Study summary

The purpose of this clinical trial is to assess the feasibility, safety and efficacy of multiple 4SCAR-T cell therapy which targets GD2, PSMA and CD276 surface antigens in patients with relapsed and refractory neuroblastoma (NB). Another goal of the study is to understand the function of the multi-CAR-T cells and their persistency in the patients.

Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.

Neuroblastoma is one of the most aggressive childhood tumors arising from neural crest cells. Nearly 50% of patients with high risk disease have poor long-term survival even after multimodal treatments. Novel immunotherapy targeting tumor-specific antigens has been developed to meet the desperate need.

Disialoganglioside (GD2) is a well-studied tumor associated antigen which is expressed uniformly in NB but restrictedly in normal tissue. Over the past few years, CAR-T therapy against GD2 in NB has achieved encouraging but modest outcomes. Only a fraction of patients achieved measurable responses. Like for many other solid tumors, CAR-T therapy for NB is not as effective as for hematologic malignancies.

In this study, the investigators use "multiple targeting" approach as the strategy to overcome the challenge in treating NB. Prostate-specific membrane antigen (PSMA) is expressed in normal prostate but is upregulated in prostate tumor. However, PSMA expression is not restricted to prostate cancer. By immunohistochemistry (IHC) staining, the investigators confirmed that PSMA is expressed in a variety of solid tumors, including brain tumor, neuroblastoma and some lymphoma tumor tissues. Therefore, PSMA could potentially serve as a promising target for antigen-specific immunotherapy in patients with NB. In addition, CD276 (B7-H3) is an immune checkpoint molecule highly expressed on many solid tumors including NB. CD276 has been characterized to be involved in tumor evasion and thus its expression is correlated with poor prognosis. These characteristics make CD276 an attractive candidate for immunotherapy. Given the significant variation of tumor antigen expression among patients, the investigators aim to examine GD2, PSMA and CD276 expression in each patient's tumor sections by IHC staining, and combine two or three highly-expressed targets for the 4SCAR-T therapy. This individualized and multi-antigen-targeted approach is a new strategy to overcome the limited clinical outcome in the 4SCAR-T therapy against NB.

The purpose of this clinical study is to assess the feasibility, safety and efficacy of the combinational GD2, PSMA and CD276 4SCAR-T cell therapy against NB. Another goal of the study is to learn more about the function of the multi-4SCAR-T cells and their persistency in the patients.

Terms in these criteria, in plain language(16)

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.

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

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.

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.

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.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

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.

Immunosuppression

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.
