NCT ID: NCT01048788

Last Updated: 2016-04-11

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 51 participants

Brief Summary

OPC-41061 will be orally administered at 7.5 mg/day for 7 days to cirrhosis patients with ascites despite having received conventional diuretic therapy. Based on the change in body weight, on Day 7 it will be decided whether to continue administration at the same dose or to increase the dose, and then OPC-41061 will be orally administered for an additional 7 days at either 7.5 mg/day or, if diuretic effect for the initial 7-day administration is insufficient, at an increased dose of 15 mg/day. Plasma drug level, efficacy, and safety of OPC-41061 by 14-day repeated administration will be investigated.
