NCT07217028
Study Evaluating [18F]NOTA-ABY030 for Safety and Tolerability of Indeterminate Primary and/or Metastatic Disease in Head and Neck Squamous Cell Carcinoma
This Phase I, single-institution, open-label study will evaluate the safety, tolerability, and diagnostic performance of \[18F\]NOTA-ABY030 PET/CT in patients with head and neck squamous cell carcinoma (HNSCC) who present with indeterminate lesions on standard imaging. The investigational agent is a radiolabeled anti-EGFR affibody designed for rapid clearance and improved tumor-to-background contrast. All participants will receive a 50 mg cetuximab loading dose followed by a bolus of \[18F\]NOTA-ABY030, with PET/CT imaging performed at defined intervals to assess biodistribution and lesion uptake. The primary objective is to determine safety and tolerability; secondary objectives include radiation dosimetry and comparison of sensitivity and specificity to conventional imaging modalities (MRI, CT, and \[18F\]FDG-PET/CT). This approach aims to improve diagnostic accuracy, reduce unnecessary biopsies, and streamline treatment decisions for patients with HNSCC.

Positron Emission Tomography (PET) Imaging of Cholesterol Trafficking: Clinical Evaluation of [18F]FNP-59 in Normal Human Subjects (Group 1)
This exploratory, first-in-man, phase 0 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 in healthy normal subjects. The researchers believe that \[18F\]FNP-59 would greatly improve the imaging characteristics, by providing a PET imaging cholesterol analogue with significantly improved radiation dosimetry.

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