Chimeric antigen receptor (CAR)-modified T cells targeted against CD19 have demonstrated unprecedented successes in treating patients with hematopoietic and lymphoid malignancies. Besides CD19, many other molecules such as CD22, CD30,BCMA,CD123, etc. may be the potential to develop the corresponding CAR-T cells to treat patients whose tumors express those markers. In this study, investigators will evaluate the safety and efficacy of Sequential CAR-T Cells Targeting CD5/CD7 in patients with patients with relapsed or refractory T-ALL/LBL/ETP-ALL. The primary goal is safety assessment including cytokine storm response and any other adverse effects. In addition, disease status after treatment will also be evaluated.
Acute lymphoblast leukemia (T-ALL) is a neoplastic lymphoid leukemia characterized by the proliferation of immature precursor T cells. The combined chemotherapy has significantly improved the prognosis of T-acute lymphoblast leukemia/lymphoma. However, once the disease appears to be relapsed/refractory, there are limited treatment options, and the overall prognosis is extremely poor. Therefore, exploring safe and effective treatments is a critical unmet medical need. The patients will receive Sequential CAR-T Cells Targeting CD5/CD7 to examine the safety and, possibly the efficacy of CD5 CAR T-Cells in CD5+ CD7+ relapsed or refractory acute leukemia.

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.
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 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.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
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.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Patients will be administered fludarabine phosphate intravenously (IV) over a 30-minute period on days -4 to -2. Additionally, cyclophosphamide will be administered intravenously (IV) over 60 minutes on day -2. Subsequently, patients will receive CD5/CD7 CAR T cells intravenously (IV) over a duration of 10-20 minutes on day 0. Patients who exhibit positive responses to the initial dose of CD5/CD7 CAR T cells, do not experience unacceptable side effects, and have a sufficient quantity of cells available may be eligible to receive 2 or 3 additional doses of CD5/CD7 CAR T cells.
Biological: CD5/CD7 CAR-T
The intervention in this clinical trial involves a novel approach using CD5/CD7 Chimeric Antigen Receptor T (CAR T) cells combined with chemotherapy. The goal is to assess safety and efficacy in patients with specific hematologic malignancies. Treatment Regimen: Patients in the trial will undergo the following regimen: Fludarabine Phosphate (Days -4 to -2): IV administration of fludarabine phosphate over 30 minutes on days -4 to -2. It's part of the preparatory regimen to enhance the body's response to CAR T-cell therapy. Cyclophosphamide (Day -2): IV cyclophosphamide over 60 minutes on day -2. CD5/CD7 Chimeric Antigen Receptor T Cells (Day 0): IV administration of investigational therapy, CD5/CD7 CAR T cells, over 10-20 minutes on day 0. Additional Doses: Eligible patients responding well to the initial CD5/CD7 CAR-T cell infusion without unacceptable side effects and sufficient CAR-T cell availability may receive 2 or 3 additional doses.
