Maeda, M.D., Ph.D., Professor Emeritus of Kumamoto University and Professor of Sojo University, Institute of Drug Delivery Science, is a worldrenownedexpert in macromolecular therapeutics. He was successful in creating theworld first polymeric drug, SMANCS (1979), which was approved for treatment of hepatoma in Japan in 1993. Along thisline he discovered the concept of EPR (enhanced permeability and retention)effectof macromolecular drugs, aubiquitous mechanism which is responsible for solidtumorselective targeting of polymeric drugs. More recently,he has developed a numbers of macromolecular/micellar drugs with very high tumorselectiveaccumulation. Thisconcept is also applicable to micellar and liposomal drugs, genecomplexednanoparticles,and even oncolyticvirus particles. He received his Masterís Degree from the University of California at Davis, where he was aFulbright Fellow, and his Ph.D. and M.D. from Tohoku University in Sendai, Japan. He has had more than 450papers published in international reputed journals. He received the Princess Takamatsu Award in Cancer Research,Dr. Tomizo Yoshida Award thehighest award from Japan Cancer Association in 2011, and other awards fromvarious societies in USA, Germany, UK and Japan. He is an awardee of the 2016 Thomson Reuter Web of Science Citation Laureates in Chemistry division, top 3 in the world.
