About this study

Official title: A Phase I/II Clinical Trial to Evaluate the Safety, Tolerability, and Preliminary Efficacy of HCL001 Cell Injection in Patients With Decompensated Cirrhosis

Three sequential dose cohorts are predefined for single administration: Cohort 1 (1.0 × 10⁶ cells/kg), Cohort 2 (2.0 × 10⁶ cells/kg), and Cohort 3 (4.0 × 10⁶ cells/kg). Escalation proceeds from Cohort 1 to Cohort 3 according to a "3 + 3" algorithm, with each subject receiving a single assigned dose. To ensure maximal subject safety, the first subject in every cohort must complete ≥ 14 days of post-dose observation within the DLT evaluation window before additional subjects in that cohort may be dosed. After the last subject in a cohort has completed the entire DLT observation period (from dosing through Day 29), the Safety Review Committee (SRC) will review the cumulative safety data and, by consensus, determine whether escalation to the first subject of the subsequent cohort may commence. Concurrent enrollment into two or more cohorts is prohibited.

Upon completion of the Week 12 assessment in the last subject enrolled in Phase I, one or two dose levels will be selected for Phase II expansion based on the safety and preliminary efficacy data obtained during Phase I.

Read the detailed description

A single SRC will be convened during the Phase I dose-escalation stage to conduct dynamic safety oversight. The SRC will comprise investigators, the Sponsor, and/or medically qualified personnel designated by the Sponsor's delegate (contract research organization [CRO]). Detailed SRC procedures are provided in a separate SRC charter.

Begin with three subjects in the lowest cohort.
If zero of three subjects experience a DLT during the observation period, escalate to the next cohort.
If one of three subjects experiences a DLT, enroll an additional three subjects at the same dose level.
If ≤ 1/6 total subjects in the expanded cohort experience a DLT, escalate to the next cohort.
If > 1/6 experience a DLT, dose escalation is terminated.
If ≥ 2 of the initial three subjects experience a DLT, escalation is stopped; the preceding dose level is declared the maximum tolerated dose (MTD).
If > 1 subject experiences a DLT at any dose level, no further escalation will occur per protocol, and the preceding cohort will be designated the MTD.
If no DLT is observed at the highest predefined dose (4 × 10⁶ cells/kg), the investigator and the Sponsor will jointly determine whether exploration of higher doses is warranted.

Eligible subjects will be randomized to an investigational arm or a control arm.

If only one investigational dose is selected, the randomization ratio will be investigational arm : control arm = 2 : 1.
If two investigational doses are selected, the randomization ratio will be low-dose group : high-dose group : control group = 2 : 2 : 1.

Each investigational cohort will enroll 20-30 subjects, and the control cohort will enroll 10-15 subjects; the control group will receive standard-of-care treatment only. The total anticipated enrollment for Phase II is 30-75 subjects.

Clinical summary

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Detailed description

Begin with three subjects in the lowest cohort.
If zero of three subjects experience a DLT during the observation period, escalate to the next cohort.
If one of three subjects experiences a DLT, enroll an additional three subjects at the same dose level.
If ≤ 1/6 total subjects in the expanded cohort experience a DLT, escalate to the next cohort.
If > 1/6 experience a DLT, dose escalation is terminated.
If ≥ 2 of the initial three subjects experience a DLT, escalation is stopped; the preceding dose level is declared the maximum tolerated dose (MTD).
If > 1 subject experiences a DLT at any dose level, no further escalation will occur per protocol, and the preceding cohort will be designated the MTD.
If no DLT is observed at the highest predefined dose (4 × 10⁶ cells/kg), the investigator and the Sponsor will jointly determine whether exploration of higher doses is warranted.

Eligible subjects will be randomized to an investigational arm or a control arm.

If only one investigational dose is selected, the randomization ratio will be investigational arm : control arm = 2 : 1.
If two investigational doses are selected, the randomization ratio will be low-dose group : high-dose group : control group = 2 : 2 : 1.

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 23 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
