This is a phase l multi-centric, single arm, prospective open, dose-escalation study in patients with relapsed or refractory CD19-positive B cell malignancies (ALL, NHL, CLL). The trial will include adult and pediatric patients. In total approximately 48 patients will be included in the trial. There will be three individual cohorts, defined by disease biology: pediatric ALL and aggressive pediatric NHL (Cohort 1), adult ALL (Cohort 2) and adult NHL/CLL (Cohort 3).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Male or female patients must have r/r CD19-expressing ALL or NHL/CLL
* CD19 expression must be detected on the malignant cells by flow cytometry (leukemia, malignant effusion in NHL) or immunohistochemistry (NHL);
* Age ≥ 1 year (if deemed fit by treating investigator);
* Absolute CD3+ T cell count ≥100/μl;
* ECOG performance score of 0-2 if \>16 years old, or Lansky performance score of \>50 if ≤16 years old at screening;
* No active Hepatitis B, Hepatitis C, HIV1/2;
* No childbearing potential or negative pregnancy test at screening and before chemotherapy in women with childbearing potential;
* Signed and dated informed consent/assent by patients
* and meet the following disease-specific criteria:
ALL:
* patients with \>5% blasts in BM (M2 or M3) after at least one standard chemotherapy and one salvage regimen who are ineligible for allogeneic stem cell transplant (alloSCT) or have refractory disease activity precluding alloSCT at this time, or
* patients who have relapsed post alloSCT at least 100 days posttransplant, with no evidence of active GVHD, and no longer taking immunosuppressive agents for at least 30 days prior to enrollment.
* patients with Ph+ ALL if they are intolerant to tyrosine kinase inhibitor (TKI) therapy, or if they have r/r disease after treatment with at least 2 different TKIs.
* ALL patients with combined bone marrow and CNS and/or testicular relapse are eligible only if the extramedullary disease has been successfully clea…
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?
