NCT07210632

Brief Summary

High-grade gliomas (HGGs) are among the most aggressive and treatment-resistant brain tumors. Immunotherapy with checkpoint inhibitors like nivolumab has shown promise, but its efficacy remains variable and poorly understood in this patient population. This clinical trial investigates a novel imaging-enabled formulation of nivolumab-IRDye800 (nivo800) which incorporates a near-infrared (NIR) fluorescent dye to enable real-time visualization of drug distribution within tumor tissue.

Outcome Measures

Primary Outcomes (1)

  • Determine the safety of fluorescently labeled nivolumab-IRDye800 (nivo800) as a molecular imaging agent via assessing adverse events.

    As defined by the number of Grade ≥ 2 Adverse Events (AEs) determined that are clinically significant and considered definitely or probably related to nivo800. Safety data will be summarized by grade, severity, and type.

    From infusion to 15 days post-infusion.

Secondary Outcomes (1)

  • Determine the optimal dose of nivolumab-IRDye800 (nivo800) for near-infrared (NIR) fluorescence imaging in the tumor, via microscopic imaging.

    From Day of Surgery Resection to 3 months

Interventions

Participants will receive an infusion of nivolumab-IRDye800 (nivo800). Nivo800 has never been assessed in patients before and therefore Cohort 1 will receive only a test dose to determine the safety (3 participants). Cohorts 2-4 will receive escalating doses of nivo800, keeping the overall dose nivolumab + nivo800 no more than 240 mg. Participants will undergo planned Standard of Care surgical resection at 1-4 days after infusion.

Participants will receive a single infusion of nivolumab following an infusion of nivolumab-IRDye800 (nivo800), for a combined total dose of 240 mg. This dosing applies to all cohorts except Cohort 1, which is designated as the safety group. Each cohort, other than Cohort 1, will receive no more than 240 mg in total of nivolumab and nivo800 combined. Participants will then undergo planned Standard of Care (SOC) surgical resection 1 to 4 days after the infusion.
