  1. Data are presented as mean (CV%) or, for tmax, as median [range].
  2. aAUC0–∞ for DHA and moxifloxacin; AUC0–24 for PQ; AUC0–t for artemether, lumefantrine and desbuthyl-lumefantrine.
  3. Cmax = maximum plasma concentration; tmax = time to Cmax; AUC0–t = area under the time-concentration curve from time 0 to time of last quantifiable concentration; AUC0–24 = AUC from time 0 to 24 h post-dose; AUC0–∞ = AUC from time 0 to infinity; t½ = half-life; NE = not estimated due to limited sampling to preserve blinding.
