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.

Exclusion Criteria:

1. Patients not eligible for SOC surgical resection
2. Active or history of autoimmune disease or immune deficiency, including, but not limited to, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, antiphospholipid antibody syndrome, Wegener granulomatosis, Sjögren syndrome, Guillain-Barré syndrome, or multiple sclerosis with the following exceptions:

   * Patients with controlled Type 1 diabetes mellitus who are on an insulin regimen are eligible for the study.
   * Patients with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only (e.g., patients with psoriatic arthritis are excluded) are eligible for the study provided if all the following conditions are met:
   * Rash must cover \< 10% of body surface area
   * Disease is well controlled at baseline and requires only low-potency topical corticosteroids
   * No occurrence of acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high-potency oral corticosteroids within the previous 12 months.
3. History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan.

   * History of radiation pneumonitis in the radiation field (fibrosis) is permitted.
4. Significant cardiovascular disease (such as New York Heart Association Class II or greater cardiac disease, myocardial infarction, or cerebrovascular accident) within 6 months prior to initiation of study treatment, unstable arrhythmia, or unstable angina
5. Severe unresolved infection within 4 weeks prior to initiation of study treatment.
6. Prior allogeneic stem cell or solid organ transplantation
7. History of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins
8. Chronic treatment with systemic immunosuppressive medication in excess of physiologic maintenance doses of corticosteroids (\>10 mg/day of prednisone or equivalent) (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF-a agents), with the following exceptions:

   * Patients who received acute, systemic immunosuppressant medication or a dose of systemic immunosuppressant medication are eligible for the study.
   * Physiologic corticosteroid replacement therapy at doses ≤ 10 mg/day of prednisone or equivalent for adrenal or pituitary insufficiency and in the absence of active autoimmune disease is permitted.
   * Patients with asthma that requires intermittent use of bronchodilators, inhaled steroids, or local steroid injections may participate.
   * Patients using topical, ocular, intra-articular, or intranasal steroids (with minimal systemic absorption) may participate.
   * Brief courses of corticosteroids for prophylaxis (e.g., contrast dye allergy) or study treatment-related standard pre-medication are permitted.
9. Pregnant or breastfeeding, or intention of becoming pregnant during study treatment or within 5 months after the final administration of study treatment.
