WHO focus on building PV systems in LMIC

Lack of harmonization limits data management and information exchange in LMIC

• Data do exist in LMIC• But data management tools do not exist• Existing tools not of international ICH/E2b standards

• Lack of harmonization• Timely and accurate global exchange of PV information difficult

• Difficult to compare data across ICH and non ICH regions

Vigiflow: WHO solution for PV data management in LMIC

• WHO Solution for implementing ICH standards in non‐ICH countries

• Both a reporting tool as well as a national database

• The stored reports can be extracted as XML files 

• can be transferred to other (E2b)databases 

• A search and statistics module is built into the system

Page 5: WHO Pharmacovigilance strategies of interest to IPC ... · IPC stakeholders Shanthi Pal Medicines Safety Programme Manager ... • WHO Solution for implementing ICH standards in non‐ICH

By using this tool

• LMIC are able to collect reports in standard format compatible with developed countries

• Information exchange between LMIC and global database now possible

• The software update and management occurs centrally, at Uppsala, Sweden

Countries now have their own national database.

Impact of harmonized data management tools

• Data from African countries being pooled• Part of global repository of ADRs• First signal based on quality data of international standards 

from Africa – Amodiaquine‐artesunate antimalarial medicine– Signal of Extrapyramidal symptoms from African PV data– Led to product information update by company

• Involves modest cost to countries: donors to consider funding

Vigiflow supports implementation of  ICDRA recommendations 

ICDRA 2012 recommendations for pharmacovigilance in Member States

• Integration and cohesive systems• Common nomenclature.• Data standards and common reporting formats.

• Data sharing.

But need 'upstream' PV capacity building 

• Focus on how data will be used• Who will use the data: regulators• How to build capacity of regulators for PV in LMIC 

– Data assessment– Decision making– PV obligations of MAH….

• Medicines safety Advisory Committee Recommendation– Develop a PV package for harmonized regulatory functions in LMIC– Leverage AMRH consortium for deliverables

Global Fund: Access to large volumes of ARVs in these vulnerable settings  but no PV

Only 17 out of 430 proposals had any reference to PV

Other Innovations of interest for IPC partners

• Substandard medicinal products• Global threat, but LMIC particularly vulnerable• Impact on medicines procured through global health initiatives

A novel algorithm

• To detect clusters of reports within the WHO Individual Case Safety Reports database ‐ VigiBase™– for lack of effect – based on geographic and temporal patterns– may reflect cases of substandard medicinal products

• To be tested in national databases– For prospective detection of substandard products
