GLEOLAN (aminolevulinic acid hydrochloride)

Oncology Approved 2017-06-06

Gleolan is an optical imaging agent used for patients with high-grade gliomas, specifically those suspected to be WHO Grades III or IV. It helps surgeons visualize malignant tissue during brain surgery by making the tumor cells stand out from healthy tissue. This tool is used as an adjunct to assist in the identification of cancerous areas while the patient is in the operating room.

How GLEOLAN Works

This drug works by causing a specific metabolite called PpIX to accumulate within tumor cells. When exposed to a specialized blue light source during surgery, this metabolite causes the malignant tissue to glow red while healthy tissue appears blue. This allows the surgical team to visually distinguish cancerous cells from surrounding brain tissue.
