This is a single-center, single-arm, open-label phase 1/2 study of CART19 in children and young adults with refractory Systemic lupus erythematosus (SLE), including both patients diagnosed with lupus nephritis (LN) and patients with non-renal Systemic lupus erythematosus (SLE).
Phase 1 will evaluate the safety of CART19 in 6-12 patients with Systemic lupus erythematosus (SLE). There is no planned dose escalation, but a dose de-escalation will be made based on the incidence of Dose Limiting Toxicities. Phase 2 will evaluate the efficacy and further evaluate the safety of CART19 in this population.
Lupus disease activity is associated with increased numbers of activated naïve B cells and polyclonal expansion of antibody secreting cells, indicating a central role for B cells in the pathogenesis of SLE. While traditional anti-CD19 antibody therapies have been utilized with varying success in the treatment of Systemic lupus erythematosus (SLE), CD19 directed cellular therapies have emerged as an attractive therapeutic option that may lead to immunosuppression-free remission in this population given the ability of CD19 directed CAR T cells to more deeply deplete the B cell compartment. Previous clinical experience utilizing CD19 directed CAR T cells in patients diagnosed with Systemic lupus erythematosus (SLE) have exceeded any other Systemic lupus erythematosus (SLE) therapeutic available; although, those clinical trials have treated a limited number of subjects. During this trial the test article will be CART19 cells transduced with a lentiviral vector to express anti-CD19 scFv:41-BB:TCRζ, administered by IV injection.

Compared within Lupus Nephritis, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Lupus Erythematosus, Systemic. The counts are of registry records indexed under each term, refreshed daily. How we classify →
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.
Active () disease, defined as follows:
a. Lupus nephritis subjects must meet both the following criteria: i. ISN/RPS active nephritis Class III/IV +/- V lupus nephritis diagnosed by within past 12 months.
ii. Persistent and : ≥2 measurements with urine protein with either of the following:
6. Patients must have had at least 3 months of cumulative conventional therapy defined as:
i. B-cell directed biologic therapy (e.g., rituximab, belimumab, ofatumumab, obinutuzumab) ii. Calcineurin inhibitor (e.g., tacrolimus, cyclosporine, voclosporin) iii. Other immunosuppressive medication for SLE (e.g., anifrolumab, abatacept, JAK inhibitor) 7. Adequate organ function status
Pulmonary: Must have a minimum level of pulmonary reserve defined as ≤ Grade 1 dyspnea and \<Grade 3 hypoxia; DLCO ≥40% (corrected for anemia and/or VA volume if necessary) if PFTs are clinically appropriate as determined by the treating investigator.
8. Subjects of must agree to use acceptable methods.
Exclusion Criteria:
Active
a. Patients must have a negative hepatitis B surface antigen to be enrolled on this study.
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.
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.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
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.
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.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
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.
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.
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.
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.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
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.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
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.
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 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 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.
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.
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.
