Kenjie Amemiya, PhD, DABT

Vice President Safety Assessment, Senior Consultant

Dr. Amemiya brings over 25 years in the pharmaceutical industry as a drug development toxicologist in therapeutic areas including oncology, neurology, anti-psychotics, anti-infectives, cardiovascular, respiratory and inflammation. His experience includes research phase and development project team leadership, extensive experience in GLP compliance, and a specialized focus on reproductive toxicology and its application to patient safety. He has had the opportunity to be part of four market applications – two in oncology, an anti-infective and an orphan drug.

Two of the more recent exciting experiences for Kenjie have been serving as a Clinical Drug Safety Scientist and as a member of the Roche Patient Drug Safety Committee, applying translational skills towards the development of healthy volunteer/patient safety management. He also recently led a SEND cross-functional Genentech team to the successful implementation of a validated submission management tool and business process. Kenjie believes that the most challenging and exciting opportunities in drug development center around ever-increasing expectations to understanding drivers of toxicity, and evermore, the translation of non-clinical safety findings to healthy volunteer and patient safety management strategies.

“Our focus should be on patient safety using all the tools we have in our safety arsenal – extensive application of target biology, in silico and screening tools and finally focused and decision-making animal studies. Having had the opportunity to live in the clinical safety arena after so many years in non-clinical has made me realize that more than ever, conversations between non-clinical and clinical safety scientists and sharing those learnings with health authorities will be the key to developing safer drugs.”
