Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort 1 - Dosimetry (3 Whole Body PET/CT Scans)

Cohort A will include a minimum of six participants up to 12 participants. These participants will receive a 50 mg intravenous infusion of cetuximab, followed by a bolus injection of \[18F\]NOTA-ABY-030 at a dose of 5 (±1) mCi. To evaluate tracer distribution and radiation exposure, participants in this cohort will undergo three whole-body PET/CT scans at specific timepoints: 0-90 minutes, 120 minutes, and 240 minutes post-injection. Each scan will cover the region from the skull to mid-thigh, with a total imaging time of approximately 90 minutes. This cohort is essential for determining the absorbed dose, organ-specific uptake, identification of critical organs, and the effective dose of the radiopharmaceutical. The data collected from Cohort A will inform safety parameters and support dose optimization for future clinical studies involving \[18F\]NOTA-ABY-030.

Cohort 2 - (1 Whole Body PET/CT Scan)

Cohort 2 will include 54 participants. Each participant will receive a 50 mg intravenous infusion of cetuximab, followed by a bolus injection of \[18F\]NOTA-ABY-030 at a dose of 5 (±1) mCi. Imaging for this cohort will be conducted at a single timepoint, approximately 0-240 minutes (±15 minutes) post-injection, based on optimized timing derived from Cohort 1 data. The PET/CT scan for Cohort 2 will cover the region from skull to chest, with a total scan time of approximately 30 minutes. This cohort is designed to evaluate the diagnostic performance of \[18F\]NOTA-ABY-030 in identifying indeterminate metastatic and/or primary lesions in head and neck squamous cell carcinoma (HNSCC), with a focus on sensitivity, specificity, and feasibility of the imaging protocol in a broader patient population.
