Full description

This is a single-center, nonintervention, open-label, observational study in subjects who received the study drug (identification code: PRI-724) in Study 1101 to follow up the safety and disease condition of cirrhosis after administration for 12 months.

In Study 1101, one cycle consisted of 2 weeks with one-week continuous i.v. administration of PRI-724 followed by a one-week observation period. Treatment with a total of six cycles (duration of treatment, 12 weeks) was performed.

In this study, the subjects in each cohort in Study 1101 (PRI-724 dose: Cohort 1, 10 mg/m2/day; Cohort 2, 40 mg/m2/day; Cohort 3, 160 mg/m2/day) were followed up and observed for 12 months after administration.

In Study 1101, target number of subjects was 6 subjects in each cohort, a total of 18 subjects. However, the number of registered subjects was 7 subjects in Cohort 1, 7 subjects in Cohort 2, and 2 subjects in Cohort 3, a total of 16 subjects. Safety analysis set was 6 subjects, 6 subjects, and 2 subjects, respectively, a total of 14 subjects. Target number of the subjects in this study was the same as that in Study 1101; however, of the subjects in Study 1101, 5 subjects in Cohort 1 and 3 subjects in Cohort 2 consented to participate in this study (Study 1102).
