A Drug Interaction Study to Evaluate the Pharmacokinetics of ASP1517 and Lanthanum Carbonate Hydrate

Pharmacokinetic Study of ASP1517 - Evaluation of the Effect of Lanthanum Carbonate Hydrate on the Pharmacokinetics of ASP1517 in Non-elderly Healthy Adult Male Subjects -

The objective of this study is to evaluate the effect of lanthanum carbonate hydrate on the pharmacokinetics (PK) of ASP1517 in non-elderly healthy male subjects.
