Engineered immune cells target CD5 in Hard-to-Treat T-Cell lymphomas
NCT ID NCT07022964
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing a new immune cell therapy called CD5 CAR-T in people with mature T-cell lymphomas that have come back or stopped responding to standard treatment. The trial enrolls about 36 participants, ages 14 to 70, who have few remaining options. Participants receive an infusion of engineered immune cells designed to recognize and attack lymphoma cells that carry the CD5 protein. The main goal is to measure safety and dose-limiting side effects within the first three weeks, and to see how many participants respond to the treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CD5 CAR-T cells, a type of immune cell therapy engineered to target the CD5 protein on lymphoma cells
- What this could lead to
- If it works, this approach could offer a new treatment option for people with T-cell lymphomas that have stopped responding to standard therapy, and could help them reach a stem cell transplant.
- What could go wrong
- This is an early-phase trial with a small number of participants, so safety and effectiveness are still unknown. CAR-T therapies can cause serious side effects, and the treatment may not work for everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria (Patients who met all the inclusion criteria were eligible for enrolment): * Relapsed or refractory CD7-positive T-cell lymphomas that were treated with with standard chemotherapy, with poor prognosis from currently available treatments at and no available treatment options (e.g., HSCT or chemotherapy); * Male or female, age 14-70; * Eastern Cooperative Oncology Group (ECOG) Physical Status Score 0-2; * life expectancy is at least 60 days; * Subjects should be capable of understanding and signing the informed consent form prior to any screening procedures. Subjects are willing to follow the study visit schedule and associated study procedures as specified in the protocol. Candidates between the ages of 19-70 years old will need to be sufficiently aware of and capable of signing the informed consent form; underage candidates between the ages of 14-18 years old will need to be sufficiently aware of the informed consent form and their legal guardian will also need to sign the informed consent form separately. Exclusion Criteria (Patients who fulfil any of the following criteria may not be enrolled): * Patients with history of allogeneic HSCT but PBMNC is not available from prior- transplant donor for preparation of CAR T cells and peripheral blood tumour load \>30%; patients without history of allogeneic HSCT and peripheral blood tumour load \>30%; * Intracranial hypertension or cerebral impaired consciousness; * Symptomatic heart failure or severe arrhythmia; * Symptoms of severe respiratory failure; * With other types of malignancy; * Diffuse intravascular coagulation; * Serum creatinine and/or urea nitrogen ≥ 1.5 times the normal value; * With sepsis or other uncontrollable infection; * Suffering from uncontrollable diabetes mellitus; * Severe mental disorders; * Have significant intracranial lesions on cranial MRI; * Organ transplantation (excluding haematopoietic stem cell transplantation) history; * Female patients (patients of childbearing potential) with positive blood HCG test; * Hepatitis (including hepatitis B and C) and positive screening for AIDS and syphilis.
