简要总结
Systemic Lupus Erythematosus (SLE) is a chronic, autoimmune, inflammatory disease primarily affecting women of childbearing age, and associated with severe morbidity and mortality of its victims. The existing therapy, however, is not specific and its inevitable side effects may themselves be fatal. Therefore, it is a widely recognized need for, and it would be highly advantageous to have a safe, specific rapidly effective and well-defined treatment of SLE, devoid of the disadvantages.
We have shown that VRT101 a peptide present in the extracellular laminin is a target for pathogenic lupus autoantibodies. Using this peptide we have developed the LupusorbTM - an immune-adsorption column which specifically binds pathogenic antibodies from monoclonal cultures as well as from patients' plasma. The investigational product named LupusorbTM Column is a sterile medical device for single use and can be classified into category IIb (synthetic ligands, peptides) according to Annex IX of the European Medical Device Directive 42/93/EEC.
The proposed study, a pilot non-randomized open label study, will test the safety, Tolerability and short term efficacy of a single immunoadsorption procedure in SLE patients.
