Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

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.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
