It helps identify potential risks before a compound reaches human clinical trials, thereby improving safety and minimizing costly failures in later development stages.

According to FDA requirements, IND applications must include detailed preclinical safety data. These data come from pharmacological and toxicological studies, particularly in animal models, to show that a drug is reasonably safe for initial human use. The studies must demonstrate that the benefits outweigh the potential risks. As per FDA guidance, this safety evidence is critical to justify moving a drug candidate into clinical testing, ensuring compliance and minimizing harm to human participants.

Innovative approaches are reshaping early toxicity evaluations. In vitro methods, such as MTT, MTS, and ATP assays, are now widely used to assess cell viability and metabolic activity. For example, neutral red uptake evaluates membrane integrity, while ELISA-based cytokine assays detect inflammatory responses. These techniques offer reliable, ethical alternatives to animal testing by providing controlled, repeatable results on cellular toxicity. They form a foundation for efficient, early-stage toxicology screening in drug development.

Computational methods, or in silico toxicology, are also becoming important. These models predict the toxic potential of chemical substances using biological and chemical structure data. A notable example is the ToxCast Program by the U.S. Environmental Protection Agency (EPA), which screened 1,065 chemicals and achieved an accuracy of 79–82% for developmental toxicity prediction. Although sensitivity was below 67%, specificity exceeded 84%, showing strong potential in replacing some animal testing methods.

The eTOX project, a European initiative, has also advanced in silico tools. It utilized curated toxicology reports to develop predictive models for drug development, improving data reliability. Meanwhile, organ-on-a-chip (OoC) technologies have emerged as cutting-edge tools. These microfluidic systems mimic human organ functions more accurately than animal models. For instance, liver-on-a-chip devices have replicated species-specific drug toxicities and shown alignment with human clinical outcomes. This innovation supports more human-relevant toxicity testing.

Regulatory bodies are recognizing OoC potential. For example, the FDA accepted a liver-on-a-chip platform into its ISTAND program to assess drug-induced liver injury (DILI) risk. A study published in 2022 estimated that using these devices in DILI testing could generate over $3 billion annually for the pharmaceutical industry. Besides financial impact, these tools support ethical commitments by reducing animal use and offering more predictive data, thereby strengthening the overall drug development process.
