Olamkicept, also known as soluble gp130Fc or sgp130Fc (other designations are FE 999301, FE301, TJ301) is an immunosuppressive drug candidate, which selectively blocks activities of the cytokine Interleukin-6, which are mediated by the soluble Interleukin-6 receptor. Interleukin-6 is a cytokine, which plays a dominant role in the regulation of the immune response and also in autoimmunity. Furthermore, Interleukin-6 has been demonstrated to be involved in the regulation of metabolism and body weight. Interleukin-6 also has many activities on neural cells. The biochemical principle was invented by the German biochemist Stefan Rose-John and it was further developed into a biotech compound by the Conaris Research Institute AG, which gave an exclusive world-wide license to the Swiss-based biopharmaceutical company Ferring Pharmaceuticals. In December 2016, Ferring and the biotech company I-MAB signed a licensing agreement granting I-MAB exclusive rights in Asia to Olamkicept for the treatment of autoimmune disease.
