Background
Inbakicept is a dimeric human IL-15 receptor alpha (IL-15 Ra) sushi domain/human IgG1 Fc fusion protein and is an IL-15 superagonist complex. Inbakicept is able to form complex N-803 (Nogapendekin alfa inbakicept) with the IL-15 antibody Nogapendekin alfa in a 1:2 ratio. N-803 mimics the function of IL-15 and amplifies anti-CD20 mAb-mediated NK cell responses and antibody-dependent cellular cytotoxicity (ADCC). N-803 also increases degranulation and IFNγ production in cells.• Exercise-induced engagement of the IL-15/IL-15Rα axis promotes anti-tumor immunity in pancreatic cancer., PMID:35660135• Interleukin 15: A key cytokine for immunotherapy., PMID:27325459• IL-15 in the Combination Immunotherapy of Cancer., PMID:32508818• IL-27 enhances IL-15/IL-18-mediated activation of human natural killer cells., PMID:31277710• Interleukin-15 in autoimmunity., PMID:32919253• Interleukin-15-armoured GPC3 CAR T cells for patients with solid cancers., PMID:39604730• An engineered concealed IL-15-R elicits tumor-specific CD8+T cell responses through PD-1-cis delivery., PMID:36165896• IL-15, gluten and HLA-DQ8 drive tissue destruction in coeliac disease., PMID:32051586• Engineering NK-CAR.19 cells with the IL-15/IL-15Rα complex improved proliferation and anti-tumor effectin vivo., PMID:37818365• Systemic IL-15 promotes allogeneic cell rejection in patients treated with natural killer cell adoptive therapy., PMID:34797911
