Nogapendekin alfa inbakicept (Anktiva)
Mechanism of action
From the NCI Drug Dictionary: A fusion protein complex composed of a mutated form of the cytokine interleukin (IL)-15 (IL-15N72D) and a soluble, dimeric IL-15 receptor alpha (IL-15Ra) Fc fusion protein (IL-15Ra-Fc) (IL-15N72D/IL-15Ra-Fc), with potential antineoplastic activity. Upon administration, superagonist interleukin-15:interleukin-15 receptor alphaSu/Fc fusion complex N-803 binds to the IL-2/IL-15 receptor beta-common gamma chain (IL-2Rbetagamma) receptor on natural killer (NK) and CD8+ T lymphocytes, which activates and increases the levels of NK cells and memory CD8+(CD44high) T cells. The memory T cells enhance the secretion of the cytokine interferon-gamma (IFN-g), which further potentiates the immune response against tumor cells. This may increase tumor cell killing and decrease tumor cell proliferation.
