VICH Pharmacovigilance Harmonization
Achievements
International harmonization of reporting veterinary
adverse events
GL24 AE Terms, Definitions, Management
GL29 PSUR Standardization, Management
GL42 Data Elements for Submission of AE
GL30 Controlled Lists of Terms (24 lists!)
GL35 Electronic Standards (Data Transfer)

Save The Trees!
3
Information in ADE Report
Trade & Generic Name of Product
Dosage Information (route, date and amount
administered, reason for use, etc.)
Patient(s) Signalment, Overall State of Health
Concomitant Drugs Administered
Description of Adverse Reaction
Animal Outcome
Veterinarian’s opinion
4
GL 35 Electronic Standards for Transfer
of Data
Recommendation to ensure secure transmission
Definition of electronic message structure
Relationships between the data elements
Establishment of additional vocabularies
Business and schema validation rules and field
descriptors specifications for AER data and
wrapper information
5
Considerations for Harmonization
Scope
EMA – drugs and biologics
Japan MAFF – drugs and biologics
FDA CVM – drugs and product problems
USDA CVB – biologics
Canada VDD – drugs
Canada CCVB - biologics
6
Considerations for Harmonization
Standardized Message Format
Provide electronic standards to consider a single message
to transmit GL 42 content to all regions
Format free and available to all users
Decision – must be in line with ISO 27953-1 Health
informatics – pharmacovigilance – individual case
safety reports
Unique descriptive wrappers needed to allow
information acceptance by regionally different IT
systems
7
Considerations for Harmonization
Message Field Lengths and Data Types
8
Considerations for Harmonization
Regional Registrations
FDA CVM
Product has same registration number regardless of varying
strength of tablet
EMA
Product has different registration number with different strength
of tablet
DECISION: use of “Cannot Be Determined” if insufficient
information
9
Considerations for Harmonization
Location Validations
USA
States
UK Counties
Japan Prefectures
Australia - Territories
Canada – Provinces
DECISION: leave the validation at the Regional level
10
Considerations for Harmonization
Telephone Numbers
Japan
+81-3-2364-7781
USA
+1-240-276-9048
Germany
+49-2173-38-4163
England
+44-0-20-7523-7504
DECISION: simple text field with no validation. Format is to
use a + before the country code and dashes in between
numbers
11
Considerations for Harmonization
Time Zones
How to accept a report that is submitted “tomorrow”??
Valid date and timestamp of YYYYMMDDHHMMSS+/-
ZZZZ
**NOTE: HHMMSS represents hours, minutes, and
seconds, and +/-ZZZZ represents GMT offset**
Date of Message creation
Date of Batch creation
12
Harmonized Vocabularies (GL30)
Use a common language for submission
It can be mapped to another language for display in the
individual backend system
Breed examples:
Great Dane vs Deutsche Dogge
Dog124 Deutsche Dogge, Great Dane
Pomeranian vs German Spitz
Dog334 Spitz – German Pomeranian
Mixed breed vs Crossbred
Dog 88 Crossbred Canine/dog
Dog 196 Mixed(Dog)
13
Harmonized Vocabularies
(VeDDRA)
Veterinary Dictionary for Drug Related Affairs
(VeDDRA) terminology for documenting clinical signs
System Organ Class (SOC)
• High Level Term (HLT)
•
Preferred Term (PT)
• Low Level Term (LLT)
Low Level Terms (LLT) are submitted
Allows collection of reported LLT by into higher
category (PT) on searches
14
Preferred Term: Lethargy
Can be reported as several different Low Level Terms:
Decreased activity
Depression
Devitalisation
Dull
Fatigue
Feelings of weakness
Generalized weakness
Lack of awareness
Lack of Response to
owner
Lethargy
Listless
Loss of strength
Reluctant to move
Tiredness
15
Timeline
GL35 basis signed June 2010
Annexed with suggested field lengths and data types
Working Group reviewed documents and comments
Teleconferences June 2011 to June 2012
• Monthly 3 hour teleconferences for 10 months
• One face-to-face meeting to finalize
• Email and break-out teleconferences as needed
• FDACVM Regional Implementation June 2013
16
Number of Veterinary AE Reports Submitted
to FDA CVM by Fiscal Year
17
Number of Companies Reporting Electronically
(June 2013 Revision)
• 16 through Safety Reporting Portal
• 5 directly through Electronic Gateway
18
Percent of Veterinary AE Reports Submitted to
FDA CVM Electronically 2011 – 2014
http://www.accessdata.fda.gov/FDATrack
19
Electronic Submissions
Gateway to Gateway
Automatic population of database
Identification of emerging problems
More efficient data mining capabilities, even if the
report has not yet been reviewed
20
Advantages
Workflow
Periodic cases in real time
Case quality
Closer working relationship with PV partners
Data available for rapid recovery
Data available for data mining and statistics
PV Analyser
21
Quality Assurance Review Sample
(Program began at CVM in October 2013)
Goals:
• Standardized, impartial review of electronically submitted
cases and VedDRA coding
• Maximize receipt of complete and usable case information
• Identify knowledge gaps (such as coding) for evaluation
• Address gaps in future workshops or revisions
22
FDA CVM Pharmacovigilance Scope
• Animal safety
• Drugs and devices (approved or unapproved)
• Serious and non-serious adverse events
• Lack of expected effectiveness
• Off label use/misuse
• Humans reacting after exposure
• Violations of residue levels
• Product problems
• Medication errors
23
• Evaluate signals and trends
•Develop Case Series
• Monitored Adverse Reaction Committee
•Interactive cross center pharmacovigilance forum for discussion of
safety and effectiveness issues of concern
•Label revisions
•Formulation changes
•Product packaging alterations
•Further clinical studies for investigation
•Inform public of perceived risks
•examples: CVM Updates/Dear Doctor letters
24
What Data Mining Can Do:
Signal potential problems quickly
Generate hypotheses regarding potential drug safety
problems
Signal events that might be missed if a pattern is not
expected
25
What Data Mining Cannot Do:
Data mining cannot prove or refute causal associations
between drugs and events.
Data mining simply identifies disproportionality of drug-
event reporting patterns
Data mining cannot replace hands-on clinical review
Individual review of cases is always necessary to explore
data mining signals
