Abstract

Objectives: We aimed to assess safety, tolerability, and Plasmodium vivax relapse rates of ultra-short course (3.5 days) high-dose (1 mg/kg twice daily) primaquine (PQ) for uncomplicated malaria because of any Plasmodium species in children randomized to early- or delayed treatment. Methods: Children aged 0.5 to 12 years with normal glucose-6-phosphate-dehydrogenase (G6PD) activity were enrolled. After artemether-lumefantrine (AL) treatment, children were randomized to receive PQ immediately after (early) or 21 days later (delayed). Primary and secondary endpoints were the appearance of any P. vivax parasitemia within 42 or 84 days, respectively. A non-inferiority margin of 15% was applied (ACTRN12620000855921). Results: A total of 219 children were recruited, 70% with Plasmodium falciparum and 24% with P. vivax. Abdominal pain (3.7% vs 20.9%, P
