Safety and Tolerability Study of OP-724 in Liver Cirrhosis Patients by HIV/HCV With Hemophilia.

Phase I Clinical Trial of CBP/Beta-catenin Inhibitor OP-724 in Liver Cirrhosis Patients Caused by HIV/HCV Co-infection With Hemophilia. (OP-724-H101)

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

Study Overview

• Status: Completed
• Conditions: Liver Cirrhosis
• Intervention / Treatment: Drug: OP-724

Detailed Description

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.

Intervention / Treatment

Experimental: OP-724 400 mg / 20 mL / vial (20 mg / mL); Dose: [Cohort 1] 140 mg/m2/4 hours (starting dose) , [Cohort 2] 280 mg/m2/4 hours Administration method: In the single administration, the safety of concomitant use with the investigational drug and antiretroviral drug will be confirmed and then the cycle administration will be started. For the single administration, at 14 days before the first cycle of administration, the dose planned for the first cycle with continuous intravenous administration for 4 hours will be administrated once. When an integrase inhibitor is used in combination as a key drug for antiretroviral drugs, it should be administered at the same time as the start of investigational drug administration only after the single administration. For the cycle administration, the continuous intravenous administration for 4 hours twice a week is defined as one cycle, and 12 cycles (12 weeks in total) will be performed.

Drug: OP-724; Twice a week for 4 hours continuous intravenous administration of OP-724.; Other Names: CBP-beta-catenin inhibitor; PRI-724 (former name)

MELD is calculated according to the following formula: * MELD score = 3.78×ln[serum bilirubin (mg/dL)] + 11.2×ln[INR] + 9.57×ln[serum creatinine (mg/dL)] + 6.43	Baseline and 12 weeks after administration
