Neuromyelitis Optica Spectrum Disorder Rare and debilitating disease with unmet medical need NMOSD (previously known as Devic’s disease) is a severe and rare autoimmune disease characterized by debilitating relapse/attacks, which often leads to blindness and paralysis Data suggest that NMOSD is a B cell-mediated disorder 1, resulting from: Pathologic autoantibody production Pro-inflammatory cytokine secretion B cell antigen presentation Disease mostly driven by autoantibody against aquaporin 4 (AQP4) with ~80% of patients testing seropositive for AQP4-IgG Prevalence 2: U.S. - 1 to 5 per 100,000; ~10,000 patients E.U. - 1 to 7 per 100,000; ~8,000 patients Japan - 4.1 per 100,000; ~5,000 patients 1) Bennett JL, et al.

VIB4920: Novel Therapy to Address Immune Overactivation Originating in Co-Stimulatory Pathway T cells interact with B cells, macrophages and endothelial cells through various co-stimulatory receptor-ligand interactions, including CD40/CD40L CD40L considered important component of immune responses involved in B cell activation, maturation and eventually antibody production Research suggests potential benefits of targeting the CD40L/CD40 interaction in autoimmune diseases such as lupus nephritis and idiopathic thrombocytopenic purpura when using full antibodies directed at CD40L Earlier generation CD40L mAb observed thromboembolic side effects CD40/CD40L co-stimulatory pathway Germinal Center Formation Dendritic Cell Activation Macrophage Function

Slide 20

VIB4920 Overview VIB4920 is a fusion protein designed to bind to CD40L on activated T cells, which is intended to prevent B cells from differentiating into plasma cells and memory cells VIB4920 also inhibits stimulation of dendritic cells and monocytes by T cells, which reduces production of pro-inflammatory mediators VIB4920 avoids platelet aggregation since Tn3 is a small protein scaffold that does not possess an Fc domain and therefore is unlikely to induce adverse platelet responses No adverse platelet findings from completed Phase 1 SAD and decreased disease activity from Phase 1 MAD trial in rheumatoid arthritis patients Tn3, Tenascin-3
