Representative Toxicologist Biographies

Drew Badger, Director of Global Regulatory Affairs at Amgen and President of ACT

Hanan Ghantous

Drew Badger, PhD, DABT is a Director of Global Regulatory Affairs at Amgen and President of ACT. In this capacity, he provides strategic leadership of global regulatory teams for biologic and small molecule programs spanning multiple therapeutic areas (neurology, oncology, inflammation, rheumatology) and various stages of development. This includes global regulatory submissions, ethnic bridging strategies, pediatric strategies, and device and companion diagnostic strategies, among others.¬†Prior to Amgen, Drew served as Senior Director of Toxicology and Regulatory Affairs at Amira Pharmaceuticals. Prior to this, he was the Director of Discovery Toxicology and Scientific Operations at Allergan following his entry role as Toxicology Study Director and Project Representative. Prior to this, Drew was a scientist at Procter & Gamble where he participated as Toxicology Project Representative for global chemical registrations in the consumer products division. Collectively, Drew has been employed with large, mid-size and small companies, worked in EPA and FDA-regulated arenas, supported development of small molecules and biologics, and served in various toxicology and regulatory leadership roles.

So how did this career path manifest? From the time of entering Humboldt State University as an art major and music minor, Drew never had a master plan for developing his career. By serendipity, in college he took elective courses in chemistry and toxicology that were so enriching and interesting, he opted to change his major to biochemistry and applied to graduate programs in toxicology. With his major advisor at The University of Arizona being President of SOT at this time, Drew was exposed to influential individuals who were active in the scientific community and he admired the pleasure and influence they derived from serving in those roles.¬† Following a 3-year stint at Procter & Gamble, Drew took his second job in industry at Allergan and recognized that he didn’t know much about discovery toxicology, his key job function at the time. As such, he proactively founded and presided over the drug discovery toxicology specialty section of SOT in order to establish contacts, develop expertise, and to provide a venue for like-minded scientists. Concurrently, he rotated through the presidential chain of Southern California SOT. Both of these leadership roles facilitated the opportunity to serve as Councilor and ultimately in the Presidential chain of ACT, and the development of many friendships across industry. It also allowed a toxicologist like Drew to transition into leadership roles in regulatory affairs at both Amira and Amgen without having a traditional background of more junior roles in regulatory affairs.

David Compton, Toxicologist in Preclinical Safety, Sanofi

David Compton

David Compton was born and raised in Missouri where he received his BA degree in chemistry from Washington University in St. Louis. Subsequently he received his PhD from the Department of Pharmacology and Toxicology at UTMB (University of Texas Medical Branch) in Galveston, where his dissertation research was on the neuropharmacology of antipsychotic medications, which was funded in part by an Individual Predoctoral Grant from the Scottish Rite Schizophrenia Foundation. At graduation he received both the Academic Excellence Award and the Jason E. Perlman Research Award. He conducted postdoctoral research on the neuropharmacology of drugs of abuse at MCV (Medical College of Virginia) in Richmond, the professional campus of VCU (Virginia Commonwealth University). During his two years on an Institutional Training Grant of the Department of Pharmacology and Toxicology, Dr. Compton was awarded a Pharmaceutical Manufacturers Association Foundation Award funding postdoctoral research into “Receptor and Nonspecific Mechanisms of Cannabinoid-Induced Alterations of Neurotransmission.” Subsequently he received a NIDA Individual Postdoctoral Grant to conduct research on the neurochemical/neurobehavioral effects of chemical analogs of Δ9-tetrahydrocannabinol (the psychoactive constituent of marihuana). 

During his academic career as assistant and associate professor at MCV-VCU in the Department of Pharmacology and Toxicology, Dr. Compton taught professional students (medical, pharmacy, etc.), was the advisor and/or committee member who mentored graduate (Masters and PhD) students, and continued research on drugs of abuse funded by NIDA grants (as individual primary investigator, as co-investigator, and as part of a multifaculty Center Grant). As a faculty member he published extensively in peer reviewed journals, co-authored books on abuse liability, and co-authored chapters in medical pharmacology texts. One of his most prized accomplishments was not his research on cannabinoids, stimulants, and anabolic steroids, but rather his Students’ Choice Award for Faculty of the Year in 1994. 

Though still currently an affiliate associate professor at VCU, after leaving his primary academic appointment, Dr. Compton gained valuable GLP (Good Laboratory Practices) experience in preclinical/ nonclinical toxicology as a Study Director on both US Environmental Protection Agency (US EPA)- and US Food and Drug Administration (US FDA)-mandated regulatory studies in general toxicology, reproductive toxicology, and safety pharmacology while working for Huntingdon Life Sciences, a CRO (Contract Research Organization) at the Princeton Research Center in New Jersey. Subsequently, he was an associate principal scientist at the Schering-Plough Research Institute focussing on drug development as the drug safety evaluation representative to project teams, prior to his positions as principal and lead (as of 2013) research investigator—toxicology and project team expert within preclinical safety at Sanofi US in New Jersey. Since 2007 he has served within Sanofi as one of a three-member expert group advising company project teams on development issues related to abuse potential. In 2010 he was the Sanofi US representative to PhRMA team generating the industry response to the US FDA draft guidance on Assessment of Abuse Potential of Drugs. 

Dr. Compton has more than 25 years of combined academic, contract laboratory, and pharmaceutical experience in the fields of neuroscience/neuropharmacology, abuse liability/assessment, education, study directing, toxicology, and preclinical drug development. In 1999 he was certified as a diplomate of the American Board of Toxicology (DABT). He has been a member of The NYAS since 1984.

He has been a full member of ACT (American College of Toxicology) since 1997 and has served on numerous elected positions. As of 2013, he is serving his final year (of a three year elected term) as a council member of ACT. He has been a full member of SOT (Society of Toxicology) since 2011, and is currently a full member of both CPDD (College on Problems of Drug Dependence) and the Society for Neuroscience, having first joined each as an associate/student member in the 1980’s. As a member of these organizations he has presented numerous scientific posters, given multiple symposia presentations, as well as organized and served as co-chair of symposia on drug abuse/liability. 

Dr. Compton was a founding member of the non-profit New Jersey Brain Bee Association in 2002 and served as the moderator of this annual spelling-bee style competition for high school students (qualifying the winner to compete in the International Brain Bee competition co-sponsored by the Society for Neuroscience). Other professional activities include serving as both instructor and member of the planning committee for the New Jersey Association for Biomedical Research-sponsored IACUC Training Workshops from 2006 to 2010, serving within Sanofi as the primary voting member for Drug Safety Evaluation of the US-based IACUC (Institutional Animal Care and Use Committee), and organizing/teaching in educational outreach programs to grade school- through college-aged students.
