Autoimmune Neurological Diseases and Those Secondary to Immunotherapy: Study of Immunological Mechanisms and Research Into Targets of Immune Attack
Sponsor: Assistance Publique - Hôpitaux de Paris
Summary
The pathophysiology of neurological toxicities secondary to immune checkpoint inhibitors (ICIs) is unknown. Various mechanisms have been proposed: activation of cytotoxic CD8 T cells, autoantibodies via activation of B cells and CD4 cells, non-specific inflammation through the production of pro-inflammatory cytokines, and complement activation. The aim of this research is to characterise the pathophysiological mechanisms of neurotoxicities in cancer patients treated with ICIs.

Lumbar puncture and blood sampling
For all patients in the study, lumbar puncture will be performed as part of their care, according to the clinical indication given by the referring physician. If the patient gives their consent, an additional volume of CSF will be collected for this study, so that the total volume collected (care plus research) does not exceed 5 mL. No lumbar puncture will be performed specifically for the study. Blood samples will also be collected: these are additional blood tubes collected during a blood sample taken as part of the treatment (as described in the section 'Minimal risks and constraints added by the research').
