Study summary

The prognosis of patients with relapsed and/or refractory T-cell hematologic malignancies is poor due to lacking sufficient treatment.Anti-CD(cluster of differentiation antigen)19 CAR(chimeric antigen receptor)-T cell therapies are efficient for patients with B-cell hematologic malignancies. As for T-cell hematologic malignancies, CD7 is a promising target expressed on most malignant T cells. The outcome of CD-7 CAR-T cell therapy pre-clinical experiments is cheerful.however, how to select the functional T cells from the malignant T cells is a challenge. In addition to this, auto-CAR-T cell therapy is not affordable for the majority of patients. Using T cells aphesis from healthy donors edited to avoid rejection of the host as the material of anti-CD7 universal CAR-T cells could be accessible and affordable, which is adapted for patients with CD7+ relapsed and/or refractory T/NK-cell hematologic malignancies.

Inclusion criteria

    1. Diagnosis of recurrent T-cell acute lymphoblastic leukemia (T-ALL), T-cell acute lymphoblastic lymphoma (T-LLy), or T-non-Hodgkin lymphoma (T-NHL, including Angioimmunoblastic T-cell lymphoma (AITL), Enteropathy-associated T-cell lymphoma (EATL), Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), Peripheral T-cell lymphoma (PTCL) NOS, Anaplastic large cell lymphoma (ALCL), Adult T-cell leukemia/lymphoma, T cell prolymphocytic leukemia with symptomatic disease, Extranodal NK/T cell lymphoma, Mycosis fungoides/ Sezary Syndrome Stage IIB or higher))

      1. CD7-positive tumor (≥20% CD7 positive blasts by flow cytometry or immunohistochemistry (tissue))
      1. ≥ 7.0 (can be transfused)
      1. greater than 12 weeks
      1. explained to, understood by and signed by the patient/guardian. Patient/guardian is given a copy of informed consent.

Exclusion criteria

Exclusion Criteria:

  1. Pregnant or lactating.
  2. Tumor in a location where enlargement could cause airway obstruction (per investigator discretion).
  3. Active infection with or HTLV.
  4. viral infection or uncontrolled viral reactivation of EBV(Epstein-Barr virus), CMV(cytomegalovirus), ADV(adenovirus), BK-virus, or HHV(human herpesvirus)-6.
  5. Any of the following cardiac criteria: Atrial fibrillation/flutter; Myocardial infarction within the last 12 months; Prolonged syndrome or secondary prolonged QT, per investigator discretion. Cardiac echocardiography with LVSF (left ventricular shortening fraction)\<30% or (left ventricular ejection fraction)\<50%; or clinically significant pericardial effusion. Cardiac dysfunction (New York Heart Association) III or IV (Confirmation of absence of these conditions on echocardiogram within 12 months of treatment).
  6. CNS abnormalities: Presence of CNS(central nervous system)-3 disease defined as detectable cerebrospinal blast cells in a sample of CSF(cerebrospinal fluid) with ≥ 5 WBC( white blood cell)s per mm3 (unless negative by the Steinherz/Bleyer algorithm); Presence of any CNS disorder such as an uncontrolled seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any disease with CNS involvement.
Terms in these criteria, in plain language(9)

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.

Hemoglobin (Hb)

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).

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Informed consent

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.

HIV

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.

Clinically significant

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.

QT and QTc

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.

LVEF (left ventricular ejection fraction)

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

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.

Autoimmune disease

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.
