Summary:

      The primary objective of this study is to determine the bioequivalence of the combination of
      pyronaridine and artesunate (180:60mg) to-be-marketed tablet to the clinical trial reference
      tablet administered as a single total dose of 720:240 mg in healthy adults. The secondary
      objective is to assess the safety of the two formulations.
