Study summary

Numerous neurological disorders affecting the central and peripheral nervous system can be attributed to the immune system through multiple effector mechanisms. However, current treatments could be drastically improved by faster and more accurate diagnosis. The sample collection will benefit to patients with rare neuroimmune syndromes such as Autoimmune Encephalitis (AE) and Paraneoplastic Neurological Syndromes (PNS) leading to a better and early diagnosis, as well as treatment improvement.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
