Testing abuse deterrent properties of opioid formulations is a relatively new discipline. Guidelines for evaluation of abuse deterrent properties of branded was issued by the FDA in 2015. A guideline for evaluating abuse deterrent properties of generic products was issued in November 2017. Different stages of testing including in vitro tests (Category 1) and clinical human abuse liability studies (Category 2 &3) were identified as critical parts of the evaluation. Due to the very different nature of the Category 1 studies relative to the clinical studies, it was decided to initiate a focus group with people involved in Category 1 testing in order to have a forum where the study protocols, testing and interpretation of these data could be discussed. The group and meetings includes people from FDA, Academia and Industry including specialist consultants in Category 1 testing. This group is now part of the CCALC umbrella organization and is currently headed by Karsten Lindhardt and Sebastian Schwier. The meetings are organized by a steering committee.
First meeting was focused around the FDA guidance "Abuse Deterrent Opioids, Evaluation and Labeling -
Guidance for Industry "
The second meeting was focused around the FDA Guidance "General Principles for Evaluating the Abuse Deterrence of Generic Solid Oral Opioid Drug Products Guidance for Industry, November 2017"
