First in Human (FIH) Clinical Investigation of Safety and Feasibility of a Novel Graphene Micro-electrocorticography Array for Brain Mapping in Neuro-oncology
The goal of this clinical investigation of a medical device is to test the safety of graphene based electrodes when used during surgery for resection of brain tumors. The main questions that it aims to answer are: * To understand the safety of the Graphene Cortical Interface when used during brain tumor surgery (primary objective); * To assess the quality of the brain signals recorded with the Graphene Cortical Interface, their ability to stimulate the brain, how stable their function is over the duration of an operation, and their suitability for use in the operating theatre (secondary objectives). Participants will undergo tumor surgery as usual with the study electrodes being tested alongside a standard monitoring system. If they are awake for part of their surgery they may be asked to complete specific tasks such as naming objects from a list modified for the study, to evaluate the capability to decode brain signals (exploratory objective). They will be monitored subsequently for any complications including undergoing an additional MRI scan 6 weeks after their surgery.
• Solitary supratentorial tumor radiologically consistent with glioma (intrinsic primary brain tumor) on standard diagnostic MRI;
• Planned for surgery under awake conditions or under general anesthesia with intra-operative electrocorticography (ECoG);
• English as first language for those subjects with tumors associated with language areas;
• Karnofsky performance score \> 70 and World Health Organization (WHO) performance status score ≤ 1;
• Willing and able to understand and provide informed consent for participating in the study.
