About

The study is a single-center, single-arm, open-label, dose-escalation clinical study, to evaluate the tolerability, safety and preliminary efficacy of CUD005 injection in patients with cirrhosis

Full description

The study was designed according to the 3+3 principle, with a total of 3 dose levels and dose escalation.

Low-dose group: 5.0×107 cells/time; Medium-dose group: 1.5×108 cells/time; High-dose group: 5.0×108 cells/time. Subjects were sequentially placed in 3 different dose groups administered as a single peripheral intravenous dose.

According to the enrollment restriction design, a total of a minimum of 9 subjects are expected to be enrolled, and the final sample size depends on the number of DLT, the number of dose groups ascended before DLT is observed, and the MTD is determined.

Enrollment: 9 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. BMI≤30 kg/m2
2. The results of liver histopathological examination were consistent with the Ishak stage of liver fibrosis ≥3 points；
3. Consent to liver histopathological examination before and after cell therapy (The subject is exempted from liver histopathological examination during the screening period, if he has been performed liver histopathological examination within 2 months before signing the informed consent)；
4. Subjects were able to communicate well with the investigator, cooperate with follow-up work, and understand and comply with the requirements of the study.

6. Subjects with clinically symptomatic ascites or pleural effusions requiring puncture drainage. Or who had received thoracic and ascites drainage within 2 weeks prior to treatment, had may only show a small amount of ascites or pleural effusions on imaging, except in those without clinical symptoms；
7.
