This is a single-center, open-label, single-arm study to evaluate the primary safety and efficacy of anti-CD7 chimeric antigen receptor(CAR)-modified T cells(CAR7-Ts) in patients with relapsed or refractory T lymphoid malignancies.
Chimeric antigen receptor-T cells (CAR-T) have made breakthroughs in the treatment of B-cell tumors, especially refractory/relapsed acute B lymphocytes. CD7 is a transmembrane glycoprotein expressed by T cells and natural killer cells and their precursors; it is also expressed in >95% of lymphoblastic T-cell leukemias and lymphomas . CD7 was previously evaluated as a target for immunotoxin-loaded antibodies in patients with T-cell malignancies, but tumor responses were limited.
Enhancing the potency of CD7-directed cytotoxicity by substituting donor-derived CAR-T cells for a monoclonal antibody would augment the efficacy of CD7-targeted therapy in patients with T-cell malignancies. To prepare CAR7-T cells, CD7 expression is suppressed on donor-derived T cells by unique blocking technique, and CD7-negative T cells are transduced with a humanized anti-CD7-41BB-CD3ζ lentiviral vector.
This is an investigational study. The objectives are to evaluate the safety and efficacy of CAR7-T cells in patients with CD7+ T-cell malignancies.

CD7 were positive in bone marrow or cerebrospinal fluid by immunohistochemistry or flow cytometry at screening, and one of the following conditions is satisfied:
A. No remission was achieved after at least 2 lines of standard therapy; B. Relapse or progression after standard treatment; C. Relapse after or allogeneic hematopoietic stem cell transplantation;
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Patients will received lymphodepletion with fludarabine (30 mg/kg) and cyclophosphamide (250 mg/kg) on day -5, -4, and -3, followed by the infusion of CAR7-T cells with the dose of 1×10\^6/kg and 2×10\^6/kg (with an allowance of ±20%). If no dose-limited toxicity (DLT) emerges in the group, then the subsequent higher dose will be used in the next group. If DLT emerges in a single subject in any dose level, 3 more subjects will be enrolled to the same dose level. The maximum dose could be extended.
