Preferred Label : Anti-VISTA Monoclonal Antibody KVA12123;
NCIt definition : An engineered, human immunoglobulin (Ig) G1 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 KVA12123 targets and binds to VISTA on myeloid cells and T-cells within the
tumor microenvironment (TME). This inhibits VISTA-mediated signaling, decreases the
presence of monocytic myeloid-derived suppressor cells (MDSCs), increases the presence
of natural killer cells (NKs), activates dendritic cells (DCs) and abrogates VISTA-induced
suppression of T-lymphocyte immune responses. This enhances cytotoxic T-cell infiltration,
proliferation and activation within the 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.;
