CTD to eCTD conversion dossier preparation by MedWisdom Lifesciences

What Is CTD to eCTD Conversion — And Why Does It Matter?

The Common Technical Document (CTD) is a standardized format for pharmaceutical regulatory submissions. While paper-based CTDs were once the norm, global regulatory authorities — including the US FDA, EMA, and CDSCO — now mandate or strongly prefer submissions in electronic CTD (eCTD) format, which is structured, searchable, and lifecycle-managed.

CTD to eCTD conversion involves restructuring existing paper or digital dossiers into the XML-based eCTD format, complete with proper backbone structure, technical validation, and sequence management — ensuring full compliance with regional and international guidelines.

  • Mandatory for FDA (US) and EMA (EU) electronic submissions
  • Required for CDSCO submissions in India (NDA/ANDA/IND)
  • Enables lifecycle management — amendments, supplements, and renewals
  • Reduces reviewer processing time and accelerates approval timelines
  • Facilitates multi-regional submissions from a single master dossier

Our CTD to eCTD Conversion Process

A structured, quality-driven workflow ensures your converted eCTD dossier is accurate, validated, and submission-ready on the first attempt.

1

Gap Analysis & Document Review

We audit your existing CTD dossier to identify structural gaps, missing data, and compliance issues before conversion begins.

2

Document Preparation & Compilation

All source documents — PDFs, Word files, study reports — are formatted, hyperlinked, and bookmarked per ICH eCTD specifications.

3

eCTD Backbone Structuring

We build the XML backbone and folder hierarchy compliant with ICH M8 guidelines for the target regulatory authority.

4

Technical Validation

The eCTD package is validated using approved validation tools (e.g., Lorenz, Certus) to detect and resolve errors before submission.

5

Submission & Lifecycle Support

We submit the validated eCTD to the regulatory authority and provide ongoing lifecycle management for amendments and renewals.

Region-Specific eCTD Publishing

eCTD packages customized for specific authorities: FDA (USA), EMA (EU), CDSCO (India), Health Canada, TGA (Australia), GCC countries, and more — each with region-specific Module 1 administrative sections.

eCTD Technical Validation & QC

Independent technical validation of your existing or newly prepared eCTD using industry-standard validation tools. We identify and resolve structural, hyperlink, and XML errors prior to regulatory submission.

eCTD Lifecycle Management

Ongoing management of your eCTD lifecycle including sequence updates for amendments, supplements, Type I/II variations, post-approval changes, and renewal submissions — ensuring continuity and compliance throughout your product's regulatory history.

Dossier Gap Analysis & Remediation

Pre-conversion gap assessment against current ICH CTD/eCTD guidelines to identify missing documents, outdated data, or non-compliant formatting — with a clear remediation plan before submission.

Why Convert from CTD to eCTD?

Understanding the key differences helps pharmaceutical companies make informed decisions about upgrading their regulatory submissions.

Criteria Paper / Legacy CTD Electronic CTD (eCTD)
Submission Format Physical binders or unstructured PDFs XML backbone with structured, hyperlinked PDFs
FDA/EMA Compliance ✗ No longer accepted by FDA/EMA ✓ Mandatory for US & EU submissions
Lifecycle Management ✗ Manual, error-prone updates ✓ Automated sequence management
Reviewer Processing Slow; requires manual document navigation Fast; fully searchable and hyperlinked
Multi-Regional Submissions ✗ Requires separate full dossiers per region ✓ Single master dossier, region-specific Module 1
Approval Speed Longer processing due to format limitations Faster approvals with compliant, validated submissions
Post-Approval Changes Full resubmission of affected sections Incremental sequence updates only

Frequently Asked Questions — CTD to eCTD Conversion

Quick answers to the most common questions about our CTD to eCTD conversion services in India.

What is the difference between CTD and eCTD?
CTD (Common Technical Document) is the internationally agreed-upon format for regulatory dossiers, which can exist as paper binders or unstructured PDFs. eCTD (Electronic CTD) is the electronic implementation of the CTD format — structured using an XML backbone, with hyperlinked documents organized into a standardized folder hierarchy. eCTD enables lifecycle management (amendments, supplements) as sequential updates, unlike paper CTD which requires full resubmission.
Is eCTD submission mandatory in India (CDSCO)?
Yes. The Central Drugs Standard Control Organisation (CDSCO) has mandated eCTD format for New Drug Applications (NDAs), Abbreviated New Drug Applications (ANDAs), and Investigational New Drug (IND) applications. Pharmaceutical companies in India must comply with CDSCO's eCTD guidelines for all relevant submissions. MedWisdom's team is fully versed in CDSCO eCTD requirements and can guide your transition efficiently.
How long does the CTD to eCTD conversion process take?
Timelines depend on the size and complexity of the dossier, the quality and format of source documents, and the target regulatory authority. A straightforward conversion for a single product may take 2–4 weeks, while complex multi-module or multi-regional dossiers can take 6–12 weeks. After an initial gap analysis, we provide a detailed project plan with clear milestones and delivery dates.
Which regulatory authorities do you support for eCTD conversion?
We support eCTD preparation and conversion for all major global regulatory authorities including: US FDA (CDER, CBER), EMA and EU Member States, CDSCO (India), Health Canada, TGA (Australia), GCC countries (Saudi Arabia, UAE, Kuwait), PMDA (Japan), and other global markets. Each authority has specific Module 1 requirements and submission portal processes that our team manages on your behalf.
What source documents do you need to begin the conversion?
We work with a wide range of source materials including: scanned paper CTD binders (PDF), digitally compiled CTD documents (Word, PDF), study reports, pharmacokinetic and clinical data, quality (CMC) documentation, and any existing regulatory correspondence. Our initial gap analysis will specify any additional documents needed before conversion begins.
Do you also manage eCTD lifecycle submissions (amendments, supplements)?
Absolutely. eCTD lifecycle management is one of our core capabilities. Once your initial eCTD is submitted, we manage all subsequent sequences including Type I and Type II variations, post-approval changes (PACs), annual reports, supplemental applications, and renewal submissions — maintaining the integrity and continuity of your regulatory submission history.
How much do CTD to eCTD conversion services cost?
Pricing depends on factors including the number of modules being converted, the volume and complexity of source documents, the target regulatory authority, and whether lifecycle management support is required. We offer transparent, project-based pricing with no hidden fees. Contact us for a personalized quote tailored to your specific dossier and regulatory requirements.
