To evaluate the safety and tolerability of OP-724 in liver cirrhosis patients caused by HIV/HCV co-infection with hemophilia.


This trial is an uncontrolled, open-label, single-center phase I study in liver cirrhosis patients caused by human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection with hemophilia.

Liver cirrhosis patients due to co-infection of HIV and HCV with hemophilia who have a Child-Pugh classification of A or B are included. OP-724 is intravenously administered twice a week (4 hours) for 12 weeks as an administration schedule.

At 14 days before the administration of the first cycle, the dose planned for the first cycle will be administered once by continuous intravenous administration for 4 hours, and the safety and pharmacokinetics will be evaluated from the day of administration to the day after the administration. If an integrase inhibitor is used in combination as a key drug for antiretroviral drugs, its pharmacokinetics will be evaluated at the same time.

A dose escalation study with 2 doses (cohort 1: 140 mg/m2/4hr (starting dose), cohort 2: 280 mg/m2/4hr) will be conducted, and 3 patients in each cohort will be enrolled. Comprehensively investigate the safety and pharmacokinetic data after OP-724 administration, and evaluate the safety and tolerability of OP-724 administration.
