a follow-up evaluation study of pri-724-1101

Conditions: Hepatitis C Virus-infected Cirrhosis

Summary: the purpose of this study to evaluate the safety and efficacy of pri-724 administration in patients with cirrhosis due to hepatitis c by 12-month follow-up.

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).
