Comparing immunoadsorption and immunoglobulins for treating CIDP

Immunoadsorption Versus Immunoglobulins for Treatment of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

PHASE2 · University of Ulm · NCT04881682

This study is testing whether a new treatment called immunoadsorption works better than immunoglobulin for people with CIDP who haven't improved with other medications.

What this trial studies

This clinical trial is a randomized controlled study that evaluates the safety and efficacy of repeated immunoadsorption compared to immunoglobulin treatment in patients with steroid-refractory Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). The study focuses on individuals diagnosed with CIDP who have not responded adequately to previous treatment with methyl-prednisolone. Participants will be monitored for their response to the two different treatment approaches over the course of the trial.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a diagnosis of CIDP and insufficient response to methyl-prednisolone.

Not a fit: Patients with active systemic infections or those who have contraindications to immunoadsorption or immunoglobulin therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with CIDP who do not respond to standard therapies.

How similar studies have performed: While there have been studies on immunoglobulins for CIDP, the specific comparison of immunoadsorption versus immunoglobulins in this context is a novel approach.
