Health Authority Query Response Writing for Sponsors

Pubrica drafts responses to health authority questions and deficiency letters for sponsors. A response letter is written to a fixed deadline, read by a reviewer who has already raised a concern, and becomes part of the regulatory record. Common problems include answering a question that was not asked, conceding more than the question required and making commitments that have not been costed. Our regulatory medical writers keep each answer within the scope of the question, support it with evidence and check it against what you can deliver.

  • Each question answered on its own terms, in the order asked, so the reviewer can close each one without searching
  • Evidence assembled for each answer, including cross-references, data, literature and, where a new analysis is needed, the analysis itself
  • Commitments stated precisely, because a sentence written under time pressure can become a post-approval obligation that must be funded
  • Scope limited to the question, because answering more than was asked can raise questions the reviewer had not asked
  • Written to your deadline, with the turnaround agreed against your response deadline

Deliverables

Four Core Elements of Every Health Authority Query Response

Each response addresses one set of questions to one deadline, and what was asked determines what the response covers.

Question analysis before drafting For every question, we establish what is being asked, what would satisfy the reviewer and whether the evidence exists before drafting starts.

From the question analysisA question about the statistical handling of dropouts is not a question about efficacy. Answering about efficacy instead invites a follow-up on the dropout handling, which had not been raised.

Evidence assembled and cross-referenced We provide the data, module and page references, literature and any new analysis the question requires, so the reviewer can verify the answer without asking again.

From the responseAs discussed in the submission, the safety profile is acceptable.See Module 2.7.4, Table 2.7.4.3 and CSR section 12.2. The rate in subjects over 65 was 8.1% against 6.9% overall; the difference is not significant and the analysis is appended. Verifiable in one step.

Deliverable commitments Every commitment in a response becomes a post-approval obligation, so we identify the cost and the owner before the wording is included.

From the commitment reviewWe will conduct a post-marketing study to further characterise this finding.Flagged before submission: unbounded in design, population, timing and cost. Rewritten to a specific, costed and time-bound commitment the company had agreed internally.

Scope held to the question Responses that volunteer additional analysis, data or reassurance usually lead to further questions.

From the scope checkThree paragraphs of unrequested context removed from a draft response. The reviewer asked about one endpoint in one subgroup; the draft discussed four.

All samples are illustrative and anonymised. Hover over a sample to replay it.

Compliance and Standards

Four Governing Standards and Guidelines for Query Responses

Agency conventions differ, and the format of a response is particularly important in this type of regulatory writing.

REGconventions

Agency response conventions (FDA, EMA, MHRA, CDSCO, TGA)

Structure, numbering, cross-referencing and the expected level of detail differ by agency and procedure, so a response formatted for one agency may not meet the expectations of another.

CTDmodules

CTD and eCTD structure (where the supporting evidence is located)

Responses cross-reference the submission. A reference that does not lead to the correct module and section costs the reviewer time and reduces confidence in the response.

ICHE6(R3)

Good Clinical Practice (E6(R3), not E6(R2))

Annex 1 took effect in the EU in July 2025; Annex 2, covering pragmatic and decentralised designs, follows in January 2027.

ISO9001:2015

Quality management (cert. H3CR9TCU20251212INDQM10N)

Governs how each document is drafted, reviewed, version-controlled and released.

Responsible Use of AI

Responsible Use of AI in Regulatory Writing

Regulatory reviewers trace each decision back to evidence and to a responsible individual. Our specialists therefore treat source traceability as more important than speed, and every statement in a document must be supported by a traceable source.

How We Use AI ToolsWe use AI tools to locate source material across a document set, to check the consistency of terms, figures and cross-references between documents in a submission, and to draft highly templated sections, which a writer then verifies line by line against the source.
Where We Do Not Use AIWe do not use AI to draft text that enters a submission, to interpret clinical or benefit-risk data, to write safety narratives, to appraise literature for a clinical evaluation, or to produce any statement that an assessor would expect to trace to a named, qualified individual.
Your AI Use DeclarationYour declaration states the tool used, the stage at which it was used and the human oversight applied. Journals, funders, regulators and the ICMJE January 2026 update all expect this disclosure, and an undeclared tool discovered later is treated as an integrity matter.

Why We Do Not Publish AI Accuracy Figures

Accuracy figures for AI tools are usually reported by the companies that sell them.

For this reason, Pubrica does not quote an accuracy figure of its own, as it would carry the same conflict of interest. We tell you which tool was used on your project, at which stage, and what a specialist changed afterwards.

Methodology

How Our Health Authority Query Response Writing Process Works

Analysing the questions is the main part of the work, and drafting begins once everyone agrees what is being asked.

Step one

Question analysis

We read each question to establish what is being asked and what would satisfy it, and record the evidence position as available, requiring analysis, or not available.

Step two

Evidence assembly

We gather data, cross-references and literature for each question, and scope and commission any new analysis early.

Step three

Drafting and commitment review

Each answer is written in the agency’s conventions, and every commitment is reviewed for deliverability before it is included.

Step four

Review cycles within the deadline

We consolidate your regulatory, clinical and statistical comments in each cycle and work to the response deadline rather than a standard turnaround.

FAQs

Health Authority Query Response FAQs

If your question is not answered here, ask an expert. No quote is required.

We work to your deadline. Response periods are fixed and short, so the turnaround is agreed against your deadline rather than offered as a standard figure.

The main constraint is usually whether a question needs new analysis rather than the drafting itself. We establish this in the first two days, which is why it is important to send the letter immediately.

This is established in the question analysis on the first or second day, so the analysis can be commissioned in parallel rather than identified late.

We can carry out the analysis, including analysis of your locked dataset, pooled analyses and literature-based support, or work alongside the team that does.

A commitment in a response becomes a post-approval obligation. A sentence written under time pressure can create a study that must be designed, funded and delivered over several years.

We flag every commitment before it is included, with its likely cost and owner. Some commitments are worth making, but each should be a deliberate decision.

No. Volunteering additional analysis or reassurance usually leads to further questions and extends the review.

Answer what was asked completely and verifiably. Where you believe the reviewer has misunderstood something, address it directly rather than expanding the scope.

No. The response is prepared for your signature and submitted by you or your regulatory function, in your name.

We prepare, cross-check and format the response; you approve and submit it. It becomes part of your regulatory record and must be issued in your name.
