Malaria medicines and diagnostics WHO/UNICEF TBS Access to medicines 19 November 2009 - Geneva Silvia Schwarte Global Malaria Programme
Outline • WHO Guidelines and Prequalification • Malaria diagnosis • Artemisinin market situation • Resistance and oral artemisinin-based monotherapies
WHO Guidelines for the Treatment of Malaria Malaria diagnosis - Prompt parasitological confirmation by microscopy or alternatively by RDTs is recommended in all patients suspected of malaria before treatment is started. - Treatment solely on the basis of clinical suspicion should only be considered when a parasitological diagnosis is not accessible. Malaria treatment:- artemether – lumefantrine (AL) - artesunate – amodiaquine (AS+AQ) - artesunate + mefloquine(AS+MQ)* - artesunate + sulfadoxine-pyrimethamine (AS+SP) - dihydroartemisinin–piperaquine (DHA-PPQ) Update * not for wide-scale public sector use in Africa

Artemisinin market situationAssured Artemisinin Supply System (A2S2) • Confirmed artemisinin production gap Variable market forecasts, low available stocks or raw material, low profit and low incentives for growers resulting in low plantings, low extraction efficiency • May 2009: UNITAID approves A2S2 Project Loan facility for artemisinin extractors and API suppliers • Urgent action required to meet 2010-2012 forecasts High approval rates GF R7/R8, ongoing R9 and upcoming AMFm launch
Oral artemisinin-based monotherapy Slow progress Pharmaceutical manufacturers 24/73 (33%) withdrew their products 11/73 (15%) intend to comply with WHO ban National Drug Regulatory Authorities45/78 (58%) in line with WHO recommendations 2006 2007 2009 2008 Last updated on 17.11.2009
