The Misconception Around Preclinical Data
Pre-clinical data often carries a misconception regarding its role in health claim submissions. Let's clear up these misunderstandings.
Pre-clinical Data vs. Human Studies
Many believe that a significant amount of positive pre-clinical data can reduce the need for human studies. This is not necessarily true. Pre-clinical data is valuable, but it cannot replace human intervention studies.
Supportive Role of Pre-clinical Data
Pre-clinical data includes animal model data and in vitro studies. Its primary role is to support human data. It provides early insights but does not establish cause and effect.
EFSA's Stance on Preclinical Data
EFSA's guidelines emphasize that human intervention studies are crucial. They use pre-clinical data as supplementary evidence. If human data is inadequate, EFSA may not even review the pre-clinical data.
The Hierarchy of Evidence in EFSA's Decision-Making
Understanding EFSA's hierarchy of evidence is essential for successful health claim submissions. This section breaks down their approach.
Cause and Effect
EFSA prioritizes cause and effect in their decision-making. This means proving the direct impact of a product on health outcomes.
Human Intervention Studies
Human intervention studies sit at the top of EFSA's hierarchy. These studies provide the most robust evidence for cause and effect.
Supportive Evidence
Pre-clinical data serves as supportive evidence. While it can strengthen a submission, it cannot replace human data.
EFSA's Past Applications
Reviewing past applications shows EFSA's preference for human data. They often disregard pre-clinical data if the human data is insufficient.

Boosting the Impact of Pre-clinical Data in Your Submission
Understanding how to leverage pre-clinical data effectively can significantly strengthen your dossier, even though it cannot replace human data.
Organizing Your Dossier
The structure of your dossier is fixed, typically divided into six parts. Each section offers an opportunity to strategically present your data:
- Introduction
- Background Information
- Study Design
- Results
- Discussion
- Conclusion
Linking Mechanistic Work to Human Outcomes
Pre-clinical data often demonstrates the mode of action. It's crucial to link this mechanistic work to the outcomes measured in human studies.
For instance, if pre-clinical data shows a specific biological mechanism, ensure your human data aligns with this mechanism. This makes your case more compelling.
Addressing Reviewer Question Marks
Reviewers will naturally have questions about the relevance of your pre-clinical data. Addressing these concerns proactively is key:
- Relative dosing: Ensure the dose in animal studies is relevant to human studies.
- Duration of intervention: Align the duration in animal studies with human studies, considering life cycle differences.
Mapping Pre-clinical Data to Human Data
Mapping pre-clinical data to human data is essential for underpinning your submission. This involves correlating pre-clinical findings with human outcomes.
For example, if an animal study shows a certain effect at a specific dose, demonstrate how this translates to your human study results.
Strengthening Your Submission
While pre-clinical data cannot prove cause and effect, it can significantly bolster your submission. Use it to support and reinforce your human data.
By effectively linking mechanistic work to human outcomes and addressing reviewer concerns, you can maximize the impact of your pre-clinical data.
Pre-clinical Data's Influence on Successful Health Claims
Pre-clinical data has played a crucial role in some successful health claims, though it always works in conjunction with human data.

By understanding the importance of pre-clinical data and how to leverage it effectively, you can increase the likelihood of a positive health claim outcome.
The Exception Rather Than the Rule
While pre-clinical data can be influential, it often serves as the exception rather than the rule in successful health claim submissions.
Rare Success Cases
There are instances where pre-clinical data has played a critical role. However, these cases are rare.
For example, the sugar beet fiber case is one such rare instance. It succeeded with minimal human data, supported by robust pre-clinical findings.
EFSA's Cautious Approach
EFSA generally takes a cautious approach to pre-clinical data. They prioritize human studies and treat pre-clinical data as supplementary.
In most submissions, pre-clinical data alone is insufficient to sway EFSA's decision.
Balancing Expectations
It's essential to balance expectations when relying on pre-clinical data. Recognize its supportive role but don't expect it to replace human data.
Understanding this balance can help in preparing a more realistic and effective submission.
The Importance of Linking Pre-clinical and Human Data
One of the most effective ways to strengthen your submission is by linking pre-clinical data with human data.
Creating a Cohesive Narrative
To create a compelling submission, ensure that your pre-clinical and human data tell a cohesive story.
Align the biological mechanisms observed in pre-clinical studies with the outcomes measured in human trials.
Mechanistic Insights
Pre-clinical studies often provide valuable mechanistic insights. These insights can explain how a product works at a biological level.
Use these insights to support and rationalize the findings in your human studies.
Addressing Gaps
Identify and address any gaps between pre-clinical and human data. This can involve explaining differences in dosing, duration, or biological responses.
Proactively addressing these gaps can strengthen your overall submission.
Practical Examples
For instance, if your pre-clinical data shows a specific biological effect, ensure your human data measures the same effect. This alignment can make your case more robust.
Use practical examples to illustrate how pre-clinical findings translate to human outcomes.
Final Thoughts
Linking pre-clinical and human data is crucial for a strong submission. It helps create a cohesive narrative and addresses potential reviewer concerns.
By effectively integrating pre-clinical insights with human data, you can enhance the overall credibility and persuasiveness of your health claim submission.
