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.

Who should consider this trial

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.

Not a fit: Patients with active malignancies other than the one being treated or those planning additional therapies may not benefit from this study.

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 performed: While there have been studies on CAR T cell therapy, this specific focus on delayed effects in pediatric populations is relatively novel.

Eligibility criteria

Inclusion Criteria:

* Participants must have received an initial systemically-administered CAR T cell infusion 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.
