Title: A Phase III Comparative (Double-blind, Double-dummy) Randomised, Multi-centre Study to Assess the Efficacy of Pyronaridine Artesunate (180:60mg) Versus Coartem® (Artemether Lumefantrine) in Children & Adult Patients With Falciparum Malaria
Brief Summary: The primary objective of this phase III study is to compare the efficacy and safety of the fixed combination of pyronaridine artesunate (Pyramax®, PA) with that of Coartem® (artemether lumefantrine, AL) in children and adults with uncomplicated P falciparum malaria in Africa and South East Asia.
