It still is my opinion that they didn't want a competitive product to outshine theirs.
Hi Apophis....Porfirmer sodium is no longer patent protected & I can't imagine Photofrin is a big money maker for Roswell at this point. Why else would Roswell agree to participate in an in vitro study of TLD 1433 other than to basically find a better option to the limited first generation PS (Photofrin). The very positive in vitro results of TLD 1433 (& likely its future derivatives imo) showed great potential to put their illustrious PDT program back on the map. Either the drug is still being studied/considered for a future trial or there is some other non-scientific reason, & I don't think it's related to Roswell not being interested. All JMO.
