Single oral doses of OPC-184337 tablets or placebo tablets will be administered. Administration of OPC-184337 will start at a dose of 0.25 mg and the dose will be increased incrementally to 0.5, 1, 2, 4, 6, 9, 13.5, and 20 mg, proceeding to each subsequent dose after the safety, tolerability, and pharmacokinetics of OPC-184337 have been confirmed. The trial will not proceed to each subsequent cohort if tolerability is not confirmed. Based on the results of the safety and pharmacokinetic confirmation for each cohort, the trial may proceed to the next cohort after making changes or additions to the planned doses. |
