Dr. Cvitkovic, Chief Scientific Officer for Oncoethix, led the clinical development of single agent and combination regimens for cisplatin, vindesine, bleomycin, navelbine, and, more recently, irinotecan, oxaliplatin, docetaxel, and trabectedin, first as an academic investigator and then through a specialized oncology clinical research organization. Prior to founding Oncoethix and assuming responsibilities as Chief Operating Officer, Dr. Noel had co-founded another oncology drug development company which in-licensed oxaliplatin as its first portfolio product and subsequently identified, evaluated, and in-licensed novel agents for several clients. Additionally, Dr. Noel has developed expedited registration strategies for many cancer drugs and registration files for a few of these. Dr. Herait managed clinical development of irinotecan, from Phase 1 through Phase 3, while at Rhone Poulenc Rorer and subsequently, as a consultant, managed clinical studies for several novel cancer drugs.
Since its founding, Oncoethix has in-licensed three promising cancer drug candidates, each a first-in-class agent to a novel target or with a novel mode of action. Currently, two portfolio compounds are in clinical development.
