Here, we investigated the immunostimulatory properties of FAP-IL2v and its combination with programmed cell death protein 1 (PD-1) checkpoint inhibition, CD40 agonism, T cell bispecific and antibody-dependent cellular cytotoxicity (ADCC)-mediating antibodies. The binding and immunostimulatory properties of FAP-IL2v were investigated in vitro and compared with FAP-IL2wt. Tumor targeting was investigated in tumor-bearing mice and in a rhesus monkey. The ability of FAP-IL2v to potentiate the efficacy of different immunotherapies was investigated in different xenograft and syngeneic murine tumor models. FAP-IL2v bound IL-2 R尾纬 and FAP with high affinity in vitro, inducing dose-dependent proliferation of natural killer (NK) cells and CD4+\/CD8+ T cells while being significantly less potent than FAP-IL2wt in activating immunosuppressive regulatory T cells (Tregs). T cells activated by FAP-IL2v were less sensitive to Fas-mediated apoptosis than those activated by FAP-IL2wt. Imaging studies demonstrated improved tumor targeting of FAP-IL2v compared to FAP-IL2wt. Furthermore, FAP-IL2v significantly enhanced the in vitro and in vivo activity of therapeutic antibodies that mediate antibody-dependent or T cell-dependent cellular cytotoxicity (TDCC) and of programmed death-ligand 1 (PD-L1) checkpoint inhibition. The triple combination of FAP-IL2v with an anti-PD-L1 antibody and an agonistic CD40 antibody was most efficacious. These data indicate that FAP-IL2v is a potent immunocytokine that potentiates the efficacy of different T- and NK-cell-based cancer immunotherapies.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAlternative Names\u003c\/b\u003e:FAP-IL2v, RO6874281\/RG7461\u003c\/p\u003e\u003cp\u003e\u003cb\u003eShipping\u003c\/b\u003e:2-8 ℃\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNote\u003c\/b\u003e:For Research Use Only.\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48655953789028,"sku":"DC440028","price":659.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_b25cc17e-1fe7-4cda-bd23-a183eb89e24e.jpg?v=1782808900","url":"https:\/\/www.genebiosystems.com\/en-gb\/products\/simlukafusp-alfa-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
