Contents • Market share • WHO Prequalification of Diagnostics programme • Remaining challenges • Next steps
Challenges • Multiple regulatory versions for the "same" product • Variable stringency of regulatory review by NRAs • depends on risk classification • if product is for export-only, minimal review • Variable stringency of conformity assessment bodies/inspection agencies • Some inspections may be outsourced to in-country agencies • Differences in QC lot release procedures for CE-marked products for different notified bodies
Challenges • Still poor understanding and implementation of quality management systems at manufacturing site • Inadequate product dossier to demonstrate performance claims including • Product stability • Both in-use and transportation stability • QC and lot release procedure • Customer service in resource-limited settings
Contents • Market share • WHO Prequalification of Diagnostics programme • Remaining challenges • Next steps
Next steps • Amplifying post-market surveillance activities • Should be the onus of the manufacturer, but poorly executed • Role for global/national entities to collect data on poorly performing products & feedback to Mx and other users • Strengthening regulatory capacity in both country of origin and country of sale and use • RDTs are often not widely, if at all, used in the country of origin
Next steps Measure impact of prequalification on Capacity of Mx to consistently produce good quality products Market dynamics Access to new innovative diagnostics Extend prequalification to new product categories of public health value TB, HBsAg, HCV,HIV/syphilis, other multiplexed tests, etc. male circumcision devices
