Title: A Phase III Comparative, Open-label, Randomised, Multi-centre Study to Assess the Efficacy of Pyronaridine Artesunate (180:60mg) Versus Mefloquine (250mg) Plus Artesunate (100mg) in Children & Adult Patients With Acute Falciparum Malaria
Brief Summary: The primary objective of this phase III clinical study is to compare the efficacy and safety of the fixed combination of pyronaridine artesunate (Pyramax®, PA) with that of the combination of mefloquine plus artesunate (MQ + AS) in children and adults with uncomplicated P falciparum malaria in South East Asia, India and Africa.
