Study Evaluating [18F]NOTA-ABY030 for Safety and Tolerability of Indeterminate Primary and/or Metastatic Disease in Head and Neck Squamous Cell Carcinoma

Sponsor

Vanderbilt-Ingram Cancer Center

Enrollment

25 participants

Start Date

Apr 24, 2026

Study Type

INTERVENTIONAL

Conditions

Head and Neck Squamous Cell Carcinoma Metastatic Head and Neck Squamous Cell Carcinoma SCC - Squamous Cell Carcinoma Radiotracer

Summary

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.
