Drug abuse liability assessment: Early evaluation for regulatory success

Drug abuse liability assessment is a critical component of nonclinical drug development for compounds (or metabolites) that have CNS activity, evaluating the potential for misuse, dependence, and reinforcing properties. Beyond regulatory expectations, these findings directly influence clinical trial design/requirements, labeling, scheduling, and patient safety, making early and integrated assessment essential.

Assessing abuse potential presents several challenges across therapeutic areas. Compounds with CNS activity may produce unexpected reinforcing or dependence-related effects with risk influenced by pharmacology, exposure, formulation, and route of administration.

An abuse liability assessment is typically conducted late Phase II/Phase III; however, discussions/planning should start early in the development program.

Why choose Labcorp?

  • Integrated development approach, linking abuse liability to pharmacology, PK, and safety assessment
  • Extensive behavioral expertise, with deep experience in interpreting complex functional endpoints
  • Regulatory-ready execution, supporting global submission requirements and scheduling evaluations
  • Mechanism-driven study design, tailored to compound-specific risk and development goals
  • Translational insight, connecting preclinical findings to clinical strategy and patient safety considerations

Our solution: Integrated abuse liability assessment

Labcorp delivers mechanism-driven abuse liability studies designed to provide a comprehensive understanding of the misuse and/or abuse potential and regulatory risk. This integrated approach connects pharmacology, exposure, and behavior, enabling a complete assessment of abuse potential within the context of drug development.

Pharmacological activity and mechanism of action

Pharmacokinetics and systemic/CNS exposure

Active metabolites and duration of effect

Behavioral and functional outcomes

Core study capabilities

  • Drug discrimination to assess if a test agent shares a similar interoceptive cue as that of a known drug of abuse
  • Intravenous self-administration to assess the potential rewarding and reinforcing effects of a novel test agent
  • Physical dependence on withdrawal of a test agent (induction of a withdrawal (discontinuation)) syndrome
  • Pharmacological tolerance
  • Conditioned place preference for the assessment of the potential rewarding effects of a test agent
  • Head twitch response for the assessment of potential 5-HT2A activation
  • Cannabinoid tetrad for the assessment of potential CB1 agonist effects

These studies provide a holistic understanding of abuse risk, behavioral effects, and potential impact on patients.
