Abstract Current gaps in drug safety sciences can result from the inability 1 to identify hazard across multiple target organs, 2 to predict and risk assess with certainty against drug safety liabilities for the major target organs, 3 to optimally manage and mitigate against drug safety liabilities, and 4 to apply principles of governance on the generation, integration, and use of experimental data.

Figure 2. Figure 3. In silico tools can offer some physicochemical properties in model build Edginton, Concentration gradients in exposure maintenance may become important factors in chronic exposure or delayed toxicodynamic events Soldatow et al. No temporal events ie, acute responses are perturbations of the biological system, but chronic assessment of risk requires maintaining exposure. Most AOPs are descriptive and in vitro tests are typically short term 24—72 h tests. Models can be adapted to study effects of drug toxicities up to 2—4 weeks. No single in vitro model will recapitulate a complete AOP pathway.

Mitochondrial depletion independent of cell death Kamalian et al. Toxicology species and AOPs are not relevant to human. KE can relate biology between species and animals.

Examples of reverse translation can be applied to probe ADRs. A network-based approach to understanding drug toxicity and species may help explain mechanisms of toxicity and predict distinct toxicity phenotypes Sutherland et al. Limited application eg, Poor understanding between cellular events and target organ AO. Insufficient mechanistic knowledge. Safety testing typically focuses on a few endpoints and not mechanisms. A signal KE test that typically unifies a particular clinical outcome can support hazard identification for a particular ADR.

Studies to investigate hypersensitivity reactions can be studied and response determined in in vitro tests Azoury et al. Limited direct applicability to drug safety assessment. Species differences prevent building of AOPs for interspecies comparative assessment.

Limited amount of usable interspecies data and information. Patterns of co-regulated genes can Potentially be studied in lieu of specific genes where there are suspected orthologue differences. Coexpression when conserved have higher functional significance Bergmann et al. Need to develop AOPs and prioritize key investment areas to generate alternatives to safety testing.
