RE:RE:RE:RE:Photodynamic Therapy: Wide-spread treatment soon...To answer my own question, the company is Steba Biotech based in Belgium. A private company with their own proprietary compound - Tookad based on a variaiation of the cholorophyl molecule (quite innovative when you think about it). Like enrique says, proof of concept and it could one day come down to a battle of the PDT's. Big pharmas will want to have one but these developments point towards birighter days ahead for cancer suffererers.
