Safety and Feasibility of Nivolumab-IRDye800CW in Patients With Head and Neck Squamous Cell Carcinoma (HNSCC)

March 4, 2026 updated by: Eben Rosenthal, Vanderbilt-Ingram Cancer Center
This is a phase 1, open-label, single-center study that plans to enroll 40 participants who will undergo surgical resection as SOC for HNSCC. This trial is designed to evaluate the safety of the safety of fluorescently labeled nivolumab (nivo800) as a molecular imaging agent. The study employs a dose-escalation design across four cohorts of 10 participants each. Participants in Cohorts 1-3 will receive an infusion of nivo followed by an infusion of nivo800 prior to standard-of-care surgical resection. The administration of unlabeled nivo will be administered approximately 2-3 weeks before surgery, followed by an administration of nivo800 administered 1-2 days prior to surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
