Brief Summary
Malaria is caused by protozoan parasites of the genus Plasmodium and it is the most important parasitic disease in terms of mortality and morbidity. Estimates of 247 million malaria cases and 619.000 deaths worldwide were reported by WHO for the year 2021 (1). Plasmodium falciparum can lead to severe malaria and accounts for 90% of malaria deaths that mainly occur in children below the age of 5 years in Sub-Saharan Africa. A simplified treatment regimen, ideally a single-day cure (or at most 2-day dosing regimen), of uncomplicated malaria due to P. falciparum would be the magic in the antimalarial armamentarium. Improving treatment adherence is one of the key factors in reducing mortality and morbidity and also the transmission of malaria, and such a regimen would substantially increase adherence. To find a new non-artemisinin combination therapy with a shorter regimen, ideally, a single-dose cure, with low resistance potential would be the aim. The two compounds tested here are ZY19489, a triaminopyrimidine, and ferroquine (FQ), a next-generation 4-aminoquinoline. Both compounds show unique features in terms of long half-life, and activity against current drug-resistant strains. Therefore, the main goal of this clinical trial is to assess the safety of the ZY19489-FQ combination given as a 1- or 2-day dose regimen.
