Evidence Synthesis

Literature, existing test data, chemistry, and device context brought together into one coherent report.

Endpoint Conclusions

Clear assessment of which endpoints are addressed, waived, unresolved, or still require more evidence.

Chemistry Integration

Chemical characterization and TRA logic connected back into the biological safety argument.

Residual-Risk Framing

Conclusions written in a form that supports the technical file, FDA summary, and risk-management narrative.

When This Service Fits

Best for teams that already have evidence, but need a defensible scientific conclusion

The BER is where the biological evaluation becomes reviewer-facing. It needs to explain what evidence exists, how strong it is, what it means for each endpoint, how chemistry fits in, what residual risks remain, and whether the file truly supports biological safety for the finished device.

Testing and Literature Already Exist

You have data, reports, or chemistry outputs, but the package still needs a clear scientific synthesis and endpoint conclusion.

Current BER Reads Too Generically

The draft does not explain device context, endpoint logic, or waiver basis clearly enough for external review.

Legacy BER Needs Updating

You need to reframe older documentation around current ISO 10993 expectations, lifecycle thinking, and benefit-risk language.

Reviewer Asked for Clarification

The evidence may exist, but the conclusions, endpoint treatment, or chemistry framing are not convincing in the current file.

What the Work Includes

What a strong BER actually needs to do

A BER should not just repeat test results. It needs to evaluate the evidence and explain why the overall biological safety conclusion is defensible.

Finished-Device Framing

The report describes the real patient-contacting device, not an abstract material list disconnected from manufacturing and use.

Evidence Appraisal

Literature, prior test data, chemistry, and equivalence claims are examined for relevance, quality, and limitations.

Endpoint-by-Endpoint Conclusions

Each biological endpoint is addressed clearly, including what evidence supports it and where the reasoning is strongest or weakest.

Waiver and Existing-Data Logic

Endpoints not supported by new testing are backed with explicit scientific reasoning rather than generic statements.

Chemistry and Toxicology Integration

When chemical characterization or TRA exists, the report explains how that chemistry changes the biological safety conclusion.

Residual Risk and Benefit-Risk

The final narrative explains the remaining uncertainty and whether the evidence package supports acceptable biological safety.

Typical Use Cases

Situations where BER quality usually decides reviewer confidence

These are the cases where the report itself often becomes the main issue, not just the data in the appendix.

EU MDR technical-file submission

Where the notified body expects the biological safety story to be tied to the broader device documentation and Annex I context.

FDA 510(k) and AI response support

Where the reviewer needs endpoint conclusions and evidence framing that are much clearer than the current file provides.

Legacy BER remediation

Where old reports rely on outdated structure, weak literature framing, or poor linkage to current device configuration.

Files with scattered supporting data

Where the testing, chemistry, and literature may exist, but the report never brings them into one persuasive narrative.

Implants and prolonged-contact devices

Where endpoint interpretation, chemistry, and residual-risk reasoning usually need more depth than average.

Teams trying to defend waived endpoints

Where the file must show clearly why existing evidence is sufficient and where the real uncertainties still sit.

Workflow

How a BER scope is usually structured

The work starts with the evidence you already have and ends with a report that tells a clearer scientific story.

01

Review the Available Evidence

Device description, test reports, chemistry data, literature references, and existing evaluations are reviewed together.

02

Assess the Endpoints

The available evidence is mapped against the relevant endpoints, with attention to device representation and evidence strength.

03

Draft the Report

The BER is written to explain the evidence, the gaps, the waiver logic, and the overall biological safety conclusion clearly.

04

Finalize the Reviewer-Facing Version

The final output is refined for the specific submission or remediation context so it is easier for a reviewer to follow and defend internally.

FAQ

Questions teams usually ask before starting a BER

Can you work from an existing draft BER?

Yes. Many projects start with an existing draft that needs stronger endpoint logic, better chemistry integration, or clearer scientific writing.

Do you also review literature quality?

Yes. The literature itself is not enough; its relevance, limitations, and connection to the finished device need to be evaluated.

Can the BER include chemistry and TRA conclusions?

Yes. Where chemistry and toxicology are part of the biological safety argument, they should be integrated into the report rather than treated as detached appendices.

Can you update a BER for ISO 10993-1:2025 expectations?

Yes. That is a common use case, especially where lifecycle framing, benefit-risk language, and waiver quality are weak in the current file.
