Protocol Defined Assessments

What are protocol defined assessments? 

Protocol defined assessments (PDAs) are specific evaluations or measurements outlined in a clinical study protocol to assess the effectiveness, safety, or other relevant outcomes of an intervention or treatment. These assessments are standardized, meaning they follow predetermined criteria, methodologies, and time points for consistency across the study. PDAs are critical in clinical trials and research studies to ensure data reliability, reproducibility, and the ability to compare results across different studies. 

Why are protocol defined assessments important? 

Protocol defined assessments are essential for ensuring the validity and reliability of clinical research data. By adhering to predefined criteria for measuring outcomes, PDAs provide standardized, high-quality data that help researchers, clinicians, and regulatory bodies make informed decisions about healthcare treatments. This consistency is vital not only for the approval of new therapies but also for improving patient care and outcomes in the long term.
