Update and future directions for prequalification of medicines WHO HQ, Geneva, 4 February 2008 Dr Lembit Rägo Coordinator Quality Assurance and Safety: Medicines Medicines Policy and Standards Health Systems and Services
Prequalification of medicines Established in 2001 Started with HIV/AIDS products, later TB, malaria and selected reproductive health products were added Based on WHO normative guidelines, widely discussed and transparent Open to both innovative and generic medicines Carried out by global pool of regulators for the benefit of all stake holders – outcome list of prequalified products as a public good Capacity building and training important component Continues to face old, but also meets new challenges
Which medicines and why PQ Programme deals with? Application to include a product on Expression of Interest (EOI) Lists published comes from WHO disease oriented programs Products should be of high public health value Products must be in line with WHO treatment guidelines Products must be in line with Essential Medicines List Rare exceptions from these principles, if justified
Constantly updated web site:
Highlights of 2007 Total number of prequalified products reached 156 Increased work load for maintenance Relatively small number of new products prequalified "New comers" – usually low quality submissions Applicants "fatigue" – not enough new products applied Boosting quality control laboratories prequalification Strengthening programme, increasing transparency Substantially increased delivery of trainings and technical assistance (+100% increase)
Trainings
News example
HIV/AIDS In total 360 assessment reports were written in 2007
TB products In total 87 assessment reports were written in 2007
Inspections – finished product manufacturers Inspections of finished products manufacturers increased during 2007 reaching 26
Submission of product dossiers HIV TB Malaria NO NEW SUBMISSIONS in 2007 of some priority products: -2nd-line anti-tuberculosis products -paediatric anti-retroviral products
Proactive steps in 2007 – 2nd-line TB Scientific advice on design appropriate of bio- equivalence studies Detailed guidance to perform dissolution studies to implement biowaiver (to replace BE- study, if feasible) Development of Pharmacopoeia monographs for anti-tuberculosis medicines Situation (gap) analysis on the potential of tb- manufacturers to develop new products
Proactive steps in 2007 – Malaria Proactive working with applicants (pre- submission review, reminders, coordinate submission of additional data, meetings for solving problems) Scientific advice on design appropriate of bio- equivalence studies Research (adverse reactions database, complicated quality issues) Development of Pharmacopoeia monographs for antimalarial medicines
Proactive steps in 2007– paediatric medicines To support appropriate dosage and formulation design by manufacturers: First Essential Medicines List for Children WHO guidance on preferred ARV medicines for the children; model to design proper strengths of fixed-dose combination products for different weight/age Consultation with other regulators (such as US FDA) Two training courses on "Development of Paediatric Medicines" in 2007, third prepared for India in April 2008
To ensure sustainability of supplies of good quality priority products: challenges Continue developing WHO standards and guidelines Guidance on development and analytical control of TB and antimalarial medicines Close the information gap for paediatric medicines Implement comprehensive sampling and testing programme Develop a comprehensive programme for providing technical assistance to potential new manufacturers If manufacturers are to be persuaded to make the human and technological investments needed to enhance quality of medicines, financial incentives must be built into procurement mechanisms.
Future directions: short-term Technical guidance, regulatory advise and technical assistance to manufacturers has to increase Increasing efficiency: shorter timelines, pro-active follow- up and communication for priority products Continuing human resource development – new assessors/inspectors identified and trained Trainings organized for assessors to achieve better consistency and the same level of technical skills Continuing developing capacity building element in the programme Second rotational post to be considered Increased communication and information exchange with regulators (both from well resourced and less resourced countries)
Future directions: long-term Long-term strategy to be finalized during 2008 Promoting and facilitating production of quality medicines in developing countries continued Structured co-operation with regulatory agencies further developed to avoid duplications using several tools Memorandums of understanding, confidentiality agreements Collaboration agreements Promoting harmonization continued - potential to work with some regional harmonization initiatives to be explored Exploring potential of contracting certain functions to national regulators/quality control laboratories
Instead of conclusions Prequalification - a good engine to pull quality of medicines into international agenda It challenges the still existing reality "poor quality medicines for poor" How best keep it going as huge unfinished agenda is ahead?
