UNIT 4: Clinical Trial Protocol and Study Documentation
This unit explains the clinical trial protocol as the central scientific and operational document governing the conduct of a clinical study. It also covers the development, control, and regulatory importance of essential study documents required to ensure protocol compliance, subject safety, and data integrity.
Definition
A clinical trial protocol is a written document that describes the objective(s), design, methodology, statistical considerations, and organization of a clinical trial.
The protocol serves as the blueprint for the entire clinical trial and ensures that the study is conducted uniformly across all sites and subjects. It provides clear instructions to investigators, monitors, and other stakeholders, thereby minimizing variability, preventing protocol deviations, and ensuring that the generated data are scientifically valid and ethically acceptable.
