Condition or disease Intervention/treatment Phase
Hepatitis C Hepatitis B Liver Cirrhoses Drug: PRI-724 Phase 1 Phase 2

Detailed Description:

【Phase I Phase】 To evaluate safety and pharmacokinetics when PRI-724 is administered to patients with HCV or HBV liver cirrhosis , and determine the recommended dose of PRI-724.

【Phase IIa phase】 To evaluate the efficacy and safety of the recommended dose of PRI-724 administered to patients with HCV or HBV liver cirrhosis.

Arm Intervention/treatment
Experimental: PRI-724

Dose: 140, 280, 380 mg / m 2/4 hr

Administration method:

【Phase I Phase】 (Level 1) 140 mg / m 2/4 hr (Level 2) 280 mg / m 2/4 hr (Level 3) 380 mg / m 2/4 hr Twice weekly, continuous 4-hour intravenous administration (tolerance of administration time: ± 15 minutes). This is one cycle and 12 cycles (12 weeks in total) are carried out. However, in Phase I phase, single dose is administered on Day - 7 (tolerance: - 7 days).

【Phase IIa phase】 Continuous intravenous administration for 4 hours twice a week at the recommended dose determined in Phase I. This is one cycle and 12 cycles (12 weeks in total) are carried out.

Drug: PRI-724
twice a week for 4 hours continuous intravenous administration of PRI-724
Other Name: CBP-b-catenin inhibitor




Primary Outcome Measures :
  1. Serious side effect expression rate [ Time Frame: 12 weeks after administration ]
    (Phase I)Serious side effect expression rate

  2. liver tissue fibrosis area ratio by liver biopsy [ Time Frame: 12 weeks after administration ]
    (Phase II) Amount of change from the baseline in liver tissue fibrosis area ratio by liver biopsy at 12 weeks after administration


Secondary Outcome Measures :
  1. Adverse Event Expression Ratio [ Time Frame: 12 weeks after administration ]
    Adverse Event Expression Ratio after PRI-724 treatment

  2. Percentage of occurrence of side effects [ Time Frame: 12 weeks after administration ]
    Percentage of occurrence of side effects after PRI-724 treatment

  3. Pharmacokinetic parameter [ Time Frame: 12 weeks after administration ]
    Maximum Plasma Concentration (Cmax)

  4. liver stiffness from Fibro Scan [ Time Frame: 12 weeks after administration ]
    Amount of change from measurement of liver stiffness by baseline from Fibro Scan at 12 weeks after administration

  5. Child Pugh score [ Time Frame: 12 weeks after administration ]
    Amount of change from baseline of Child-Pugh Score at 12 weeks after administration Child Pugh score (scale range 5-15) is obtained by adding the score for each parameter (encephalopathy, ascites, bilirubin, albumin, PT or INR).

  6. MELD score [ Time Frame: 12 weeks after administration ]

    Amount of change from baseline for MELD score at 12 weeks after administration

    The Model for End-Stage Liver Disease (MELD) is a scoring system for assessing the severity of chronic liver disease and uses the subject's values for total bilirubin, serum creatinine, and the international normalized ratio (INR) for prothrombin time to predict survival. MELD is calculated according to the following formula:

    MELD = 3.78×ln[serum bilirubin (mg/dL)] + 11.2×ln[INR] + 9.57×ln[serum creatinine (mg/dL)] + 6.43


  7. modified Histological Activity Index (HAI) by liver biopsy [ Time Frame: 12 weeks after administration ]
    Change amount from baseline of modified Histological Activity Index (HAI) by liver biopsy at 12 weeks after administration


Other Outcome Measures:
  1. Serum fibrosis marker level(s) [ Time Frame: 12 weeks after administration ]
    Changes of level

  2. Ascitic fluid level [ Time Frame: 12 weeks after administration ]
    Changes of level
