In the Asia-Pacific region, the monitoring of the efficacy of antimalarial drugs including artemisinins and artemisinin-based combination therapies (ACTs) has become a routine activity of the national malaria programs using a standardized WHO therapeutic efficacy study (TES) protocol. It aims to identify early signs of resistance of recommended treatment regimens to drive evidence-based review and update of a country's national drug policy. The 4th Meeting of the BBINS Malaria Drug Resistance Monitoring Network (Bangladesh, Bhutan, India, Nepal and Sri Lanka) convened in New Delhi, India on 15–16 October 2019. The discussions highlighted the results of therapeutic efficacy studies including updates on molecular markers for drug resistance, showing that the 1st-line artemisinin-based combinations therapies (ACT) in all countries are currently effective against both P. falciparum and P. vivax malaria; countries to further strengthen The Meeting of the Bangladesh, Bhutan, malaria microscopy QA; and adopt iDES for monitoring of malaria drug efficacy in areas with low malaria cases as part of the programme's elimination surveillance activities. India, Nepal, Sri Lanka (BBINS) Also discussed were workplans for continuing studies over the next two years.
