Phase 1, Open-label, Cross-over Study to Investigate the Relative Bioavailability of Pyramax (Pyronaridine-artesunate) in Tablet and Granule Formulations, in Healthy Volunteers

SP-C-017-12

The primary objective of this study is to compare the bioavailability of two formulations (tablets and granules for dispersion) of the antimalarial drug pyronaridine-artesunate \[3:1\] (Pyramax, PA) in healthy adults. The secondary objective is to compare the safety of the two PA formulations and liver function test changes following the first and second administrations.
