Background:
Chemokine receptor 4 (CCR4) is a protein that is found on the surface of certain T-cell lymphoma cells and is common in mature T-cell cancers. White blood cells can be changed with molecules called anti-CCR4 to express a chimeric antigen receptors (CAR), which is a molecule that directs a white blood cell to attack other cells. The CAR in this study attacks the CCR4 protein found on your T-cell lymphoma. This type if therapy is called gene therapy. Gene therapy involves a person s own white blood cells modified to target cancer cells. More research is needed to find out if gene therapy can treat T-cell cancers and do it safely.
Objective:
To test safety of giving people with certain mature T-cell lymphomas their own white blood cells modified with anti-CCR-4 CAR.
Eligibility:
People aged 18 and older with certain mature T-cell lymphomas that have not responded to or have come back after treatment. They must have a T-cell lymphoma that has CCR4 on the surface of the cancer cells.
Design:
Participants will be screened. They will have a medical history and physical exam. Tests of blood, urine, and heart and lung function will be done.
Participants will have tests:
Computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging scans: They will lie on a table that slides into a donut-shaped machine or a tube. Pictures of the inside of the body will be taken. Before the PET scan, they will get an injection of radioactive fluid in a vein in the arm. Before the MRI, they may get a contrast dye injected through a vein (IV) in the arm.
A biopsy of the tumor may be taken. A bone marrow sample may be taken from the hip: The area will be numbed and a large needle inserted through the skin.
Leukapheresis will be done to obtain T-cells that will be genetically modified to express anti-CCR4 CARs on T-cells: Blood is drawn through an IV in one arm, circulated through a machine, and then returned through an IV in the other arm.
Chemotherapy drugs will be given in an IV to prepare the body to accept the modified CAR T cells.
The modified cells will be given in an IV.
Participants will be followed for 15 years: This will require blood tests over the first 1-2 years followed by yearly visits and possibly telehealth updates.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Pathologically () confirmed histologic diagnosis of a CCR4+ mature T-cell from one of the following subtypes: peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL), anaplastic large cell lymphoma (ALCL), hepatosplenic t-cell lymphoma (HSTCL), monomorphic epithelialtropic intestinal lymphoma (MEITL), enteropathy associated T-cell lymphoma (EATL) or cutaneous T-cell lymphoma (CTCL) including mycosis fungoides and subacute panniculitis-like T-cell Lymphoma, or lymphomatous subtypes of ATL without evidence of CNS involvement or substantial circulating disease confirmed by the Laboratory of Pathology, NCI.
--CCR4+ is defined as >= 10% malignant cells positive for CCR4 by immunohistochemistry. It is preferred to have a fresh biopsy to confirm the CCR4 status. In the event a fresh biopsy cannot be safely performed in the opinion of the treating physician, an archival biopsy sample taken at the time of previous progression can be used.
NOTE: Tissue will be used for assessment of CCR4 expression on malignant cells by immunohistochemistry with any leftover slides or samples to be used for correlative studies. Tumor tissue may be from any previously collected tissue and adequacy is at the discretion of the Principal Investigator. If prior tissue is not available, a screening biopsy will be necessary unless repeat biopsy is deemed unsafe by the treating physician in consultation with the Principal Investigator.
Participants must have disease that is relapsed or refractory after prior therapy as follows:
Adequate organ function as evidenced by the following laboratory parameters:
Note: Participants with well-controlled atrial fibrillation are eligible.
-- and DLCO > 60% of predicted (adjustment for Hgb acceptable)
-Individuals of (IOCBP) must have a negative urine or blood HCG pregnancy test at screening.
NOTE: IOCBP is defined as any person assigned female at birth who has experienced menarche and who has not undergone successful surgical sterilization or who is not .
-Individuals of child-bearing potential (IOCBP) must agree to use highly effective (hormonal, intrauterine device [IUD], abstinence, surgical sterilization) or practice abstinence starting at the time of study entry, for the duration of study therapy, and 12 months after the last dose of combined chemotherapy.
Individuals able to father a child must agree to use an effective method of contraception (barrier, surgical sterilization, abstinence) for the duration of the study treatment and for 4 months after the last dose of combined chemotherapy. We also will recommend these individuals with partners of childbearing potential ask partners to be on highly effective birth control (hormonal, IUD, surgical sterilization)
EXCLUSION CRITERIA:
Participants with prior autoimmune thyroiditis who are now on stable thyroid replacement therapy are also eligible.
Current or prior anti-cancer treatment prior to the first dose of study drug as defined below:
NOTE: Participants seropositive for hepatitis C virus (HCV) infection must have been treated and cured as defined by undetectable HCV viral load.
-Active infection.
NOTE: Participants that are positive for hepatitis B core antibody (HBcAb) or hepatitis B surface antigen (HBsAg) must have a negative hepatitis B virus polymerase chain reaction (HBV PCR) result \<100 IU/mL at screening. Those who are HBV PCR positive are excluded. Those hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) positive with a negative PCR for hepatitis B will be treated with antivirals designed to prevent hepatitis B reactivation (e.g., entecavir) and have monitoring for hepatitis B reactivation with PCR.
NOTE: History of radiation pneumonitis in the radiation field (fibrosis) is allowed.
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 biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
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.
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.
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.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
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.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
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.
From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
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.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
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.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
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.
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.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
