Drug development targeted at pediatric populations has been the subject of a great deal of careful thought and effort by clinical and nonclinical scientists and regulators over the past 25 years. In this podcast, Dr. Judith “Judy” Henck, who is a consulting toxicologist with over 30 years of experience in the pharmaceutical industry, will be interviewed. Dr. Henck's areas of scientific expertise include developmental, reproductive, and juvenile toxicology, as well as developmental neurotoxicology. Some of the unique features of pediatric drug development and in particular focusing on nonclinical safety assessment of pharmaceuticals intended to be used in pediatric populations will be discussed.
