    Abstract:
    BACKGROUND: Pyronaridine-artesunate is a novel artemisinin-based combination therapy. The efficacy and safety of pyronaridine-artesunate were compared with artemether-lumefantrine for the treatment of uncomplicated Plasmodium falciparum malaria in children. METHODS: This phase III open-label randomized controlled non-inferiority trial was conducted in Western Kenya. Children aged 6 months to ≤ 12 years with a bodyweight > 5 kg and microscopically confirmed P. falciparum malaria were randomly assigned in a 1:1 ratio to orally receive pyronaridine-artesunate or artemether-lumefantrine, dosed according to bodyweight, for 3 days. RESULTS: Of 197 participants, 101 received pyronaridine-artesunate and 96 received artemether-lumefantrine. The day-28 adequate clinical and parasitological response in the per-protocol population, PCR-corrected for reinfections, was 98.9% (93/94, 95% CI 94.2-99.8) for pyronaridine-artesunate and 96.4% (81/84, 95% CI 90.0-98.8) for artemether-lumefantrine. Pyronaridine-artesunate was found to be non-inferior to artemether-lumefantrine: the treatment difference was 2.5% (95% CI - 2.8 to 9.0). Adverse events occurred in 41.6% (42/101) and 34.4% (33/96) of patients in the pyronaridine-artesunate group and the artemether-lumefantrine group, respectively. No participants were found to have alanine or aspartate aminotransferase levels > 3 times the upper limit of normal. CONCLUSIONS: Pyronaridine-artesunate was well tolerated, efficacious and non-inferior to artemether-lumefantrine for the treatment of uncomplicated P. falciparum malaria in Kenyan children. Results are in line with previous reports and inclusion of pyronaridine-artesunate in paediatric malaria treatment programmes should be considered.
