[ 03 · BUILDING THE EVIDENCE ]
The evidence map before your next experiment
“What do I actually need to have proved, and am I about to spend money on the wrong study?”
Most early programmes generate evidence in the order the science suggests, which is rarely the order a submission needs. Mapping the required evidence against what you hold turns a sequence of experiments into a plan, and usually reveals one study that should happen sooner and one that should not happen at all.
WHAT THIS IS NOT
Orientation for translating research toward a regulated product — not a determination of device status, regulatory pathway, submission type or clinical adequacy, and not a substitute for qualified regulatory advice. SPEQ is independent: linked institutions, incubators and agencies are third parties, and nothing here implies affiliation, endorsement or partnership with any of them.
ARE YOU HERE?
- You are designing the next study and the justification is momentum rather than a gap
- Nobody has written down what the eventual submission has to demonstrate
- You can describe your results but not which requirement each one satisfies
WHAT TO DECIDE NOW
- What the eventual evidence package must contain, at the level of "characterisation, safety, performance" rather than protocol detail
- Which existing results already satisfy part of it, and which will need repeating under different conditions to count
- Which study is on the critical path, which is usually not the one the team is most interested in
START KEEPING THESE RECORDS NOW
- The mapping itself — requirement against result against gap — because it is the artefact that makes a diligence conversation short
- Any study run before formal standards applied, with its conditions recorded honestly, so a later decision about whether it can be relied on is possible at all
- Reference standards, control material and their characterisation, which age out quietly
PUT IT TO WORK
SPEQ templates and tools for the work above. They structure it; they do not decide it for you.
- TEMPLATE · PLANGLP Study Plan →The plan a nonclinical safety study is run against, when a study on your map has to count toward a submission.
- TEMPLATE · RECORDTest Item Characterisation Record →Records what was actually dosed — the gap that makes an otherwise good early study need repeating.
- TEMPLATE · PROTOCOLStability Study Protocol →Stability is usually on the critical path and rarely the study the team is most interested in.
THE PROBLEM THIS ANSWERS
Development work generates records whose evidential value depends on properties captured at the time — contemporaneity, material provenance, instrument state — and none of them can be added afterwards.
What it costs: The loss is silent. Nothing fails, no alarm sounds, and the result simply stops being reproducible evidence at the moment somebody needs it to be.
An AI-enabled product depends on dataset provenance, model lineage and a frozen evaluation, and each of those is routinely reconstructed from memory rather than recorded when it was true.
What it costs: A performance claim that cannot be reproduced cannot be defended, and retraining without recorded lineage makes the earlier evidence unattributable to anything shippable.
WHERE THIS GOES WRONG
- Running the pivotal study before the analytical method that measures its endpoint is validated. The result then measures the method as much as the product.
- Assuming a study can be retro-fitted into compliance. Conditions that were not controlled cannot be documented into having been.
- Building the evidence map from the technology rather than from the claim, which produces a thorough package answering a question nobody asked.
WHAT THIS DOES NOT ANSWER
- Which specific studies a regulator will require, which depends on the pathway and is a question for scientific advice rather than for a guide
- Whether existing non-GLP work can support a submission — sometimes yes, sometimes as supporting rather than pivotal evidence, and it is fact-specific
