Prospective Evaluation Of Delayed Effects Of Pediatric Car T Cell Therapy
What this study is about
This study is being done to learn more about the short-term and long-term side effects of CAR-T cell therapy. Specifically, researchers want to know how often patients get infections, have delays in recovering blood cell counts and/or have damage to the nervous system.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
