Brain scans and blood tests to spot neurotoxicity after CAR T-cell therapy

Comprehensive Neuroimaging and Molecular Biomarkers of Neurotoxicity Following CAR T-Cell Therapy

Observational University of California, San Diego · NCT07075523

This project will try brain MRIs, cognitive tests, and blood biomarkers to see if we can identify which adults receiving CAR T-cell therapy will develop neurotoxicity (ICANS).

What this trial studies

This prospective, open-label, single-arm study enrolls adults scheduled for commercial CAR T-cell therapy and performs advanced brain MRI, neurocognitive testing, quality-of-life questionnaires, and blood biomarker measurements. Three MRI modalities (T1-post-contrast, T2/FLAIR, diffusion-weighted) plus resting-state functional MRI are used to capture structural and functional changes. Neurocognitive testing and questionnaires (including measures like RBANS) and blood — and optionally CSF — biomarker sampling are collected in the acute phase (2–14 days after infusion) and again at about 3 months. Data will be combined to develop a novel tool aimed at early identification of immune effector cell-associated neurotoxicity syndrome (ICANS).

Who should consider this trial

Good fit: Adults aged 18 or older who are scheduled to receive commercial CAR T-cell therapy and can comply with MRI and follow-up visits are ideal candidates.

Not a fit: Patients who are not receiving CAR T-cell therapy or who have contraindications to MRI (or severe pre-existing neurologic conditions that confound assessment) are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the tool could identify patients at risk for ICANS earlier, allowing clinicians to intervene sooner and potentially reduce neurological complications.

How similar studies have performed: Smaller imaging and biomarker studies have shown promising signals for detecting ICANS, but a validated early predictive tool has not yet been established.
