Situation
Regulatory agencies are responsible for protecting public health across food safety, drug safety, environmental exposures, and emerging threats. The volume and complexity of data—genomic, environmental, toxicological, exposure-based—have grown exponentially.
- To manage this scientific and operational burden, the FDA has increasingly turned to predictive analytics:
- Genomic clustering for outbreak detection
- Survival and growth kinetic modeling for pathogens
- Quantitative exposure models for drugs and chemicals
- PBPK modeling for overdose prediction
- Environmental modeling for pathogen spread
Cognizance’s scientific teams have supported FDA centers by developing actionable models that reduce uncertainty and enhance regulatory decisions.
Challenge
Regulatory scientists face major barriers:
1. Highly heterogeneous datasets – Genomic, environmental, toxicological, and clinical data are difficult to harmonize.
2. Lack of standardized predictive workflows – Different FDA centers use different modeling practices, slowing adoption.
3. Limited translational models – Traditional animal and in-vitro tests often lack predictive power for real-world behavior.
4. Data overload for outbreak and exposure investigations – Investigators can be overwhelmed by thousands of genome sequences, environmental samples, or exposure scenarios.
There was a need for validated predictive analytic tools that are standardized, interpretable, and directly useful for FDA regulatory staff.
Solution
Cognizance’s scientistic teams developed a suite of predictive tools and analytics frameworks, supported by peer-reviewed publications:
1. Genomic Analytics for Food Safety
- Whole genome sequencing (WGS) pipelines for outbreak attribution
- Comparative genomics to identify strain persistence, virulence, and transmission pathways
- Automated clustering models for foodborne pathogens
Impact areas: outbreak response, contamination traceback, environmental monitoring.
2. Predictive Microbial Risk Models
- Growth/survival kinetic models on produce, mushrooms, nuts, frozen vegetables
- Transfer models for E. coli from feedlots to nearby environments
- Ecological survival models for Campylobacter in dairy systems
Impact areas: FSMA risk assessments, inspection prioritization, prevention strategies.
3. Quantitative Exposure and Toxicity Models
- PBPK models for fentanyl exposure and opioid overdose
- Toxicokinetic models for environmental stressors (ozone, PFAS, noise, particulates)
- Predictive mutagenicity modeling for nitrosamine impurities
Impact areas: drug safety evaluations, chemical risk assessments, emergency pharmacology.
4. Machine Learning & Best Practices for Predictive Systems
- ML frameworks for interpreting microphysiological systems (MPS) outputs
- Modeling guidance to standardize predictive tools across regulators
Impact areas: regulatory harmonization, model validation, cross-center consistency.
Results
The predictive analytics programs enabled:
✔ Faster outbreak attribution – WGS-based models reduced time to identify contamination sources.
✔ More accurate food safety risk assessments – Survival/growth models powered quantitative risk assessments for high-risk commodities.
✔ Improved drug safety insights – PBPK models provided mechanistic understanding of opioid exposures and countermeasure effectiveness.
✔ Enhanced environmental monitoring – Predictive models identified airborne microbial transmission pathways near agriculture facilities.
✔ Greater regulatory confidence – Standardized modeling frameworks increased reproducibility and transparency—key for regulatory adoption.
These analytics tools are now key components of ongoing FDA scientific support.
