duration of trial
The primary endpoint of the study will be the asexual P. falciparum Parasite Clearance Rates (adjusted for molecular testing determining recrudescence, true failures, from reinfection, true cures) at Day 28 in the Parasitologic Per Protocol population.
duration of trial
Secondary Endpoints
