What Are Multilingual ePRO System Translators?
Multilingual ePRO (electronic Patient-Reported Outcome) system translators are specialized solutions that combine technology and linguistic expertise to accurately translate and culturally adapt patient-facing clinical trial materials. Unlike general translators, they are designed for the life sciences industry, ensuring that ePRO questionnaires, diaries, and instructions are clear, precise, and conceptually equivalent across multiple languages. These systems are essential for maintaining data integrity, ensuring patient safety, and meeting strict regulatory requirements (e.g., FDA, EMA). Solutions like X-doc.ai provide the security, accuracy, and workflow automation needed to manage ePRO localization for global clinical trials efficiently.

Google Cloud Translation API
Google Cloud Translation offers a highly scalable and robust API for machine translation. Its key differentiator for ePRO is AutoML Translation, which allows organizations to train custom MT models using their own domain-specific data (e.g., existing ePRO questionnaires, medical glossaries, clinical trial documents). This significantly improves the accuracy and relevance of translations for specialized medical terminology, forming a powerful foundation for a larger ePRO translation workflow.
