14. Informal Consultation to Consolidate the Regional Response to Address Artemisinin Resistance and Substandard Antimalarial Medicines in the GMS, Bangkok, Thailand, 24-26 April 2012 Working definition of As R The working definition of artemisinin resistance is based on clinical and parasitological outcomes observed during routine therapeutic efficacy studies of ACTs and clinical trials of artesunate monotherapy:  an increase in parasite clearance time, as evidenced by  10% of cases with parasites detectable on day 3 after treatment with an ACT (suspected resistance)  Or  treatment failure after treatment with an oral artemisinin-based monotherapy with adequate antimalarial blood concentration, as evidenced by the persistence of parasites for 7 days, or the presence of parasites at day 3 and recrudescence within 28/42 days (confirmed resistance).

19. Informal Consultation to Consolidate the Regional Response to Address Artemisinin Resistance and Substandard Antimalarial Medicines in the GMS, Bangkok, Thailand, 24-26 April 2012  Limited access to (and use of) quality diagnosis and quality medicines including adherence to Treatment by vulnerable population (mobile pop and migrants, ethnic groups … ) or due to occupational risk situations (development projects, forest, …)  Marketing and Use of Monotherapies, Counterfeits and Substandard Medicines  Private Sector Engagement to adhere to best practices  Lack of direction and coordination to boost harmonized activities  Lack of support to operational research (alongside with programmes)  Declining interest of Governments and Donors (competing priorities) Potential Contributing Factors to As resistance and impacting on Malaria Elimination Possibly better addressed through a Regional Response
