Study summary

This study aims to evaluate the safety and clinical activity of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in treating patients with recurrent or refractory CD19 positive B cell ccute lymphoblastic leukemia,and dynamically observe the changes of CAR-T in patients and the residual tumor.

Read the detailed description

In this single-center, open-label, single-arm, prospective clinical trial, a total of 20 recurrent or refractory CD19+ B cell acute lymphoblastic leukemia patients will be enrolled.After recruiting eligible patients,autologous peripheral blood mononuclear cells(PBMCs) will be purified from whole blood.The CD3+ T cells were subsequently selected and re-stimulated by anti-CD3 and anti-CD28 monoclonal antibodies.T cells will be transduced with lentiviral vector for the generation of the CD19 CART cell and administered by i.v. injection.The purpose of current study is to determine the safety and clinical efficacy of CD19 CAR T cells therapy in patients with recurrent or refractory CD19+ ALL.

Exclusion criteria

Exclusion Criteria:

.Other concurrent severe and/or uncontrolled medical conditions: patients with another primary malignant disease; another severe and/or life-threatening medical disease.

  • Evidence of uncontrolled current serious active infection
  • // infection
  • Pregnancy and nursing females
  • Systemic therapy within one week
Terms in these criteria, in plain language(14)

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.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

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.

ECG (electrocardiogram)

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.

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.

ALT and AST (liver enzymes)

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.

Bilirubin

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.

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).

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.

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.

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.

Hepatitis C tests

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.

Corticosteroids (steroids)

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.

Study arms

  • Experimental
    B-ALL treated with CD19 CART cell

    The qualified CD19-targeted CART cells will be transferred to patient for 3 days as follow:D1,10% fraction;D2,30%;D3 60%. The number of CART cells for each course will be about 1×106/kg. If complete response (CR) or complete response with incomplete hemogram recovery (CRi) in hemogram is achieved after the first course of treatment, further treatment will be decided according to the clinical assessment and the wishes of the patient.If partial response (PR) is achieved after the first course, 1 or 2 courses of treatment will be continued. If there is no response (NR) after the first course, the treatment will be ceased or restarted based on the clinical assessment or patients' wishes. Treatent may be discontinued due to any severe toxicity, such as cytokine release syndrom.

    Biological: CD19-targeted CART cells

Interventions

  • BiologicalCD19-targeted CART cells

    CD19 CAR T cells was transduced with a lentiviral vector to express anti-CD19 scFv.This is a second generation CRAT.

What researchers measure

Primary outcomes

  1. overall response rate(ORR)

    ORR is defined as the proportion of partial responses plus complete responses.

    Time frame: Participants will be followed for the duration of the treatment, with an expected average of 3 months.

Secondary outcomes

  1. Progression free survival(PFS)

    Progression-free survival is defined as the time from enrollment to first observation of progression or date of death (from any cause).

    Time frame: 15 years

  2. Overall survival(OS)

    Overall survival, defined as the time from enrollment until death due to any cause. For patients who do not die, time to death will be censored at the time of last contact.

    Time frame: 15 years

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 Feb 26, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
