Immunoadsorption for Treatment of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

University of Ulm · NCT07154524

This observational study will try immunoadsorption as a next-step treatment for adults with CIDP who do not respond well to IVIg or methylprednisolone.

What this trial studies

This is a multicenter, observational exploration enrolling about 140 adults with CIDP within the German Kompetenznetz Peripherer Nerv (KKPNS). Participants who are on or starting IVIg or methylprednisolone may be switched to immunoadsorption (IA) during an 18-month observation period if their response is insufficient. IA will be used as escalation therapy according to each center's therapeutic scheme, with a non-mandatory recommendation on session number, volumes, and frequency. Six-month follow-up visits and clinical outcome tracking will be used to collect safety and effectiveness information.

Who should consider this trial

Good fit: Adults (age ≥18) with CIDP diagnosed per EAN/PNS criteria who are currently receiving or starting treatment with IVIg or methylprednisolone are eligible.

Not a fit: Patients who already have an adequate clinical response to IVIg or methylprednisolone are unlikely to benefit from switching to IA.

Why it matters

Potential benefit: If successful, IA could offer better symptom control for patients who do not respond to IVIg or methylprednisolone, with fewer complications than conventional plasma exchange.

How similar studies have performed: Previous case series and nonrandomized reports suggest IA can be effective and better tolerated than plasma exchange, but randomized controlled evidence is limited.
