The Medical Dictionary for Regulatory Activities (MedDRA) is an internationally recognized terminology system that provides a consistent and standardized language for the reporting and classification of medical events. It is a critical component in ensuring clear communication between different stakeholders in the drug regulatory process.
MedDRA comprises a hierarchical structure with five levels, where Preferred Terms (PTs) are used to describe specific medical events and are grouped under System Organ Classes (SOCs), which categorize events according to the organ system affected. This organization helps to streamline data analysis and improve the accuracy of safety assessments.
For example:
- SOCs:
- Cardiovascular System
- Gastrointestinal System
- PTs:
- Myocardial infarction
- Abdominal pain
Terminology for Adverse Events Classification
In the context of regulatory submissions and safety reviews, the classification of adverse events plays a crucial role. Severity of an event refers to the intensity or degree of the event, rather than its seriousness. It is typically categorized as mild, moderate, or severe:
- Mild: The event causes minimal discomfort and does not interfere significantly with the subject’s daily activities.
- Moderate: The event causes sufficient discomfort to interfere with the subject’s daily activities, requiring intervention or treatment.
- Severe: The event causes significant impairment or incapacitating effects, which may require medical intervention or hospitalization.
The use of standardized terminology such as MedDRA, PTs, and SOCs allows for efficient and accurate communication of safety information between investigators, sponsors, and regulatory agencies. By adhering to these data and terminology standards, stakeholders can ensure that the Reference Safety Information (RSI) accurately reflects the known safety profile of a drug, enabling proper risk assessment and management throughout the clinical development process.
