Artemisinin combination therapy (ACT) is the first line to treat uncomplicated Plasmodium falciparum malaria worldwide. Artemisinin treatment failures are on the rise in southeast Asia. Delayed parasite clearance after ACT is associated with mutations of the P. falciparum kelch 13 gene. Patients (N = 148) in five districts of northwest Ethiopia were enrolled in a 28-day ACT trial. We identified a unique kelch 13 mutation (R622I) in 3/125 (2.4%) samples. The three isolates with R622I were from Negade-Bahir and Aykel districts close to the Ethiopia–Sudan border. One of three patients with the mutant strain was parasitemic at day 3; however, all patients cleared parasites by day 28. Correlation between kelch 13 mutations and parasite clearance was not possible due to the low frequency of mutations in this study.
