ABOUT
Anti-human CD40L - Frexalimab biosimilar - CAS #2515463-86-0
Anti-hCD40L-hIgG1 is a biosimilar antibody of Frexalimab, a human CD40 ligand (CD40L) antibody that specifically blocks the binding between CD40L to its receptor CD40. This monoclonal antibody (mAb) shows promising results across multiple trials in treating various autoimmune diseases, such as relapsing multiple sclerosis, alleviating fatigue in primary Sjögren’s syndrome, and improving glycemic control in diabetic patients.
Anti-hCD40L-hIgG1 comprises the variable region of Frexalimab and the IgG1 constant region of Frexalimab, mediating high effector functions.
This antibody can be used together with HEK-Blue™ CD40L cells for screening and neutralization assay to block CD40L signaling induced by recombinant human CD40L (see figure).

Details
Frexalimab and CD40L background
Frexalimab (SAR441344) is a second-generation monoclonal antibody targeting the CD40 ligand (CD40L). It is designed to specifically block the binding between CD40L and CD40 [1].
CD40 Ligand (CD40L), also known as CD154, TRAP, or gp39, is a type II transmembrane glycoprotein belonging to the tumor necrosis factor (TNF) family. It is mainly expressed in CD4+-T cells and interacts with CD40 on antigen-presenting cells to regulate both humoral and cellular immune responses [2-3]. The CD40 cytoplasmic domain binds directly to several TNF receptor-associated factors (TRAFs), and this interaction is thought to initiate CD40 signaling. CD40-mediated signaling results in NF-κB, c-Jun N-terminal kinase (JNK), and p38 mitogen-activated protein kinase (MAPK) activation.
CD40L-CD40 interactions are thought to play an important role in the pathogenesis of many diseases [5, 6]. Thus, blocking this interaction using agents, such as Frexalimab, has shown promising results across multiple trials in treating various autoimmune diseases, such as relapsing multiple sclerosis, alleviating fatigue in primary Sjögren’s syndrome, and improving glycemic control in diabetic patients [1].
