Study summary

This is a phase 1 clinical trial of autologous CD7-CAR T cells in the treatment of high-risk acute T-cell leukemia / lymphoma. Twenty subjects will be enrolled. Subjects will be pretreated with chemotherapy prior to infusion of CAR T cells: about 3 days before cells transfusion, the patients who planned to reinfuse CAR T cells were treated with fluorodarabine 30 mg/m2( body surface area) and cyclophosphamide 250 mg/m2( body surface area) for 3 days. Then this study will be using a 3+3 dose escalation approach from dose 1 (DL-1): 5×105 (±20%) to dose 2 (dl-2): 1×106 (±20%). Below the lowest dose was reinfused at the PI's discretion.

Inclusion criteria

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

  1. Diagnosed as a high-risk acute T-cell leukemia / lymphoma patient with complete remission within 3 months and persistent positive of minimal residual disease, expressing tumor surface antigen CD7
  2. or relapsed T-cell acute lymphoblastic leukemia/lymphoma patients with no blasts in peripheral blood by flow cytometry and suspending anti-neoplastic treatment for more than 2 weeks

  6. Have of at least 60 days based on investigator's judgement
  7. CD7 positive in bone marrow or peripheral blood or immunohistochemistry
  8. Candidates aged 8-70 years need to be sufficiently conscious and able to sign the treatment consent form and voluntary consent form. And Pediatric patients under 8 years old could be recruited after signing an form by a legal surrogate (Guardian)
  9. Minimal residual disease was positive after chemotherapy and there were of hematopoietic stem cell transplantation.

Exclusion criteria

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

  1. Intracranial hypertension or disorder of consciousness
  2. Symptomatic heart failure or severe arrhythmia
  3. Symptoms of severe respiratory failure
  4. Complicated with other types of malignant tumors
  5. Diffuse intravascular coagulation
  6. Serum creatinine and / or blood urea nitrogen ≥ 1.5 times of the normal value
  7. Suffering from septicemia or other uncontrollable infections
  8. Patients with uncontrollable diabetes
  9. Severe mental disorders
  10. Obvious and active intracranial lesions were detected by cranial magnetic resonance imaging (MRI)
  11. Have received organ transplantation (excluding hematopoietic stem cell transplantation);
  12. Reproductive-aged female patients with positive blood HCG test
  13. Screened to be positive of infection of hepatitis (including and C), AIDS or syphilis
Terms in these criteria, in plain language(7)

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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

ECOG performance status

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.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

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.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Hepatitis B tests

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2021 to primary completion in Sep 2023, 23 months.

Of 40 non-industry phase 1 interventional studies under Lymphoma, T-Cell, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 26 and three quarters within 75. This study's 23 months is below that.

Counting every sponsor, half of 59 studies reached it within 57 months; a quarter within 26 and three quarters within 99.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 14, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
