Plain-language summary

Phase I (Single Administration, Randomized, Double-blind, Dose Escalation)Primary Objective: To evaluate the safety and tolerability of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis, and to determine the safe clinical dose.Secondary Objective: To evaluate the preliminary efficacy of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis, providing a basis for the design of subsequent clinical trial protocols.Exploratory Objective: To evaluate the pharmacokinetic characteristics and immunogenicity of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis.Phase II (Multiple Administrations, Randomized, Double-blind, Dose Expansion)Primary Objective: To evaluate the preliminary efficacy of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis.Secondary Objective: To evaluate the safety of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis.Exploratory Objective: To evaluate the pharmacokinetic characteristics and immunogenicity of Human Umbilical Cord Mesenchymal Stem Cell Injection in patients with decompensated hepatitis B cirrhosis.

Inclusion Criteria: * Aged between 18 and 75 years (inclusive) at screening, regardless of gender. * Diagnosed with decompensated hepatitis B cirrhosis with a history of portal hypertension-related complications according to the Guidelines for the Diagnosis and Treatment of Cirrhosis (2019 Edition). * After at least 3 months of strict conservative medical treatment (including antiviral therapy with nucleos(t)ide analogues, hepatoprotective, symptomatic, and nutritional support therapy), there has been no significant alleviation of cirrhosis symptoms or improvement in quality of life scores, and the investigator deems the subject suitable for stem cell therapy. * HBV DNA level \< 2 × 10³ IU/mL at screening. * Not suitable for liver transplantation, or lacking a liver donor source. * Both the subject and their partner have no plans for pregnancy from screening until 6 months after the end of the trial and agree to use effective non-pharmacological contraception during the trial period. * Fully understand the informed consent form, voluntarily participate in the trial, and sign the informed consent form. Exclusion Criteria: * Cirrhosis due to other causes, such as alcoholic hepatitis, hepatitis C virus infection, autoimmune hepatitis, and metabolic dysfunction-associated steatotic liver disease (MASLD). * Child-Pugh score \> 12 points. * History of malignancy in the liver or other organs, or a family history of liver malignancy in first-degree relatives. * The investigator ju…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
