In Vitro NAM Data Standards
Date Submitted: 25 Mar 2024
Problem Statement
In Vitro Noval Alternative Methods (NAMs) are human cell-based assays and systems used in biomedical research which represent human physiology, predict clinical outcomes and and reduce, replace or refine the requirements for animal testing in drug discovery. In vitro NAMs include standard two-dimensional (2D) cell cultures, co-cultures, 3D assays, bioprinted tissues, organoids and microphysiological systems (MPS) or organs-on-a-chip. There are many companies and laboratories developing and validating these platforms, but the industry-at-large lacks standardization in method ontology, metadata, performance qualification, validation standards, and data management. Thus, drug discovery researchers lack guidance and confidence in adopting alternative methods to replace or complement animal studies.
Idea Proposal and Value Proposition
We propose to develop harmonized standards for describing animal alternative methods (assay metadata), their characterization (e.g., performance metrics), and develop best practices for management and analysis of data. This would help promote understanding and adoption of in vitro NAMs, leading to better drugs and safer products. Furthermore, such standards would help facilitate the integration of structured data sets for use in AI/ML applications.
Stakeholders benefiting from these standards would include:
- Program leaders wishing to incorporate human-relevant tests to replace or complement animal studies, as they would find it easier to find and evaluate these methods.
- Regulatory agency reviewers, who will better understand data from these methods when submitted in regulatory applications.
- CROs would benefit from an industry standard, as it would simplify data reporting to clients.
- Academic and industry assay developers, as this would give them clear guidance on expectations of assay users and regulators.
- Pharmaceutical companies would benefit from an industry standard, as it would reduce reformatting data.
To quantify the impact of this project, a survey of pharmaceutical researchers for their willingness to use or actual use of in vitro NAMs before and after the project deliverable can be developed. Longer term quantification can be measured by participating CROs as increased sales of NAMs services, or increased numbers of regulatory applications containing in vitro NAMs.
Critical Success Factors
Success factors include:
- Participation by pharmaceutical researchers interested in using in vitro NAMs in their programs.
- Participation by CROs who develop and/or run in vitro NAMs assays and interact with pharmaceutical researchers and understand their pain points.
- Participation by assay scientists (at CROs or pharma) with experience in diverse platforms as well as assay metrics.
- Participation by research data management and data standards experts who can provide input on systems and tools.
- Program leaders or participants who can lead the development of a peer-reviewed manuscript.
- Access to clinical data for reference pharmacology to translate in vitro application data to clinical indications.
- Participation by regulatory agency representatives to ensure model standards align with regulatory requirements and complement the IND-enabling portfolio.
Other Relevant Information
This project would benefit by input from a broad array of stakeholders including government groups. There are public databases such as PubChem, ChEMBL and the NIEHS’s ICE database of in vitro NAMs data that would benefit by alignment with this effort. Currently these tools are very chemistry-focused.
