Gleolan for Visualization of Newly Diagnosed or Recurrent Ovarian Cancer (OVA-302)

Gleolan is a prodrug that is metabolized intracellularly to form the fluorescent molecule Protoporphyrin IX (PpIX). The oral provision of Gleolan leads to a highly selective accumulation of PpIX in tumor cells. Following excitation with blue light (BL) (wavelength \[λ\] = 375 - 450 nm), the PpIX, which has accumulated selectively in tumor tissue, emits a red-violet light.
