About this study
Official title: A Multi-Center Study of Multiple CAR T Cell Therapy for CD7-positive Hematological Malignancies
The purpose of this clinical trial is to assess the feasibility, safety and efficacy of CAR T cell therapy against CD7-positive hematological malignancies using CD7 specific CAR T cells. The study also aims to learn more about the function of CD7 CAR T cells and their persistence in patients of hematological malignancies.

Important Regulatory Notice:
This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.
ClinicalTrials.gov registration alone does not represent legal approval by Chinese health and drug regulatory authorities.
Hematological malignancies including T-cell acute lymphoblastic leukemia (T-ALL), T cell lymphoma (TCL), natural killer cell lymphoma (NKL) and acute myeloid leukemia (AML) are aggressive diseases which may express the early T cell development molecule CD7.
T-ALL represents 15% of childhood and 25% of adult ALL, and T-ALL patients are prone to early disease relapse and suffer from poor outcomes. Several immunophenotypic classifications have been proposed. According to European Group for the Immunological Characterization of Leukemias (EGIL), the presence of cytoplasmic or membrane expression of CD3 defines T-ALL. Four subgroups are proposed: (TI) the immature subgroup or pro-T-ALL is defined by the expression of CD7 and cCD3; (TII) pre-T-ALL also expresses CD2 and/or CD5 and/or CD8; (TIII) or cortical T-ALL shows CD1a positivity; (TIV) finally, mature T-ALL is characterized by the presence of surface CD3 and CD1a negativity.
Over the past few years, T cells modified with lentiviral chimeric antigen receptor (CAR) gene have been studied in different clinical settings. CD7 is a T cell surface protein that plays important role in T cell-B cell interaction in early lymphoid development, displays membrane expression early during T cell development before TCR rearrangement, and persists through terminal stages of T cell development, and a well-known marker for T-ALL. CD7 is considered a promising target for the treatment of T-ALL, TCL, AML and NKL. In this study, we will investigate CD7 CAR-T in combination with alternative targeting CAR-T cells as a new strategy to treat hematological malignancies.
The T cells from patients or transplantation donors will be genetically modified with lentiviral CAR vector to recognize CD7 expressed on the surface of the cancer cells. The engineered T cells will be applied to patients through intravenous delivery.
The purpose of this clinical trial is to assess the feasibility, safety and efficacy of multiple CAR-T cell therapy in hematological malignancies. Another goal of the study is to learn more about the function of CAR T cells and their persistence in the patients.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing CD7-specific CAR gene-engineered T cells in people with T-cell Acute Lymphoblastic Leukemia and T-cell Acute Lymphoblastic Lymphoma, run by Shenzhen Geno-Immune Medical Institute at 1 site 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 7 inclusion and 7 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: opening soon, as of the sponsor's last update on 26 Aug 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?
Contact Lung-Ji Chang, Ph.D (+86 0755-86573763, c@szgimi.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety of infusion (time frame: a year). 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 Aug 2026; AzTrials last refreshed its copy on 26 Oct 2026.
