Multi-modular Chimeric Antigen Receptor Targeting GD2 in Neuroblastoma
United Kingdom12 participantsStarted 2024-04-19
Plain-language summary
MAGNETO is a single-centre, non-randomised, open label Phase I clinical trial of an Advanced Therapy Investigational Medicinal Product (ATIMP) in children and teenagers aged 1-16 years with relapsed or refractory neuroblastoma.
The study will assess the feasibility of generating the ATIMP (GD2 CAR T cells) and the safety of administering the ATIMP in patients with relapsed or refractory neuroblastoma.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Age ≥ 1 and ≤ 16 years.
. Tissue diagnosis of neuroblastoma. If sufficient biopsy material is available, GD2 expression on the tumour will be confirmed. As GD2 is consistently expressed in neuroblastoma demonstration of GD2 is not mandated.
. Disease which has relapsed after or is refractory to at least one line of salvage combination chemotherapy.
. Measurable disease by cross sectional imaging or evaluable disease by uptake on 123I-MIBG scan. Patients with only bone marrow detectable disease (bone marrow aspirate or trephine) are NOT eligible for the study.
. At least 3 weeks or 5 half-lives, whichever is shorter, after treatment with agents on other early phase clinical trial.
. Performance status: Karnofsky (age ≥ 10 years) or Lansky (age \< 10) score ≥ 50%. Patients who are unable to walk because of paralysis, but who are able to sit upright unassisted in a wheelchair, will be considered ambulatory for the purpose of assessing performance score.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Safety of administering the ATIMP
Timeframe: 28 days
2
Number of therapeutic products generated and the number of ATIMPs infused after successful manufacture
. Creatinine ≤1.5 ULN for age, if higher, an estimated (calculated) creatinine clearance must be ≥ 60 ml/min/1.73 m2.
. Absolute lymphocyte count ≥ 0.25 x 10\^9/L.
Exclusion criteria
. Patients with only bone marrow detectable disease in the absence of measurable disease by cross sectional imaging or evaluable disease by uptake on 123I-MIBG scan.
. Patients with active, inoperative CNS disease including leptomeningeal disease.
. Active hepatitis B, C or HIV infection.
. Inability to tolerate leukapheresis.
. Clinically significant systemic illness or medical condition (e.g., significant cardiac, pulmonary, hepatic or other organ dysfunction), that in the judgement of the investigator is likely to interfere with assessment of safety or efficacy of the investigational regimen and its requirements.
. Any contraindication to lymphodepletion or to the use of Cyclophosphamide or Fludarabine as per the local SmPC.
. Any contraindication to the use of Anticoagulant Citrate Dextrose Solution.
