Brief summary
The purpose of this study is to compare the pharmacokinetic profiles of deferitazole after administration of granule and tablet formulations of a deferitazole disodium salt to a capsule formulation of deferitazole magnesium hydroxide salt (reference formulation) in healthy adult subjects.
