Is this trial a fit for you?

Likely a good fit

Ideal candidates include children and young adults aged 5-35 with relapsed or refractory leukemia or lymphoma who are scheduled to receive CAR T-cell therapy.

Probably not a fit

Patients who do not have blood cancer or are outside the age range of 5-35 years may not benefit from this study.

What this trial studies

This observational study aims to evaluate the cognitive aftereffects of CAR T-cell therapy in children and young adults aged 5-35 with relapsed or refractory leukemia or lymphoma. Researchers will assess how this innovative treatment may impact memory, attention, and other cognitive functions over a 12-month period. Participants will undergo cognitive testing either at home or at designated clinical sites, and their medical histories will be reviewed to gather comprehensive data. The study also involves caregivers who will provide additional insights into the participants' cognitive performance.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the cognitive effects of CAR T-cell therapy, potentially leading to improved management strategies for patients undergoing this treatment.

How similar studies have gone: While CAR T-cell therapy has shown promise in treating blood cancers, the specific focus on cognitive outcomes in this context is relatively novel and has not been extensively studied.
