Brief Summary:
Many types of cancer are primarily treated with surgery and patient survival is directly related to the extent to which the tumor is able to be removed. It is often difficult for surgeons to distinguish tumor tissue from normal tissue or to detect tumor cells that have spread from the original tumor site, resulting in incomplete removal of the tumor and reduced patient survival. In some sites, such as the brain, it is critical to avoid damage to normal tissue around the tumor to prevent adverse effects of surgery on function. Tozuleristide is a drug that is thought to attach to tumor tissue and then fluoresces (glows) when a special light from the Canvas is shined on it. It is hypothesized that tozuleristide, when imaged with the Canvas, will improve surgical outcomes by allowing surgeons to visualize the edges of the tumor or other ambiguous tissue in real-time as they operate. The purpose of this study is to evaluate how well tozuleristide imaged with Canvas work at helping to distinguish between tumor and normal tissue during surgery in pediatric primary central nervous system tumors.
Detailed Description:
Subjects who provide voluntary written informed consent, or have it provided by their legally acceptable representative, will be screened for eligibility. Subjects meeting all of the inclusion and none of the exclusion criteria will be eligible to participate.
Surgical excision will occur at least 1 hour and no more than 36 hours after tozuleristide administration. Surgery will be performed by a neurosurgeon and the Canvas will be operated by a designated Imaging Operator. Fluorescence of tumor and ambiguous tissue during surgery will be assessed and scored. Biopsy samples of these tumor and ambiguous tissues will be collected for pathology analysis.
All subjects will be monitored for safety during their participation in the study.
