5. Study Description

Brief Summary
This study will evaluate the efficacy and safety of a single dose of M5717 plus pyronaridine tetraphosphate in clearing current Plasmodium falciparum infection and protecting against recurrent infections in asymptomatic adults and adolescents. The study will also assess the duration of protection provided by different doses of M5717 plus pyronaridine and the additional contribution of M5717 to the duration of protection using external study data.
