    NKTR-262: Discovery of a novel TLR 7/8 agonist prodrug that demonstrates synergistic anti-tumor effect in combination with NKTR-214, a CD-122 preferential IL-2 pathway agonist (204B, Pennsylvania Convention Center) -  Feb 13, 2020 - Abstract #ACSSp2020ACS_Sp_10556;    
    We hypothesized that combination treatment with NKTR-262 and NKTR-214 could provide powerful and synergistic anti-tumor effects as NKTR-262 could potentiate the antigen-presenting cells and convert M2 macrophages to M1 macrophages, and NKTR-214 could stimulate expansion of “educated” CD8+ T cells, which then traffic to distant tumor sites resulting in tumor shrinkage.In preclinical studies, a single intratumoral administration of NKTR-262 combined with systemic administration of NKTR-214 produced a complete cure of treated and untreated tumors in multiple syngeneic models. Currently, NKTR-262 is being evaluated in a Phase 1b/2 clinical trial in patients with locally advanced or metastatic solid tumors.
