1 Introduction to MedDRA® (Medical Dictionary for Regulatory Activities)
MedDRA® is a registered trademark of the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA)

2 What is MedDRA? Med = Medical D = Dictionary for R = Regulatory
A = Activities

3 Objectives for MedDRA Development
To provide: An international multi-lingual terminology Standardized communication between industry and regulators Support of electronic submissions Application through all phases of the development cycle

4 Objectives for MedDRA Development (cont)
To provide (cont): Classification for a wide range of clinical information Support for multiple medical product areas A terminology that saves time, resources, and money

5 MedDRA Definition MedDRA is a clinically-validated international medical terminology used by regulatory authorities and the regulated biopharmaceutical industry. The terminology is used through the entire regulatory process, from pre-marketing to post-marketing, and for data entry, retrieval, evaluation, and presentation. e.g. in full regulatory process: Clinical studies - Reports of spontaneous adverse reactions and events - Regulatory submissions - Regulated product information

6 MedDRA Hierarchy System Organ Class (SOC) High Level Group Term (HLGT)
High Level Term (HLT) Preferred Term (PT) Lowest Level Term (LLT)

7 System Organ Classes Blood and lymphatic system disorders
Cardiac disorders Congenital, familial and genetic disorders Ear and labyrinth disorders Endocrine disorders Eye disorders Gastrointestinal disorders General disorders and administration site conditions Hepatobiliary disorders Immune system disorders Infections and infestations Injury, poisoning and procedural complications Investigations Metabolism and nutrition disorders Musculoskeletal and connective tissue disorders Neoplasms benign, malignant and unspecified (incl cysts and polyps) Nervous system disorders Pregnancy, puerperium and perinatal conditions Psychiatric disorders Renal and urinary disorders Reproductive system and breast disorders Respiratory, thoracic and mediastinal disorders Skin and subcutaneous tissue disorders Social circumstances Surgical and medical procedures Vascular disorders

8 MedDRA Codes Each MedDRA term assigned an 8-digit numeric code
The code is non-expressive Codes can fulfill a data field in various electronic submission types (e.g., E2b) Initially assigned alphabetically by term starting with New terms are assigned sequentially Supplemental terms are assigned codes

9 MedDRA Codes (cont) Terms are being renamed
When terms are renamed, the code number is reused for the renamed term Renaming has been done for spelling errors, hyphenation, and parenthesis changes When HLT or HLGT terms are removed from the terminology, they are deleted – NOT moved to the LLT level and made non-current

10 Non-Current Terms Non-current terms are flagged at the LLT level within MedDRA Not recommended for continued use Retained within the terminology to preserve historical data for retrieval and analysis Terms very vague, ambiguous, out-dated, truncated, or misspelled Terms derived from other terminologies that do not fit MedDRA rules

11 A Multi-Axial Terminology
Multi-axial = the representation of a medical concept in multiple SOCs Allows terms to be grouped by different classifications Allows retrieval and presentation via different data sets Allows an automatic assignment of predefined term groupings

12 A Multi-Axial Terminology (cont)
SOC = Respiratory, thoracic and mediastinal disorders SOC = Infections and infestations HLGT = Respiratory tract infections HLGT = Viral infectious disorders HLT =Viral upper respiratory tract infections HLT = Influenza viral infections PT = Influenza

13 A Multi-Axial Terminology (cont)
SOC = Endocrine disorders SOC = Metabolism and nutrition disorders HLGT = Glucose metabolism disorders (incl diabetes mellitus) HLT = Diabetes mellitus (incl subtypes) PT = Diabetes mellitus
