Human Abuse Liability Role in NDAs

Life Sciences, Clinical Trials, Pharmaceutical Regulation,
  • Tuesday, April 15, 2014

Abuse and addiction are serious global health problems. All drugs with rewarding properties have the potential to be abused. Therefore the FDA requires most CNS acting drugs to be assessed for their abuse potential. The most common clinical method for drugs to be evaluated for their abuse potential is with a Human Abuse Liability (HAL) study.

The presentation will discuss when a HAL study will likely be required and how a HAL study is conducted.
