Blood filter shows promise for autoimmune patients
NCT ID NCT04078698
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at a device called GLOBAFFIN that filters antibodies from the blood to help people with autoimmune diseases. It involved 34 adults and measured how much harmful antibodies were removed and if patients felt better. The goal was to see if the device is safe and works well in everyday medical practice.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GLOBAFFIN immunoadsorber (a device that filters antibodies from the blood)
- What this could lead to
- If successful, this could confirm that the GLOBAFFIN device is a safe and effective way to manage autoimmune diseases by removing harmful antibodies.
- What could go wrong
- This is a small, completed observational study with only 34 patients, so results may not apply to everyone. It does not compare the device to other treatments, so its true benefit is uncertain.

Inclusion Criteria: * Minimum age of 18 years * Informed consent signed and dated by study patient and investigator/authorised physician * Ability to understand the nature and requirements of the study * Treatment with one of the immunoadsorber system GLOBAFFIN® according to the intended use. Exclusion Criteria: General: * Any condition which could interfere with the patient's ability to comply with the study * In case of female patients: pregnancy or lactation period (if patient is ≥ 55 years old or have been surgically sterilized, a negative pregnancy test is not required) * Participation in an interventional clinical study during the preceding 30 days. * Participation in an interventional clinical study with pharmacological active substances (e.g. therapeutic antibodies) during the preceding 60 days. * Any deviation from the intended use Study-specific: Any contraindication listed in the valid instruction for use: * Hypersensitivity or allergy against any materials used in either the immunoadsorber column or the extracorporeal circuit * Inability to withstand the stress of an extracorporeal treatment procedure due to their age, their physical developments or their clinical constitution * Previously demonstrated hypersensitivity associated with therapeutic apheresis * No suitable anticoagulation treatment, such as due to known hypersensitivity to heparin or ACD-A * Haemorrhagic diathesis in which extracorporeal apheresis procedures and anticoagulation performed have a high bleeding hazard * Severe cardiovascular disease, so that extracorporeal treatment is not possible * Acute, systemic infection
