EMA APPROVED, 2020/8/25, Idefirix

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, brand name Idefirix, is a medication for the desensitization of highly sensitized adults needing kidney transplantation, but unlikely to receive a compatible transplant.[1]

Imlifidase is a cysteine protease derived from the immunoglobulin G (IgG)‑degrading enzyme of Streptococcus pyogenes.[1] 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).[1] Thus, imlifidase reduces the level of donor specific antibodies, enabling transplantation.[1]

The benefits with imlifidase are its ability to convert a positive crossmatch to a negative one in highly sensitized people to allow renal transplantation.[1] The most common side effects are infections and infusion related reactions.[1]

In June 2020, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) recommended the approval of Imlifidase.[1][2]

Medical uses

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.[1] 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.[1]

History

Imlifidase was granted orphan drug designations by the European Commission in January 2017, and November 2018,[3][4] and by the U.S. Food and Drug Administration (FDA) in both February and July 2018.[5][6]

In February 2019, Hansa Medical AB changed its name to Hansa Biopharma AB.[4]
