Regulatory medical writing
for clinical trials

Our experienced medical writers support every stage of clinical development, creating high-quality clinical and regulatory documents that align with your data, meet global requirements and accelerate submission readiness.

One consistent story, across every document

Our senior medical writers bring clinical, regulatory and scientific content together across four capability areas, so the evidence stays aligned from protocol through to submission.

Clinical study documentation

Clinical trial documents developed in close collaboration with biostatistics and data management, keeping the protocol, analysis and final reporting scientifically aligned from start to finish.

  • Clinical trial protocols Sponsor-ready protocols and amendments with biostatistics and CDM consistency from day one.
  • Clinical trial reports (CTR) ICH E3 reports co-authored with biostatisticians for tight TFL–narrative alignment.
  • Investigator brochures (IB) IB authoring and lifecycle maintenance, preclinical chapters in step with the science.

Regulatory submission documents

Regulatory medical writing for CTD content, integrated summaries and submission packages, prepared to meet global regulatory requirements and support a clear, consistent evidence story.

  • CTD Module 2 documents Clinical overviews and summaries for INDs, MAAs and NDAs.
  • ISS / ISE integrated summaries Integrated Summaries of Safety and Efficacy with full traceability across pooled trials.
  • Document QC & peer review Expert peer review and quality control against dedicated checklists, whether or not we authored the document.

  • IND / MAA / NDA
  • CDISC-compliant datasets
  • FDA / EMA / PMDA requirements

Safety & reporting

Safety writing and reporting for ongoing clinical programmes, including periodic and case-level documents that support regulatory compliance and keep safety information accurate and current.

  • Participant safety narratives Templated and bespoke narratives for SAEs and adverse events of interest, pooled for ISS/ISE.
  • Annual reports / DSURs / PBRERs Development Safety Update and Periodic Benefit-Risk Evaluation Reports across active programmes.

Scientific communications & publications

Scientific and participant-facing content tailored to the audience, from lay summaries and congress materials to peer-reviewed manuscripts and journal publications.

  • Plain-language / lay summaries EU CTR-compliant lay summaries and participant-friendly synopses reviewed for accessibility.
  • Participant information & ICFs Information leaflets and informed-consent forms pitched at the target reading level.
  • Scientific publications Peer-review-ready manuscripts with ICMJE alignment and journal-specific formatting.
  • Congress & non-clinical writing Congress materials, preclinical reports and IND/CTA tox sections bridging into the clinical narrative.

From clinical data
to a clear evidence story

Clinical trial reports written with the same rigour as the data behind them, bringing the analysis, clinical context and trial conclusions together in one clear narrative.

A Metronomia medical writer at work

Evidence in every document

Protocols, CTRs and submission content are where the trial evidence is ultimately understood. We bring the same rigour to the documents as we do to the data behind them.

Narrative aligned with data

Our medical writers work in close collaboration with biostatisticians and programmers, keeping the written interpretation consistent with the SAP, TFLs and final analysis.

Written for the audience

Our MSc and PhD-level writers shape every document around the people who need to use it, whether participants, the public, scientists or regulators. Each piece is then quality-checked against the relevant guidance and style requirements.

Connected from start to finish

From synopsis and protocol through to CTRs, briefing books, ISS/ISE narratives and lay summaries, we keep the evidence consistent across the full document chain.

One writing team across development

From trial documents and regulatory submissions to safety reporting and scientific communications, our writers support the full clinical development journey.

Clinical trial writing

Protocols, clinical trial reports, participant narratives and sponsor publications, authored end to end across phases I–IV.

Protocol development

Protocol and synopsis authoring with biostatistical and operational input from the first draft, aligned to ICH E6, ICH E8 and ICH M11.

Clinical trial reports

ICH E3 reports drafted against the same shells the programmers code, with biostatistical review running in parallel.

Non-clinical writing

IND and CTA preclinical sections, toxicology reports and the non-clinical chapters that bridge into the clinical narrative.

One evidence story, from protocol to submission

Protocols, IBs, CTRs and integrated summaries need to stay scientifically aligned. One team keeps the endpoints, analyses and conclusions consistent across every document, from first synopsis through to final submission.

  1. Protocol

    Where you commit to the analysis — the endpoint defined here is the question everything downstream answers.

  2. IB

    Investigator brochure and lifecycle maintenance, preclinical chapters in step with the non-clinical writing.

  3. CTR

    The trial's primary analysis, drafted against the same shells the programmers code — ICH E3 by default.

  4. ISS / ISE

    The pooled summary across trials — full traceability back to every individual CTR that feeds it.

Questions we’re often asked

Do you offer QC, peer review and formatting services only?
Yes. Irrespective of whether we authored the document, we can support it through expert peer review, quality control against dedicated QC checklists, and professional formatting. These services can be commissioned on their own, without any authoring scope attached.
How do you ensure clinical trial report consistency with the SAP and TFLs?
The report is authored against the SAP and the TFL shells the programmers code from, with biostatistical review running in parallel rather than as a hand-off at the end. Our medical writers work in close collaboration with the biostatisticians and programmers who own those outputs, so the narrative and the numbers stay in step as both develop.
Do you write protocols from scratch or only edit?
Both — though we strongly prefer to be involved from the synopsis stage. Protocols co-authored with biostatistics from day one have meaningfully fewer amendments and cleaner deviations than protocols inherited late. Authoring follows ICH E6, ICH E8 and the ICH M11 protocol template where the sponsor works to it.
Can you write ISS / ISE narratives?
Yes — both the integrated safety summary and integrated efficacy summary, with full traceability across pooled trials and CDISC-compliant supporting datasets. Routine ISS/ISE work is part of our submission portfolio.
Do you support EU CTR lay summaries?
Yes. EU CTR has changed the lay-summary expectation significantly. We write to the 2024 best-practice guidance with participant-friendly language reviewed for accessibility.
Do you handle eCTD submissions?
We prepare and quality-control the documents that go into an eCTD submission — CTD Module 2 content, integrated summaries and supporting reports — formatted and checked so they drop straight into your dossier. We do not run the technical publishing process itself: the eCTD compilation, validation and gateway upload stay with your publishing vendor or in-house team, and we work alongside them.
