Meet Sesen at DIA 2025 in Washington, D.C.
Join us June 15–19 at Booth #2013 to explore global clinical and regulatory language solutions.

Why Protocol Translations Matter

Clinical trial protocols are the foundational documents that define the study design, objectives, methodology, statistical considerations, and operational details. Accurate translation of these protocols is critical for ensuring that every site, regardless of location or language, executes the trial according to the same standardized procedures.

Protocol translations are a critical component of our broader Clinical Trial Translation Services that ensure regulatory compliance and site alignment across global studies.

Without precise and contextually accurate translations, multilingual trial sites risk misinterpreting inclusion criteria, treatment regimens, or safety reporting requirements. These discrepancies can lead to protocol deviations, patient safety issues, and compromised data integrity.

Global regulatory authorities such as the FDA, EMA, PMDA, and those adhering to ICH-GCP guidelines often require protocol translations for submissions, ethics committee reviews, and investigator training. Poor-quality translations can delay approvals or trigger compliance audits.

Sesen’s protocol translation services help sponsors and CROs eliminate these risks by delivering accurate, regulator-ready translations that ensure site compliance, uphold Good Clinical Practice, and maintain consistency across global operations.

Expert Linguists and Medical Review

Sesen’s protocol translation services are delivered by a highly specialized team of professional native linguists with deep experience in clinical research and regulatory documentation. Each translator is carefully selected based on subject matter expertise, language proficiency, and knowledge of Good Clinical Practice.

We assign linguists with proven therapeutic area expertise, including oncology, rare diseases, central nervous system disorders, cardiovascular studies, and more. This ensures that all clinical terms, study objectives, and safety instructions are translated with precision and contextual accuracy.

All protocol translations undergo medical review by certified MDs or PhDs fluent in the target languages. These reviewers validate scientific terminology, review critical sections for clinical accuracy, and ensure alignment with country-specific regulatory expectations.

To maintain consistency and accelerate turnaround, we apply internal quality control workflows, including:

  • Centralized translation memory systems to preserve terminology across projects
  • Client-specific glossaries for brand and regulatory alignment
  • Multi-step linguistic QA and final verification checks before delivery

Our team-driven approach ensures that every protocol translation meets the highest standards of linguistic accuracy, clinical relevance, and regulatory readiness.

Human-Centric Translation Enhanced by Technology

Sesen combines advanced translation technology with subject matter expertise to deliver fast, accurate, and cost-effective protocol translations. Our human-centered approach is supported by intelligent tools that enhance consistency, accelerate timelines, and ensure compliance across global studies.

We leverage translation memory (TM) and termbase integration to maintain consistency across documents, reduce redundancy, and improve turnaround times. Each client’s approved terminology is stored and reused across protocol versions, amendments, and related documentation to ensure accuracy and regulatory alignment.

For high-volume or repetitive content, we offer hybrid translation workflows that combine secure, domain-specific machine translation with expert human post-editing. This approach increases efficiency while preserving the high quality required for clinical submissions and trial conduct documentation. Hybrid workflows are used selectively and only when appropriate for the document type and regulatory context.

Sesen also supports API and platform integrations with clinical trial management systems (CTMS), electronic trial master files (eTMF), and document review platforms. These integrations streamline file exchange, automate status updates, and facilitate real-time collaboration between sponsors, CROs, and translation teams.

By blending technology with human expertise, Sesen delivers protocol translations that meet the demands of modern clinical operations while upholding the highest standards of quality and compliance.
