The Ethiopian Public Health Institute (EPHI), the research arm for the Ministry of Health (MOH), has been studying the safety and efficacy of antimalarial drugs for the past two decades. The national malaria diagnosis and treatment guideline of Ethiopia states first-line treatment for uncomplicated Plasmodium falciparum (P. falciparum) infection is artemether-lumefantrine (AL) with a single dose of primaquine (PQ) and for uncomplicated P. vivax infection chloroquine (CQ) with 14 days of PQ. This study aimed to evaluate the therapeutic efficacy of AL plus a single low dose of PQ for uncomplicated P. falciparum malaria and CQ plus 14 days of PQ for uncomplicated P. vivax malaria in six sentinel sites of Ethiopia.\n\nMethods: This study will be conducted from October 2026 to June 2027 in six sentinel sites. A minimum of 100 patients each with uncomplicated P. falciparum or P. vivax malaria aged 6 months and above, will be enrolled at each of the six study sites and followed for 28 days for P. falciparum and 42 days for P. vivax for adequate clinical and parasitological response. Patients with microscopically confirmed P. falciparum mono-infection will be assigned to receive AL + PQ, and those with microscopically confirmed P. vivax mono-infection will be assigned to receive CQ + PQ. Clinical, parasitological, and hematologic parameters will be monitored for P. falciparum and P. vivax infections for up to a 28\u002F42-day follow-up period and used to evaluate drug efficacy. Kaplan-Meier method survival analysis and pertinent descriptive analysis will be conducted using STATA considering P \\\u003C 0.05 as statistically significant.
