Drug Combinations of Atovaquone-Proguanil (AP) With ACT

Summary

Investigators are conducting this study due to recent reports of many of existing malaria drugs becoming less effective for treatment of malaria. The drugs may not always kill all the parasites, therefore not all patients with malaria are being cured. The main objective of the study is to find out which malaria drugs and what drug combinations are still effective in Cambodia, an area of multi-drug resistance where 4-5 artemisinin-based combination therapies have shown inadequate response, below that established by the World Health Organization (WHO). New drug combinations (taking more than one drug for malaria at the same time), as long as well tolerated, can provide cure in patients that harbor parasites not responsive to standard first-line medications. Human genetic testing will be done to identify patients who may have suboptimal response to treatments and to study the differences in human gene expression to explain why some persons are at higher risk of complications during treatment. Markers of drug resistance to commonly used antimalarial drugs will also be evaluated and shared with national malaria program (CNM) to better guide future malaria treatment decisions in Cambodia.
