Could fewer plasma exchange sessions be just as effective for kids with brain inflammation?
NCT ID NCT07707739
First seen Jul 16, 2026 · Last updated Aug 25, 2026 · Updated 3 times
Summary
This trial tests whether plasma exchange (a blood-cleaning procedure) given every other day works as well as daily sessions for children with autoimmune encephalitis, a condition where the immune system attacks the brain. The study involves 22 children who are randomly assigned to one of the two schedules. The main goal is to see if both groups achieve similar improvements in daily functioning, measured by a standard disability scale.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Plasma exchange (PLEX) sessions
- What this could lead to
- If this trial succeeds, it could show that alternate-day plasma exchange works as well as daily sessions, reducing treatment burden for children with autoimmune encephalitis.
- What could go wrong
- This is a small, early-stage trial with only 22 participants, so results may not apply broadly. The study does not compare against no treatment or other therapies, limiting its impact.

Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Inclusion Criteria: * Childern diagnosed as autoimmune encephalitis according to Cellucci et al., 2020; acute/subacute onset (\<3 months) of encephalopathy with at least one of: new focal CNS findings, seizures, CSF pleocytosis, MRI suggestive of encephalitis, and supportive antibody testing when available. * Autoimmune encephalitis cases indicated clinically for PLEX as determined by the treating team (e.g., severe disease, refractory to steroids/IVIG or as part of first-line combination therapy). Exclusion Criteria: * Hemodynamic instability not amenable to plasma exchange. * Severe coagulopathy uncorrectable prior to PLEX (INR \>2 despite correction, platelets \<50,000/µL unless corrected). * Contraindications to central venous access placement. * Enrollment in another interventional trial that would interfere with the outcomes.
