Brief Summary

To investigate safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity in Japanese and Caucasian healthy adult male subjects when ONO-4685 is administered as a single-dose by intravenous infusion.

Detailed Description

To investigate safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity when ONO-4685 is administered by single-dose intravenous continuous infusion in Japanese and Caucasian healthy adult male subjects. In addition, in Japanese healthy adult male subjects, to investigate dosing condition of Keyhole limpet hemocyanin (KLH) and to investigate safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity when ONO-4685 is administered by single-dose intravenous continuous infusion after treating with KLH.
