  1. Selection of malaria treatments& diagnostics Presentation by Rémy ProhomRBM Partnership Secretariat, Malaria Medicines & Supplies Services Anglophone PSM Workshop, Nairobi Kenya, 20-24February 2006

  2. Treatments Selection of malaria treatments & diagnostics

  3. ISSUE: • API of artemisinin cannot be produced yet by synthesis • ACTs manufacturing rely then on agricultural raw material production Artemisin-based combination therapies have proven to be the most effective.

  4. Practical solutions • Joint tender WHO-UNICEF to manufacturers of ACTs • Long Term Agreement to ensure low and stable price with selected manufacturers • WHO-UNICEF-IAPSO can order Coartem@ at cost price for public health sector • Partners advocacy to strengthen production and bring more manufacturers in the loop

  5. FDC • Artemether/Lumefantrine • Artesunate + amodiaquine ACTs • Artesunate + SP • Artesunate + mefloquine Combination therapies recommended by WHO Response to increasing resistance WHO Technical Consultation on “Antimalarial Combination Therapy” – April 2001

  6. Artemether/Lumefantrine Treatment of acute uncomplicated malaria due to Plasmodium falciparum or mixed infections including P. falciparum in areas with significant multidrug resistance.

  7. Novartis Pharma AG Artemether/Lumefantrine

  8. Artesunate+Amodiaquine Treatment of acute uncomplicated malaria due to Plasmodium falciparum or mixed infections including P. falciparum in areas with significant drug resistance to Chloroquine or Sulfadoxine-Pyrimethamine.

  9. Artesunate+Amodiaquine 3 Manufacturers currently selected: • CIPLA • IPCA • SANOFI AVENTIS

  10. Artesunate+Amodiaquine Average prices for AS+AQ:

  11. CIPLA Artesunate+Amodiaquine

  12. IPCA PHARMACEUTICALS Artesunate+Amodiaquine

  13. SANOFI-AVENTIS Artesunate+Amodiaquine

  14. Artesunate+Sulfadoxine/Pyrimethamine Treatment of acute uncomplicated malaria due to Plasmodium falciparum in areas where resistance to Sulfadoxine-Pyrimethamine is low (i.e. where the 28-day cure exceeds 80%).

  15. GUILIN Artesunate+Sulfadoxine/Pyrimethamine

  16. Artesunate+Mefloquine • Until now both independent drug WHO GMP approved were purchased separately and given together to the patient; • A co-blister formulation has just been GMP approved and is available on the market, but at a much higher price.

  17. Lead time delivery • Address a request to the manufacturer (or procurement agent) for each and every order for any ACT and get a written answer on the delivery time for your specific order. • Lead time may vary depending of many factors (production site, quantities, packaging, volume and destination) and therefore should be planned much ahead.

  18. Remember about ACTs… • Short shelf life (24 months) • Increased costs • Longer lead time for deliveries • Challenging implementation

  19. Rapid Diagnostic Tests Selection of malaria treatments & diagnostics

  20. Choice of RDTs Considerations for choosing an RDT include: • Plasmodium species to be detected (P. falciparum only, or panspecific) • Shelf -life and temperature stability in intended conditions of storage and use • Ease of use, including format of the test (e.g. cassette, dipstick, card) • Requirement for post-treatment testing of patients • Cost (including transport, training, and quality control) • Sensitivity Good quality assurance processes after purchase are likely to be of greater importance.

  21. Quality assurance Quality assurance system to sustain the reliability of RDTs ManufacturerGood manufacturing practices/control LaboratoryNat/RegionalBatch control District/remote areassensitivity check Final userTraining & supervision Transport & stockMonitoring & temperature control

  22. Procurement issues • Real-time temperature stability data on the product, and accelerated data on the purchased lot • Evidence of successful operational use, or good quality field data on the product • Long-term viability of manufacturer (to ensure continuity of supply) • Evidence of Good Manufacturing Practice /ISO certification (ISO13485:2003 is specific for quality management systems for medical devices) …/…

  23. Procurement issues • Availability of product support • Provision of sample products for assessment and testing for ease of use • Agreement for replacement of products which fail agreed quality control procedures (see above) • Box sizes appropriate to the rate of use of tests in the intended area, to minimize storage time in poor conditions and reduce the need to split boxes.
