MedDRA Terminology - a brief overview and update Andrea Neal, DMD, MPH Office of Post-Marketing Drug Risk Assessment Center for Drug Evaluation and Research
MedDRA Terminology • ICH Harmonized Medical Terminology for Regulatory Purposes • An International Medical Terminology (IMT) • Multi-axial terminology built upon 5-level Hierarchical Structure
Current Situation Makes Exchange of Information Difficult • Research Institutions and Practitioners • create multiple submissions in various terminologies • Industry / CROs • receive reports in various terminologies • FDA report evaluators • receive submissions coded in various terminologies
Benefits of the Standard Terminology • Improve regulatory communications between all involved parties • Facilitate consistent coding and decrease information loss, thereby enhancing quality review • Decrease time spent by reviewers on data normalization (cont…)
Benefits of the Standard Terminology • Decrease submission time for INDs/NDAs • Improve product labeling • Facilitate shift to electronic submissions - pre & post • Improve epidemiological study on global scale
ICH guiding principles • Build from existing terminologies to maximize compatibility • Focus on international community needs • Ensure worldwide use through collaboration and participation in development • Ensure mechanisms and structures to enable translation into many languages • Ensure long-term maintenance
Terminologies Included • MCA Medical Terminology • COSTART (5th ed.) • WHO-ART (96:4) • J-ART (1996) • ICD-9 • ICD-9-CM (4th revision) • HARTS (release 2.2)
MedDRA Terminology • Progression from version 1.0 to version 2.0 • Same 5-level hierarchical structure • Thousands of additional terms • Complete re-write of several SOCs
Scope of MedDRA • Diseases • Diagnoses • Signs • Symptoms (cont…..)
Scope of MedDRA (cont.) • Therapeutic indications • Investigation names & qualitative results • Medical & surgical procedures • Medical, social, family history
Scope of possible, future expansion: • drug /product terminology • equipment / device / diagnostic prod. • study design • patient demographic terms • device failure • population qualifiers (i.e. rare, frequent) • descriptors of severity
Use throughout regulatory cycle • Clinical Studies • Adverse Event/Reaction Reporting • Regulatory Submissions • Regulated Product Information
Adverse Event Reporting in CDER - changing environment • Rapidly growing # reports - 200,000 + / yr. • Faster review cycle • More complex pharmaceuticals • Aging population using more pharmaceuticals
MedDRA Implementation: FDA • MedDRA implemented Nov. ‘97 • Launch of AERS (Adverse Event Reporting System) - January ‘98 • All Adverse Event Reports entered to database coded in MedDRA
ANPRM Issued 11/5/98 • For Electronic ADR Reporting • To Implement: • ICH M1 (MedDRA) • ICH M2 (Electronic Transmission Standards) • ICH E2B (Safety Report Data Elements) • Goal of Paperless Environment by 2002
ANPRM (cont.) • Comments specifically solicited regarding: • whether exemptions should be granted • if so, their basis • cost benefits / cost burdens • timeframes for implementing requirement • Comments received and being considered
Next Steps • Continue implementation on post-market side • Prepare NPRM for Electronic ADR Reporting • Lend CDER/CBER experience to the implementation of MedDRA on pre-market processes
