Pre-transplant treatment to make patients with donor specific IgG eligible for kidney transplantation
Immunosuppressant, Immunoglobulin modulator (enzyme)
Imlifidase is under investigation in clinical trial NCT02854059 (IdeS in Asymptomatic Asymptomatic Antibody-Mediated Thrombotic Thrombocytopenic Purpura (TTP) Patients).
Imlifidase is a cysteine protease derived from the immunoglobulin G (IgG)‑degrading enzyme of Streptococcus pyogenes. It cleaves the heavy chains of all human IgG subclasses (but no other immunoglobulins), eliminating Fc-dependent effector functions, including CDC and antibody-dependent cell-mediated cytotoxicity (ADCC). Thus, imlifidase reduces the level of donor specific antibodies, enabling transplantation.
The benefits with imlifidase are its ability to convert a positive crossmatch to a negative one in highly sensitized people to allow renal transplantation. The most common side effects are infections and infusion related reactions.
Per the CHMP recommendation, imlifidase will be indicated for desensitization treatment of highly sensitized adult kidney transplant people with positive crossmatch against an available deceased donor. The use of imlifidase should be reserved for people unlikely to be transplanted under the available kidney allocation system including prioritization programmes for highly sensitized people.
Imlifidase was granted orphan drug designations by the European Commission in January 2017, and November 2018, and by the U.S. Food and Drug Administration (FDA) in both February and July 2018.
In February 2019, Hansa Medical AB changed its name to Hansa Biopharma AB.
