Immunopharmacology Ligand
Comment: Efineptakin alfa is a long-acting immunoglobulin (Ig) fusion protein composed of recombinant human IL-7 fused to a hybrid Fc (hyFc) region of a human antibody. It comprises two disulphide bond-linked peptide chains. Efineptakin alfa has hematopoietic and immunopotentiating activities. In the oncology setting IL-7 enhances T-cell-mediated anti-tumour immune responses. Efineptakin alfa is being developed by Genexine (in-licensed to I-MAB Biopharma) and NeoImmuneTech. The peptide sequence of efineptakin alfa is claimed in Genexine's patent WO2016200219A1 as sequence 24 and would appear to be referred to as MGM-IL-7-hyFc therein [3].
