"PROJECT":{"PROJECT_TITLE":"Simultaneous targeting of PD-1 and IL2Rβγ with radiation therapy to inhibit pancreatic cancer growth and metastasis","PROJECT_SUMMARY":"In pancreatic ductal adenocarcinoma (PDAC) patients, we show that response to radiation therapy (RT) is characterized by increased IL2Rβ and IL2Rγ and decreased ILR2α expression. The bispecific aPD1-IL2v is a PD-1-targeted IL-2 variant (IL2v) immunocytokine with engineered IL-2 cis-targeted to PD-1 and abolished IL2Rα binding, which enhances tumor-antigen specific T cell activation while reducing regulatory T cell (Treg) suppression. Using aPD1-IL2v in orthotopic PDAC KPC-driven tumor models, we show marked improvement in local and metastatic survival along with profound increase in tumor-infiltrating polyfunctional CD8+ T cell subsets with a transcriptionally and metabolically active phenotype, and preferential activation of antigen-specific CD8+ T cells. In combination with single dose RT, aPD1-IL2v treatment results in a robust, durable expansion of polyfunctional CD8+ T cells, T cell stemness, tumor-specific memory immune response, natural killer (NK) cell activation, and decreased Tregs. These data show that aPD1-IL2v leads to profound local and distant response in PDAC.","INSTITUTE":"University of Colorado Denver","LABORATORY":"Lab of Angelo D'Alessandro in collaboration with lab of Sana Karam","LAST_NAME":"Haines","FIRST_NAME":"Julie","ADDRESS":"12801 E 17th Ave, Room 1303, Aurora, Colorado, 80045, USA","EMAIL":"julie.haines@cuanschutz.edu","PHONE":"3037243339"},

"STUDY":{"STUDY_TITLE":"Simultaneous targeting of PD-1 and IL2Rβγ with radiation therapy to inhibit pancreatic cancer growth and metastasis - mouse serum metabolomics","STUDY_SUMMARY":"Mice were orthotopically implanted with PK5L1940 cells then radiation therapy (8 Gy) administered 7 days post-implantation. PD1-IL2v and aCD25 dosed once per week beginning day 7 post-implantation. Serum was collected at time of sacrifice and profiled by mass spectrometry-based metabolomics to visualize changes in systemic metabolism in the mouse model.","INSTITUTE":"University of Colorado Denver","LAST_NAME":"Haines","FIRST_NAME":"Julie","ADDRESS":"12801 E 17th Ave, Room 1303, Aurora, Colorado, 80045, USA","EMAIL":"julie.haines@cuanschutz.edu","PHONE":"3037243339"},
