Phase 1
Conditions
Volume overload in heart failure
Registration Number
JPRN-jRCT2071200061
Lead Sponsor
Kim Seongryul
Brief Summary

Single and multiple oral administrations of OPC-131461 in healthy adult male subjects, the mean Cmax and AUC increased in a dosedependent manner, and the median tmax and mean t1/2,z were 1.50 to 4.00 hours and 18.5 to 29.8 hours, respectively, suggesting that OPC-131461 was quickly absorbed and had a long half-life.The events with a high incidence were common to both parts of the trial and may have been due to the pharmacological effects of OPC-131461, but the severity of the events were all mild.
