP-59 scan on day 0 in the am. Participants will then take 1 mg dexamethasone 2x a day for 3 days to suppress cortisol production. Participants will then have a second FNP-59 scan on day 4 in the am.

  • Experimental

    Cosyntropin (Group 3)

    Participants will undergo an FNP-59 scan on day 0 in the am. On day 4 the participant will arrive for imaging. Cosyntropin, 250 micro-gm will be administered IV. Five minutes following administration FNP-59 will be given. Following uptake of FNP-59 imaging will occur.

  • Experimental

    Adrenal pathology (Group 4)

    Whole-body PET/CT scans will be done on 4 patients at 1 hr and the other 4 patients at 6 hours. All the patients will have a whole-body PET/CT scan at 3 hours.

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. Change in [18F]FNP-59 chemistry uptake as measured by the standardized uptake value (SUV) based gland segmentation

    Time frame · Day 0, Day 4

    Registry description

    SUV will be reported. Both maximal and average SUVs will be calculated

Secondary outcomes(1)
  1. PET/CT image uptake score as measured by investigator visual assessment for each volume of interest (VOI)

    Time frame · Day 4

    Registry description

    Investigator scoring system (no increased uptake = 0, mild uptake = 1, moderate uptake = 2, high uptake = 3, relative to background. Higher scores indicate increased uptake.
