FG001 in Subjects with Meningiomas or Presumed Low-Grade Gliomas Scheduled for Neurosurgery

Summary

In neurosurgery both the diffusely infiltrated gliomas of the brain as well as the border towards healthy tissue in the meninges is a challenge. For the high-grade contrast enhanced gliomas fluorescent drugs like Gliolan have been used in several years and proved its clinical value. For non-contrast enhanced gliomas, like low-grade glioma, no such drug exist. The transition zone towards healthy non-tumor cell infiltrated brain in such low-grade gliomas is extremely difficult but for these patients their prognosis depends on the amount of non-healthy tissue left behind. Also, in benign tumors as meningioma the complete resection including infiltrated meninges is of importance for the cure of the disease. None of the existing fluorescent drug is useful or approved for these tumors.. Hence a medicinal product that will fulfil the criteria for a safe and reliable fluorescent drug to guide the surgery to the boundaries of the infiltration with tumor cells is highly warranted.
