Efgivanermin Alfa Biosimilar Fusion Protein (GITR) for Research

Pre-Made Efgivanermin Alfa Biosimilar, Fusion Protein targeting TNFRSF18 fused with human IGHG1 Fc (Fragment constant): Recombinant therapeutic protein targeting AITR/CD357/ENERGEN/GITR/GITR-D is a biosimilar expressed by mammalian cell line as a benchmark reference therapeutic antibody for biological drug disovery items including cell culture, assay development, animal model development, PK/PD model development (Pharmacokinetics & Pharmacodynamic) and mechanism of action (MOA) research.

Efgivanermin alfa is a homogenous hexameric agonist fusion protein composed of the extracellular domain (ECD) of the T-cell costimulatory receptor human glucocorticoid-induced tumor necrosis factor receptor (tumor necrosis factor superfamily, member 18; TNFRSF18; GITR) ligand (GITRL) and an immunoglobulin (Ig) G1 Fc domain, with potential immunomodulating and antineoplastic activities. Efgivanermin alfa binds to and activates GITR found on multiple types of T cells, thereby inducing both the activation and proliferation of tumor antigen-specific T-effector cells. This abrogates the suppression of T-effector cells which is induced by inappropriately activated T-regulatory cells (Tregs), suppresses Tregs and decreases Treg tumor infiltration, and activates the immune system to help eradicate tumor cells. GITR, a member of the TNF receptor superfamily, is expressed on the surface of multiple types of immune cells, including Tregs, effector T cells, B cells, dendritic cells (DCs) and natural killer (NK) cells.
