First Human Use of the CIPHER System for Brain Surgery in Adults with Newly Diagnosed Glioma Evaluating Safety and Function During Tumor Removal Surgery

What this Trial Is About

Researchers are evaluating the CIPHER System in patients undergoing brain tumor removal surgery for newly diagnosed supratentorial glioma. This First-in-Human clinical investigation aims to assess the safety and basic performance of a novel, highly flexible, electrode-dense cortical probe designed for neurophysiological mapping and stimulation during brain tumor resection. The study focuses on how well the device functions and its handling characteristics during short-term use in surgery. Participants will have the CIPHER Probe placed on the surface of the brain during standard tumor removal surgery. Two groups are studied one where only neural activity is recorded and another where both recording and electrical stimulation are performed using the probe. No stimulation is delivered in the recording-only group. The device is tested on the main tumor area and the surrounding tissue margin just before tumor removal. During the study, participants will be monitored through hospital visits during their recovery period, including follow-ups at two and six weeks after surgery. Researchers will collect data on any device or procedure-related adverse events, spontaneous neural activity, signal quality, and device deficiencies. The total study period includes enrollment through the six-week postoperative follow-up to evaluate safety and device performance.
