Study summary

This pilot study examines the safety and efficacy of anti-CD19 CAR T cells manufactured on-site in children and young adults with relapsed or refractory CD19+ B cell acute lymphoblastic leukemia or CD19+ B cell non Hodgkin lymphoma.

Patients will undergo screening, leukapheresis (cell collection), lymphodepleting chemotherapy with fludarabine and cyclophosphamide, followed by the anti-CD19 CAR T cell infusion. The lymphodepleting chemotherapy is administered over four days IV to prepare the body for the CAR T cells. The anti-CD19 CAR-T cells are infused between 2-14 days after the last dose of chemotherapy. This study is designed for participants to begin lymphodepleting chemotherapy during the CAR T cell manufacture and receive a fresh cell infusion on the day that manufacturing is complete. Some patients may need more time in between the cell collection and the CAR T cell infusion, therefore, the cells may be manufactured and frozen prior to administration. Patients will be followed for a year after the cell infusion on the study and for up to 15 years to monitor for potential long term side effects of cell therapy.

Read the detailed description

PRIMARY OBJECTIVE:

  • To examine the feasibility of manufacture and administration of autologous CD19 CAR T cells at a minimum target dose of 0.3 x 10\^6 to 1 x 10\^6 per kilogram for patients \<50 kg and a flat dose of 0.3 - 1 x 10\^8 for patients ≥50 kg using the Miltenyi CliniMACS Prodigy automated T Cell Transduction (TCT) process.
  • To evaluate the safety of administration of CD19 CAR T cells after lymphodepletion with fludarabine and cyclophosphamide.

SECONDARY OBJECTIVE:

  • To estimate the efficacy of CD19 specific CAR-T cells in pediatric and young adult patients with relapsed/refractory CD19+ B-cell ALL and NHL.

EXPLORATORY OBJECTIVE:

  • To evaluate the persistence of CD19 CAR T cells after infusion.

The autologous lymphocytes are collected from the patient via apheresis. The apheresis product is then transported to the on-site GMP facility for manufacture of the CAR T cell product. Patients may be admitted to begin lymphodepleting chemotherapy during the CAR T cell manufacturing process. When the CAR T cell product is ready, the cells may be administered fresh or may be cryopreserved for use at a later date depending on the patient's clinical status.

All patients will be admitted to the hospital to undergo a Fludarabine/Cyclophosphamide based leukoreduction conditioning regimen to be completed 2-14 days prior to CAR T cell infusion. Patients will be admitted for a minimum of 7 days after the CAR T infusion to monitor for toxicity including cytokine release syndrome, neurologic toxicity, and tumor lysis syndrome.

Lymphodepleting chemotherapy:

  • Fludarabine 30 mg/m2/day IV x 4 days
  • Cyclophosphamide 500 mg/m2/day IV x 2 days

CD19 CAR T cell dose:

  • 0.3 x 10\^6 to 1 x 10\^6 per kilogram for patients \<50 kg
  • Flat dose of 0.3 - 1 x 10\^8 for patients ≥50 kg

Terms in these criteria, in plain language(19)

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.

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.

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.

Line of therapy

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.

Biopsy and archival tissue

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.

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.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

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.

ULN (upper limit of normal)

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.

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.

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.

Childbearing potential

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.

Contraception

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.

GVHD (graft-versus-host disease)

After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.

Investigational drug or device

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.

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.

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.

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 Aug 15, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
