From the registry’s dates

  • Primary completion was expected by Dec 2024, 1 year 10 months ago, but the record still lists the study as recruiting.
  • Registered 10 months after the study started (first participant enrolled Sep 2017, registered Jul 2018).
  • Started Sep 2017; still recruiting 9 years 2 months later.

Study summary

This is a single center, open-label ,phase 1/2 study to evaluate the safety and efficacy of targeted CD19/CD22 chimeric antigen receptor engineered T cell immunotherapy (CART) in the treatment of CD19/CD22 positive Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.

Read the detailed description

The patients will receive infusion of CART cells targeting CD19 and CD22 to confirm the safety and efficacy of CD19/CD22 CART Cells in Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.

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.

Inclusion criteria

  • Male or female patients with CD19+/CD22+ B-cell acute lymphoblastic leukemia who have a dismal prognosis (estimated survival from several months to \<2 year). The study will enroll 20 evaluable patients as follows:
  • Age 6-65 years.
  • ≥ 0.5 by echocardiography.
  • Creatinine \< 1.6 mg/dL.
  • /aspartate aminotransferase \< 3x .
  • \<2.0 mg/dL.
  • performance status ≥ 60
  • Expected survival time ≥ 3 months (according to investigator's judgement)

Exclusion criteria

Exclusion Criteria:

  • Pregnant or lactating women.
  • Uncontrolled active infection.
  • Active or infection.
  • Class III/IV cardiovascular disability according to the Classification.
  • infection.
  • Patients with history of seizure
  • Active central nervous system leukemia
Terms in these criteria, in plain language(10)

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.

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.

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.

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.

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.

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.

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.

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.
