Carine Werder MSF international pharmacist coordinator Geneva, 11th February 2010 Achievements and impacts of WHO prequalification to dateMSF perspective
Public health benefits (1) • Facilitated safe procurement of quality generics, especially for ARVs at the beginning of the HIV pandemics • Demonstrates that WHO norms and standards are achievable • Recognition of generic manufacturers as quality and safe suppliers • Contributed to increased competition and reduction of price
Public health benefits (2) • Encourage the development of new formulations (FDC, new pediatric medicines, etc.) and enabled scale-up • Encourage donors to set up quality assurance criteria for purchase of medicines based on WHO PQ • Capacity building for DRAs
Public health benefits (3) Vaccines: • Complexity of the biological products requires specific expertise • WHO PQ extends access to safe, effective and quality vaccines • Strengthen regulatory authorities in production countries
Impacts from MSF perspective • Extend the list of manufacturing sites with adequate GMP standards, including for other medicines • Reduce the workload for ARV, anti-TB and anti-malarial products to be assessed internally • Prequalification status simplifies drug importation in certain countries • Facilitates the hand-over and integration into national programmes
Continued improvements: • Access to newer treatment options available timely • Prioritization in product assessment (drugs and vaccines) • Extension of WHO PQ (neglected diseases e.g. ampho B liposomal) • Continual extension of available information for purchasers
Additional roles • Quality of medicines in countries with large production capacity (e.g. China) • Advocacy targeted to donors to include stricter QA criteria for the purchase of quality medicines
Diagnostics • The quality of IVDs depends not only on the quality of production, but also of a series of steps towards the end-user. • Critical importance should be made towards the development of strong post-market surveillance system. • Short commercial life spans of IVD (average 5 yrs). • Available funding resources are significantly lower.
Issues with current regulatory practices • Risk level and therefore stringency of regulatory control for IVD based on public health importance of disease in country of submission. (Ex. Malaria diagnostics in non-endemic countries may be approved based on self declaration of manufacturer) • Manufacturers may use same or similar product name for potential different quality levels (eg with and without CE marking) • Approval based on validation by the manufacturer that does not necessarily predict performance of IVDs in the setting of use.
Benefits of Diagnostics PQ • Superiority of PQ Diagnostics programme:takes into consideration the country of use of the IVD, including RLS. Consideration is made based on region-specific reference panels and biological reference materials. • Contribution in shaping new quality standards for IVDs used in RLS, notably through: • technical WG providing information related to the assessment and prequalification of new technologies • Significant contribution in the review of current regulatory and procurement practices towards the development of adequate regulatory requirements and QA standards for procurement.
but... • more work is still needed to establish adequate quality standards and procedures for IVDs • a significant increased support and resources to the PQ Dx programme is needed in order to reach well-defined standards as currently achieved for drugs and vaccines.
