anti-CD40L Fc-fusion protein BMS-986004
A dimeric fusion protein composed of the C-terminus of the domain antibody (dAb) BMS2h-572-633 targeting the CD40 ligand (CD40L or CD154) linked to a modified Fc fragment of immunoglobulin G1 (IgG1), with potential immunomodulatory activity. Upon intravenous administration, the peptide moiety of anti-CD40L antibody BMS-986004 specifically targets and binds to CD40L expressed on T lymphocytes. This prevents the binding of CD40L to its cognate receptor CD40 expressed on B lymphocytes, macrophages, and dendritic cells (DCs). This prevents T-cell mediated proliferation and differentiation of B cells, and prevents the production of antibodies. By inhibiting both the production of anti-glycoprotein (GP) IIb/IIIa antibodies by B cells and GPIIb/IIIa-dependent T-cell proliferation, BMS-986004 may prevent platelet destruction and may increase platelet counts in idiopathic thrombocytopenic purpura (ITP). The direct binding of BMS-986004 to CD40L on platelets further prevents CD40L/CD40-mediated destruction by macrophages and DCs in ITP. The modified Fc domain prevents the binding of BMS-986004 to the Fc receptor FcgammaRIIA on platelets, thereby preventing FcgammaRIIA-dependent platelet activation and anti-CD40L-induced thromboembolism. CD40L, a transmembrane protein of the tumor necrosis factor (TNF) superfamily, is primarily expressed on activated T cells, but is also expressed on eosinophils, basophils, natural killer (NK) cells, mast cells, platelets and activated endothelial cells. Check for active clinical trials using this agent. (NCI Thesaurus)
