One Dossier. Thousands of Connected Language Decisions.
A CTD or eCTD is not simply a collection of regulatory documents. It is an interconnected body of scientific, quality, clinical, administrative, and product information that has to remain consistent as reviewers move between summaries and the underlying evidence.
Product names appear in multiple modules. Manufacturing terminology flows from detailed Quality/CMC sections into higher-level summaries. Study identifiers, endpoints, adverse event terminology, specifications, units, tables, and conclusions may recur throughout the dossier. Approved regulatory language may also need to carry forward into authority responses, updated sections, variations, and future submissions.
When connected materials are translated independently, terminology and meaning can drift between files that are supposed to describe the same product, study, process, or conclusion.
Five Modules. One Connected Regulatory Dossier.
Module 1 contains region-specific administrative and product information, while Modules 2 through 5 form the harmonized CTD structure for summaries, quality, nonclinical, and clinical content.
Module 2 has a particularly important relationship with Modules 3, 4, and 5. Its summaries and overviews condense the underlying Quality, nonclinical, and clinical evidence. Sesen helps keep terminology, values, findings, and conclusions aligned between the summary layer and the supporting dossier content.
Regional and Administrative Content
Module 1 is different from the rest of the CTD because its content and structure are determined by regional requirements rather than the harmonized Modules 2–5 framework.
Depending on the market, submission pathway, and stage of review, multilingual Module 1 work may involve content such as:
- Application and administrative forms
- Cover letters and regulatory correspondence
- Product and prescribing information
- Labeling-related documentation
- Regional declarations and certificates
- Risk-management or supporting administrative content
- Market-specific supporting documents
- Responses and other authority-facing communications
Translation requirements can vary significantly between jurisdictions. Rather than applying a single approach to every market, Sesen works from the agreed regulatory scope, target authority, submission pathway, document type, and intended use.
At the same time, Module 1 cannot be treated in isolation. Product names, indications, dosage information, terminology, and approved regulatory language may need to remain consistent with corresponding content elsewhere in the dossier.
Summaries That Must Reflect the Underlying Evidence
Module 2 sits at the center of the CTD’s scientific narrative. Its Quality, nonclinical, and clinical summaries and overviews distill information that is developed in much greater detail in Modules 3, 4, and 5. As a result, Module 2 translation requires more than polished language. It requires disciplined alignment with the underlying evidence.
Quality Overall Summary
Maintain terminology and technical meaning between the Quality Overall Summary and the detailed Quality/CMC information presented in Module 3.
Nonclinical Overview & Summaries
Keep pharmacology, pharmacokinetic, toxicology, study terminology, and conclusions aligned with supporting Module 4 documentation.
Clinical Overview & Summaries
Maintain consistency with clinical study reports, endpoints, safety terminology, efficacy findings, statistical language, and other evidence presented in Module 5.
Cross-Module Terminology Control
Identify recurring product, study, manufacturing, clinical, and regulatory terminology before inconsistent language spreads through high-level summaries.
Numerical & Reference Verification
Support consistency in values, units, study identifiers, section references, tables, and other information that connects summaries to supporting documents.
One Summary Layer, Three Evidence Sources
When Module 2 condenses evidence from Modules 3–5, the terminology cannot be managed independently.
Quality and CMC Translation
Module 3 contains technically dense Quality and Chemistry, Manufacturing, and Controls information where precise terminology and disciplined reuse are especially important.
- Drug substance information
- Drug product information
- Composition and formulation
- Manufacturing processes
- Process controls
- Specifications
- Analytical procedures
- Analytical method validation
- Batch-related information
- Stability studies and data
- Container closure information
- Supporting Quality documentation
A single manufacturing term, material designation, analytical method, specification, or process description may recur throughout Module 3 and appear again in the Module 2 Quality Overall Summary. For recurring submissions and lifecycle changes, terminology may also need to remain consistent with previous regulatory versions.
Sesen combines specialized pharmaceutical and scientific linguists with terminology management, translation memory, reference alignment, numerical checks, and structured review to help protect technical consistency across Quality content.
Explore CMC Translation ServicesNonclinical Translation
Module 4 brings together the nonclinical evidence supporting the product’s development and regulatory assessment.
- Pharmacology
- Pharmacokinetics
- Toxicology
- Nonclinical study reports
- Study findings and conclusions
- Tables, figures, and supporting scientific content
- Nonclinical literature references
Scientific terminology, study identifiers, test articles, doses, units, findings, and conclusions must remain accurate within the individual documents while also aligning with the corresponding nonclinical summaries and overview in Module 2.
Our workflow helps preserve these connections through subject-matter linguist assignment, terminology preparation, reference materials, translation memory, bilingual review, and targeted quality checks.
Clinical Study Reports and Clinical Evidence
Module 5 contains the clinical evidence supporting regulatory evaluation of a product’s safety and efficacy.
- Clinical study reports
- Tabular listings of clinical studies
- Study results and supporting evidence
- Statistical analyses and clinical data
- Tables and figures
- Endpoint terminology
- Safety and adverse event language
- Literature references and supporting clinical evidence
- Related clinical documentation used within the submission program
Clinical content is rarely confined to a single document. Study titles, protocol identifiers, endpoints, treatment terminology, safety language, numerical data, and conclusions may recur throughout the dossier.
Sesen helps maintain alignment between detailed clinical evidence in Module 5 and the Clinical Summary and Clinical Overview in Module 2 while also connecting approved terminology to the broader clinical documentation program.
Regulatory Consistency Has to Extend Across the Entire Dossier
The five modules serve different purposes, but regulatory reviewers evaluate the relationships between them. Sesen helps control the elements most likely to create multilingual inconsistencies across connected CTD and eCTD content.
Product & Substance Terminology
Maintain approved names, compounds, dosage forms, routes of administration, formulations, and recurring product language across modules and versions.
Manufacturing & Quality Terminology
Keep process descriptions, specifications, analytical terminology, materials, methods, and Quality concepts aligned between Module 3 and Module 2.
Clinical & Nonclinical Terminology
Maintain study terminology, endpoints, safety language, findings, and conclusions between supporting reports and corresponding summaries.
Numbers & Units
Check dosages, concentrations, specifications, measurements, statistical values, dates, and other quantitative content where translation errors can be especially consequential.
Study & Document Identifiers
Preserve protocol numbers, study numbers, document identifiers, product codes, and other controlled references.
Cross-References
Review references to dossier sections, tables, figures, appendices, and supporting documents so multilingual content remains navigable and internally consistent.
Approved Language
Reuse previously approved or client-authorized terminology where appropriate instead of introducing unnecessary variation.
Reviewer Decisions
Capture accepted regulatory, medical, scientific, CMC, clinical, or affiliate feedback so approved language can inform related documents and future updates.
Version Relationships
Keep new translations connected to previous content so updated submissions do not lose the regulatory language history already established.
The Dossier Keeps Changing After the Initial Submission
The first submission is only one point in the regulatory lifecycle. Health authority review, revised evidence, product changes, and post-approval activity can continue to affect dossier content long after the initial filing.
Initial Submission
Establish controlled terminology, translation memory, reference materials, module relationships, and review processes at the beginning of the multilingual program.
Authority Review
Keep translated dossier content, prior decisions, references, and source history available as regulatory review progresses.
Questions & Requests for Information
Support multilingual health authority correspondence, clarification requests, deficiency questions, and related regulatory communications.
Response & Updated Content
Apply approved terminology and prior translation decisions to revised dossier content while maintaining alignment with earlier submissions.
Variations, Supplements & Amendments
Manage changes to manufacturing, clinical, labeling, safety, administrative, and other regulatory content without unnecessarily retranslating unchanged material.
Renewals & Lifecycle Maintenance

Every Regulatory Change Can Affect More Than One Module
Sesen helps manage language continuity across two dimensions at once: across the structure of the dossier and across the life of the regulatory submission.
A Manufacturing Change Begins in Module 3
The same change may also require updates to the Module 2 Quality Overall Summary, regional Module 1 documentation, product information, cross-references, or future authority responses.
New Clinical Evidence Enters Through Module 5
It may affect the Clinical Summary, Clinical Overview, labeling-related conclusions, market-specific documentation, or later regulatory communications.
Translation Built for Structured eCTD Workflows
The CTD defines the organization of regulatory content. The electronic Common Technical Document, or eCTD, provides the structured electronic environment through which that content can be submitted and maintained over time.
That distinction matters for translation. Multilingual documents have to preserve more than their sentences. Depending on the project and publishing workflow, they may also contain structured headings, tables, figures, bookmarks, hyperlinks, internal references, file relationships, and version dependencies that need to remain usable after translation.
Supporting an Evolving eCTD Environment
The global eCTD environment continues to evolve as health authorities transition from established eCTD v3.2.2 workflows toward eCTD v4.0 on different regional timelines.
Sesen’s role is to help keep multilingual regulatory content accurate, structured, traceable, and ready for the client’s applicable document and publishing workflow as submission standards evolve.
Maintain Regulatory Language Across Every New Sequence
A new submission sequence should not require teams to reconstruct years of multilingual decisions. Controlled language assets help carry established regulatory history forward.
Translation Memory
Reuse previously translated and reviewed content where source text has not materially changed.
Approved Terminology
Maintain product, clinical, CMC, nonclinical, safety, and regulatory terminology across documents and versions.
Reference Materials

Reviewer Decisions
Preserve accepted reviewer feedback so resolved terminology and language choices are not repeatedly reopened.
Change Analysis
Differentiate new or revised content from unchanged text to focus translation and review effort where it is needed.
Version Control
Maintain visibility into source and target versions so teams can identify which multilingual files correspond to the current regulatory content.
Controlled Reuse
Carry forward approved language while ensuring changes are reviewed in their new regulatory context rather than reused blindly.
Support Multilingual Submissions Across Global Regulatory Markets
Global regulatory programs frequently reuse a common scientific foundation while applying different regional requirements, submission pathways, languages, product information, and timelines.
Sesen supports multilingual regulatory programs across major and emerging life sciences markets, including North America, Europe, Asia-Pacific, Latin America, the Middle East, and other international regions.

Read CTD & eCTD Translation ConsiderationsCTD & eCTD Translation FAQ
Answers to common questions about CTD modules, multilingual dossier consistency, eCTD workflows, lifecycle updates, and Sesen’s regulatory translation support.
The Common Technical Document, or CTD, defines the standardized organization of regulatory information used in pharmaceutical submissions. The electronic Common Technical Document, or eCTD, provides the structured electronic submission environment used to transmit and maintain that regulatory content. In practical terms, CTD defines the content architecture, while eCTD adds the electronic structure and lifecycle used for submission and subsequent regulatory activity.
Module 1 contains regional administrative and product information and is specific to the applicable regulatory region. Modules 2–5 follow the harmonized CTD structure: Module 2 contains summaries and overviews, Module 3 covers Quality/CMC, Module 4 contains nonclinical study information, and Module 5 contains clinical study reports and supporting clinical evidence.
Yes. Sesen supports multilingual content across Modules 1–5. The actual translation scope depends on the target market, authority, submission pathway, source documentation, regulatory stage, language requirements, and client needs.
No. Module 1 is region-specific. Administrative forms, product information, labeling-related documents, correspondence, and other Module 1 content vary according to the applicable health authority and regional requirements.
Module 2 contains high-level Quality, nonclinical, and clinical summaries and overviews that draw from the more detailed evidence in Modules 3, 4, and 5. Terminology, values, findings, and conclusions therefore need to remain consistent between the summary layer and the underlying supporting documentation.
Sesen can use client-approved glossaries, terminology databases, translation memory, previous submissions, product information, regulatory references, reviewer decisions, style guides, and automated quality checks to help maintain consistency across connected dossier content. Qualified human linguists and reviewers validate the final language in context.
Yes. Sesen provides specialized translation for Quality and CMC documentation, including drug substance and drug product information, manufacturing processes, specifications, analytical methods, validation, stability content, and related regulatory documentation.
Yes. Sesen supports clinical study reports and related clinical evidence used within Module 5, as well as broader clinical trial documentation through its dedicated Clinical Trial Translation Services.
Yes. Sesen can support multilingual health authority correspondence, requests for information, clarification packages, deficiency responses, revised submission content, and related regulatory communications. When prior translations are available, terminology, translation memory, reference materials, and approved reviewer decisions can help maintain continuity with the original filing.
Yes. Sesen supports recurring regulatory changes after the initial submission. Depending on the program, this can include updated Quality content, clinical evidence, labeling-related material, safety information, regional documentation, responses, variations, supplements, amendments, and other lifecycle content.
Yes, where appropriate. Translation memory and previous approved translations can help identify unchanged or recurring content and improve consistency. Reuse should still be evaluated against the current source, context, terminology, and regulatory requirements rather than applied automatically.
Sesen can establish controlled terminology before or during the translation program using source documentation, glossaries, existing translations, product terminology, reviewer input, and translation memory. Cross-document QA can then help identify deviations between Module 2 summaries and the corresponding detailed Quality, nonclinical, or clinical content.
Sesen supports translation and multilingual document preparation for regulatory programs operating in today’s evolving eCTD environment, including programs moving toward eCTD v4.0. The exact technical scope depends on the client’s regulatory publishing environment, target authority, regional requirements, and required deliverables.
Sesen’s core role on this page is multilingual regulatory translation and document preparation. Technical formatting and publishing-related support can be incorporated according to the agreed project scope and client workflow. Clients requiring specialized eCTD formatting or publishing support should discuss their technical requirements with the Sesen team during project planning.
Yes. Sesen supports multilingual regulatory programs across major global markets in more than 150 languages. Programs can be organized around shared source content while accounting for target-market language requirements, regional Module 1 content, local reviewer involvement, and differing regulatory timelines.
Depending on scope, quality controls can include specialist linguist selection, independent bilingual review, terminology management, translation memory, reference alignment, numerical and unit checks, completeness checks, cross-document consistency review, formatting verification, AI-assisted QA, final human quality assurance, and controlled client review.
