Ensuring Accuracy, Compliance, and Patient Safety

Global clinical research hinges on the integrity of both the data collected and the communication pathways established among sponsors, contract research organizations (CROs), investigators, and patients. High-quality translations are integral to this process, as a single misinterpreted phrase can undermine patient safety, skew trial results, or even invalidate an entire study in the eyes of regulatory authorities. Maintaining the accuracy of clinical documentation, such as protocols, informed consent forms (ICFs), case report forms (CRFs), and labeling, directly impacts patient well-being, data reliability, and timely market approvals.

At Sesen, we recognize the stringent demands placed on clinical trial documentation and the potentially far-reaching consequences of translation errors. Our teams of specialized translators and multilingual medical experts are adept at navigating the complex terminology and regulatory frameworks that govern life sciences. Whether it’s adhering to guidelines set forth by the International Council for Harmonisation (ICH), conforming to Good Clinical Practice (GCP) standards, or ensuring compliance with regional health authorities (e.g., FDA, EMA, MHRA), we employ rigorous processes and industry-best practices to safeguard the accuracy of every translated document.

By leveraging advanced translation technologies, including Translation Memory (TM) systems, terminology management tools, and secure collaboration platforms, we ensure consistent, high-quality output across all stages of a clinical trial. Coupled with our deep subject matter expertise and unwavering commitment to quality assurance, Sesen’s approach minimizes the risk of misinterpretation and regulatory setbacks. From patient enrollment materials to final regulatory submissions, our mission is to protect patient safety, preserve data integrity, and expedite global study timelines through translations that meet the highest standards of precision and professionalism.

Sesen’s Methodology for World-Class Clinical Translations

At Sesen, every translation project is handled by expert linguists with a proven background in life sciences. Our team includes professional native translators who understand the nuances of clinical research protocols and regulatory language in addition to having extensive experience in medical and pharmaceutical terminology. This specialized knowledge ensures that complex concepts and critical data points remain linguistically accurate and technically precise in every target market.

To maintain unwavering standards of precision, we adhere to ISO-certified workflows (ISO 9001, ISO 13485, ISO 17100) that govern each step of our translation process. After an initial translation, documents undergo independent proofreading and editing by a second expert. In highly sensitive or legally binding materials, we incorporate back translation to verify the original meaning. These rigorous checks minimize the risk of errors and guarantee the highest quality output for clinical trials and related documentation.

Sesen leverages advanced translation technology, including Translation Memory (TM) and terminology management on our intelligent, secure cloud-native translation management platform, to streamline our processes and ensure consistent, high-quality translations across all your project documents. We also develop custom glossaries to capture client-specific product names, branding, and technical terms, which further improves both accuracy and turnaround times. By combining cutting-edge technology with human expertise, we deliver seamless multilingual support for global clinical trials.

Recognizing the sensitivity of clinical trial data, we implement robust security measures and sign NDAs to protect client information at all stages of the project. Our platforms and workflows comply with international data protection regulations, such as GDPR and HIPAA, ensuring that patient information and proprietary study data remain fully secure. With Sesen as your partner, you can be confident that your clinical trial documentation is translated accurately, efficiently, and with the utmost confidentiality.

Linguistic Validation & Cultural Adaptation

High-quality translations in clinical trials go beyond literal word conversion from one language to another. Linguistic validation is crucial for patient questionnaires, Patient-Reported Outcomes (PROs), and other instruments that measure subjective health experiences. This multi-step process typically involves forward-back translation, consensus review, and cognitive debriefing sessions with representative populations. By following industry standards, including guidelines from organizations like the International Society for Pharmacoeconomics and Outcomes Research (ISPOR), Sesen ensures these critical documents retain both conceptual and contextual equivalence across languages.

Equally important is cultural adaptation, where linguistic choices account for local customs, beliefs, and health literacy levels. Patient-facing materials must be easily understood, culturally respectful, and relevant to diverse demographics. This includes selecting appropriate terminology, adjusting date and measurement formats, and considering any potential sensitivities around medical topics. By adapting content in ways that resonate with local audiences, Sesen helps sponsors avoid misinterpretation that could lead to inaccurate data or compromised patient safety.

Together, linguistic validation and cultural adaptation contribute to higher patient engagement and improved retention rates in global studies. Participants who fully comprehend the study requirements and procedures are more likely to adhere to trial protocols and remain committed throughout the study. Ultimately, these best practices safeguard the integrity of clinical data and foster a positive patient experience, two key elements for the success of any international clinical trial.
