About this study

This is a multi-center, open-label, non-randomized, phase 1/2 study of anti-CD5 CAR-T cell therapy in patients with CD5+ relapsed or refractory T-cell malignancies. A bayesian optimal interval (BOIN) 12 design will be used to explore the optimal biological dose (OBD) from starting dose level 1: 1×10^6 (±20%) to dose level 2: 2×10^6 (±20%) in three cohorts (autologous, previous-transplant-donor or newly matched donor-derived CD5 CAR T cells). If the manufactured cells are not sufficient to meet the preassigned standard dose criteria, patients will be given infusion at a low dose level of 5×10^5 (±20%) /kg. The primary objective is to evaluate the safety and tolerability of CD5 CAR T cell therapy in subjects, determine the OBD and recommend phase 2 dose (RP2D) in phase 1, and evaluate the efficacy of CD5 CAR T cell therapy in phase 2. The primary endpoint is the type and incidence of dose-limiting toxicity (DLT) within 28 days, and the incidence and severity of adverse events (AEs) within 30 days after CD5 CAR T-cell infusion in phase 1, the best overall response (BOR) at 3 months (± 1 week) after CD5 CAR T-cell infusion in phase 2. A total number of 54 subjects will be enrolled.

    Measured: 3 months (± 1 week) after CD5 CAR T cell infusion

  5. Phase 2-Objective response rate (ORR)

    Objective response rate (ORR) is the percentage of subjects who have achieved CR, CRi or PR based on the National Comprehensive Cancer Network (NCCN) Guidelines Version 3.2023 of Acute Lymphoblastic Leukemia.

    Measured: 1 months and 3 months after CD5 CAR T cell infusion

  6. Phase 2- The incidence and severity of AEs

    Measured: Up to 2 years

  7. Phase 2- Progression free survival (PFS)

    Progression-free survival (PFS) is defined as the time from the initial CD5 CAR T cell infusion to the date of progression or death for any cause.

    Measured: Up to 2 years

  8. Phase 2- Overall survival (OS).

    Overall survival (OS) is defined the time from the initial CD5 CAR T cell infusion to death for any cause.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Autologous CD5 CAR T-cells, Previous stem-cell transplantation (SCT) donor-derived CD5 CAR T-cells and Newly matched donor-derived CD5 CAR T-cells in people with T-Cell Acute Lymphocytic Leukemia and Acute Lymphoblastic Leukemia, in Relapse, run by Beijing GoBroad Hospital at 4 sites in China.

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 3 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 26 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

Contact Shaocong Miao (86+18831006667, miaosc@gobroadhealthcare.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1-The incidence and type of dose-limiting toxicity (DLT) (time frame: 28 days after CD5 CAR T cell infusion). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Nov 2025.
