📋 Regulatory Considerations

  • PBPK widely accepted by FDA/EMA for DDI and pediatric applications
  • QSP models require case-by-case regulatory discussion
  • AI/ML platforms gaining acceptance via DDT pathway
  • Model qualification vs. verification important distinction
  • ASME V&V 40 standard for computational model credibility

🔬 Selection Criteria

  • Primary application (PK, efficacy, safety)
  • Regulatory acceptance requirements
  • Integration with existing workflows
  • Budget and team expertise
  • Cloud vs on-premise deployment needs

📈 Industry Trends

  • AI/ML enhancing traditional mechanistic models
  • FDA Modernization Act driving digital twin adoption
  • Integration of in vitro NAMs data with PBPK
