Abetimus
Abetimus (trade name Riquent) is an immunosuppressant.[1] It is a synthetic biological called a tolerogen. It is made of four double-stranded oligodeoxyribonucleotides that are attached to a carrier platform and are designed to block specific B-cell anti double stranded DNA antibodies.[2] It may also complex anti dsDNA antibodies together, therefore disabling them. This way abetimus was supposed to help treat systemic lupus erythematosus and specifically lupus nephritis.
