Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are pediatric patients aged 30 years or younger who have received their first CAR T cell infusion within the last 1-3 months.
✕Probably not a fit
Patients with active malignancies other than the one being treated or those planning additional therapies may not benefit from this study.

What this trial studies
This observational study aims to assess the short-term and long-term side effects of CAR T cell therapy in pediatric patients. Researchers will monitor the incidence and severity of bone marrow dysfunction, infections, and neurotoxicity at various intervals following treatment. Data will be collected at 3 months, 6 months, 1 year, and 2 years post-infusion, allowing for a comprehensive understanding of the therapy's delayed effects. The study focuses on patients with B-ALL, hematologic malignancies, and solid tumors.
Why it matters
Potential benefit: If successful, this study could provide critical insights into the safety and long-term effects of CAR T cell therapy, improving patient management and outcomes.
How similar studies have gone: While there have been studies on CAR T cell therapy, this specific focus on delayed effects in pediatric populations is relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Participants must have received an initial systemically-administered CAR T cell infusion for an oncologic diagnosis within the last 1-3 months (+/- 14 days). * Initial infusion is defined as the first administration of a CAR T cell product the participant has not previously received OR receipt of a CAR T cell product previously received after an interval allogeneic HSCT. * Age ≤ 30 years at CAR T cell infusion. Exclusion Criteria: * Active malignancy other than the disease under study. * Planned consolidative HSCT within 3 months post CAR T cell infusion. * Received or planned additional disease directed therapy post CAR T cell infusion. * Inability or unwillingness of research participant or legal guardian/representative to give written informed consent.
