Official title

A Phase 2 Study of Aminolevulinic Acid (ALA) to Enhance Visualization and Resection of Tumors of the Brain

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The prodrug, 5-Aminolevulinic acid (ALA), has been shown to lead to intracellular accumulation of fluorescent porphyrins in high grade malignant gliomas in the brain. On imaging, this accumulation of fluorescent porphyrins helps delineate tumor borders, resulting in the surgeon being better able to visualize and thus able to make a complete, or near-complete resection of the tumor.
