Window Trial of Fluorescently Labeled Nivolumab-IRDye800 (Nivo800) in High Grade Glioma (HGG)
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.
