Intratumoral fluorescent nivolumab before surgery in head and neck cancer
Official title: Window Trial of Intratumoral (IT) Neoadjuvant Fluorescently Labelled Nivolumab (nivo800) in Head and Neck Squamous Cell Carcinoma (HNSCC)
Run by Vanderbilt-Ingram Cancer Center · NCT07741565 · Data updated 2026-11-12
This study tests injecting fluorescently labeled nivolumab directly into head and neck tumors to see if it is safe and whether it reaches nearby lymph nodes before surgical removal.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with biopsy-confirmed head and neck squamous cell carcinoma who are scheduled for surgical tumor removal and have adequate organ function.
✕Probably not a fit
Patients who do not derive a measurable distribution or immune response benefit from this intratumoral approach, or who experience adverse events that require study discontinuation.

What this trial studies
This early-phase trial investigates the safety and distribution of intratumorally injected nivo800 (fluorescently labeled nivolumab) in adults with head and neck squamous cell carcinoma who are planned for tumor resection. Participants receive two injections into the tumor spaced about a week or two apart, with monitoring for safety and tolerability. The study also aims to understand how much of the drug travels to adjacent lymph nodes and how delivery relates to tumor and immune responses. Outcomes include basic safety data and exploratory information on immune activity in the tumor vicinity. The trial is conducted at Vanderbilt University Medical Center under an investigator-initiated framework with the lead sponsor as Vanderbilt-Ingram Cancer Center.
Why it matters
Potential benefit: Potentially improved understanding of how immunotherapy delivered directly into tumors could guide future treatments and surgical planning.
How similar studies have gone: Prior similar approaches with intratumoral immunotherapy and fluorescent labeling have provided safety data and feasibility signals in other cancers, but this exact nivo800 intratumoral strategy in HNSCC is exploratory.

Pregnant or breastfeeding, or intention of becoming pregnant during study treatment or within 5 months after the final administration of study treatment.
