Developers of drugs with central nervous system (CNS) activity rightly focus on physical safety and efficacy first, particularly in the case of products intended for rare disorders or diagnoses often unresponsive to existing therapeutic options. These products may have little if any apparent CNS mediated effects but crossing the blood-brain barrier is sufficient to trigger the FDA requirement for an abuse potential assessment. This webinar is the second part of a 2-part series.
Part 1 on June 28, discusses the following:
- FDA Guidance on Assessment of Abuse Potential of Drugs: What drug development timelines need to avoid delays and unexpected costs
- Assessment needed to characterize a drug’s potential as part of the safety evaluation of the substance
- Non-clinical safety assessments and human data
- Assessments to provide early indication of the potential need for risk management programs
This second webinar in a two-part series will provide a complementary overview of the requirements for conduct of Human Abuse Potential assessment and clinical abuse potential data integration into the regulatory framework of an 8-Factor Analysis. The session will include a discussion of recent experience and regulatory interactions with the FDA, along with information on submitting an abuse potential assessment and the needed components of a full development plan, details on design, analysis and interpretation of human abuse liability studies. Featured speakers will outline the principals and issues involved in the design, analysis and interpretation of clinical abuse potential studies and discuss the potential for the Take Drug Again subjective response to serve as a primary endpoint in HAP studies.
The webinar will have the following learning objectives:
- Outlining the principles and issues involved in the design, analysis and interpretation of clinical abuse potential studies
- Consider timing and strategy of the assessment of human abuse potential in order to satisfy regulatory requirements/expectations
- Understand the integration of clinical data in the 8-Factor Analysis/Modular Abuse Potential submission to FDA
Topics will include:
- Determining a drug’s abuse potential
- When Should an Abuse Potential Assessment be submitted to FDA?
- What should be included in an Abuse Potential Submission?
- Human laboratory studies
- Human abuse potential study in recreational drug users
- Related pharmacology studies
- Clinical trial data relative to Abuse Potential Assessments
- Labeling and drug scheduling
- Discuss the potential of the Take Drug Again endpoint as a primary endpoint in Human Abuse Potential
- FDA 8-Factor Analysis/Modular Abuse Potential Submission to FDA in NDA
This webinar is the second of a 2-part series. Click here for information about Part 1.

Jack Henningfield, PhD, Vice President, Research, Health Policy, and Abuse Liability at PinneyAssociates
Jack E. Henningfield, Ph.D., Vice President, Research, Health Policy and Abuse Liability, PinneyAssociates, and Professor, Adjunct, Behavioral Biology, Department of Psychiatry and Behavioral Sciences, The Johns Hopkins University School of Medicine.
Dr. Henningfield was trained in abuse liability assessment and related sciences in the Psychopharmacology Program at the University of Minnesota and the Behavioral Biology Program of The Johns Hopkins University in the 1970s. In 1980, he joined the National Institute on Drug Abuse (NIDA), which contributes to Controlled Substances Act drug scheduling, where he served as Chief of the Clinical Pharmacology Branch, and the Abuse Potential Assessment Section, and contributed to NIDA’s drug scheduling recommendations. In 1996 he left NIDA and joined PinneyAssociates to provide guidance on the clinical and nonclinical assessment of abuse potential and the development of abuse potential submissions including 8-factor assessments to guide drug scheduling recommendations to FDA and regulatory agencies outside of the US.
Dr. Henningfield has published more than 400 articles and books and contributed to abuse potential assessment monographs from NIDA in the 1980s, FDA’s first draft guidance in 1990, and expert reviews and special conferences on abuse potential involving FDA in the 2000s leading to FDA’s guidances for assessing the abuse potential of drugs and abuse deterrence of opioids.
