A Study of ADR-001 in Patients With Liver Cirrhosis

Patients with decompensated liver cirrhosis (Child-Pugh score; Grade B) caused by Hepatitis C or Nonalcoholic Steatohepatitis are enrolled to the study. In Phase 1, one of 3 doses of AD-MSCs is administered by 1 hour single intravenous infusion. Patients are hospitalized for 1 week and a recommended dose for Phase 2 is determined by the evaluation of the safety and efficacy. In Phase 2, patients with the same disease criteria are enrolled and dosed to investigate the exploratory efficacy and safety.

The safety and efficacy are evaluated until 24 weeks after dosing both in Phase 1 and Phase 2.

• Mesenchymal stem cell (Biological): Phase1 The dose of AD-MSCs are escalated from low to mid and high step by step. Each administration is one time via intravenous infusion for one hour. Phase2 The recommended dose of ADR-001 is administrated once a week 4 times. The administration route and time is same method with Phase 1.

Primary outcomes

• Safety profile of ADR-001 including the incidence of adverse events (Phase 1) [24 weeks]: Safety will be evaluated based on the medical review of adverse event reports and the results of clinical laboratory tests, vital sign, and physical examinations.
• Improvement rate of Child-Pugh score (Phase 2) [24 weeks]: Improvement rate of Child-Pugh score from the baseline will be evaluated.

Secondary outcomes

• Change of liver function evaluated by Child-Pugh score (Phase 1) [24 weeks]: Change of liver function from the baseline will be evaluated by Child-Pugh score.
• Improvement rate of Child-Pugh score (Phase 1) [24 weeks]: Improvement rate of Child-Pugh score from the baseline will be evaluated.
• Improvement rate of Child-Pugh grade (Phase 1) [24 weeks]: Improvement rate of Child-Pugh grade from the baseline will be evaluated.
• Change of liver function evaluated by Child-Pugh score (Phase 2) [24 weeks]: Change of liver function from the baseline will be evaluated by Child-Pugh score.
• Improvement rate of Child-Pugh grade (Phase 2) [24 weeks]: Improvement rate of Child-Pugh grade from the baseline will be evaluated.
• Safety profile of ADR-001 including the incidence of adverse events (Phase 2) [24 weeks]: Safety will be evaluated based on the medical review of adverse event reports and the results of clinical laboratory tests, vital sign, and physical examinations.
