Preferred Label : Anti-VISTA Monoclonal Antibody HMBD-002;
NCIt definition : An immunoglobulin G4 (IgG4) monoclonal antibody directed against the negative immune
checkpoint regulatory protein V-domain Ig suppressor of T-cell activation (VISTA;
programmed death 1 homolog; PD1H; PD-1H), with potential negative immune checkpoint
regulatory and antineoplastic activities. Upon administration, anti-VISTA monoclonal
antibody HMBD-002 targets and binds to VISTA on monocytes and T-cells. This inhibits
VISTA-mediated signaling, decreases the presence of monocytic myeloid-derived suppressor
cells (MDSCs), increases the presence of activated dendritic cells (DCs) and abrogates
VISTA-induced suppression of T-lymphocyte immune responses. This enhances cytotoxic
T-cell infiltration, proliferation and activation within the tumor microenvironment
(TME), increases cytokine production by T-cells, and inhibits tumor cell growth. VISTA,
a negative checkpoint molecule of immune activation, is highly expressed on myeloid
cells, T-cells and in several tumor types. It plays a key role in the suppression
of T-cell function.;
