AI and Human Expertise

Responsible AI for Regulated Trial Content

Speed matters in clinical trials, but regulated content carries no margin for error. Our approach keeps a qualified human expert in the loop at every stage.

Machine translation post-editing (MTPE) is available for lower-risk, high-volume material, and it is always refined by a specialist linguist. High-risk and patient-facing content, including informed consent forms, protocols, labeling, and safety reports, is translated by subject-matter expert linguists and reviewed under our ISO 17100 process. You choose the workflow, and we make sure the safeguards match the risk.

  • Human-in-the-loop
  • MTPE where appropriate
  • ISO 17100 review

IRB & Informed Consent

Under FDA 21 CFR Part 50 and ICH E6(R3), participants must receive consent documents in a language they fully understand. Our ICF translations are completed by subject-matter expert linguists, reviewed by a second independent linguist, and certified for IRB submission.

Our Process

A Validated 6-Step Translation Workflow

Every clinical trial translation follows a rigorous, documented process designed to meet regulatory inspection standards and ensure accuracy across all languages.

  1. Project Intake and Scoping

    Your dedicated project manager reviews document types, regulatory requirements, target languages, and timeline. A custom glossary and style guide are established or retrieved from your Translation Memory.

  2. Linguist Assignment

    Documents are assigned to subject-matter expert translators with verified credentials in your therapeutic area, such as oncology, rare disease, CNS, cardiovascular, or immunology.

  3. Translation and Terminology Management

    Translation proceeds using your approved glossary and Translation Memory. Every term is consistent with your previous submissions and aligned to regulatory terminology standards.

  4. Independent Review and QA

    A second independent linguist reviews the translation for accuracy, consistency, and regulatory compliance. Our QA team runs automated terminology checks and format validation.

  5. Back-Translation (if required)

    For ICFs and patient-facing materials, a third independent translator performs back-translation into English. Discrepancies are reconciled and documented for IRB submission.

  6. Delivery and Certification

    Final documents are delivered in your required format with a Certificate of Translation, audit trail, and version history, prepared for IRB, FDA, EMA, or PMDA submission.
