Question 1

What is regulatory gap analysis software?

Accepted Answer

Regulatory gap analysis software compares a submission's current state against the complete requirements for a specific filing type (IND, NDA, BLA, 510(k), etc.) and an authority (FDA, EMA, Health Canada) and surfaces what's missing. Good gap analysis is continuous (not a one-time check) and risk-scored (not just a binary present/absent list). It handles required content, conditional content that depends on the product profile, and recommended but non-mandatory content. The output is a prioritized remediation list with owners and deadlines, not just a gap report.

Question 2

How is gap analysis different from validation?

Accepted Answer

Validation checks whether the content you have is structurally correct: valid XML, proper lifecycle operations, working hyperlinks, metadata compliance. Gap analysis checks whether the content you need is actually there: does Module 3.2.P.8.3 exist, does it have the required stability data, does the method validation report cover all specifications. A sequence can pass validation (everything present is structurally correct) and fail gap analysis (required content is missing). Both checks are needed; most teams run validation and miss gap analysis.

Question 3

Can gap analysis run against EMA and Health Canada requirements?

Accepted Answer

Yes. Gap analysis rulesets are maintained per authority. An IND gap analysis runs against FDA IND requirements; a CTA gap analysis against Health Canada requirements; an MAA gap analysis against EMA requirements. Regional differences (Module 1 content, language requirements, specific technical documents) are handled by switching the ruleset. Teams filing in multiple regions run gap analysis against each region's requirements from the same source content, which surfaces where reuse is possible and where region-specific content is missing.

Question 4

What does 'readiness score' actually measure?

Accepted Answer

Readiness score is an objective percentage derived from gap closure weighted by risk. A submission at 85% readiness has 15% of its required content either missing or flagged for quality concerns, weighted by how much each gap would affect acceptance. The score is not a prediction of FDA review outcome — that depends on content quality, not content presence — but it is a reliable predictor of whether the submission will be refused-to-file or pass the technical acceptance check. Teams typically target 95%+ readiness at T-14.

Question 5

How does gap analysis handle changing requirements?

Accepted Answer

Requirements change: FDA publishes new guidance, ICH finalizes a workstream, a specific product review raises new expectations. Assyro's gap analysis rulesets update as guidance evolves, and existing programs can be re-evaluated against current requirements at any time. When a gap rule changes, Assyro flags which of your active programs are affected by the rule change and whether the current submission state still meets the updated requirement.

Question 6

Can gap analysis tell us what FDA will ask for in a deficiency letter?

Accepted Answer

Not reliably. Deficiency letters are content-quality questions about the data FDA sees, not content-presence questions about what's missing. Gap analysis covers the latter. It's a strong predictor of refuse-to-file risk and of information requests tied to obvious missing items, but it cannot anticipate substantive scientific questions about clinical efficacy, CMC adequacy, or statistical analysis. Teams that mistake gap analysis for 'will FDA approve' are misreading the tool. Use it to avoid preventable deficiencies, not to predict all review outcomes.

Question 7

How does this connect to writing and publishing?

Accepted Answer

Gap analysis findings flow into the writing and publishing workflow: a gap becomes a task assigned to a specific author, the author drafts the missing content, the content passes through review, and closure of the gap updates the readiness score automatically. Without this integration, gap analysis becomes a report that someone emails around; with it, gaps become actionable work that closes through the team's normal writing workflow. This is the difference between gap analysis as a checklist and gap analysis as an operating layer.

Question 8

Do we need gap analysis if we already have a submission checklist?

Accepted Answer

A Word or Excel submission checklist serves the same conceptual purpose, but has three practical weaknesses: it's maintained by someone who has to keep it current; it reflects whatever version of requirements existed when it was built; and it's disconnected from the submission state, so updating the checklist requires someone to compare against the live work. Gap analysis software automates all three: the rulesets stay current, the comparison against submission state runs continuously, and findings route to owners automatically. Teams running 3+ active submissions typically outgrow a checklist by the second program.
