Brief Summary   Malaria is the second most common infectious disease globally. Although therapies are available for treating uncomplicated malaria, rising cases of drug resistance pose a big threat to the aim of completely eradicating the parasite. ZY-19489 is a new antimalaria drug developed by Zydus Lifesciences Ltd and is studied both in preclin-ical and clinical settings. Clinical studies have been con-ducted in patients with uncomplicated P. falciparum malaria, and these studies have suggested that ZY-19489 is efficacious as well as safe. Although in vitro evidence suggests that ZY-19489 has activity against blood stages of P. vivax, no clinical evidence is available for the activity of ZY-19489 against P. vivax malaria. Hence, this study aims to examine the efficacy, safety, and tolerability of orally administered ZY-19489 in pa-tients with uncomplicated P. vivax malaria.
