Abstract

CD19-specific chimeric antigen receptor (CAR) T-cell therapy is highly effective against relapsed or refractory acute lymphoblastic leukemia (ALL), but is hindered by neurotoxicity. In 53 adult patients with ALL, we found a significant association of severe neurotoxicity with high pretreatment disease burden, higher peak CAR T-cell expansion, and early and higher elevations of proinflammatory cytokines in blood. Patients with severe neurotoxicity had evidence of blood–cerebrospinal fluid (CSF) barrier disruption correlating with neurotoxicity grade without association with CSF white blood cell count or CAR T-cell quantity in CSF. Proinflammatory cytokines were enriched in CSF during severe neurotoxicity with disproportionately high levels of IL6, IL8, MCP1, and IP10, suggesting central nervous system–specific production. Seizures, seizure-like activity, myoclonus, and neuroimaging characteristics suggested excitatory neurotoxicity, and we found elevated levels of endogenous excitatory agonists in CSF during neurotoxicity. Significance: We detail the neurologic symptoms and blood, CSF, and neuroimaging correlates of neurotoxicity associated with CD19 CAR T cells and identify neurotoxicity risk factors. Our findings implicate cellular components other than T cells and suggest novel links between systemic inflammation and characteristic neurotoxicity symptoms. Cancer Discov; 8(8); 958–71. ©2018 AACR.

  • Clinical-pathologic correlation in these individuals resulted in valuable observations that may be instructive in understanding mechanisms of immune-induced pathologies, including those of checkpoint inhibitors, CAR-T cells, and infections such as COVID-19.

    “Clinical–pathologic correlation in these individuals resulted in valuable observations that may be instructive in understanding mechanisms of immune-induced pathologies, including those of checkpoint inhibitors, CAR-T cells, and infections such as COVID-19, known to target mucosal tissues and cause severe CRS [1, 5, 8, 18, 19].”

  • Cytokine release syndrome and neurotoxicity are the most serious immune-related adverse events, and they are most prominently reported in patients given CAR-T cells.

    “The most severe of these immune-related adverse events (irAEs) are cytokine release syndrome (CRS) and neurotoxicity, most prominently described in patients treated with CAR-T-cells [6–11].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
